A Possible Cause of Power Bank Fires

Given the random exploding or catching of fire of power banks on flights, airlines have either banned or restricted the carrying of power banks to hand luggage only.

According to an interesting article by Andrew Hirst in 2021, there were about 340 lithium battery related incidents on flights (presumably in the US only?) between January 2006 and August 2021.

I read a dozen or more random articles around this. Almost all of them ranged the causative factors from poor quality battery packs, to pressurized cabins on aircraft, to the possibility of the power bank getting dropped, damaged or crushed by luggage contents or by any heavy weight placed over them, as possible reasons.

However, I could not find one possibility on any of those articles.
Could users be plugging the power bank’s cord back into itself for convenience when traveling?

Based on the little reading I did on the matter, power banks have an operating range of around 3.7-4.2 Volts.
However, mobile phones need 5V to be charged. So when you plug your power bank to charge your phone, the power bank’s circuitry boosts that 3.7 odd Volts to 5V, also causing an energy-loss of 10-15%.

In theory, this also means that if you connected both ends of the cord to the power bank, while it would charge and discharge itself, due to the energy loss, it would discharge itself soon.

However, until that happens, I would assume that the 5V output voltage going back in the lower volt input, could cause its temperature to increase? Ever plugged a 120V product into a 240V outlet and seen smoke come out of the adapter?
Could that be a cause of the instances when power banks catch fire on flights? Perhaps in a work or home environment, users might not be as particular about the free end of the power cord as much as when they travel and would like the cord to still be with the power bank, wherever the their luggage the power bank might end up being shuffled around to.

Because if that is the case, it might simplify airline restrictions and checking to some extent, and the airline (and public service messages) could simply ask people not to plug both ends of the cord into the power bank when it is not in use.

On Seeking Advice

pensive grandmother and granddaughter having a conversation while cooking in the kitchenImage: source

When seeking advice, especially from someone you believe can offer great perspective, stick to gaining clarity on the big questions you need help figuring out.
The advice you receive is obviously for you to consider, not to blindly implement.
And especially not for you to defend when receiving it.

Clarify if you think something was misunderstood. I have observed a good number of people claim to seek advice, but the moment the people they seek advice from points out an improvement area, they try to defend it and start chatting about it.
That is usually the ego’s defenses kicking in, which is natural. However, when we try defending and chat about it, that distracts and diverts focus from that very aspect of our behaviour that we hope to improve on (and why we seek advice for).

When I seek advice, I consider the duration of the meeting or interaction as a time to be quiet.
Start with your most important question.
A good person to seek advice from would ideally ask you more questions for context before jumping to ‘advice’.
Counterintuitively, be wary of those who jump to advising with little knowledge about your context.

And every once in a way, you add more questions or course correct, if you feel the challenge you’ve sought help on has not been accurately understood or has been addressed incorrectly.

But apart from that, seeking advice should be about attentive listening, note-taking, and hopefully getting a new way to look at the challenge, and some ways to take a shot at it.

It should not be like a casual conversation with a friend just for the kicks of relieving the pressure or discomfort from it, though if you choose the people you seek advice from well, the conversation will have that effect on you as an incidental benefit.

Product Design should factor Human Forgetfulness

Product design should factor for human forgetfulness where possible.

This is a picture of the detergent tray from a leading brand, top-loading washing machine.

The hole in the tray is where detergent, mixed with water, drips into the drum during a wash cycle.

However, when the tray is opened to fill detergent, you notice it slopes downward.

This is understandable from a manufacturer’s perspective, the reason for the downward slope of the open tray intended to prevent any liquid or diluted detergent dripping into the drum before the cycle has begun.

However, from the user’s perspective, it also means that if a user forgets to shut the tray, it will fill with water, but mostly likely won’t drip through the outlet, as you can see in this case where, shortly after starting the cycle, it was realized and shut.

And forgetting to close the tray can be a very likely possibility in the hurried world we live in. It would involve an extra wash cycle after one realizes. And more water wasted, to get the job done.

A less desirable workaround solution could involve a sensor check that alerts the user of an open tray.
A intuitive workaround could be where the tray tilts forward (instead of backward), and the outlet is placed on the lower end, and only opens during a cycle and not before. So as not to inconvenience the user.

After all, aren’t machines supposed to be designed to make human lives more efficient?

An Indian Survivorship Bias Example

Many of you must have seen that drawing of a World War II plane with red dots on it.

It explains Survivorship bias, a bias that statistician Abraham Wald figured out.

Pic: source

Simply put, survivor bias is our tendency to view a situation or pattern as a comprehensive representative sample, often without considering what might be missing from that picture.

For instance, the WWII plane with red dots was a study Wald and his team carried out to determine which parts of returning Allied jets were hit the most by enemy gunfire, so as to reinforce those parts and make them stronger.

It was then that Wald realized that those parts were actually stronger, as all those jets had made it back to base safely. So instead, they focused on reinforcing the other parts, since clearly jets hit on other weaker sections never survived to tell their side of the story.

In India, there has been a belief among many of the older folk that children or people with big/long ears live a longer life, compared to those with smaller ears.

Interestingly, while most of our body shrinks with age, our nose, earlobes and ear muscles keep growing. Which means our elders had the concept backwards.

It was not that those born with bigger ears lived longer. But rather that those who lived longer, had ears that simply had a longer time to keep growing, and are therefore, relatively bigger in size.

Product Design Inputs for a Standing Desk

Invisible Bed has been an interesting product company.
As a recent owner of a wall mounted sit/ stand desk, I recently shared some product design inputs with the CEO. They were well received.

The Product:

The Challenge:
1.Pre-attached table-top – makes installation a challenge even for a 2-person team, as the table-top weight causes the swing-arms to open
What I would do instead:
Keep the table-top separate. Maybe include a clamp on the swing-arms, onto which the table-top can subsequently be clamped onto. This might prevent the swing-arms from constantly opening.

2.Desk design – causes the unit in fully–collapsed position to swing outward and downward when unlocked. And the locking mechanism deforms if the desk is inadvertently lifted without unlocking – either way, risks injury to users or children who unlock it and are in the path when it swings outward
What I would do instead:
Offset the design so that the center of gravity falls within the unit itself, preventing it from swinging outward. It would then need to be manually lifted into position by the user, also automatically reducing the possibility of small children getting hurt as the unit would not swing open even if unlocked.
Or alternatively (simpler but boring option), a stronger locking mechanism.

This idea was part of an initiative called RattL ’em. and was shared with the CEO of the company, who was thrilled with the inputs, and plans to incorporate it in the future design.

What is RattL ’em?: We are constantly fascinated by companies, products and services.
So whenever a company catches our curiosity, we offer them an idea (a new product, service, or feature/ improvement idea), or highlight a concern area. Someday, we hope we can send an idea out into the world everyday.
We do this for free, and for fun. And the company receiving the idea is free to use it, with no financial or other obligation toward us. It is our way of trying to be the best in the field of people innovation.

Everything as a Service

Over the past decade, the business world has had a real attraction to making everything a service. And rightly so. Would you rather struggle to repeatedly sell your product to the same customer? Or would it be better to offer it on a subscription model where you can keep improving it over time, and charge users a regular fee for using it? From furniture and tech products to cars, web hosting and food apps. I’m all for the services model.
 
However, you can’t help compare the process of buying good ol’ products whenever you would need them, to subscription based services. Let me know what you think..
 
In FMCG products, larger SKUs are more expensive, but (almost) always cheaper per unit than smaller quantity SKUs.
Increased manufacturing, distribution costs, and profit margins affect the price of a product. But that price applies to all customers, new or loyal ones. As does any promotion, that does not differentiate between old and new customers.
 
Compare that with technology and web service companies. You pay a monthly, quarterly or annual fee for services they offer. Technology companies, like any other business, have costs that tend to grow over time. And their discounts to convert free-, or non-users to paid users are far more tempting than consumer product discounts. Rightly so.
 
But these discounts strain the operations of many of these tech companies, forcing them to create lean models of operations. That’s the upside! Is anything more fascinating than Uber needing only a 3-member team to manage every new location it expands to?
 
But once that discount period is over, fees of many tech services companies goes up, year after year. And similar to consumer product customers, there is no growing advantage of staying loyal (apart from a superior offering itself) to a brand. While customers of consumer products still benefit from any benefits offered to new/ non-paying customers, that often does not happen with tech services companies.
 
And therein lies the anomaly. Alert consumers of a tech service would find themselves reviewing the service and its benefits, comparing with competitors, or even just weighing the pros and cons of retaining any such service, each time it is up for renewal.
 
I’ve been using the MS Office 365 service for almost 8 years, and the older MS Office software before that. And while my subscription was on auto-renewal for many years, at one point I realized how the fee had steadily risen. While new users were still getting it at a price almost 40% lower (and as a friend mentioned, even lower on Amazon on festival days). It seemed unfair, and there was nothing stopping me from simply registering as a new user with a new email id, and simply moving files from one cloud to another.
 
Similarly, hosting is a ruthless market for service providers. All service providers offer heavy discounts on new subscriptions, but those fees skyrocket once that initial period is over. And in many cases, you don’t want to avail the heavy discount and commit to many years subscription without knowing the quality of the service and support.
 
I wonder if this anomaly seems more in price-sensitive markets like India, or it is a pattern across the world.
 
And I wonder if there is a better model that might help fix this apparent anomaly (for customers) and challenge that service companies face. One that is adequately fair to the service companies that work hard to bring incredible services our way, and to stand apart from the competition. And that is also fair to the average user of those services who is not thrilled about being fleeced for a service he or she has been using loyally for sometime, and then finding out that it is being offered to newcomers at a fraction of the cost they pay – with no extra benefits to show for the loyalty.
 
The ideal model would be one that adequately compensates tech service companies, while also avoiding the highly skewed pricing between newbies and loyalists. And tech companies need to lose any fat.
 
I am always reminded of Uber and Ola. It is popularly known that Uber just needs a 3-member team to expand to a new city. And in 2012, I remember forgetting an empty gym bag in an Ola cab, and ended up being sent to two of their sprawling offices in Mumbai!
 
The business model that extends from the founders’ vision and extends to become part of the culture of the organization, will determine how soon and how much profits your business can and will make.

Could Musical Roads address Global Speeding and Road Safety


Pic: source

There are roads in Hungary that plays music!
A musical road was first created in 1995 Denmark, by two artists. Given how brilliant a concept, I wonder why its Danish origins seem almost obvious. Just like the concept of hygge and especially Lego.

Musical roads also exist in other countries like Hungary, Japan, South Korea, the United States, China, Iran, Taiwan, and Indonesia. Many of these are either created by artists, or as in the case of Hungary, in memory of an artist. The Japanese interestingly stumbled upon it by a fortunate accident involving engineer Shizuo Shinoda, who unintentionally scraped some markings on the road with a bulldozer. Driving over that section created tunes.
[Read more on musical roads here].

Once you get past the amazement of musical roads in general, you can’t help realize the possible solution it presents for controlling speed on roads and highways across the world.

Imagine popular tunes are recreated onto roads notorious for speeding. Anyone going faster or slower than the popular tune that a road plays, which would be adapted for the speed range on that road, riding or driving outside that range would simply sound..wrong.
And it might nudge you to adjust your speed to within the prescribed limit! 💡

If the installations are affordable and convenient to install/remove, they could be updated with the latest tracks regularly, to keep up with times.

Another aspect that might contribute to its possible effectiveness is the fact that unlike the car music system, it cannot be turned off. The flipside of course, is the possibility of teens (the usual suspects and culprits of speeding) intentionally speeding to make the tune sound funny.

A subsequent study could perhaps look into finding any correlations between those who tend to speed, and those who don’t have a ear for music… 😉

How About a Mass Behavioural Improvement before India’s 100th Independence Day

 


The beautiful tri-colour waving at Connaught Place, Central Park, Delhi.

It’s 75 years since India got Independence!
A proud milestone for all of us Indians. Also one to reflect on and carefully choose the path forward.

I happened to read a 75th Independence Day post on Instagram a short while ago, that took a crude jab at the Brits.
What I found amusing is I believe it captures a common trait among many of us Indians.

This is obviously not a political post. It is a behavioural one though.

It has been 75 years!
Our media never misses an opportunity to find Indian connections to the Royal family..
There’s a massive Indian population living in the UK..
We dream of holidaying in the UK..
We dream of owning cars and motorbikes from the UK region..

..but still have this unaddressed anger of sorts. I mean come on, it has been 75 years ffs!

Thing is, I have experienced this type of misplaced emotion myself as well.
As a 7-8 year old, one of the early deaths of a loved one was that of my grandfather. He had already suffered a stroke, and subsequently died of a heart attack.

I remember struggling to come to terms with it, and told a cousin that I wish a person had caused it, so that perhaps I could find a rational channel for my anger and more importantly my sadness.

So I wonder, is it something broken in our education system, or in how we bring up our children, not discussing or not knowing how to discuss tough or uncomfortable topics, that causes us to grow up to become anger-filled, cynical adults who, as Steve Buscemi (Garland Greene in Con Air) describes someone saying,
“He’s a font of misplaced rage.
Name your cliche. Mother held him too much, or not enough.
Last picked at kick ball, late-night sneaky uncle. Whatever.
Now he’s so angry, moments of levity actually cause him pain.”

And this is not just the case with India. Other countries around the world, some in Europe and South America too, display a similar general trend of latent anger or cynicism amongst its people.

Better understanding of this behavioural pattern might help us address it, so we can reach our true potential, as individuals, and as a country. Let us improve multi-fold by our 100th Independence Day.

 

 

 

 

Mobile Apps and Habits


Pic: source

If you are trying to create a new habit or trying to use a mobile app more regularly, you would obviously have better luck if you placed the app on the Favourites row. It could be a planner app, an e-book reader, a food-tracking or exercise app, or whatever else.

But it is possible that row is limited and filled with other important apps like the caller app, browser, camera, etc.

So in case you use a page-type layout for apps, the next best option after the Favourites row, is to place that important app in the row just above the Favourites row or in the top row. Because either of these is where your general gaze goes to each time you look at your phone.

If you use a Menu layout with apps (or app folders) on a vertically-scrolled grid, you might be better off placing the important app in the absolute middle row, or the topmost or lowest row.

When you use your phone the next few times, observe which section (top, or lower) of the phone you pay attention to.
Or without checking on your phone, try to think of one or more apps that you think are on the top and bottom (one above Favourites) row on your phone. Placing the important app in that row will remind you to use that app more regularly.

If you aren’t in the habit of rearranging the layout of apps on your phone, key apps that you believe might help you improve on some front, will have a greater tendency to remain downloaded but forgotten or seldom used.

Questions and thoughts welcome.
