Word of the day- pokayoke

pokayoke!

Poka-yoke (ポカヨケ?) [poka yoke] is a Japanese term that means "mistake-proofing". A poka-yoke is any mechanism in a lean manufacturing process that helps an equipment operator avoid (yokeru) mistakes (poka). Its purpose is to eliminate product defects by preventing, correcting, or drawing attention to human errors as they occur.The concept was formalised, and the term adopted, by Shigeo Shingo as part of the Toyota Production System.It was originally described as baka-yoke, but as this means "fool-proofing" (or "idiot-proofing") the name was changed to the milder poka-yoke.

Thoughts on better making

Ideas for better engineering. I’m very passionate about applied and analytical material science with a background in leading startup initiatives. I had built a haptic wearable startup with synthesis gait analysis and haptic feedback through wearables, which exposed me to several schools of design and engineering, and on-ground impact. This had bought me to Boston at MIT to explore advanced forms of man-machine-interfaces. I have transcended from just being a techie, someone who enjoys impacting social problems using tech. In recent years, I have shifted from consumer devices into supply chain innovation leading to carbon offsetting, which exposes me to various operational, perceptive and implementation challenges.  I come from a farming family first-generation engineer, born around the invention of the internet- in the early 90s I used to hear how repairability was a desired feature in tools around us, and local was the way to go. In today’s hyper-connected time- being in d

What if phones were made like shuttlecocks!

Now evolution is a slow process, and as humans and smartphone users this evolution to 'not drop things' is going to only happen in a million years. It's easier to redesign bodies/smartphones. I shattered two phones in the last two years, two screens I got replaced were expensive and quite a hit on the pocket. Humans drop things. What I don't understand is that the screen is the most sensitive part of the phone yet it shatters easier than feather. The phone has other parts too- an incomprehensibly well made PCB, modem, battery, and the casing . Observing a smartphone physically: Now the parts above with respect to screen are packed in this fashion primarily for three reasons: packing, protection and function. The case's job is to protect, the electronics are for function, and fasteners/glues for packing.  It's pretty clear that current design of smartphone fails pretty badly at protection: one of the most expensive parts, the screen(alumi

Intuitive Gesture Pad for Hindi typing

I happened to stumble across a gesture pad devised by Shekhar Borgaonkar. Needless to say, its one of the most wonderful innovations as per inputting Devnagri(Hindi) script is concerned. Due to its complexity, the Hindi based keyboards used today aren't user friendly at all. A beginner cannot think of using the same for text entry. Interfacing the same to a touchscreen/stylus-input make it intuitive, and hence cut down the learning curve required to type hindi into Computers/cellphones. Exactly as Shekhar says "I think this will benefit India because many people will be able to interact with computers for the first time in their life. " The demo of the concept is downloadable here
