Design for the Other 90%: Bridging Gaps with Inclusive Design

 

In a world where access to basic necessities remains a luxury for many, the concept of "Design for the Other 90%" emerges as a beacon of hope.  This movement, spearheaded by designers, engineers, and social entrepreneurs, aims to bridge the gap by creating affordable and practical solutions for the vast majority of the global population living in poverty.  At its core, "Design for the Other 90%" embodies the ethos of inclusive design, striving to empower underserved communities and improve their quality of life.


Origins and Ideals

The genesis of "Design for the Other 90%" can be traced back to Cynthia E. Smith's seminal book of the same name.  Through her work, Smith sheds light on the stark reality that approximately 90% of the world's population lacks access to essential products and services.  These range from clean water and sanitation facilities to adequate housing and healthcare.  The movement challenges traditional design paradigms, urging practitioners to shift their focus from serving the affluent minority to addressing the needs of the marginalized majority.

Cooper Hewitt Exhibition: Showcasing Innovation

One of the pivotal moments in the "Design for the Other 90%" movement was the exhibition hosted by the Cooper Hewitt, Smithsonian Design Museum.  Titled "Design for the Other 90%“, the showcase featured over 30 innovative projects from around the globe.  These projects exemplified the principles of inclusive design, offering solutions to pressing challenges faced by underserved communities.  From low-cost medical devices to sustainable agricultural tools, each exhibit underscored the transformative power of design in uplifting lives.

Documentary Series: Designing for Change

Complementing the exhibition is the documentary series "Design with the Other 90%.”  Through compelling narratives and real-life examples, the series delves into the transformative potential of design in developing cities.  By highlighting the stories of grassroots innovators and community-led initiatives, the documentaries inspire viewers to rethink conventional approaches to design and embrace a more inclusive and equitable ethos.

Looking Ahead: A Call to Action

As we navigate an increasingly interconnected world, the imperative to design for the other 90% has never been more pressing.  While progress has been made, significant challenges persist.  Climate change, urbanization, and economic disparities continue to exacerbate inequalities, disproportionately affecting the most vulnerable.  However, amidst these challenges lies an opportunity for collaboration and innovation.

By harnessing the power of design, we can unlock solutions that transcend borders and transform lives.  Whether it's leveraging renewable energy technologies to provide clean power to off-grid communities or developing affordable housing solutions resilient to local environmental conditions, the possibilities are endless.  However, it requires a collective effort—one that transcends disciplines and embraces diversity of thought.

In conclusion, "Design for the Other 90%" serves as a powerful reminder of the transformative potential of design in building a more inclusive and sustainable future.  Through empathy, creativity, and collaboration, we can bridge the gap and ensure that no one is left behind.

On a personal note, I came across the Cooper Exhibit and was greatly impressed.  About that same time, there was an issue of Time Magazine, from what I remember, that was all on “water” – the entire issue covered the world and how precious water is to many people on a daily/hourly basis.  I’m so lucky to live in a place where water is prevalent, yet the magazine changed my behavior to trying to save water on a personal basis and to treat it as precious, too.

Furthermore, I was nearing retirement and I thought I’d use my technical and research abilities to make some blog articles and here they are below.  I hope you and/or others find them useful.

Tom's Personal Clinic

Here's what "Tom's Personal Clinic" looks like so far. See my Do It Yourself Doctoring Blog for the progress reports.

Let me know if you want to know more or would like to see this setup in person! Feel free to pass this along to others who might be interested.


So far, here's what I can do....

Urine/Saliva pH,

10 panel urine test,

Average Blood Pressure,

Phonocardiograph, - Click here for "how to make"

Endoscope/Otoscope, etc. - Click here for more "how to" information

* Internet access to Symptom Checkers and other Health Information.

* Ability to send my test results to my Healthcare Professional, or anyone else, if I want to - Telemedicine.


All this was done for under $500, including $250 for a used computer.

Click here to see the report I took to the doctor. My doctor was impressed!

Future activities include additional DIY tests, "Super Symptom Checker", Telemedicine, and Interfacing with the Doctor Within. Good Luck on your own DIY Healthcare Journey!

That's about all for now. As background, the site "Design for the Other 90%" said to "GET INVOLVED", so I did. I plan to continue posting these LOW-COST DESIGN TOPICS on my Blog for a while yet. Let me know if you have a topic you would like covered. I'm open to suggestions on improving my blog format, too. Please e-mail me directly.. I hope you find this helpful.

Electronic Stethoscope and Analyzer for under $5.00




Hello All - This posting looks at designing "Low-Cost Electronic Stethoscopes – Heart/Lung Sound Analyzers."



First off, here's something I made for under $5.00. Essentially, I modified a pre-natal heartbeat monitor with a standard stethoscope head, then fed the results into an open-source heart/lung analysis software program.




Below are instructions and see photo album at http://picasaweb.google.com/tgideas/20090716#


1. Find a prenatal heart monitor. I bought mine at a charity shop for $3.00.

2. I found it works better to have an external standard stethoscope head attached to the monitor. Use a plumbing gasket and flexible tubing. Glue the gasket into the monitor head. Push the tubing into the gasket. Connect the other end of the tubing to a standard stethoscope head. I suppose you could use a small funnel if you can't find a stethoscope head.

3. On my monitor, I force the LISTEN button permanently down with a soda bottle cap and duct-tape. I then only use the ON/OFF volume control to turn the monitor on/off and adjust volume.

4. Connect the output of the monitor to the input of a laptop.

6. You're done! I plan to take a printout of my heartbeat and lung sounds with me on my next physical exam, along with normal heart and lung sound printouts too.

7. Long term, I plan to send these sounds and analysis to my doctor (telemedicine).
If you don't like what I did – here's a few others...plus some other links you might find useful.
http://nielsolson.us/Haversian/2007/12/stethophone.php
If you still don't see what you're looking for, check out these patents. Please remember that newer patents are probably not expired, and therefore active. Patents that have expired due to age (generally more than 20 years old from the filing date) are free to use by anyone. Please note that just because something is patented or written, it might not work all that well or might not be safe in today's standards. Use your own judgment, or seek help, to stay safe and out of trouble.

You could ask for help from an Engineering School. Find schools at All Engineering Schools.

So what can you do with all this information? Here's some suggestions.

+ You could make and sell the device described in the expired patent. Please note that just because something is patented or written, it might not work all that well or might not be safe in today's standards. Use your own judgment, or seek help, to stay safe and out of trouble.

+ You could "translate" the expired patent into easy-to-understand instructions for others to make the device. These instructions could use easy-to-find materials, like trees, plants, rocks, people, scrap materials, etc.

+ You could recruit the inventors or authors to help you, since they are experts in their field. Some of the inventors of older patents might be retired now and might be looking for something to do.

+ Existing manufacturers could use this information to make their already fine products even better, more efficient, or less expensive.

+ Build on the work of others. Maybe, use patent images instead of starting with a blank sheet of paper. Computer model other's designs and make the designs better or cheaper or simpler. You don't have to "reinvent the wheel" . Design around active patents.

+ You could use the information to brainstorm new ideas.
