Design a shower for the blind.

Clarifying Questions:

  • Will this shower be in a home?

  • I am assuming the bathroom is available with proper plumbing and electricity?

  • Will this be for all ages?

  • Will this be an entire shower unit or just a specific function or add-on?

  • Does it need to work for blind people only?

A shower has a simple function of providing water and at a certain temperature. I am making the assumption, a bling person can find the bathroom, take off their clothes, locate the shower, turn on the water, test the temperature of the water, locate the shampoo and soap, wash and put on their clothes. So, why should we design a shower for blind people?

Problem Statement: Blind people can not see or are visually impaired. They can use sound and touch. They are able to move around.

The goal would be to design a shower that is easy to use, safe, and innovative that blind people will love.

Who are we solving for?

Segments:

  • Caretaker

    • Someone who goes to the blind person’s house and helps them

    • It could be a family member who lives in the same house

  • The person taking the shower

    • Could be living alone and in an apartment or house.

    • Owning or renting (can not remodel the bathroom but can install add-ons)

  • Faculty: Gym, Hospital

    • Public showers and a shower is need for people with special needs

Why:

I would focus on solving for the blind person who is the person taking the shower

  • Our goal is to design a shower for the blind

  • My assumption is they will widely adopt it compared to other segments

  • If we can provide a good experience to the blind, then we will solve the problem for other segments such as caretakers and facilities.

What are their Problems / Needs:

  • 1.) Supplies: How much shampoo is left? Is this Shampoo, Body Wash or Conditioners?

    • They can feel the weight to estimate if it’s below average.

    • They can remember the location or smell of supplies

  • 2.) Washing Process: If you are using wash clothes you don’t know if you got enough soap on it.

    • They can use their hands instead of a washcloth

  • 3.) Safety:

    • Getting in and out of the shower

      • Any moisture that can make you slip and fall

      • There may not be any resources for getting up after a fall may not be

When I think of showers today and the functionality, I would make the assumption that showers are easy enough for a blind person to operate and complete. Today was functions have simple buttons to click and have sound activation to change settings. What I don’t see is anything that provides safety precautions. I am doing a quick gap analysis and believe that blind people are underserved in safety features. The other problems mentioned have workarounds. They can be solved in a different way, therefore, won’t provide meaningful value.

Solutions: solving for safety

  • Moisture Sensor

    • Recognition of moisture to warn a person to be careful and approx location.

    • Automatically turn on the shower fan or open the window

  • Get Help

    • Voice-activated call to 911

    • Call caretaker, friend or family member

    • Integration with Amazon to buy something

  • Anchors

    • Grab Bars: Prevent from falling (holding on) or help to get up

    • Rugs or mats could move to cause you to slip

Moisture could cause a person to slip and fall, which may require them to seek help. But I am assuming you can feel moisture with your hands or feet.

Getting help could have multiple use cases, such as remembering/asking to order more supplies, seeking help, or forgetting something such as your towel.

Anchors can prevent you from falling and also in some cases can help you recover.

I will prioritize solutions based on a few parameters: is it a common use case, cost of development, and dependencies.

Solutions

Common Use Case

Cost of Development

Dependencies

Moisture Sensor

If you the only person living there, it’s not common to have moisture.

High: design, program, and manufacturer

Install, Power

Get Help

Could be used for calling, ordering, and storing notes.

Medium: You can use pre-build modules and just program the software with basic functions.

Wifi or SIM card, Install and Power

Anchors

You can reuse for different products: toilet, mats/rugs, walls.

Low Cost to manufacture and buy for consumers.

Install

Comment: I struggled to put together a final design or solution that focuses on safety. I am not sure if my final solution should be about adding bars in shower and bathroom. Anyone one have feedback or suggestions on how to close this solution?

Let me take a stab at it.

Clarify:  Do you mean design the entire shower or just the shower head

Interviewer:  Upto you.  You pick!

User Group or Persona: 

Okay – Let’s define the user groups or the persona

  1. One who is blind but physically able to taek the shower by themselves.
  2. One who is blind but depends on care taker

I’ll pick the 1st user group as the goal of this product is to make them self sustainable.

 

Need / Pain points: 

  1. Getting to the shower (Need for Grab bar?)
  2. Idenfity where the shampoo/ body wash is and distinguish between body wash, shampoo and conditioner
    1. Difficult to know in advance how much more is left
  3. Set the right temparature

I’ll focus on 2 & 3 as the first one is available in many homes already by default.

 

List of Solution:

  1. Refillable bottle that makes different sound
    1. Helps distinguish between shampoo and conditioner etc
  2. Shower unit with voice assitant GA/ Alexa
    1. Can set the right temparature via voice
    2. Easy start and stop
    3. Adjust pressure
  3. Shower unit with Shampoo dispenser and has GA / Alexa integration

Prioritize or Evaluate solution

  1. Refillable bottle is an easy solution but doesn’t let the user know in advance how much more is left.  Also, if the bottle falls of by mistake, it is an additional pain point to find out where the bottle is
  2. Shower Unit with Voice assistant GA/Alexa along with Shampoo dispenser seems like it solves multiple pain points and doesn’t introduce anything new

Final Solution (Story telling):  I would focus on shower unit with voice assistant with shampoo dispenser because it solves multiple paint points and most shower heads are easily replacable.  This will make sure that user adoption is easy.   The showerhead  comes with a dispenser bar below (I tried uploading a mock but upload didn’t work) – So imagine a Tennis Racket with a bent handle style design where the below dispenser bar rests on the wall making sure it doesn’t introduce any hazard.   I’ll also put a sensor  at the 30% level of the dispenser – Liquid sensors are very cheap so this should not increase the development cost significantly and alerts the user ahead of time.  The purchasing is also easily done via Google or Alexa checkout.

 

Summary:  The goal of this product is to make sure that the blind person can take the shower without making a lot of movement.  The voice assistant helps them set the temparature, pressure and to start/stop the shower.  This will also help them get the soap / shampoo/ conditioner without having to worry about choosing the right bottle.  Overall, the product can be easily installed without any additional plumbing work which makes it easy to adopt and reduces the uptake cost for the user.
