NXT Strainer 

What Is NXT Strainer?

An arm pillow that is meant for students to nap comfortably at school.


NXT Strainer was done for my Medical Devices university class. It is designed to replace the kidney stone strainer kit that current patients use. This product considers the before and during of the straining process.

The Problem

How might we reduce the hassle of catching arbitrary kidney stones?
Current kidney stone strainers consist of 3 products that users must be cautious about whenever they urinate to take the stone to the doctor for analysis.
Statistics Of The Problem
  • More than half a million people go to emergency rooms because of kidney stones.
  • It is estimated that in 1 in every 10 people will have a kidney stone in their life.
  • Both male and females can get kidney stones.

The Solution

An arm pillow that raises the user's head to nap comfortably.
NXT Strainer is designed to be forgotten in the toilet yet points of interaction are clean.
When patients have the urge to urinate, they won't have to think about taking their strainer kit out like before. 

The Research

This research consists of information regarding participants, market research, and design exploration.

Contextual Observations

I visited the library and witnessed students napping either:
  • on their backpack or jacket while laying down on the floor.
  • in the cross arm position with their head on their arms or a jacket.


Recruited diverse university students from multiple majors with heavy course work that they frequently pull late nights at school. 

Interview Style

1 on 1 interviews in-person
Observed verbal and physical behaviors.

Persona - Marc Jensen

Marc, a 27-year-old software engineer with a penchant for processed snacks and meat, went to the doctor for right-sided pain and was diagnosed with a kidney stone. The doctor prescribed a water diet and provided a 3-piece kit. At home, he often rushes to the bathroom to urinate but forgets to use the kit in his haste.
"The 3 piece kit is not designed for human bladders."
"I don't plan my bathroom visits."
About Him
  • His diet consists of processed, heavy foods and drinks.
  • Lack of exercise
