Handheld Spirometer with Multi-Sensor Hubs

Background

Oval.bio is a start-up based in Austin, Texas. The company focuses on developing open-source wellness devices.

Their team has built a functional prototype as a proven concept (see the 1st image). Because it's not a commonly understood device, they want to ensure regular users can interact with such a device without discomfort, confusion, or frustration. So Mike, the founder, came to me for assistance and partnership.

Scope of work

1,  Understanding the users’ needs, preferences, and behavior when using such devices, and designing our product to maximize users’ experience and ensure effective data collection
2,  Designing a modular system to allow users to switch and expand its function quickly without compromising its portable size
3,  Finding a suitable manufacturing in either the USA or Taiwan (pending)
4,  Oversee the production process (pending)

Process

01 - Define

-  Key components identified; general element size range discussed; overall functions and target users defined
-  Key features: handheld and portable; optional add-on sensors; possible modular configuration; “right-to-repair” design principle
-  Market research; Usability study (initial user testing with client’s prototype)
-  Test data collected and analyzed

02 - Explore

-  Stainless steel with black plastic accent
-  Maximized stainless steel on the appearance, followed the brand language, but still kept the cost reasonable  

03 - Create

-  Stainless steel with black plastic accent
-  Maximized stainless steel on the appearance, followed the brand language, but still kept the cost reasonable  

04 - Refine

-  Stainless steel with black plastic accent
-  Maximized stainless steel on the appearance, followed the brand language, but still kept the cost reasonable  

05 - Deliver (pending)

-  PCB is currently under development
