Electromechanical prototype
Kelvin Hot+Cold: turning a temperature-control concept into hardware for discovery.
A reusable handheld temperature-control prototype that packaged cooling and warming, custom electronics, enclosure details, and hands-on testing for customer discovery.
The challenge
Single-use ice packs are limited and unreliable for many urgent situations. Kelvin needed a reusable prototype that could control temperature, stay portable, and prove the product direction before any production decision.
Constraints
- +A reusable product direction rather than a single-use ice pack.
- +Portable controlled cooling and warming in a handheld prototype.
- +Prototype learning before any production decision.
Documented scope
- +Prototype mechanical design and enclosure packaging
- +Collaboration with an electrical engineer on the custom PCB
- +Hands-on assembly, bring-up, and prototype testing
Approach
- +Packaged controlled cooling and warming, custom electronics, and enclosure details into one handheld prototype.
- +Used the custom-PCB collaboration as part of the prototype package.
- +Built, brought up, and tested the physical prototype for customer discovery.
Deliverables
- +Working physical prototype
- +A clearer product package for customer discovery
- +A stronger foundation for product feedback
What remains unverified
This case study does not claim medical suitability, thermal performance, safety validation, certification, manufacturability, or production readiness. Those questions need their own testing, review, and written scope.
