Project Overview

A wearable heat distribution circuit

About

A Soft Thermal Circuit (STC) is an adaptable system for garments, which isolates the heat expelled by the user's body and heating devices, and then distributes it strategically.

Challenge

Design a thermal insulation system with an integrated net of strategic and gradual heat distribution, which could be used to create different garments and other soft products such as furniture.

Discover

Initial research focused on better understanding of heated garments, as well as measuring and observing their effect when exposed to heat.

Observation

Software simulations were made and thermographic images of running heated garments were evaluated to identify potential weaknesses or needs of existing products, and determine how the STC could improve them.

Key Takeaways
01

Thermal sensation varies in the body.

02

Major heated garments distribute heat only to the most sensitive areas of the body.

03

Most heating devices in garments waste heat by distributing it to the outside.

04

Heated garments may limit the user's mobility.

05

Garments with electric heating devices use large batteries.

Define

Conclusions were synthesized to identify issues, opportunities, and features that the STC could focus on and improve upon.

Concept model

It was now necessary to find a conceptual starting point that would allow us to understand the functional and constructive logic of different thermal systems and define new design considerations.

Distribution
  • External coating to prevent heat convection
  • Internal air cells delays heat convection
  • External coating reflects and distributes thermal radiation
Isolation
  • Internal structure allows thermal radiation distribution
  • Internal coating reflects and distributes thermal radiation
  • ‘Windows’ in both coatings allow to distribute thermal radiation

Ideate

During the process I developed sketches, prototypes, 3D models, software simulations and multiple tests to design a system that offered the expected effects.

Sketches

I made multiple sketches and schematics to capture initial thoughts and generate new ideas.

Solution

The STC is a modular thermal configuration made up of soft materials, with specific physical properties to isolate, optimize and control the distribution of heat in specific areas of the human body. The project received an honorable mention in the National Design Award in 2019.

Thesis

The research process required multiple rounds of ideation, prototyping and testing that I documented in an extensive document; my graduation thesis in industrial design.

Renders

The jacket of the future

To present the technology to the jury of my professional industrial design qualification and a design competition, I created graphic representations (renders) of the technology implemented in a jacket.

The project received an honorable mention in the National Design Award in 2019.
