Heatable Garment Battery Integration and Heat Reservoir
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing heatable wear devices, such as gloves and scarves, face challenges in assembly due to the need to keep lithium-ion or solid-state batteries isolated from heating plates, resulting in excessive space, complex assembly, and diffused heat sources.
Innovation Solution
A heatable wear device design that closely integrates an explosion-proof battery with a heating layer and a high-specific-heat covering layer, using a Solid State Battery with a flexible printed circuit and metal wire heating elements, where the covering layer acts as a heat reservoir to absorb and radiate heat, allowing for a compact assembly and reduced power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the lithium-ion battery or solid state battery is kept at a safe distance away from the heating plate, then the battery can be protected properly, but the assembled space becomes excessive and the heat sources become diffused
Solution Approach 1:
The patent introduces a heat-resistant substrate as an intermediary component between the battery and heating plate. This substrate can withstand high temperatures and allows the battery to be positioned closer to the heating plate without compromising safety, thereby reducing assembled space while maintaining battery protection
Solution Approach 2:
The patent integrates the battery, heating plate, and heat-resistant substrate into a unified heating structure assembly. By merging these components into a compact integrated unit, the overall assembled space is reduced while maintaining the functional separation and protection between the battery and heating elements
2Reliability
If the lithium-ion battery or solid state battery is kept at a safe distance away from the heating plate, then the battery can be protected properly, but the assembly steps become complicated
Solution Approach 1:
The patent combines the battery, heating plate, and heat-resistant substrate into a pre-assembled integrated heating structure. This merging reduces the number of separate assembly steps required, as the components are already positioned and secured relative to each other in the final product
3Duration of action of moving object
If the covering layer with high specific heat is used as a heat reservoir, then the operation time can be extended and power consumption reduced, but the device complexity increases
Solution Approach 1:
The covering layer is designed to serve multiple functions: it provides thermal insulation, acts as a heat reservoir due to its high specific heat capacity, and contributes to the overall structural integrity of the heating assembly. This multi-functionality extends operation time without proportionally increasing device complexity
