Deformable Heater and Elastic Member for Power Storage Module
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional power storage devices with heaters struggle to effectively increase the temperature of the power storage module due to gaps formed between the heater and the module, especially when the module bends under its own weight, leading to inefficient heat transfer.
Innovation Solution
A power storage device design featuring a deformable heater and an elastic member that presses the heater against the power storage module, ensuring contact and minimizing gaps, along with a placement stand and accommodation case configuration to optimize heat transfer and retention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the heater module is spaced from the power storage module, then the heater module is fixed securely, but heat transfer efficiency deteriorates
Solution Approach 1:
An elastic member is introduced as an intermediary between the heater and the power storage module. This elastic member deforms to follow the contour of the power storage module surface, ensuring continuous contact and effective heat transfer while maintaining secure fixation of the heater module.
2Loss of energy
If the heater module is brought into contact with the power storage module, then heat transfer efficiency improves, but the power storage module may bend and deform under its own weight
Solution Approach 1:
The elastic member functions as a flexible element that adapts to the power storage module's surface contour. This flexibility allows the heater to maintain contact for heat transfer while the elastic member's compliance prevents rigid constraints that would cause deformation of the power storage module under its own weight.
3Reliability
If a rigid heater mounting structure is used, then the heater is securely fixed, but gaps form when the power storage module bends
Solution Approach 1:
The elastic member provides dynamic adaptability to the mounting structure. As the power storage module bends or deforms under its own weight, the elastic member deforms accordingly to maintain continuous contact between the heater and the module surface, preventing gap formation while securing the heater firmly.
