Cylindrical Battery Heating Structure for Uniform Multi-Cell Warming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery heating devices struggle to uniformly heat multiple cylindrical batteries while accommodating them without contact with the sidewalls, and lack flexibility to adapt to different battery diameters and shapes.
Innovation Solution
A battery heating device with a support module comprising a first module with accommodation spaces and openings, and a second module with penetration portions that adjust battery positions, allowing for precise accommodation and heating of cylindrical batteries of varying diameters, using a fixing element to secure the modules and a control module for temperature detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed support structure is used to accommodate cylindrical batteries, then the device structure is simple, but it cannot adapt to different battery diameters and shapes
Solution Approach 1:
The support module is divided into a first module (base structure with accommodation spaces) and a second module (adjustable positioning structure with penetration portions). This segmentation allows the second module to be adjusted for different battery diameters while the first module remains fixed, resolving the contradiction between adaptability and structural simplicity.
Solution Approach 2:
The second module is designed to be adjustable rather than fixed, allowing the penetration portions to be repositioned according to different battery diameters. This dynamic adjustment capability enables the device to adapt to various battery sizes without requiring a completely different support structure for each size.
2Manufacturing precision
If batteries are placed in accommodation spaces with sidewalls, then positioning is simple, but batteries contact sidewalls causing non-uniform heating
Solution Approach 1:
The penetration portions are designed with different diameters corresponding to different battery sizes, allowing each battery to be positioned at the appropriate location within the accommodation space. This local customization of positioning structures ensures that batteries of different sizes can be accommodated without contacting the sidewalls, thereby achieving uniform heating.
3Adaptability or versatility
If a single support module design is used for all battery types, then the device is simple to manufacture, but it cannot accommodate various types of cylindrical batteries
Solution Approach 1:
The first module is designed as a universal base structure that can accommodate multiple battery types, while the second module provides adjustable positioning capabilities. This combination allows a single support module design to serve multiple battery types without requiring completely different structures for each battery type, balancing manufacturability with versatility.
