Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery heating devices struggle to uniformly heat multiple cylindrical batteries while accommodating them without contact with 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 thermal insulation material to maintain heat.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed support structure is used to accommodate cylindrical batteries, then the structure is simple and easy to manufacture, 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 relative to the first module, enabling dynamic reconfiguration of the support structure to accommodate different battery diameters and shapes. This dynamic capability provides adaptability without requiring a completely complex redesign for each battery type.
2Productivity
If heating elements are placed close to batteries for efficient heating, then heating efficiency is improved, but temperature uniformity across multiple batteries becomes difficult to control
Solution Approach 1:
The heating element is designed with varying heating zones or intensities across its surface, allowing different regions to provide appropriate heat levels for batteries in different positions. This local quality adjustment ensures both high heating efficiency and uniform temperature distribution across multiple batteries with different thermal characteristics.
3Manufacturing precision
If batteries are positioned to not contact sidewalls for uniform heating, then heating uniformity is improved, but positioning precision becomes more difficult to achieve
Solution Approach 1:
The second module acts as an intermediary positioning structure between the battery and the first module. It includes penetration portions that precisely position batteries without direct contact with sidewalls, ensuring both heating uniformity and easy positioning. The intermediary structure simplifies the positioning operation while maintaining the required precision.
