Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery pressurizing devices face challenges in achieving consistent flatness and preventing damage during the pressurization process due to uneven battery surfaces, as they often rely on sliding friction and require multiple jigs and fixtures for different battery types, leading to high capital investment and replacement costs.
Innovation Solution
A battery pressurizing device with a rotatable pressurizing mechanism featuring rollers with arc-shaped surfaces and elastic insulating materials, allowing for line or point contact and reducing friction to accommodate varying surface protrusions, while adjustable pressurizing assemblies and mechanisms ensure consistent pressure and compatibility with different battery sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a pressurizing component applies pressure in one direction to compress the battery, then the battery achieves the specified size, but the surfaces of the battery in other directions become deformed and flatness deteriorates
Solution Approach 1:
The pressurizing component is divided into multiple independent pressurizing units that can apply pressure in different directions simultaneously. Each unit targets specific surfaces of the battery, allowing multi-directional compression to achieve both size reduction and surface flatness without the deformation problems of single-direction pressing.
Solution Approach 2:
The pressurizing device is designed with adjustable and interchangeable pressurizing units that can accommodate different battery types and pressing requirements. The same device structure can perform single-direction or multi-directional pressing by configuring different combinations of pressurizing units, making it universally applicable to various battery pressurizing scenarios.
2Adaptability or versatility
If a universal pressurizing device is used for different battery types, then device versatility is improved, but the capital investment and replacement costs increase due to needing multiple jigs and fixtures
Solution Approach 1:
The pressurizing device employs a modular design where pressurizing units can be configured and reconfigured for different battery types. The same basic device structure serves multiple functions by adjusting the arrangement and number of pressurizing units, eliminating the need for completely different jigs and fixtures for each battery type.
Solution Approach 2:
The device incorporates adjustable and movable components that can be repositioned according to different battery dimensions and pressing requirements. This dynamic configurability allows a single device to adapt to various battery types without requiring multiple fixed fixtures, reducing both capital investment and replacement costs.
