Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The first connector in conventional battery structures is prone to deformation during the welding process with the first adapter, leading to poor welding and potential open circuits, resulting in battery scrapping.
Innovation Solution
Incorporating a supporting block arranged at the first connector, which matches with the connector's accommodating part, providing additional support and preventing deformation during welding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the first connector is formed by bending thin sheet metal to facilitate welding, then the ease of manufacture is improved, but the mechanical strength deteriorates causing deformation during welding
Solution Approach 1:
The first connector is divided into two parts: a bent thin sheet metal portion for welding and a reinforcement portion with increased thickness for mechanical strength. This segmentation allows each part to fulfill its specific function without compromising the other.
Solution Approach 2:
The reinforcement portion is strategically positioned at the welding area where mechanical strength is most needed. The thickness of the first connector varies locally - thinner at non-welding areas for ease of manufacture, and thicker at the welding area for strength.
2Reliability
If pressure is applied to compress the first adapter and first connector tightly during welding, then the welding quality is improved, but the deformation of the first connector worsens
Solution Approach 1:
The reinforcement portion is designed in advance to compensate for the deformation that would occur during welding. Its increased thickness provides a buffer that prevents excessive deformation when compression pressure is applied during the welding process.
Solution Approach 2:
The thickness parameter of the first connector is changed at the reinforcement portion, creating a local variation that increases rigidity and resistance to deformation during the welding compression process while maintaining overall manufacturability.
