Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current dual-voltage batteries have complex construction and expensive assembly due to spatial integration of battery electronic systems and cell blocks, making preassembly and component replacement difficult.
Innovation Solution
The battery electronic system and battery cell blocks are designed as separate units, allowing for preassembly and functional testing of each unit before final assembly, with power interfaces for tool-free connection and a common circuit carrier for simplified assembly and accessibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the battery electronic system and battery cell blocks are spatially integrated, then functional integration is achieved, but construction complexity increases and assembly becomes expensive
Solution Approach 1:
The patent divides the battery system into separate modular units: a battery cell unit containing battery cells and a battery electronic system unit containing the electronic system. These units are spatially separated but functionally integrated through connection arrangements that enable electrical connection. This segmentation reduces construction complexity while maintaining functional integration, allowing independent assembly and testing of each unit before final assembly.
2Adaptability or versatility
If the battery electronic system and battery cell blocks are spatially integrated, then functional integration is achieved, but preassembly and function testing become difficult
Solution Approach 1:
By separating the battery system into independent battery cell unit and battery electronic system unit, each unit can be preassembled and functionally tested separately before final assembly. The connection arrangements are designed to facilitate this modular assembly process, enabling quality control and defect detection at intermediate stages.
Solution Approach 2:
The patent enables preliminary assembly and function testing of the battery electronic system unit and battery cell unit separately before final assembly. This preliminary action allows defects to be detected early, and components to be tested independently, improving manufacturing quality control and reducing assembly costs.
3Adaptability or versatility
If the battery electronic system and battery cell blocks are spatially integrated, then functional integration is achieved, but component replacement becomes difficult
Solution Approach 1:
The modular segmentation into separate battery cell unit and battery electronic system unit enables easy replacement of defective components. Each unit can be independently removed and replaced without disassembling the entire battery system, significantly improving maintenance and repair ease while maintaining functional integration through the connection arrangements.
