Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate connection structure and wiring structure are used to connect battery cells and collect measurement signals, then electrical connection and signal collection functions are achieved, but assembly process complexity increases and productivity decreases
Solution Approach 1:
The patent combines the connection structure and wiring structure into an integrated circuit board assembly. The circuit board simultaneously serves as both the connection structure for electrically connecting battery cells and the wiring structure for collecting measurement signals, eliminating the need for separate assembly processes and reducing overall system complexity.
Solution Approach 2:
The circuit board is designed to perform multiple functions: it provides electrical connection between battery cells through conductive patterns, collects measurement signals through integrated wiring, and serves as a structural support element. This multi-functional design reduces the number of separate components needed in the battery pack.
2Reliability
If individual wire connections are used to collect measurement signals from each battery cell, then signal collection is achieved, but assembly time increases and productivity decreases
Solution Approach 1:
The wiring structure for signal collection is merged with the connection structure into a single integrated circuit board assembly. This allows measurement signals from multiple battery cells to be collected simultaneously through pre-integrated wiring paths, eliminating the need for sequential individual wire connections and significantly reducing assembly time.
3Reliability
If multiple separate components are used for connection and wiring, then functional requirements are met, but manufacturing complexity increases
Solution Approach 1:
The patent integrates the connection structure and wiring structure into a single circuit board assembly that can be manufactured as one unified component. This reduces the number of separate manufacturing steps, minimizes the variety of components that need to be produced and managed, and simplifies quality control processes.
Solution Approach 2:
The circuit board is designed with modular conductive patterns and wiring paths that can be independently designed and manufactured, then assembled into the final integrated structure. This segmentation approach allows for standardized manufacturing processes while achieving the complex integrated functionality.
