Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional soldering or welding methods are used to connect the circuit board to the battery module, then the electrical connection is strong and reliable, but the process becomes complex and difficult to reset or manipulate
Solution Approach 1:
The connection system is segmented into separate components: a substrate with fastening holes, connection circuit boards with contact pads, and fastening hooks. This allows the electrical connection to be made through simple mechanical insertion rather than permanent soldering or welding, enabling easy reset while maintaining reliability through proper contact design
Solution Approach 2:
The substrate acts as an intermediary component between the battery module and the circuit board. It provides a structured interface with fastening holes that guide the fastening hooks, ensuring proper alignment and contact between the connection circuit boards and the circuit board while simplifying the overall connection process
2Reliability
If the circuit board is permanently fixed to the battery module, then the electrical connection remains stable, but the ability to reset power or perform maintenance becomes difficult
Solution Approach 1:
The connection system transitions from a static permanent connection to a dynamic reversible connection. The fastening hooks can be inserted into and removed from the fastening holes on the substrate, allowing the electrical connection to be easily made or broken as needed for power reset or maintenance while maintaining stability when connected
Solution Approach 2:
The patent replaces traditional mechanical soldering or welding systems with a simpler mechanical fastening system using hooks and holes. This substitution maintains electrical connection stability through proper mechanical engagement while dramatically improving ease of operation for power reset and maintenance activities
