Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If strip lamps are welded to a printed circuit board for electrical connection, then reliable electrical connection is achieved, but the complexity of assembly and replacement increases
Solution Approach 1:
The electrical connection system is segmented into separate components: a power supply unit with connection terminals and strip lamps with corresponding connectors. This segmentation allows the strip lamps to be independently connected and replaced without affecting the entire circuit board, resolving the contradiction between reliable connection and assembly complexity.
Solution Approach 2:
Connection terminals and connectors serve as intermediary elements between the power supply and strip lamps. These intermediaries provide reliable electrical connection through standardized interfaces while enabling easy assembly and replacement, eliminating the need for complex welding operations.
2Reliability
If strip lamps are welded to a printed circuit board, then stable electrical connection is achieved, but the ease of replacing individual strip lamps deteriorates
Solution Approach 1:
The system is divided into replaceable modular units where each strip lamp can be independently disconnected and replaced. The connection terminals and connectors enable this modularity while maintaining stable electrical connection during operation, directly addressing the repairability issue.
Solution Approach 2:
The strip lamps are designed as replaceable consumable components with simple connector interfaces. When a strip lamp fails, it can be quickly replaced by disconnecting its connectors from the power supply terminals, treating the strip lamp as a replaceable unit similar to disposable components, thereby improving ease of repair.
3Reliability
If welding is used to connect strip lamps to the circuit board, then strong electrical connection is achieved, but the ease of manufacture and assembly deteriorates
Solution Approach 1:
Connection terminals and connectors act as intermediary components that provide strong electrical connection without requiring welding. These intermediaries feature standardized interfaces that simplify the manufacturing and assembly processes while maintaining reliable electrical connection between the power supply and strip lamps.
Solution Approach 2:
The welding process (thermal-mechanical system) is replaced with a mechanical connector system. The connectors provide sufficient electrical connection strength through mechanical engagement and contact, eliminating the need for complex welding operations and significantly improving ease of manufacture and assembly.
