Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If power interface and signal plug ports are welded at the end portion of the light-emitting module, then electrical connection is achieved, but production operation becomes complex and assembling difficulty increases
Solution Approach 1:
The patent extracts the welding operation from the assembly process by using a plug connector system. The power interface and signal plug ports are separated into modular components that connect via plugging rather than welding, eliminating the complex welding step while maintaining reliable electrical connection.
Solution Approach 2:
The patent introduces a plug connector as an intermediary component between the light-emitting module and the control circuit. This mediator provides the electrical connection function without requiring direct welding, simplifying the overall assembly process while ensuring reliable signal and power transmission.
2Reliability
If power interface and signal plug ports are welded at the end portion of the light-emitting module, then electrical connection is achieved, but production cost increases
Solution Approach 1:
The patent removes the costly welding operation from the manufacturing process by adopting a plug connector system. This extraction of the welding step significantly reduces production cost while maintaining the necessary electrical connection reliability through the modular plug design.
3Ease of manufacture
If LED lamp panel is threaded out of the plastic seat, then assembly is simplified, but waterproof sealing becomes challenging
Solution Approach 1:
The patent introduces a waterproof ring as an intermediary sealing element at the interface between the LED lamp panel and the plastic seat. This mediator provides the necessary waterproof sealing while allowing the simplified threaded assembly structure to remain in place, resolving the conflict between easy assembly and effective sealing.
4Device complexity
If conductive modules are plugged into the plug-in slot, then assembling difficulty is reduced, but connection reliability must be maintained
Solution Approach 1:
The patent extracts the welding operation and replaces it with a plug connector system, reducing assembling difficulty while maintaining connection reliability through the designed plug-in mechanism with proper contact alignment and securing features.
