Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If welding is used to connect the light bar with metal wires, then reliable electrical connection is achieved, but the production process becomes complex and time-consuming
Solution Approach 1:
The patent replaces the welding process (thermal/mechanical system) with a mechanical plug-in connection system. The light bar is equipped with plug-in contacts that directly insert into corresponding receptacles on the metal wire support, eliminating the need for welding operations while maintaining reliable electrical connection through direct mechanical and electrical contact.
Solution Approach 2:
The patent introduces a metal wire support structure with plug-in receptacles as an intermediary component. This intermediary enables the light bar to connect to the metal wire without direct welding, by providing a standardized interface that accepts the light bar's plug-in contacts, thereby simplifying the overall connection process.
2Reliability
If welding and positioning of the light bar are performed, then proper electrical circuit formation is achieved, but the production time increases
Solution Approach 1:
The patent incorporates plug-in contacts directly onto the light bar during its manufacturing process, and pre-configures the metal wire support with corresponding receptacles. This preliminary preparation eliminates the need for on-site welding and positioning operations during final assembly, allowing for rapid plug-in connection that significantly reduces production time while ensuring proper electrical circuit formation.
3Strength
If traditional welded structure is used, then strong mechanical strength is achieved, but the waterproof performance deteriorates due to multiple sealing requirements
Solution Approach 1:
The patent employs a waterproof coating or membrane structure on the lamp bulb shell and connection interfaces to provide flexible waterproof sealing. This approach creates a continuous waterproof barrier that accommodates the plug-in connection structure without requiring multiple rigid sealing joints, thereby maintaining both mechanical strength and superior waterproof performance.
