Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual soldering of metal jumpers is used to connect multiple FPCB lamp boards, then the electrical circuit can be established, but production efficiency is reduced and safety risks increase
Solution Approach 1:
The patent merges multiple separate connection components (metal jumpers and metal leads) into a single integrated conductive connection plate. This connection plate is pre-formed with conductive patterns that establish electrical circuits directly on the FPCB lamp board, eliminating the need for manual soldering of separate jumpers and leads, thereby improving production efficiency while maintaining reliable electrical connections
Solution Approach 2:
The conductive connection plate is pre-formed with the necessary conductive patterns and connection points before being integrated into the FPCB lamp board. This preliminary preparation of the connection structure allows for automated assembly processes rather than manual soldering during final assembly, significantly boosting productivity while ensuring reliable electrical circuit establishment
2Reliability
If multiple metal jumpers and metal leads are used to connect FPCB lamp boards, then the electrical circuit can be established, but the structure becomes complex
Solution Approach 1:
The patent combines multiple separate metal connection components (jumpers and leads) into a single integrated conductive connection plate with pre-designed conductive patterns. This consolidation reduces the number of separate parts from multiple jumpers and leads to just one connection plate, significantly simplifying the overall structure while maintaining reliable electrical circuit connections
Solution Approach 2:
The conductive connection plate serves multiple functions simultaneously: it provides electrical connection points, establishes conductive pathways, and acts as a structural element for mounting LED light sources. This multi-functionality eliminates the need for separate specialized components, reducing structural complexity while ensuring reliable electrical connections
3Reliability
If manual soldering is used to connect metal jumpers, then the electrical circuit can be established, but safety risks increase
Solution Approach 1:
The patent integrates the electrical connection function into a pre-formed conductive connection plate that is assembled as a single unit with the FPCB lamp board. This eliminates the manual soldering process entirely, removing the safety risks associated with hot soldering irons and manual operations, while still establishing reliable electrical circuits through the integrated conductive patterns
Solution Approach 2:
The patent replaces the thermal-mechanical soldering process with a mechanical assembly process where the conductive connection plate is mounted and connected through non-thermal means. This substitution eliminates exposure to hot soldering irons and manual soldering hazards, reducing safety risks while maintaining reliable electrical circuit connections through the integrated conductive structure
4Reliability
If strip-shaped FPCB lamp boards are used with manual soldering, then the LED light strip can be formed, but automated production cannot be achieved
Solution Approach 1:
The conductive connection plate is pre-formed with all necessary conductive patterns, connection points, and mounting features before assembly. This preliminary preparation allows the entire FPCB lamp board with integrated connection plate to be assembled using automated pick-and-place or other automated assembly equipment, enabling automated production while ensuring reliable LED light strip formation
Solution Approach 2:
The patent merges the conductive connection plate with the FPCB lamp board into a single integrated assembly that can be handled and assembled as one unit by automated equipment. This integration eliminates the need for manual soldering operations during automated assembly, enabling fully automated production of LED light strips while maintaining reliable electrical connections and proper LED mounting
