Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the number of lamp beads increases in existing parallel-connected lamp strings, then the lighting coverage is improved, but the required current increases leading to higher wire requirements and cost
Solution Approach 1:
The patent divides the lamp string into multiple independent series-connected modules, each module containing a specific number of lamp beads (e.g., 6 LEDs per module). This segmentation allows the total number of lamp beads to be increased by adding more modules in series, thereby increasing lighting coverage without proportionally increasing the current requirement, as each module operates at its own optimized current level.
Solution Approach 2:
The patent changes the operating voltage parameter from low voltage (5V-12V parallel) to high voltage (series connection at higher voltage levels). By operating at higher voltage with lower current, the system can support more lamp beads without requiring thicker wires or higher current-capacity power supplies, thus reducing material costs while maintaining lighting coverage.
2Quantity of substance
If the number of lamp beads increases in existing parallel-connected lamp strings, then the lighting coverage is improved, but the wire requirements and cost increase
Solution Approach 1:
The patent segments the lamp string into standardized modules that can be series-connected. Each module is designed with integrated wiring structures (such as PCB traces or printed circuits) that simplify inter-module connections. This modular segmentation reduces the overall wire complexity compared to custom wiring required for individual parallel-connected LEDs, as the modular design provides standardized connection interfaces.
Solution Approach 2:
The patent replaces traditional mechanical wire connections with printed circuit board (PCB) traces or integrated circuit pathways for electrical connections between LED modules. This substitution eliminates the need for extensive manual wire routing and soldering, thereby reducing wire requirements and assembly complexity while supporting a higher number of lamp beads.
3Ease of operation
If existing lamp strings are connected in parallel, then the installation is simple, but series connection is not possible limiting flexibility
Solution Approach 1:
The patent creates modular lamp string units that can be connected in series through standardized interfaces. Each module contains complete circuitry and connection terminals, allowing multiple modules to be easily linked in series configuration. This modular segmentation maintains installation simplicity while enabling series connection flexibility, as the modules can be daisy-chained using standardized connectors without complex wiring.
Solution Approach 2:
The patent designs the lamp string modules with universal connection interfaces that support both series and parallel connection configurations. The same modular unit can be adapted to different voltage requirements and connection topologies, providing versatility in installation options while maintaining ease of operation. This multi-functionality allows the system to be configured for series connection when higher voltage and lower current are desired, or parallel connection when simpler installation is prioritized.
