Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate circuit boards are used for LEDs and controlling module, then reliability is improved through modular design, but device complexity increases and manufacturing time is extended
Solution Approach 1:
The patent integrates the controlling module and LED mounting onto a single circuit board, eliminating the need for separate circuit boards and reducing assembly steps. This merging approach reduces device complexity and manufacturing time while maintaining functional reliability through unified electrical connections and simplified assembly procedures
2Ease of repair
If separate circuit boards are used for LEDs and controlling module, then ease of repair is improved through modularity, but manufacturing time is extended
Solution Approach 1:
The integrated circuit board design combines controlling module and LED mounting into one unit, reducing the number of assembly operations required during manufacturing. This approach significantly reduces manufacturing time while maintaining repairability through standardized component placements and accessible circuit board design
3Reliability
If predestinated volume of controlling module is used, then reliability is maintained through standardized design, but volume of housing cannot be reduced
Solution Approach 1:
The patent integrates the controlling module directly onto the LED circuit board, eliminating the need for a separate predestinated module housing. This integration allows for optimized space utilization and significant reduction in overall housing volume while maintaining the functional integrity and reliability of the controlling circuitry
Solution Approach 2:
The controlling module components are arranged in a compact layout on the circuit board plane, utilizing two-dimensional space optimization. This dimensional arrangement allows for reduced overall volume by distributing components across the circuit board surface rather than requiring three-dimensional module stacking
