Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If LED modules are designed according to various power consumptions, then power consumption is optimized, but device complexity and manufacturing cost increase
Solution Approach 1:
The LED lighting device is divided into modular components: LED modules that can be independently configured, a separate heat radiating member, side frames, and a support frame. This segmentation allows flexible assembly of LED modules according to power consumption requirements without redesigning the entire system, resolving the contradiction between power optimization and manufacturing complexity.
Solution Approach 2:
The heat radiating member serves multiple functions: it radiates heat from LED modules, provides structural support, and acts as a mounting platform. The modular design allows the same basic structure to accommodate different power consumption levels by simply changing the number of LED modules, achieving universality across different power requirements.
2Illumination intensity
If conventional LED street lamps are designed for high power consumption, then illumination intensity is sufficient, but size and weight increase
Solution Approach 1:
The device separates the weight burden by dividing components into modular LED modules mounted on a heat radiating member, which is supported by side frames and a support frame. This segmentation allows the illumination system to achieve high light output while distributing and reducing the overall weight compared to conventional integrated designs.
3Illumination intensity
If conventional LED street lamps are designed for high power consumption, then illumination intensity is sufficient, but manufacturing cost increases
Solution Approach 1:
The modular architecture with standardized heat radiating members, side frames, and support frames enables cost-effective manufacturing. LED modules can be produced independently and assembled in different quantities to meet various illumination requirements, reducing overall manufacturing cost compared to custom-designed high-power systems.
4Strength
If conventional LED street lamps are designed with integrated structure, then structural strength is sufficient, but heat radiation performance is poor
Solution Approach 1:
The device separates the heat radiating function from the structural support function. The heat radiating member with its specific surface structure is dedicated to heat dissipation, while side frames and support frames provide structural strength. This segmentation allows optimization of both heat radiation and structural strength independently, resolving the contradiction between integrated structural strength and heat radiation performance.
5Reliability
If conventional LED street lamps use sealed structure, then waterproof effect is provided, but heat radiation is blocked
Solution Approach 1:
The device separates the waterproof function from the heat radiation function. The heat radiating member has an exposed surface structure optimized for heat dissipation, while separate sealing components (gaskets, seals on LED modules and connections) provide waterproof protection. This segmentation allows the heat radiating surface to remain open and effective while waterproofing is provided by dedicated sealing elements at interfaces and connections.
