Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If conventional LED lamps use circuit boards for mounting LED elements, then the structure is simple and manufacturing is easy, but heat dissipation is inefficient causing damage to LED elements
Solution Approach 1:
The patent extracts the LED elements from the conventional circuit board mounting structure and relocates them to be directly mounted on the heat dissipation fins of the holder. This separation of the LED elements from the non-thermal-conductive circuit boards allows heat to be efficiently conducted away from the LEDs through the metal holder fins, solving the heat dissipation problem while maintaining structural simplicity
Solution Approach 2:
The patent introduces the holder with heat dissipation fins as an intermediary structure between the LED elements and the ambient air. The holder serves as a thermal mediator that conducts heat from the LED elements through its fins to the surrounding air, enabling efficient heat transfer without requiring complex cooling systems
2Illumination intensity
If conventional LED lamps illuminate in limited directions, then the structure is simplified, but omnidirectional illumination cannot be achieved
Solution Approach 1:
The patent transitions from planar illumination (in a single plane) to three-dimensional omnidirectional illumination by arranging LED elements on vertical sides and adding top-end LED elements. This dimensional expansion allows light to be emitted in multiple directions simultaneously, achieving omnidirectional coverage without requiring multiple separate lamp units
Solution Approach 2:
The holder structure is designed to serve multiple functions simultaneously: it provides mechanical support for the LED elements, acts as a heat dissipation system through its fins, and functions as a light-diffusing structure. This multi-functionality achieves omnidirectional illumination without proportionally increasing device complexity
3Power
If conventional LED lamps are designed for high power application, then illumination intensity increases, but heat dissipation becomes insufficient causing element damage
Solution Approach 1:
The patent changes the thermal parameters of the lamp structure by using a holder made of metal material with high thermal conductivity instead of conventional insulating materials. The holder's thermal conductivity parameter is optimized to efficiently conduct heat away from high-power LED elements, enabling the lamp to handle higher power ratings while maintaining safe operating temperatures
