Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If LED is used as light source, then energy efficiency is improved and lifespan is extended, but heat generation increases causing deterioration of light emitting performance
Solution Approach 1:
The patent combines the electromagnetic wave shielding function and heat radiating function into a single integrated structure. The frame is constructed with electromagnetic wave shielding material that also possesses thermal conductivity, allowing it to simultaneously shield electromagnetic waves from the controller and radiate heat from the LED light source, thereby resolving the contradiction between energy efficiency improvement and heat generation without requiring separate components
Solution Approach 2:
The frame is designed to perform multiple functions: structural support, electromagnetic wave shielding, and heat radiation. By making the frame兼具 electromagnetic wave shielding capability and thermal conductivity, the patent creates a universal component that addresses both electromagnetic interference and thermal management issues, allowing the system to maintain high energy efficiency while managing heat effectively
2Temperature
If large heat radiating structures are added, then heat emission is improved, but device size increases
Solution Approach 1:
The patent merges the heat radiating function into the existing frame structure rather than adding separate heat radiating components. The frame is designed with thermal conductivity to radiate heat from the LED, eliminating the need for additional large heat radiating structures and thereby maintaining compact device size while achieving effective heat emission
Solution Approach 2:
The frame serves as both structural support and heat radiating component. By giving the frame dual functionality, the patent avoids adding extra components that would increase device volume, thus resolving the contradiction between improving heat emission and maintaining compact size
3Object-affected harmful factors
If separate electromagnetic wave shields are added, then electromagnetic interference protection is improved, but device complexity and size increase
Solution Approach 1:
The patent combines electromagnetic wave shielding material into the frame structure itself, creating an integrated component that provides both structural support and electromagnetic interference protection. This eliminates the need for separate electromagnetic wave shields, thereby reducing device complexity and component count while maintaining effective shielding
Solution Approach 2:
The frame is designed to simultaneously provide structural support and electromagnetic wave shielding. By making the frame兼具 these two functions, the patent reduces the total number of components needed, simplifying the device structure while maintaining comprehensive electromagnetic interference protection
