Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If LED lighting effects are used in computers, then lighting effects can be generated, but bright spots occur and light guides or diffusion sheets are required
Solution Approach 1:
The patent extracts the projection function from traditional LED lighting components and implements it through a separate projector device that projects images onto the motherboard surface, eliminating the need for complex light guides or diffusion sheets while achieving uniform lighting effects
Solution Approach 2:
The patent introduces a reflective mirror as an intermediary component between the projector and the motherboard surface, enabling the projection of lighting effects without direct contact between the projector and the target surface, thus simplifying the overall system structure
2Adaptability or versatility
If traditional projection methods are used, then images can be projected, but height limitations restrict projector placement
Solution Approach 1:
The patent utilizes the vertical dimension by projecting images onto the top surface of the motherboard and using a reflective mirror to redirect the light, enabling projector placement in locations that were previously inaccessible due to height constraints
Solution Approach 2:
The reflective mirror serves as a mediator that extends the effective projection distance and enables flexible projector placement by redirecting projected images to the target surface without requiring direct line-of-sight alignment
3Adaptability or versatility
If LEDs are used for lighting effects, then on/off states and color changes can be implemented, but limited variations occur
Solution Approach 1:
The patent employs a projector that can display various images and patterns, providing multiple lighting effect variations through a single device, thereby achieving design versatility without increasing overall system complexity
Solution Approach 2:
The patent uses a projector to create visual copies of desired lighting patterns and images on the motherboard surface, enabling diverse lighting effects without requiring multiple physical LED components or complex control circuits
