Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple light guides with different light emitting surfaces are added to provide diverse light radiation angles, then the aesthetic versatility is improved, but the device complexity increases
Solution Approach 1:
The patent combines multiple light guides (first light guide with first light emitting surfaces, second light guide with second light emitting surfaces) into a single integrated assembly that mounts to the chassis together. This merging approach allows diverse light radiation angles and aesthetic combinations while managing the complexity through unified installation and configuration.
2Strength
If traditional fasteners requiring tools and multiple steps are used to assemble cooling fan components, then the connection strength is improved, but the ease of assembly and disassembly deteriorates
Solution Approach 1:
The patent replaces traditional mechanical fasteners requiring tools with a snap-fit engagement system. The light guides include engagement features that mechanically interlock with corresponding features on the chassis and cover, providing sufficient connection strength while enabling tool-free assembly and disassembly through simple insertion and removal actions.
3Ease of repair
If cooling fan components are designed for easy tool-free assembly, then the ease of repair and maintenance is improved, but the reliability of component connection may deteriorate
Solution Approach 1:
The patent segments the cooling fan into modular components (chassis, light guides, cover, blades) that can be independently assembled and disassembled. The engagement features are designed to provide reliable connections during normal operation while allowing intentional easy separation when needed for maintenance or repair, achieving both ease of repair and connection reliability through thoughtful mechanical design.
