Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If light-guiding strips are connected to rods through screws and self-tapping screws, then the lighting function is achieved, but the structure becomes complex and assembly becomes troublesome
Solution Approach 1:
The patent combines the light-guiding strip, reflective film, and light-emitting elements into an integrated light-emitting assembly that is inserted as a single unit into the hollow rod. This merging of components eliminates the need for multiple separate connections using screws and self-tapping screws, thereby simplifying the overall structure while maintaining the lighting function.
Solution Approach 2:
The light-emitting assembly is nested within the hollow rod structure. The light-guiding strip is positioned inside the hollow rod, with the reflective film attached to its back surface and light-emitting elements mounted on it. This nested arrangement allows the lighting components to be housed within the existing rod structure without requiring additional external mounting hardware.
2Reliability
If light-guiding strips are clamped and attached with multiple fasteners, then the lighting function is achieved, but machining becomes difficult
Solution Approach 1:
By combining the light-guiding strip, reflective film, and light-emitting elements into a pre-assembled unit, the patent eliminates the need for complex machining operations on the rods to create slots or mounting holes. The integrated assembly can be manufactured separately and then inserted into the hollow rod, significantly simplifying the machining requirements.
3Reliability
If multiple screws and self-tapping screws are used to attach light-guiding strips, then the lighting function is achieved, but maintenance becomes inconvenient
Solution Approach 1:
The patent segments the lighting system into a modular light-emitting assembly that can be independently removed from the hollow rod. This segmentation allows the lighting components to be easily extracted for maintenance or replacement without disassembling the entire umbrella structure, making maintenance much more convenient compared to fixed attachments with multiple fasteners.
4Reliability
If rods are slotted to accommodate light-guiding strips, then the lighting function is achieved, but assembly becomes troublesome
Solution Approach 1:
The light-emitting assembly is designed to be nested within the hollow rod without requiring slots to be cut into the rod structure. The assembly is inserted through the open end of the hollow rod and positioned inside, eliminating the need for complex slotting operations and simplifying the assembly process.
