Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional slotting processes and fastener-based assembly are used for mounting PCBs with LED lights on umbrella ribs, then lighting function is achieved, but production and assembly costs increase
Solution Approach 1:
The patent extracts the lighting components (PCB with LED lights and light-transmitting plates) from the traditional rib structure and relocates them to the umbrella disc. This eliminates the need for slotting ribs and using fasteners, thereby reducing manufacturing complexity and assembly costs while maintaining the lighting function.
Solution Approach 2:
The patent merges the lighting components directly into the umbrella disc structure, combining the PCB, LED lights, and light-transmitting plates into an integrated assembly that is mounted as a single unit on the umbrella rod, simplifying both production and assembly processes.
2Illumination intensity
If conventional lighting design is used with PCBs and light-transmitting plates on ribs, then illumination is provided, but all-directional light emission cannot be achieved
Solution Approach 1:
The patent transitions from linear light emission along the ribs to three-dimensional all-directional light emission by positioning the light-transmitting plates on the umbrella disc, which radiates light in multiple directions simultaneously, achieving omnidirectional illumination.
Solution Approach 2:
The patent uses light-transmitting plates with different translucency levels arranged asymmetrically on the umbrella disc to optimize light distribution in various directions, enhancing the all-directional light emission capability.
