Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If light guide plates are used in conventional LED light apparatuses, then light distribution can be achieved, but manufacturing complexity and cost increase
Solution Approach 1:
The patent removes the light guide plate component from the conventional LED light apparatus structure. By extracting this component, the invention simplifies the overall device structure, reduces manufacturing complexity, and eliminates the need for precise alignment between the light guide plate and LED modules, while still achieving uniform light distribution through the reflective cavity design
Solution Approach 2:
The patent introduces a reflective cavity with a three-dimensional curved surface as an intermediary structure between the LED modules and the light output surface. This reflective cavity acts as a mediator that redirects and distributes light from the LED modules uniformly across the light output surface, replacing the function previously performed by the light guide plate
2Illumination intensity
If light guide plates are used in conventional LED light apparatuses, then light distribution can be achieved, but installation and replacement difficulty increase
Solution Approach 1:
The patent divides the LED light apparatus into separable modules: LED modules that can be independently installed or replaced, and a reflective cavity structure that remains fixed. This segmentation allows for easy maintenance and replacement of LED modules without requiring specialized tools or complex disassembly procedures, improving ease of operation
Solution Approach 2:
By removing the light guide plate, the patent eliminates the component that previously required precise alignment and complex installation procedures. The simplified structure allows for easier installation and replacement of LED modules, as there is no need to align them with a light guide plate or deal with adhesive removal from the light guide plate surface
3Illumination intensity
If light guide plates are used in conventional LED light apparatuses, then light distribution can be achieved, but total cost increases
Solution Approach 1:
The patent removes the light guide plate, which is identified as a costly and difficult-to-manufacture component. This extraction reduces material costs, manufacturing complexity, and assembly costs, thereby reducing the total cost of the LED light apparatus while maintaining light distribution performance through the reflective cavity design
Solution Approach 2:
The patent employs simpler, cheaper components such as the reflective cavity with three-dimensional curved surface and standard LED modules that can be easily manufactured and replaced. These components are more cost-effective than light guide plates, reducing the overall cost of the apparatus while achieving the desired light distribution
