Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a light guide plate is used in conventional LED lighting devices, then light diffusion and uniform illumination are achieved, but the device thickness increases and flexibility is lost
Solution Approach 1:
The patent removes the light guide plate from the conventional LED lighting structure, extracting the light diffusion function to a separate optical element (diffuser film or lens) that can be applied directly over the LED array. This eliminates the thickness constraint while maintaining uniform illumination through optical diffusion.
Solution Approach 2:
The patent employs thin flexible diffuser films or optical sheets instead of rigid light guide plates. These thin films can be easily applied to various surfaces including curved ones, providing both uniform light diffusion and design flexibility while minimizing device thickness.
2Stability of the object's composition
If a rigid light guide plate is used, then structural stability is maintained, but flexibility and ease of application to curved surfaces are lost
Solution Approach 1:
The patent replaces rigid light guide plates with flexible thin films that can conform to curved surfaces and various geometries. These films maintain structural integrity through their material properties while enabling easy application to diverse surfaces including dashboards and curved panels.
Solution Approach 2:
The patent transitions from a rigid three-dimensional light guide plate structure to a thin two-dimensional flexible film that can be applied conformally to surfaces. This dimensional reduction enables flexibility and adaptability while the film's tensile strength maintains sufficient structural stability.
3Ease of manufacture
If conventional LED lighting devices are designed for simple plan illumination, then manufacturing is straightforward, but design versatility and three-dimensional lighting effects are limited
Solution Approach 1:
The patent implements varying optical properties at different locations by using patterned diffuser films or lenses with different diffusion characteristics. This allows creation of three-dimensional lighting effects, accent lighting zones, and varied illumination patterns while maintaining a relatively simple overall manufacturing process.
Solution Approach 2:
The patent enables dynamic lighting effects through controllable LED elements that can be independently adjusted in intensity and timing, combined with optical elements that create three-dimensional light distribution. This provides design versatility for animations, mood lighting, and information display while building upon conventional LED control systems.
