Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the light emitting angle is fixed, then the structure is simple, but the adaptability to different lighting requirements is poor
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed light emitting angle into an adjustable one through a folding mechanism. The lamp body can be folded to change the light emitting angle from 120 degrees to 300 degrees, allowing the structure to adapt to different lighting requirements while maintaining operational simplicity through mechanical folding action.
2Adaptability or versatility
If the irradiation area is fixed, then the manufacturing is simple, but the ability to meet diverse lighting requirements is limited
Solution Approach 1:
The patent implements dynamic adjustment of the irradiation area through the folding mechanism. By folding the lamp body, the effective irradiation area can be expanded or contracted according to lighting needs, while the manufacturing remains relatively simple as it uses standard assembly processes with added hinge and rotating shaft components.
3Illumination intensity
If multiple lamps are used to increase illumination coverage, then the lighting requirements are met, but the energy consumption increases
Solution Approach 1:
The patent uses the folding mechanism to dynamically adjust the light emitting angle up to 300 degrees, allowing a single lamp to cover an area that would traditionally require multiple lamps. This reduces the total number of light sources needed, thereby decreasing overall energy consumption while maintaining adequate illumination coverage.
Solution Approach 2:
The patent makes a single lamp perform multiple functions by enabling it to adjust its light emitting angle to cover different areas. This multi-functionality allows one lamp to replace what would traditionally require multiple fixed-angle lamps, reducing energy consumption while meeting diverse lighting requirements.
4Area of stationary object
If the light rays undergo diffuse reflection or multiple refractions, then the light distribution is widespread, but the light loss increases
Solution Approach 1:
The patent dynamically adjusts the light emitting angle to optimize direct illumination rather than relying on diffuse reflection. By folding the lamp to achieve a 300-degree emission angle, the system directs light more efficiently to the target area, reducing the need for multiple reflections and refractions that cause energy loss.

AI summary
A deformable LED lamp configured to change a light emitting angle by folding comprises a fixed light source, one or more movable light sources, and an end cover. The one or more movable light sources are rotatably connected to the end cover through a rotating shaft, and the one or more movable light sources are configured to rotate about the rotating shaft to change an included angle between the fixed light source and the one or more movable light sources. One side of a LED light source board facing away from a light emitting surface of the LED light source board is connected with a heat sink to enable heat conduction between the LED light source board and the heat sink. The heat sink of the fixed light source and the heat sink of the one or more movable light sources are rotatably connected together through a hinge.
