Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a lampshade is used to control the light-emitting angle, then the light-emitting angle can be controlled, but the structure becomes bulky and unsuitable for thin lighting fixtures
Solution Approach 1:
The patent extracts the light-emitting angle control function from the traditional lampshade structure. Instead of using a complete lampshade, it employs a lens plate with extraction structures that selectively control light emission angles, significantly reducing the structural volume while maintaining the angle control capability.
Solution Approach 2:
The lampshade structure is segmented into a lens plate with multiple extraction structures. Each extraction structure controls a specific light-emitting angle, allowing the overall structure to be compact while providing multiple angle control options through distributed functional elements.
2Adaptability or versatility
If the lampshade is replaced to change the light-emitting angle, then the light-emitting angle can be adjusted, but the operation becomes inconvenient and time-consuming
Solution Approach 1:
The patent implements a dynamic adjustment mechanism where the lens plate can be rotated relative to the supporting plate through guiding members and elastic-sheet structures. This allows the light-emitting angle to be continuously adjusted without replacing parts, transforming a static structure into a dynamically adjustable one.
Solution Approach 2:
The guiding members with guiding slopes and elastic-sheet structures are pre-configured to provide smooth rotational movement and automatic positioning. This preliminary mechanical design enables easy angle adjustment by simply rotating the lens plate, without requiring complex operations or part replacements.
3Device complexity
If a fixed lampshade structure is used, then the structure is simple, but the light-emitting angle cannot be adjusted
Solution Approach 1:
The patent introduces minimal dynamic elements (rotatable lens plate, guiding members, elastic-sheet structures) into an otherwise simple structure. These elements enable angle adjustment while keeping the overall device complexity low, achieving adaptability without sacrificing structural simplicity.
Solution Approach 2:
The lens plate serves multiple functions: it controls light emission, provides angle adjustment through rotation, and includes extraction structures for precise light direction control. This multi-functionality reduces the need for additional components, maintaining structural simplicity while achieving adjustability.

AI summary
A lamp with an adjustable light emitting angle includes a supporting plate, a lens plate, and a lamp board. An upper side of the supporting plate is disposed with a guiding member, the guiding member has a guiding slope with a varying height, and the supporting plate includes a position-providing openings penetrating through the supporting plate along a vertical direction. The lens plate includes an upper extension plate, and the upper extension plate includes an abutting shaft. The lens plate is disposed below the supporting plate, the upper extension plate passes through the position-providing opening, and the abutting shaft is disposed on the guiding slope. The lamp board is disposed below the supporting plate and is located between the supporting plate and the lens plate. A light emitting angle of the lamp is configured to be adjusted by changing a distance between the lamp board and the lens plate.
