Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the emergence angle of the LED lamp is defined to control the illuminating area, then the decorative and illuminating effect is achieved, but the LED lamp cannot adjust to different user demands requiring replacement of lamps which is troublesome and costly
Solution Approach 1:
The patent applies the dynamics principle by making the light distribution board rotatable relative to the light source assembly. The light distribution board can be rotated to different angles to change the illuminating range and direction, transforming a static lighting structure into a dynamic adjustable one. This resolves the contradiction by enabling adaptability without requiring multiple different lamp fixtures, as the single structure can dynamically adjust to various illumination needs.
2Adaptability or versatility
If the light distribution board is made rotatable to adjust illuminating range, then adaptability is improved, but the positioning stability may be compromised
Solution Approach 1:
The patent applies beforehand cushioning by introducing a damping assembly that provides frictional resistance to the rotation of the light distribution board. The damping assembly creates a cushioning effect that prevents the board from rotating freely or accidentally shifting, while still allowing intentional adjustment. This resolves the contradiction by providing positioning stability through friction-based cushioning while maintaining the rotatable adjustability feature.
3Stability of the object's composition
If damping assemblies are added to provide rotation damping force, then positioning stability is improved, but the device complexity increases
Solution Approach 1:
The patent applies flexible shells and thin films by using a damping assembly that incorporates friction-based elements (such as friction pads or damping materials) to provide rotation damping force. This flexible damping mechanism adds minimal structural complexity compared to rigid mechanical locking systems, while effectively providing positioning stability. The damping assembly integrates smoothly with the existing rotatable structure, adding only necessary components for friction-based stabilization.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables flexible adjustment of the illuminating range and area, meeting various user demands without the need for frequent lamp replacements, enhancing both decorative and illuminating effects while reducing operational costs.
Implementation Method 1
The adjusting mechanism is provided with a first damping assembly configured to provide a rotation damping force for the light distribution board. The first damping assembly is a rubber gasket arranged at a rotating joint of the light distribution board.
Implementation Method 2
A second damping assembly is arranged between the lamp housing and the base, and configured to provide a rotation damping force for the lamp housing. The second damping assembly is a rubber ring arranged at a junction of the lamp housing and the base.

AI summary
An LED lamp with an adjustable illuminating range is provided, including a lamp body. The lamp body includes a base, a lamp housing arranged on the base, and a light source assembly arranged inside the lamp housing. At least one side of the lamp housing includes an open structure allowing light from the light source assembly to emit. An adjusting mechanism is configured inside the lamp housing to adjust the illuminating range of the light emitted from the light source assembly. An emergence angle of the light source assembly or a size of the opening structure can be adjusted by the adjusting mechanism, thereby adjusting the illuminating range or an illuminating area of emitted light and meeting different user demands.
