Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the light bar is fixed on the metal back plate or thermal fin by screw, then the fixing strength is improved, but the assembly complexity increases and labor time is wasted
Solution Approach 1:
The patent replaces the traditional screw-based mechanical fastening system with a clamp structure that uses elastic deformation and frictional force. The clamp board utilizes its own flexibility to generate clamping force, eliminating the need for screws, nuts, and other complex mechanical fastening components, thereby simplifying the assembly process while maintaining secure fixation.
Solution Approach 2:
The patent changes the physical state of the clamp board from rigid to elastically deformable. By selecting appropriate material properties and thickness, the clamp board can elastically deform during assembly to wrap around the base, generating sufficient clamping force through elastic recovery. This parameter change enables simple snap-together assembly without complex fastening mechanisms.
2Ease of operation
If the light bar is adhered on the back plate or thermal fin by glue, then the assembly is convenient and low cost, but the light bar cannot be reused once glued
Solution Approach 1:
The clamp structure is designed to be self-adjusting and self-locking through elastic deformation. The clamp board automatically adjusts to the base dimensions and secures itself through elastic recovery, eliminating the need for adhesives. This design allows for easy disassembly and reassembly, enabling the light bar to be reused multiple times while maintaining simple assembly operations.
3Strength
If the light bar is fixed by screw for large-size display module, then the fixing strength is improved, but mechanical damage occurs due to inappropriate locking operation
Solution Approach 1:
The patent replaces the screw-based mechanical fastening system with a clamp structure that uses elastic deformation and frictional force. The clamp board utilizes its own flexibility to generate clamping force, eliminating the need for screws, nuts, and other complex mechanical fastening components, thereby simplifying the assembly process while maintaining secure fixation.
Solution Approach 2:
The elastic nature of the clamp board provides inherent cushioning during the assembly process. As the clamp board is bent to wrap around the base, the elastic material absorbs impact forces and prevents excessive stress concentration that could cause mechanical damage to the light bar or base, ensuring gentle and damage-free assembly.
4Strength
If the light bar with thin thickness is fixed by screw, then the fixing is achieved, but the thin display module cannot accommodate the screw fixation method
Solution Approach 1:
The patent changes the physical state of the clamp board from rigid to elastically deformable. By selecting appropriate material properties and thickness, the clamp board can elastically deform during assembly to wrap around the base, generating sufficient clamping force through elastic recovery. This parameter change enables simple snap-together assembly without complex fastening mechanisms.
Solution Approach 2:
The clamp structure transitions from a static rigid connection to a dynamic elastic system. The clamp board's ability to deform and recover provides adaptability to various base dimensions and thicknesses, making the fixation method compatible with thin display modules where traditional screw fixation would be impractical or damaging.

AI summary
A clamp structure includes a first board portion, a second board portion connected to a lateral side of the first board portion in an elastically deformable manner, and a third board portion connected to the other lateral side of the first board portion opposite to the second board portion in an elastically deformable manner. The third board portion and the second board portion are disposed on the same side of the first board portion for clamping two surfaces of a base, and the first board portion contacts against a light bar for fixing the light bar on the other surface of the base.
