Curved Display Frame Assembly with Angled Coupling Holes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In curved display devices, the curvature of the upper and lower frames leads to varying angles of coupling holes, making it difficult to assemble the frames correctly and resulting in defective fastening, which slows down the assembly process.
Innovation Solution
The design includes coupling portions on the frames with acute angles that adjust based on distance from the center, allowing the fastening members to be inserted in a consistent direction, ensuring proper alignment and assembly efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If coupling holes are formed in curved fastening surfaces of upper and lower frames, then the frames can be assembled together, but the coupling holes have different angles at different positions making fastening difficult and error-prone
Solution Approach 1:
The coupling portions are designed with different inclination angles according to their positions on the curved frames. Specifically, coupling portions at different locations have different inclination angles relative to the horizontal plane, which compensates for the curvature of the frames and ensures that fastening members can be inserted vertically from above without requiring different insertion angles at different positions.
2Reliability
If different insertion directions are used for fastening members at different coupling holes, then proper fastening can be achieved, but the assembling speed slows down
Solution Approach 1:
The coupling portions are pre-designed with specific inclination angles during the manufacturing stage, so that when assembly is performed, the fastening members can be inserted vertically from above at all positions. This preliminary geometric configuration eliminates the need for operators to adjust insertion angles during assembly, thereby maintaining both high reliability of fastening and high productivity of assembly speed.
3Manufacturing precision
If coupling portions are designed with different inclination angles to compensate for frame curvature, then fastening accuracy is improved, but the structural design becomes more complex
Solution Approach 1:
The coupling portions are designed with asymmetric inclination angles that vary according to their positions on the curved frames. Instead of using uniform symmetric coupling holes, each coupling portion is inclined at a different angle relative to the horizontal plane, which matches the curvature of the frame at that specific location. This asymmetric design simplifies the overall structure by eliminating the need for complex adjustable mechanisms.
