Rolling Screen Thickening Groove Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile screen connection systems to handle bars, such as sun screens, curtains, and mosquito nets, exhibit visible welding areas that detract from aesthetics and compromise functional efficiency.
Innovation Solution
A sliding and/or rolling mobile screen system featuring a thickening portion applied to the connection edge, which is inserted into a groove on the handle bar, eliminating visible welding and enhancing aesthetic appeal and operational efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a bolt-rope with welded end bands is used to connect the screen to the handle bar, then the connection strength is improved, but the welding area projects from the handle bar creating visible aesthetic defects and reducing functional efficiency
Solution Approach 1:
The invention extracts and removes the welding operation from the connection system. Instead of welding end bands to the bolt-rope, the patent uses mechanical fastening methods (screws, clips, or snap-fit connections) to attach the end bands to the handle bar, completely eliminating visible welding areas and their associated aesthetic defects.
Solution Approach 2:
The invention introduces an intermediary fastening mechanism between the end bands and the handle bar. This intermediary system (screws, clips, or snap-fit elements) serves as a mediator that provides strong mechanical connection without requiring welding, thus resolving the conflict between connection strength and aesthetic appearance.
2Reliability
If a bolt-rope connection system is used to attach the screen to the handle bar, then the connection reliability is improved, but the protruding welding areas reduce functional efficiency
Solution Approach 1:
The invention removes the welding process from the connection system, extracting the source of functional inefficiency. The protruding welding areas that interfered with the screen's sliding and rolling operations are completely eliminated, restoring full functional efficiency while maintaining connection reliability through alternative mechanical fastening methods.
Solution Approach 2:
An intermediary fastening system is introduced that provides reliable mechanical connection without creating protruding elements. This intermediary mechanism (screws, clips, or snap-fit connections) ensures secure attachment while allowing the screen to move smoothly along the handle bar without obstruction.
3Ease of manufacture
If traditional welding methods are used to fasten the end bands, then the manufacturing process is simplified, but the visible welding areas create aesthetic defects
Solution Approach 1:
The invention replaces the welding mechanical system with alternative fastening mechanisms. Instead of using thermal welding processes, the patent employs mechanical fastening methods such as screws, clips, or snap-fit connections, which are equally simple to manufacture but produce no visible welding defects.
Solution Approach 2:
An intermediary fastening component is introduced that simplifies the manufacturing process while eliminating aesthetic defects. These intermediary elements (screws, clips, or snap-fit mechanisms) can be easily attached using standard manufacturing techniques and provide secure fastening without creating visible welding areas.
