Wiper Connection Cover With Detachable Bearing for Arm Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wiper system connection devices are aesthetically compromised by visible components and are complex to disengage, particularly when switching between 'hook arm' and 'pin arm' types, as the cover designed for one type interferes with the other, requiring removal and reinstallation.
Innovation Solution
A rotatably mounted cover with a bearing and tab design allows easy disengagement from the adapter, featuring a hollow cylindrical shape with an axial opening and a semi-circular tab for disassembly, along with retaining means to secure the cover in place, facilitating quick adaptation between different wiper arm types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a cover is added to conceal components and improve aesthetics, then the aesthetic appearance is improved, but the device complexity increases and the cover interferes with pin arm types requiring removal
Solution Approach 1:
The cover is segmented into a main body and a separate bearing component. The bearing is designed as an independent element that can be easily detached from the cover, allowing the cover to remain on the adapter while the bearing is removed for pin arm compatibility. This segmentation resolves the contradiction by maintaining the aesthetic cover in place while enabling easy disassembly when needed.
2Reliability
If a cover is designed to secure hook arm connections, then the connection security is improved, but the cover interferes with pin arm installation requiring removal
Solution Approach 1:
The bearing is designed with dynamic characteristics that allow it to be easily inserted and removed. The tab feature provides a mechanical advantage that enables simple rotational movement for bearing installation and removal. This dynamic design allows the cover to provide secure connection for hook arms when needed, while allowing quick bearing removal for pin arm compatibility, thus resolving the contradiction between connection security and adaptability.
3Shape
If the cover is made to rotate and close over components, then the component concealment is improved, but the disengagement process becomes complex
Solution Approach 1:
The bearing is extracted as a separate, easily removable component from the cover assembly. The tab feature on the bearing provides a convenient gripping point that allows users to easily remove the bearing from the cover without complex tools or procedures. This extraction principle resolves the contradiction by maintaining the rotatable cover for aesthetic concealment while enabling simple bearing removal for adaptability needs.
