Elastic Holding Device for Wiper Linkage Blocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wiper mechanism wheelhouse blocking elements require tools for installation and removal, generate debris, and are disposable, leading to additional costs and waste.
Innovation Solution
A holding device comprising a clip with elastic arms and a retaining clip that snap-fastens onto the wheelhouse's bearing and connecting rod, allowing for tool-free installation and removal, and remaining on the linkage post-installation to reduce waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If disposable locking elements are used to block the wheelhouse in transport position, then the wheelhouse can be secured during transport, but tools are required for removal and debris is generated that requires treatment
Solution Approach 1:
The holding device is designed to be self-servicing through its elastic arms that automatically engage with the barrel and connecting rod. The elastic arms flex to allow installation without tools and return to their original position to secure the linkage, eliminating the need for external tools during both installation and removal operations.
Solution Approach 2:
The elastic arms change their physical state by flexing and deforming elastically during installation and removal. This parameter change allows the arms to temporarily yield to permitting engagement and disengagement without tools, while maintaining secure locking during transport when in their rigid, engaged state.
2Reliability
If disposable locking elements are used, then the wheelhouse can be blocked in transport position, but additional costs are incurred for tool usage and waste treatment
Solution Approach 1:
Instead of discarding the holding device after single use, the design allows it to be recovered and reused. The elastic arms and modular construction enable the device to maintain its functional properties after removal, allowing it to be reused on subsequent wheelhouses, thereby reducing waste and associated treatment costs.
Solution Approach 2:
The holding device is designed as an inexpensive component that can be easily replaced if needed, but its reusability extends its service life. The simple elastic arm mechanism and lack of complex materials keep production costs low while enabling multiple uses, reducing the frequency of disposal.
3Reliability
If complex locking mechanisms are used to secure the wheelhouse, then reliable blocking is achieved, but installation becomes complicated requiring tools
Solution Approach 1:
The holding device is segmented into distinct functional components: the clip with elastic arms for engaging the barrel, and the retaining clip for securing the connecting rod. This segmentation allows each component to be optimized for its specific function while simplifying the overall installation process, as each segment can be independently engaged without requiring tools.
Solution Approach 2:
The traditional mechanical locking system requiring screws, clips, or other fastening mechanisms is replaced with an elastic deformation-based system. The elastic arms use their inherent material properties to create the locking action, eliminating the need for separate fastening components and tools while maintaining reliable blocking.
