Universal Wiper Support Device with Asymmetric Fixing Orifice
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current windshield wiper support devices for vehicles require different designs for 'right-hand drive' and 'left-hand drive' vehicles, leading to increased manufacturing costs and complexity due to distinct layouts and interfaces.
Innovation Solution
A single, stamped support device with a predefined fixing orifice positioned on the right for 'right-hand drive' and left for 'left-hand drive' vehicles, featuring a central tunnel conformation for optimized stiffness and lateral adaptations to accommodate various environmental constraints, allowing the wiper to be attached in a central zone regardless of vehicle type.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate support devices are designed for right-hand drive and left-hand drive vehicles, then the device can be adapted to specific vehicle configurations, but the manufacturing cost and design complexity increase
Solution Approach 1:
The support device is designed with a central tunnel conformation that provides a predefined fixing orifice positioned differently depending on the vehicle type. This single universal design can be adapted to both right-hand drive and left-hand drive vehicles through the strategic positioning of the fixing orifice within the tunnel structure, eliminating the need for completely separate designs while maintaining vehicle-specific adaptability
Solution Approach 2:
The central tunnel conformation of the support device creates an asymmetric structure that allows for flexible positioning of the fixing orifice. This asymmetric design enables the same support device to accommodate different vehicle configurations by positioning the fixing orifice on the appropriate side (right or left) depending on whether it's installed in a right-hand drive or left-hand drive vehicle

Solution Approach 2:
The position of the fixing orifice within the central tunnel conformation can be varied depending on the vehicle type. By changing the positional parameter of the fixing orifice within the same support device structure, the device can be adapted to different vehicle configurations without requiring completely separate manufacturing processes, thereby reducing manufacturing costs
