Wiper Blade Hydraulic Connector Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current windshield wiper blade designs face challenges in standardization due to the need for distinct molds for wiper blades with and without liquid circulation conduits, and are not compatible with butterfly-type wiping systems where arms move in opposing directions.
Innovation Solution
A wiper blade with a hydraulic connector that is independent of the mechanical connector, allowing for the distribution of windscreen washing liquid to projection ramps, and featuring a metal stiffening device that maintains contact pressure and is compatible with both unidirectional and bidirectional arm movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wiper blades are equipped with liquid circulation conduits integrated into the mechanical connector, then the projection function is achieved, but manufacturing standardization is limited requiring separate molds
Solution Approach 1:
The invention separates the hydraulic connector (with liquid circulation conduit) from the mechanical connector. The hydraulic connector is a distinct component that can be independently manufactured and then assembled with the mechanical connector, allowing standardization of the mechanical connector while adding projection functionality through the separate hydraulic component.
Solution Approach 2:
The liquid circulation conduit is extracted from the mechanical connector structure and placed into a separate hydraulic connector component. This extraction allows the mechanical connector to remain standardized while the projection function is achieved through the dedicated hydraulic connector that can be added or removed as needed.
2Device complexity
If the hydraulic connector is integrated with the mechanical connector, then structural compactness is achieved, but independence and ease of assembly are reduced
Solution Approach 1:
The hydraulic connector and mechanical connector are segmented as separate components rather than being integrated into a single piece. This segmentation allows each component to be manufactured independently using optimized processes and then assembled together, significantly improving ease of assembly and maintenance while maintaining compact overall structure through their close proximity.
