Wiper Blade Connection Device for Universal Vehicle Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wiper system connection devices are complex, fragile, and unsuitable for easy mounting on vehicles with either right-hand or left-hand drive, lacking versatility and optimized visibility for drivers.
Innovation Solution
A simplified, compact connection device with a stud and housing system, featuring a finger and pin configuration, allowing easy assembly on both right-hand and left-hand drive vehicles, comprising a one-piece assembly made from polymer material with a receiving member for the tongue, enabling optimized visibility and reduced part count.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional connection device is used between the operating arm and wiper blade, then the wiper blade can be attached to the arm, but the device becomes complex and fragile with a large number of parts
Solution Approach 1:
The patent merges multiple separate components (stud, housing, receiving member, tongue) into a single integrated connection device that attaches between the operating arm and wiper blade. This consolidation reduces the total number of parts while maintaining reliable mechanical connection through the interlocking stud-housing and tongue-receiving member interfaces.
Solution Approach 2:
The connection device is designed with universal adaptability to work with different operating arm configurations (right-hand drive or left-hand drive vehicles). The stud and housing structure can accommodate various mounting orientations, allowing the same device to serve multiple vehicle types without modification.
2Adaptability or versatility
If a traditional connection device is used, then the wiper blade can be mounted, but it is not suitable for easy mounting on vehicles with either right-hand or left-hand drive
Solution Approach 1:
The connection device incorporates universal mounting capabilities through its symmetric stud-housing design that can be installed in multiple orientations. The same device works equally well on right-hand drive and left-hand drive vehicles, eliminating the need for different connection devices for different vehicle configurations.
Solution Approach 2:
The connection device is divided into separable components (stud with housing, tongue with receiving member) that can be independently positioned and assembled. This segmentation allows flexible installation orientations to accommodate different vehicle types while maintaining ease of assembly through simple attachment operations.
3Reliability
If a complex connection device with many parts is used, then connection functionality is achieved, but production, referencing and storage costs increase
Solution Approach 1:
By consolidating multiple functions into fewer integrated components, the patent reduces manufacturing complexity and part inventory requirements. The merged design requires fewer production steps, simplifies quality control, and reduces storage space needed for multiple variants, thereby lowering overall production costs while maintaining reliable connection functionality.
