Wiper Blade Support Mount Recesses for Flexibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional windscreen wiper systems lack sufficient flexibility, especially in extreme climatic conditions, due to insufficient design features in the support frame, which affects their performance in clearing water and maintaining aerodynamics.
Innovation Solution
A support mount for the windscreen wiper blade with recesses facilitating bending, enhancing flexibility in both longitudinal and torsional directions, and featuring a design that reduces friction during assembly with an aerodynamic deflector, including lateral fins with harpoons and an open upper housing with complementary recesses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the upper housing of the support frame is closed, then structural strength is improved, but flexibility in extreme climatic conditions deteriorates
Solution Approach 1:
The patent applies local quality by making the upper housing open specifically in the middle section while keeping other areas closed. This localized opening provides flexibility where needed (in extreme cold) while maintaining structural strength in other critical areas of the housing.
Solution Approach 2:
The upper housing is segmented into open and closed sections. The middle portion is opened to allow flexibility, while the rest of the housing remains closed to maintain structural integrity. This segmentation resolves the contradiction between strength and flexibility.
2Stability of the object's composition
If the support frame is made rigid, then structural stability is improved, but assembly friction with the deflector increases
Solution Approach 1:
The patent introduces recesses at specific locations (second means for retaining the deflector) to reduce friction during assembly. These localized recesses allow the deflector to slide in more easily without compromising the overall structural stability of the rigid support frame.
3Adaptability or versatility
If recesses are added to the second means, then flexibility and assembly ease are improved, but device complexity increases
Solution Approach 1:
The patent modifies the geometric parameters of the second means by adding recesses to its structure. This parameter change (adding recesses) increases flexibility and reduces assembly friction, while the complexity increase is minimal and localized to specific areas of the support frame.
