Wiper Blade Holding Device with Offset Grooves
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wiper blade holding devices require complex assembly processes and have bulkier designs, making them inefficient for packaging and storage, particularly when transitioning from one wiper blade to another during installation.
Innovation Solution
A holding device with side-by-side retaining grooves having common walls, offset openings, and flared shapes, equipped with elastic hooking lugs and shoulders, allowing for simplified assembly by inserting wiper blades from above, reducing the need for device rotation and minimizing bulk through staggered groove arrangement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the holding device uses separate retaining grooves for each wiper blade, then each blade can be securely retained, but the device becomes bulkier and requires more space for packaging and storage
Solution Approach 1:
The patent combines two separate retaining grooves into a single integrated structure with a common bottom wall. The first and second retaining grooves share common lateral walls and a common bottom, allowing both wiper blades to be retained securely while reducing the overall volume of the holding device compared to completely separate grooves.
Solution Approach 2:
The retaining grooves are arranged in a nested configuration where the first and second retaining grooves are positioned one above the other with offset openings. This nesting arrangement allows the grooves to share space efficiently, reducing the lateral bulk of the device while maintaining secure retention for both blades.
2Ease of operation
If the holding device requires turning over after fixing the first blade, then the second blade can be accessed, but the assembly process becomes more complex and time-consuming
Solution Approach 1:
The patent resolves the accessibility issue by arranging the openings of the first and second retaining grooves in offset planes rather than requiring device rotation. The first opening emerges in a first plane and the second opening emerges in a second plane offset from the first, allowing both blades to be accessed from the same side simultaneously, eliminating the need to turn the device over.
3Productivity
If the retaining grooves are arranged side by side with offset openings, then assembly is simplified and bulk is reduced, but the groove geometry becomes more complex
Solution Approach 1:
The holding device is segmented into distinct first and second retaining grooves with separate openings in offset planes. This segmentation allows each groove to be optimized for its specific blade while maintaining a compact overall structure, balancing geometric complexity with assembly simplicity.

AI summary
The present invention relates to a device for supporting a pair of wiper blades (12, 26; 13, 27), comprising first and second supporting grooves (14, 28), each of which is provided with a means for retaining at least one laterally extending structural element (22; 54) of two respective blades (12, 26; 13, 27) by resilient nesting. According to the invention, the supporting grooves (14, 28) are arranged side by side with a common wall, the supporting grooves having two respective openings leading into parallel and offset planes (R1, R2), the second supporting groove (28) being arranged above the first supporting groove (14) and having a substantially flared shape, wherein said openings belong to a single side of the supporting device. The present invention also relates to a supporting assembly comprising a plurality of supporting devices, and to a corresponding mounting method.
