Wiper Retaining Support Structure for Pane Edge Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wipers struggle to effectively clean the perimeter of panes, as the wiping edge tends to move from the pane onto the rim, leading to incomplete cleaning and the need for additional wiping elements.
Innovation Solution
A wiper design featuring a flexible cleaning strip with retaining supports at its ends, made of a material with lower elasticity than the strip, which restricts the strip's movement and keeps the wiping edge in contact with the pane, preventing it from bending towards the rim.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If additional wiping elements such as rags are used to wipe the pane at the rim location, then proper cleaning can be achieved, but the process becomes labour-intensive and time-consuming
Solution Approach 1:
The retaining supports at the ends of the holder automatically perform the function of preventing the wiping edge from moving onto the rim during the normal wiping motion. This self-service mechanism eliminates the need for additional wiping elements like rags, thus achieving complete cleaning without increasing labor or time requirements.
2Length of moving object
If the wiping strip protrudes beyond the holder along its entire length, then the wiping edge can extend fully across the pane, but the holder cannot effectively restrict the wiping strip's movement to prevent it from moving onto the rim
Solution Approach 1:
The holder provides different levels of support along the length of the wiping strip: minimal restriction in the central portion to allow full extension and free motion, and localized restriction at the ends through retaining supports to maintain position stability. This local differentiation resolves the contradiction between length and stability.
Solution Approach 2:
The holder is segmented into a central portion that allows full wiping edge extension and end portions with retaining supports that provide localized stability. This segmentation enables the wiping edge to maintain both its full length and positional stability during operation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The wiper ensures complete cleaning of the pane perimeter without additional tools, as the retaining supports maintain the wiping edge in contact with the pane, reducing the risk of it moving onto the rim and allowing efficient wiping without labor-intensive additional elements.
Implementation Method 1
the holder, at the location of the two ends of the wiping strip, comprises a respective retaining support with a support surface which extends opposite the top surface of the wiping strip... the distance between the support surface of the retaining supports and the top surface of the wiping strip diminishes towards the ends of the wiping strip

AI summary
Wiper (1) comprising an elongate cleaning strip (2) which is substantially made of flexible material and a holder (3) for fixing the cleaning strip (2). Viewed along the longitudinal direction (9) of the cleaning strip (2), the cleaning strip (2) comprises a wiping edge (4) for wiping panes, and a wiping strip (5) comprising said wiping edge (4) which extends beyond the holder (3) along substantially its entire length. The holder (3) furthermore comprises retaining supports (6) which, at the location of the ends (7) of the wiping strip (5), extend along the wiping strip (5) almost as far as the wiping edge (4).
