Window Wiper Accessory Fastening Above Cleaning Strip Axis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing window wiper assemblies with detachable accessories face challenges such as increased difficulty in handling and risk of damage due to the space taken up by fastening means, which also hinder the wiping process and can cause damage to windows or frames.
Innovation Solution
The window wiper assembly features a holder with fastening elements that allow the accessory to be connected in at least two positions, with each fastening element situated above the axis of the cleaning strip during use, minimizing obstruction and the risk of contact with the surface, enabling easier handling and reduced risk of damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fastening means are provided to detachably attach accessory to window wiper, then accessory can be connected to window wiper, but the fastening means takes up space and makes the window wiper difficult to handle
Solution Approach 1:
The fastening element is positioned above the axis of the cleaning strip, utilizing the vertical dimension to place the fastening mechanism out of the horizontal wiping path. This spatial repositioning allows the fastening means to be functionally present without physically obstructing the wiping motion, thereby maintaining handling ease while enabling accessory attachment.
Solution Approach 2:
The holder is divided into functional zones: the cleaning strip area for wiping and the fastening element area for accessory attachment. This segmentation allows each component to perform its function independently without interfering with the other, resolving the contradiction between attachment capability and handling ease.
2Adaptability or versatility
If fastening means are provided to detachably attach accessory to window wiper, then accessory can be connected to window wiper, but the fastening means may cause damage to the window
Solution Approach 1:
By positioning the fastening element above the cleaning strip axis, the design moves the potential harm source out of the contact zone with the window surface. The fastening means remains in the vertical dimension above the wiping path, eliminating the risk of damage to the window while preserving accessory attachment functionality.
Solution Approach 2:
The fastening element is extracted from the cleaning strip area and relocated to a separate position above the axis. This extraction removes the potential harmful factor from the interaction zone between the window wiper and the window surface, preventing damage while maintaining the attachment function.
3Adaptability or versatility
If additional fastening means are provided to enable additional ways of handling, then versatility of handling is improved, but device complexity increases
Solution Approach 1:
The single fastening element positioned above the axis serves multiple functions: it allows accessory attachment and enables the cleaning strip to be folded in multiple directions (above or below the holder). This multi-functionality achieves versatile handling positions without requiring multiple separate fastening mechanisms, thus avoiding increased device complexity.
Solution Approach 2:
The fastening element is combined with the holder structure in such a way that it provides both attachment functionality and folding flexibility. By merging these functions into a single integrated design, the system achieves multiple handling positions without adding separate components, maintaining simplicity while enhancing versatility.
