Wiper Arm Mount Integrating Cleaning Arrangement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wiper devices for vehicle windows have a cumbersome and complex design due to the separate arrangement of the cleaning arrangement and the wiper blade fastening arrangement, leading to a wide and complicated wiper arm cross-section.
Innovation Solution
A wiper device with a U-shaped mount cross-section that integrates the cleaning arrangement and wiper blade fastening arrangement, allowing for a compact design and simple connection types such as engagement, form-fitting, or bayonet connections, enabling easy mounting and dismounting of the cleaning arrangement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the cleaning arrangement and wiper blade fastening arrangement are arranged separately, then the cleaning function can be provided, but the wiper arm cross-section becomes cumbersome and complex
Solution Approach 1:
The patent combines the cleaning arrangement and the wiper blade fastening arrangement into a single integrated mount structure. The U-shaped cross-section of the mount simultaneously provides the cleaning arrangement mounting surface and the wiper blade fastening mechanism, eliminating the need for separate structures and simplifying the overall wiper arm design.
Solution Approach 2:
The U-shaped mount structure serves multiple functions: it provides the structural support for the cleaning arrangement, contains the wiper blade fastening arrangement, and enables both cleaning and blade attachment functions within a single component. This multi-functionality reduces the number of separate components needed.
2Volume of moving object
If the cleaning arrangement is integrated into the U-shaped mount, then the design becomes compact, but the connection method must be simplified
Solution Approach 1:
The cleaning arrangement is designed as a separable component that can be independently mounted and dismounted from the wiper arm. The engagement connection allows the cleaning arrangement to be attached to the U-shaped mount and detached when needed, providing ease of maintenance and replacement while maintaining a compact integrated design.
Solution Approach 2:
The connection system transitions from a fixed permanent attachment to a dynamic reversible connection. The engagement connection mechanism allows the cleaning arrangement to be easily attached and detached, providing operational flexibility while maintaining structural integrity during use.
3Reliability
If multiple spray nozzles are added for optimal window coverage, then the cleaning action is enhanced, but the cleaning arrangement complexity increases
Solution Approach 1:
Multiple spray nozzles are strategically positioned at different locations on the cleaning arrangement to target specific regions of the window. Each nozzle is placed to optimize coverage of particular areas, ensuring comprehensive cleaning effectiveness while maintaining a relatively simple overall structure.
