Wiper Arm Cleaning Arrangement Guide Means
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wiper devices for vehicle windows require a large mount region for both the cleaning arrangement and the fastening arrangement, making them bulky and complicating the mounting process of the wiper blade.
Innovation Solution
The wiper device integrates the cleaning arrangement to hold the fastening arrangement, utilizing guide means such as elevations and depressions to facilitate intuitive and straightforward mounting by guiding the fastening arrangement during assembly and disassembly, ensuring a secure and compact design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the cleaning arrangement and fastening arrangement are arranged separately on the wiper arm, then both arrangements can be accommodated, but the mount region becomes large and bulky
Solution Approach 1:
The cleaning arrangement is designed to also serve as the fastening arrangement. The cleaning arrangement includes a holder that receives the wiper blade, thereby combining the cleaning function and fastening function into a single integrated component on the wiper arm, eliminating the need for separate arrangements and reducing the mount region size.
2Ease of operation
If the cleaning arrangement holds the fastening arrangement with guide means, then mounting becomes intuitive and straightforward, but the structure becomes more complex
Solution Approach 1:
The guide means are integrated into the holder structure itself, using the holder's own geometric features (elevations and depressions) to guide the wiper blade during mounting. This self-guiding mechanism eliminates the need for separate external guiding components, providing intuitive mounting while avoiding additional structural complexity.
