Windscreen Wiper Spacer Mounting Head Distance Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing windscreen wiper devices for vehicles often require complex machinery and tools due to multiple parts with dedicated shapes, leading to high costs and potential deterioration in wiping performance if the mounting head is not properly attached.
Innovation Solution
A windscreen wiper device with a detachable spacer connected to the mounting head maintains a predetermined distance from the windscreen, ensuring proper mounting and improved wiping performance, using a simple design that eliminates the need for intermediate oscillating arms and complex machinery, and allows for customization with different spacers for various vehicle types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If an intermediate oscillating arm is used to connect the mounting head to the wiper blade, then the structural stability is improved, but the device complexity increases and manufacturing costs increase
Solution Approach 1:
The patent removes the intermediate oscillating arm from the wiper system, directly connecting the mounting head to the wiper blade. This extraction of the unnecessary intermediate component simplifies the overall structure while maintaining functional stability through the direct connection and proper positioning of the wiper blade against the oscillating arm.
2Device complexity
If the mounting head is directly connected to the wiper blade without a spacer, then the device complexity is reduced, but the wiping performance deteriorates due to improper mounting distance
Solution Approach 1:
The patent introduces a spacer as an intermediary component between the mounting head and the wiper blade. This spacer ensures the correct mounting distance and proper positioning of the wiper blade, guaranteeing reliable wiping performance while keeping the overall device structure simple and easy to manufacture.
3Reliability
If multiple complex parts with dedicated shapes are used in the wiper arm, then the functional performance is improved, but the manufacturing precision requirements increase and production costs increase
Solution Approach 1:
The patent employs standardized components with universal mounting interfaces that can accommodate different wiper blade types and vehicle models. The mounting head, oscillating arm, and spacer use common geometric features and attachment mechanisms, reducing the need for highly specialized parts while maintaining functional performance across various applications.
