Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wiper systems for motor vehicles have complex, fragile, and multi-part connection devices that are not suitable for easy installation on vehicles with either right-hand or left-hand drive configurations, limiting their adaptability and driver visibility.
Innovation Solution
A simplified, compact connection device with a holding part and an intermediate part, featuring a channel system and interlocking mechanisms that allow for flexible positioning and easy assembly on both right-hand and left-hand drive vehicles, ensuring optimized driver visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex multi-part connection device is used, then the connection between operating arm and wiper blade is secure, but the device becomes fragile and difficult to assemble on different vehicle configurations
Solution Approach 1:
The patent combines multiple separate connection components into a single integrated connection device. The device includes an operating arm, wiper blade, and connection mechanism all merged into one unit that can be installed as a single assembly, eliminating the need for multiple separate parts and reducing overall complexity while maintaining secure connection.
Solution Approach 2:
The connection device is designed with universal adaptability to fit different vehicle configurations (right-hand drive and left-hand drive). The single integrated design incorporates adjustable features that allow it to function reliably across multiple vehicle types without requiring different specialized components for each configuration.
2Ease of operation
If a standardized connection device is used, then ease of assembly on different vehicles is improved, but adaptability to specific vehicle configurations may be compromised
Solution Approach 1:
The connection device incorporates dynamic adjustable features that allow it to adapt its configuration during installation. The device can be positioned and adjusted to suit different vehicle layouts (right-hand or left-hand drive) while maintaining the same standardized assembly process, combining ease of installation with configuration flexibility.
3Ease of manufacture
If multiple parts are used in the connection device, then functional requirements are met, but production, referencing, and storage costs increase
Solution Approach 1:
The patent merges multiple functional components into a single integrated connection device that can be manufactured as one unit. This consolidation reduces the total number of parts that need to be produced, stored, and referenced, while still meeting all necessary functional requirements for connecting the operating arm to the wiper blade.
