Pantograph Wiper Connecting Member for Translational Adaptor Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pantographic wiper systems lack a mechanism for translational assembly and disassembly of the adaptor and wiper blade, which complicates connections and affects aerodynamics and liquid supply for cleaning.
Innovation Solution
A connecting member with a 'U-shape' section and bended claws is introduced, allowing for translational assembly of the adaptor between the first and second pivot links, enhancing aerodynamics and enabling liquid connection for cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a traditional rigid connection is used between the adaptor and wiper blade, then structural strength is maintained, but assembly and disassembly operations become complex and time-consuming
Solution Approach 1:
The connection device is segmented into multiple functional elements: guide claws for alignment, a locking mechanism with movable locking elements, and release buttons. This segmentation allows the connection process to be divided into simple sequential steps (alignment → engagement → locking) that are easy to perform while maintaining strong connection through the distributed locking elements
Solution Approach 2:
The connection device acts as an intermediary component between the adaptor and wiper blade, providing a specialized interface that simplifies the connection operation. The guide claws and locking elements serve as intermediary mechanisms that mediate the assembly process, making it intuitive and easy to perform while ensuring secure connection
2Object-affected harmful factors
If the connecting member has a compact design, then aerodynamics is improved, but the range of motion for assembly is reduced
Solution Approach 1:
The connection device incorporates dynamic elements including movable guide claws that can flex during assembly, and a locking mechanism with movable locking elements that engage and disengage. This dynamic design allows the connection device to adapt its shape during assembly operations, providing sufficient range of motion while maintaining a compact aerodynamic profile during wiper operation
3Object-affected harmful factors
If the connecting device is positioned between the pivot links, then aerodynamics and liquid supply are improved, but the device complexity increases
Solution Approach 1:
The connection device positioned between the pivot links serves multiple functions simultaneously: it provides mechanical connection and locking, guides alignment during assembly, supplies cleaning liquid through integrated channels, and maintains aerodynamic efficiency. This multi-functionality consolidates several required features into a single integrated component, managing complexity through functional integration rather than adding separate components
