Perpendicular Wiper Blade Adapter Fluid Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wiper blade technologies face challenges in providing a simple and reliable connection to the wiper arm, particularly in preventing fluid leakage and damage during car washes, while minimizing the length of the vehicle-side supply line and ensuring a secure fluid connection.
Innovation Solution
The wiper blade adapter is designed with swivellable adapter elements on both the wiper blade and wiper arm sides, connected via a hose connection, featuring a fluid connecting piece attachment that runs perpendicularly to the wiper blade axis, and an additional detent connection to secure the fluid link, with the connecting piece overlapping the wiper arm covering to prevent damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the wiper blade adapter is connected to the wiper arm adapter in a direction parallel to the wiper blade longitudinal axis, then the fluid connection can be produced simultaneously with the mechanical connection, but the connection complexity increases and the operator cannot easily grasp the wiper blade longitudinal axis to perform the connection
Solution Approach 1:
The patent inverts the conventional connection direction from parallel to perpendicular relative to the wiper blade longitudinal axis. This allows the operator to easily grasp the wiper blade and perform the connection by simply pushing it onto the wiper arm adapter, significantly improving ease of operation while maintaining simultaneous production of mechanical and fluid connections
2Reliability
If the connecting piece attachment is arranged on the side facing away from the wiper arm, then the fluid connection is established, but the supply line length increases and the connecting point is exposed to damage during car washes
Solution Approach 1:
The patent positions the connecting piece attachment on the side facing the wiper arm, allowing the wiper arm or its covering to overlap and protect the connecting point. This nesting arrangement shields the fluid connection from external damage during car washes while maintaining reliable fluid connection, and simultaneously minimizes the supply line length
3Ease of manufacture
If the connecting piece attachment is not protected by the wiper arm covering, then the connection structure is simpler, but the fluid connection is vulnerable to damage during car washes
Solution Approach 1:
The patent utilizes the existing wiper arm covering to provide protective overlap for the connecting piece attachment before any damage can occur. This beforehand cushioning approach leverages the existing structure to protect the fluid connection from car wash damage without adding complex protective mechanisms, maintaining manufacturing simplicity while improving durability
