Wiper Blade Fluid-Power Interface for Flat Sealed Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wiper blade designs face challenges in achieving a flatter design due to the need to arrange power and cleaning fluid connections one above the other, leading to potential leakage and incomplete sealing, and assembly complexity.
Innovation Solution
The wiper blade and wiper arm system separates the connections for cleaning fluid and power, allowing them to be positioned at different points with a lower overall height, using an elastic hose line and separate adapters for fluid and power supply, ensuring easy assembly and improved sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If power and cleaning fluid connections are arranged one above the other in a narrow wiper blade adapter, then the overall height is reduced, but the risk of leakage and incomplete sealing increases
Solution Approach 1:
The patent divides the connection area into separate zones: power connections are positioned at the upper end of the wiper blade adapter while cleaning fluid connections are positioned at the lower end, creating spatial separation that prevents fluid leakage from affecting electrical connections and improves sealing reliability
2Adaptability or versatility
If multiple connection points for power and cleaning fluid are provided on the wiper blade adapter, then functional requirements are met, but the width of the wiper blade adapter increases
Solution Approach 1:
The patent transitions from arranging connections horizontally (width direction) to arranging them vertically (height direction), with power connections at the upper end and cleaning fluid connections at the lower end, thereby maintaining connection functionality while minimizing width increase
3Device complexity
If the wiper blade adapter integrates both power and cleaning fluid connections, then a compact design is achieved, but assembly complexity increases due to multiple connection points
Solution Approach 1:
The patent segments the connection system into distinct power connection components and cleaning fluid connection components positioned at different locations (upper and lower ends), which simplifies the assembly process by allowing independent installation and connection of each type without interference

AI summary
The invention relates to a wiper blade with a wiper arm which can be releasably connected together by means of a wiper blade adapter (3) arranged on the wiper blade (1). A supply line for a cleaning fluid (8) can be connected to the wiper arm (2) via terminal connections on the wiper blade adapter (3), and a flow supply connection is releasably arranged between the wiper blade (1) and the wiper arm (2), wherein the wiper blade adapter (3) allows a rotational movement between the wiper blade (1) and the wiper arm (2). According to the invention, a flow supply adapter (12) is arranged on the wiper blade (1) separately from the wiper blade adapter (3) and at a distance thereto, said flow supply adapter having contact surfaces (13) for contacting the wiper arm contact surfaces (18) in a physical or sliding manner, wherein the contact surfaces (13) are oriented so as to slide on the wiper arm contact surfaces (18) in the event of a rotation between the wiper blade (1) and the wiper arm (2).
