Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing connection methods for wiper blades to wiper arms are cumbersome for operators, making it difficult to connect and disconnect the blades efficiently.
Innovation Solution
A wiper arm arrangement with a connection element that can be moved along the wiper arm's longitudinal direction, featuring a latching mechanism for secure engagement and easy access, allowing for simplified attachment and detachment of the wiper blade, and incorporating lines for washer fluid and heating energy to enhance functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional adapter connection method is used to connect the wiper blade to the wiper arm, then the connection can be secured, but the connection and disconnection process becomes cumbersome and difficult for operators
Solution Approach 1:
The connection system is divided into separate components: a connection element with latching mechanism that attaches to the wiper arm, and a separate wiper blade assembly. This segmentation allows the connection element to be independently optimized for both secure attachment and ease of operation, resolving the contradiction between reliable connection and operational simplicity
Solution Approach 2:
Instead of requiring the operator to manually manipulate complex adapter mechanisms, the design inverts the approach by using a latching mechanism that automatically secures the connection when the wiper blade is mounted. The simple mounting direction aligned with the wiper arm's longitudinal extension makes installation intuitive, while the latching mechanism handles the security aspect automatically
2Ease of operation
If the connection element is positioned closer to the end of the wiper arm for easier access, then the connection process is simplified, but the functional position may be compromised
Solution Approach 1:
The connection element is designed to be movable along the wiper arm's longitudinal direction, transitioning between an assembly position (closer to the end for easy access) and a functional position (optimized for operation). This dynamic positioning capability allows the system to satisfy both accessibility requirements during installation and stability requirements during operation, resolving the contradiction between ease of operation and functional reliability
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design simplifies the connection and disconnection process, ensures secure attachment, and allows for efficient use of washer fluid and heating to prevent freezing and noise reduction during operation.
Implementation Method 1
it has proven to be advantageous here if at least one latching element arranged on the connection element can be introduced into the at least one latching opening arranged in the end region of the wiper arm by moving the connection element into an assembly position
Implementation Method 2
when the connecting element is brought into the assembly position, the connecting element is guided on a guide on the wiper arm before the at least one latching element of the connecting element engages in the corresponding latching opening arranged in the end region of the wiper arm
Implementation Method 3
The at least one line is preferably designed for introducing washing liquid and/or heating energy into the connection element. The washer fluid and/or the heating energy can then be introduced further into the wiper blade via the connection element
Implementation Method 4
If the line for introducing heating energy into the connection element and from there further into the wiper blade is designed, heating the wiper blade can prevent the wiper blade from freezing to the windshield in winter. In addition, particularly low-noise wiping of the window can be ensured in this way
