Wiper Arm Service Position Triggered by Blade Label Scanning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wiper systems for motor vehicles require manual movement of the wiper arm to a service position for blade replacement, which can be inconvenient and requires the ignition to be turned on.
Innovation Solution
A computer-implemented method and device that allows the wiper arm to be moved to a service position automatically upon scanning a QR code or label on the wiper blade packaging, enabling blade replacement without needing to turn on the ignition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the wiper arm is moved manually to a service position for blade replacement, then the installation can be performed, but the operation becomes inconvenient and requires the ignition to be turned on
Solution Approach 1:
The system automatically moves the wiper arm to the service position in advance before the user needs to install the blade. The control unit receives a replacement signal (e.g., via QR code scan) and autonomously positions the wiper arm, eliminating the need for manual intervention and ignition activation.
Solution Approach 2:
The wiper system performs self-positioning to the service position automatically upon receiving a replacement signal. The system serves itself by autonomously navigating to the required position without external manual control, reducing user effort and system complexity.
2Ease of operation
If the ignition must be turned on to move the wiper arm to service position, then the system can be controlled, but the operation becomes less convenient for users
Solution Approach 1:
The wiper arm is positioned to the service position as a preliminary automatic action triggered by a replacement signal. This pre-positioning occurs without requiring the ignition to be on, allowing users to perform blade replacement at any time without energy consumption from the vehicle's electrical system.
Solution Approach 2:
The system uses periodic or event-triggered action rather than continuous operation. The wiper arm moves to the service position only when a replacement signal is detected (e.g., QR code scanned), rather than requiring continuous ignition power, thus reducing overall energy consumption.
3Reliability
If a label scanning system is implemented to verify wiper blade compatibility, then installation safety is improved, but the device complexity increases
Solution Approach 1:
The mechanical/physical verification process is replaced with an optical/electronic scanning system. Instead of manual checking of compatibility, a sensor or mobile device scans a label (e.g., QR code) to automatically verify wiper blade compatibility, improving reliability while keeping the system relatively simple through substitution of verification methods.
Solution Approach 2:
A label with machine-readable information serves as an intermediary between the wiper blade and the verification system. The label encodes compatibility information that can be scanned and verified automatically, simplifying the interaction between the user, the wiper blade, and the control system while ensuring reliability.
Data Source
AI summary
Computer-implemented method for installing a wiper blade on a wiper arm of a motor vehicle, wherein the wiper arm is moved to a service position for installing the wiper blade. It is suggested that a label applied at least indirectly to the wiper blade and/or to the wiper blade package be scanned and that the wiper arm be moved to the service position as a function of the scanned label. Furthermore, a device and a computer program are specified for the computer-implemented method. In addition, a method is specified for mounting a wiper blade on a wiper arm.
