Wiper Blade Replacement Indicator Using Elapsed-Time Light Alerts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wiper blades in vehicles often deteriorate over time, leading to reduced wiping performance and potentially hazardous driving conditions due to incomplete visibility, as users typically replace them only after noticeable noise or performance degradation, rather than at optimal intervals.
Innovation Solution
A wiper blade with an integrated indicator that uses a controller and notifier to generate light signals based on accumulated time since installation, regardless of operational usage, to notify users of the need for replacement, ensuring timely replacement and maintaining optimal performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users replace wiper blades based on operational signs (noise, performance degradation), then replacement is performed after actual wear has occurred, but this leads to delayed replacement and compromised safety
Solution Approach 1:
The indicator device performs preliminary action by notifying users of the replacement timing before actual wear symptoms appear. The controller calculates elapsed time since installation and triggers the notifier to alert users in advance, enabling proactive replacement scheduling rather than reactive replacement based on performance degradation.
2Measurement precision
If an indicator system is implemented to track elapsed time, then replacement timing is accurately monitored, but device complexity increases
Solution Approach 1:
The indicator device utilizes the vehicle's existing power supply system and integrates with the wiper blade's installation structure. The controller leverages the vehicle's electrical system for power, and the notifier can utilize existing vehicle display systems or lighting, thereby reducing the need for separate dedicated components and minimizing overall system complexity.
Solution Approach 2:
The indicator device is self-contained with the wiper blade assembly, requiring minimal external infrastructure. The controller automatically tracks elapsed time and triggers notifications without requiring user intervention for timing calculations, making the system autonomous and reducing operational complexity.
3Measurement precision
If the indicator system continuously monitors time, then replacement timing is accurately tracked, but energy consumption increases
Solution Approach 1:
The controller operates in a periodic manner, calculating elapsed time at intervals rather than continuously. The notifier is activated only at specific moments - when the predetermined replacement time is reached or at scheduled intervals - rather than operating continuously, thereby significantly reducing energy consumption while maintaining accurate time tracking capability.

AI summary
The present disclosure relates to an indicator for a wiper blade and a wiper blade. The indicator is a device for a wiper blade detachably provided on a wiper arm for cleaning a windshield, including: a main body provided on the wiper blade or the wiper arm; a notifier provided in the main body and configured to generate a light signal that is identifiable with naked eyes; and a controller configured to control an operation of the notifier, wherein the controller is configured to count the accumulated time from a start time at which an external operation is input regardless of whether the wiper blade operates so as to operate the notifier when the accumulated time reaches a predetermine time.
