Wiper Blade Tip Cutting Control for Reliable Regeneration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wiper blades wear out over time, leading to uneven wiping and a limit on the number of regenerations, resulting in suboptimal performance when the blade rubber becomes too short.
Innovation Solution
A method and system for measuring the length of the wiper blade tip, determining if it can be cut, and cutting it when possible, with a notification system for the remaining number of regenerations, using a cutting device and control system to ensure high-quality regeneration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the tip of the blade rubber is cut multiple times to regenerate the wiper blade, then the wiping performance is restored, but the blade rubber becomes too short and cannot be regenerated further
Solution Approach 1:
The system measures the blade rubber length before cutting and determines in advance whether the blade can be regenerated. This preliminary assessment prevents attempting regeneration on blades that are already too short, ensuring that each cutting operation is performed only when it will maintain adequate blade length for future regenerations.
Solution Approach 2:
The system continuously monitors the blade rubber length and provides feedback on the remaining number of times the blade can be regenerated. This feedback mechanism allows users to know when the blade has reached its regeneration limit, preventing further cutting that would render the blade unusable.
2Duration of action of moving object
If the wiper blade is regenerated beyond the limitation, then more wiping cycles are achieved, but the desired wiping performance cannot be obtained
Solution Approach 1:
The notification means provides real-time feedback on the remaining number of regenerations possible. This feedback ensures that the blade is not regenerated beyond the point where wiping performance would deteriorate, as the system tracks and communicates the depletion of usable blade length.
Solution Approach 2:
The determination means assesses beforehand whether the blade has sufficient length to maintain desired wiping performance after cutting. This preliminary determination prevents performing regeneration operations that would result in substandard wiping performance.
3Ease of manufacture
If the tip of the blade rubber is cut, then the worn portion is removed and wiping performance is restored, but the blade rubber length decreases
Solution Approach 1:
The measurement and determination steps are performed before cutting to ensure the blade has sufficient length to withstand the upcoming regeneration operation. This preliminary check guarantees that the ease of regeneration is maintained without compromising the blade's minimum required length.

AI summary
This wiper blade restoration method is characterized by comprising: a measurement step for measuring the length of a tip of a wiper blade; a determination step for determining whether the tip of the wiper blade can be cut, on the basis of the length measured in the measurement step; and a removal step for removing at least a portion of the tip of the wiper blade if it is determined, during the determination, that the tip of the wiper blade can be cut.
