Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle sensor cleaning systems face challenges in effectively removing foreign objects from sensors due to air leakage, which reduces the cleaning effectiveness of air or washer fluid systems, especially for small sensors in various vehicle parts.
Innovation Solution
A vehicle sensor cleaning apparatus with a compressor, air nozzles, air distributor, and air controller that detects air leakage and adjusts air intensity to ensure effective cleaning, using alternating air and washer fluid sprays to remove foreign materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If air or washer fluid is emitted to remove foreign materials from sensors, then cleaning effect is achieved, but air leakage reduces air output strength and cleaning effectiveness
Solution Approach 1:
The air controller continuously monitors the pressure value in the air tank and air hose, comparing it against reference values to detect air leakage in real-time. When leakage is detected, the system automatically compensates by adjusting the compressor operation to maintain appropriate air pressure, ensuring consistent cleaning effectiveness despite potential leakage conditions.
2Force
If air pressure is increased to improve cleaning strength, then foreign material removal improves, but air leakage becomes more significant and reduces system efficiency
Solution Approach 1:
The air controller dynamically adjusts the compressor operation based on real-time pressure monitoring. When air leakage is detected through pressure deviation, the system automatically increases compressor activity to compensate, maintaining the required air output strength for effective cleaning while optimizing energy usage by only compensating when necessary rather than continuously operating at maximum capacity.
3Productivity
If air is continuously supplied to maintain cleaning effectiveness, then foreign material removal is sustained, but air consumption increases and leakage impact is magnified
Solution Approach 1:
The system uses pressure monitoring as feedback to determine when air supplementation is necessary. Rather than continuous air supply, the controller activates the compressor only when pressure drops indicate leakage or depletion, maintaining cleaning continuity while minimizing unnecessary air consumption and reducing the impact of leakage on overall system efficiency.
