Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning apparatuses for vehicle viewing areas fail to optimize cleaning processes under varying ambient conditions, leading to incomplete cleaning and increased fluid usage, which affects the reliability of environment sensors and increases costs.

Engineering Contradiction Analysis
1Ease of operation
If manual or simple automatic cleaning is used, then the cleaning process is simple to operate, but the cleaning completeness deteriorates under varying ambient conditions
Solution Approach 1:
The cleaning apparatus dynamically adapts the cleaning process by selecting different cleaning profiles (e.g., aggressive vs. gentle cleaning) based on real-time ambient conditions detected by sensors. This allows the system to optimize cleaning effectiveness for each specific situation while maintaining simple operation for the user.
Solution Approach 2:
The system uses sensors to detect ambient conditions (temperature, humidity, contamination level) and provides feedback to the control unit, which then selects the appropriate cleaning profile. This closed-loop feedback mechanism ensures reliable cleaning results without requiring complex user intervention.
2Reliability
If aggressive cleaning is applied, then cleaning effectiveness is improved, but fluid consumption increases
Solution Approach 1:
The system changes cleaning parameters (fluid amount, pressure, duration) based on the selected cleaning profile and detected ambient conditions. For lightly contaminated surfaces, a gentle profile with minimal fluid is used, while heavily contaminated surfaces receive aggressive cleaning with appropriate fluid allocation, optimizing the balance between effectiveness and consumption.
3Device complexity
If cleaning is not optimized for ambient conditions, then device complexity is reduced, but cleaning quality deteriorates
Solution Approach 1:
The system incorporates multiple pre-programmed cleaning profiles that can be dynamically selected based on ambient conditions detected by sensors. This approach achieves adaptive, high-quality cleaning without requiring overly complex real-time calculation and control algorithms, maintaining a reasonable balance between system complexity and cleaning quality.
4Reliability
If multiple cleaning cycles are performed, then cleaning completeness is improved, but time consumption increases
Solution Approach 1:
The system dynamically determines the number and duration of cleaning cycles based on the selected cleaning profile and detected contamination level. The control unit optimizes the cleaning process by applying the appropriate profile that achieves complete cleaning in the minimum necessary time, avoiding unnecessary repeated cycles.
