Vehicle Compartment Cleaning via Thermal Desorption and Ventilation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for cleaning vehicle passenger compartments, especially those with high occupancy rates, are costly, labor-intensive, and require vehicles to be moved to cleaning stations, with existing solutions either failing to address impurity removal from surfaces or being inefficient in planning and execution.
Innovation Solution
A self-contained cleaning system integrated within the vehicle that includes sensors to measure air quality, heating elements to desorb impurities at temperatures above 40°C, and a ventilation system to evacuate them, allowing for internal and efficient purification without external labor or station visits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If external cleaning devices are used to clean the passenger compartment, then cleaning effectiveness is improved, but operational cost and time loss increase due to vehicle movement and labor requirements
Solution Approach 1:
The cleaning system is integrated within the vehicle itself, enabling the vehicle to clean its own passenger compartment without external assistance. The system includes heating elements, ventilation members, and control devices that work autonomously to detect and eliminate impurities, eliminating the need for vehicle movement to external cleaning stations and reducing time loss.
Solution Approach 2:
The cleaning function is extracted from external service operations and integrated directly into the vehicle's internal systems. By incorporating heating members, ventilation members, and control devices within the vehicle structure, the cleaning capability becomes an intrinsic function of the vehicle rather than an external service requirement.
2Reliability
If external cleaning services are utilized, then cleaning quality is improved, but operational complexity increases due to scheduling and coordination requirements
Solution Approach 1:
The autonomous cleaning system eliminates the need for external service coordination by performing cleaning operations independently. The control device automatically monitors impurity levels and activates heating and ventilation systems as needed, removing scheduling and coordination complexities from the operational workflow.
Solution Approach 2:
The system incorporates a control device that continuously monitors the passenger compartment environment and provides feedback to automatically regulate cleaning operations. This closed-loop control eliminates the need for manual scheduling and coordination by making cleaning decisions based on real-time environmental conditions.
3Object-affected harmful factors
If cleaning is performed frequently to maintain high cleanliness standards, then passenger comfort is improved, but energy consumption and operational costs increase
Solution Approach 1:
The control device monitors impurity levels in the passenger compartment and activates heating and ventilation systems only when contamination thresholds are exceeded. This demand-responsive operation maintains high cleanliness standards and passenger comfort while avoiding unnecessary energy consumption during clean periods.
Solution Approach 2:
The system dynamically adjusts cleaning operations based on measured impurity levels, transitioning from fixed-schedule frequent cleaning to condition-based cleaning. This parameter change in operational strategy maintains comfort standards while optimizing energy consumption by activating cleaning functions only when actually needed.
