Method of decontaminating a vehicle interior
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for decontaminating motor vehicle passenger compartments are cumbersome and require the vehicle to be empty, as they use toxic substances and do not effectively address the source of microbial pollution, leading to bad odors and discomfort.
Innovation Solution
An automated method that detects volatile organic compounds of biological origin using infrared detectors or mass spectrometers, compares concentrations to a pollution threshold, and initiates decontamination only when the vehicle is unoccupied, using a combination of ventilation, essential oils, ionizers, and chemical treatments while ensuring occupant safety through warning messages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If toxic substances are used for decontamination, then decontamination effectiveness is improved, but passenger safety deteriorates
Solution Approach 1:
The system performs occupant detection before initiating decontamination. The control unit checks whether the vehicle is occupied via sensors (weight sensors, presence detectors) and only activates the decontamination process when no occupants are detected, preventing toxic substance exposure to passengers while maintaining effective decontamination when the vehicle is unoccupied
Solution Approach 2:
The control unit acts as an intermediary between the decontamination system and occupants. It monitors vehicle occupancy status and mediates the decontamination process by enabling it only when safe (vehicle unoccupied), thus protecting passengers from toxic substances while allowing effective decontamination to proceed
2Reliability
If manual decontamination process is used, then decontamination can be performed, but ease of operation deteriorates
Solution Approach 1:
The decontamination system operates autonomously without requiring manual intervention. The control unit automatically detects VOC concentrations via sensors, determines vehicle occupancy status, and activates the appropriate decontamination process (chemical treatment when unoccupied, ventilation when occupied) based on real-time conditions, making the system self-regulating and convenient for users
Solution Approach 2:
The system continuously monitors VOC concentrations and occupancy status through sensors and feedback loops. The control unit receives real-time data from VOC detectors and occupancy sensors, adjusts the decontamination process accordingly, and maintains automatic operation based on changing conditions, eliminating the need for manual operation while ensuring effective decontamination
3Loss of time
If decontamination is performed when vehicle is occupied, then decontamination timeliness is improved, but passenger safety deteriorates
Solution Approach 1:
The decontamination system dynamically adjusts its operation based on real-time occupancy detection. When occupants are detected, the system switches to safe mode (ventilation only). When no occupants are present, it activates full decontamination mode (chemical treatment). This dynamic adaptation allows timely decontamination when safe and prevents harmful exposure when occupants are present
Solution Approach 2:
The system changes operational parameters based on occupancy status. The control unit modifies the decontamination intensity, chemical substance deployment, and ventilation rate according to whether occupants are detected. This parameter adjustment enables effective decontamination timing while preventing toxic substance exposure to passengers

AI summary
Method of decontaminating an interior wall in order to decontaminate a motor vehicle interior comprising a step (S01) of detecting a concentration of pollutant compounds in the interior, a step (S02) of comparing the detected concentration against a pollution threshold, an occupant-detection step (S04) to detect whether an occupant is present in the interior if the detected concentration is above the pollution threshold, and a step (S06) of automatically decontaminating the interior if it is detected that the vehicle is unoccupied.
