Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual cleaning personnel perform disinfection, then disinfection can be performed, but it is prone to errors, incomplete coverage, and high labor costs
Solution Approach 1:
The disinfection system is designed to operate autonomously without human intervention during the disinfection process. The controller automatically activates the pump, regulates fluid flow, and manages the timing of disinfectant distribution through multiple nozzles, enabling the system to service itself and eliminating the need for manual cleaning personnel.
Solution Approach 2:
The patent replaces the manual mechanical cleaning process with an automated electromechanical system. The controller, pump, and nozzle assembly work together to mechanically distribute the disinfectant solution, substituting human labor with an automated control system that ensures consistent and complete coverage.
2Reliability
If manual cleaning is performed, then disinfection can be carried out, but it is costly in terms of labor
Solution Approach 1:
The disinfection system is divided into distinct functional modules: a storage tank for disinfectant, a pump for fluid transfer, multiple nozzles for distribution, and a controller for coordination. This segmentation allows each component to perform its specific function efficiently, ensuring reliable disinfection while keeping the overall system manageable and not overly complex.
3Productivity
If rapid disinfection is achieved, then disease transmission risk is reduced, but automation requirements increase
Solution Approach 1:
The system maintains continuous disinfection action by coordinating multiple nozzles that operate simultaneously or in sequence, ensuring uninterrupted distribution of the disinfectant solution throughout the vehicle interior. The controller manages the continuous operation of the pump and nozzle activation to achieve rapid and thorough disinfection coverage.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system provides rapid, thorough, and cost-effective disinfection of large areas, reducing the risk of disease transmission and minimizing labor costs while ensuring compliance with disinfection schedules and fluid levels.
Implementation Method 1
A pump pumps the disinfection solution from the storage tank to the plurality of nozzles on the interior of the mass transit vehicle
Implementation Method 2
The plurality of nozzles projecting droplets of the disinfection solution into the interior of the mass transit vehicle when the system is activated

AI summary
A system for disinfecting a mass transit vehicle includes a storage tank for storing a disinfection solution. A plurality of nozzles are installed in the interior of the mass transit vehicle. The plurality of nozzles projecting droplets of the disinfection solution into the interior of the mass transit vehicle when the system is activated. A pump pumps the disinfection solution from the storage tank to the plurality of nozzles on the interior of the mass transit vehicle. A control switch initiates operation of the system. A system indicator indicates an operational status of the system. A controller controls the operation of the pump responsive to an input from the control switch. Responsive to actuation of the control switch to a first position, the controller actuates the system indicator for a first predetermined period of time and actuates the pump to pump the disinfection solution from the storage tank to the plurality of nozzles on the interior of the mass transit vehicle for a second predetermined period of time after expiration of the first predetermined period of time.
