Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a liquefied gas cylinder is used as the gas source, then the carrier gas can be supplied, but the apparatus becomes complex, heavy, and requires a power supply for heating
Solution Approach 1:
The invention extracts and eliminates the heater component from the system by switching from liquefied gas cylinders to compressed gas cylinders. This removes the need for heating mechanisms and power supply, significantly simplifying the apparatus configuration while maintaining the essential function of carrier gas supply
Solution Approach 2:
The invention changes the physical state parameter of the gas source from liquefied to compressed state. This parameter change eliminates the need for heating and phase change processes, thereby reducing device complexity and removing the requirement for power supply while ensuring reliable carrier gas delivery
2Reliability
If a liquefied gas cylinder is used as the gas source, then the carrier gas can be supplied, but the apparatus weight increases
Solution Approach 1:
The invention removes the heater and associated power supply components by extracting them from the system architecture. This extraction directly reduces the apparatus weight while maintaining the core function of supplying carrier gas through compressed gas cylinders
3Reliability
If a liquefied gas cylinder is used as the gas source, then the carrier gas can be supplied, but the apparatus requires a power supply
Solution Approach 1:
The invention extracts and eliminates the heater component that requires power supply. By using compressed gas cylinders instead of liquefied gas cylinders, the system no longer needs heating mechanisms, thereby removing the power supply requirement while ensuring reliable carrier gas supply through pressure-driven flow
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 apparatus achieves efficient sterilization and disinfection with a simplified structure, reduced weight, and improved mobility, enabling easy movement and use in multiple locations without the need for a power supply, while maintaining effective chemical distribution and evaporation characteristics.
Implementation Method 1
a pressure reducing valve, attached near an outlet of the gas cylinder, for decompressing the gas discharged from the outlet to a predetermined pressure
Implementation Method 2
sprays the chemical into a target space by the function of the carrier gas injected from the end nozzle of the spray gun
Implementation Method 3
the chemical will evaporate rapidly after adhering to the wall surface, floor surface and the like in the target space without remaining for a long time

AI summary
An apparatus for sterilizing and disinfecting a target space by spraying a chemical including alcohol includes a spray gun 4 to which a chemical container 7 containing a sterilizing and disinfecting chemical including alcohol is attachable, a gas cylinder 1 filled with a compressed carrier gas that does not react with alcohol, and a pressure reducing valve 2 for decompressing the carrier gas discharged in a vaporized state from the gas cylinder 1 to a predetermined pressure, and is constructed so that the pressure reducing valve 2 and the spray gun 4 are directly connected with a gas hose 3 and mounted on a common truck 5. The sterilizing and disinfecting apparatus can operate with a simple structure requiring no power supply, and is much lighter in weight compared to conventional apparatuses.
