Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional spray systems are used to distribute cleaning agents, then the application process is simple, but the droplet size is large and spray pattern is incomplete, leading to poor sterilization effectiveness
Solution Approach 1:
The patent replaces conventional mechanical spray systems with an atomizing system that uses pressurized gas to atomize cleaning agents. This substitution enables much finer droplet distribution and complete spray patterns, directly resolving the contradiction between sterilization effectiveness and system complexity by achieving superior performance through a different physical mechanism.
Solution Approach 2:
The patent employs pressurized gas (pneumatic system) to atomize the cleaning agents instead of using conventional liquid spray mechanisms. This pneumatic approach creates fine mist patterns with complete coverage, solving the problem of large droplet sizes and incomplete spray patterns while maintaining operational simplicity.
2Reliability
If conventional spray systems are used, then the system is easy to operate, but the ability to atomize high-viscosity agents is insufficient, leading to inefficient microorganism control
Solution Approach 1:
The patent changes the physical parameters of the cleaning agent delivery system by using pressurized gas to atomize agents. This parameter change enables the system to handle high-viscosity agents effectively, converting them into fine mist for efficient microorganism control without complicating the operation.
Solution Approach 2:
By introducing a pneumatic atomizing system, the patent enables reliable atomization of high-viscosity cleaning agents that conventional systems cannot handle. The pressurized gas overcomes the viscosity issues, ensuring efficient microorganism control while keeping the system easy to operate through automated sequencing.
3Object-affected harmful factors
If conventional spray systems are used to apply cleaning agents, then the application process is straightforward, but the droplet size is large causing surface wetting and deterioration
Solution Approach 1:
The patent replaces conventional mechanical spray systems with a pneumatic atomizing system that produces fine droplets instead of large droplets. This substitution eliminates surface wetting and deterioration while achieving complete coverage, resolving the contradiction between protecting surfaces and preventing surface deterioration through advanced atomization technology.
4Reliability
If multiple cleaning agents are applied separately, then each agent can be optimized for its function, but the application time and process complexity increase
Solution Approach 1:
The patent applies cleaning agents in a predetermined sequence (short-term sterilant first, then long-term antimicrobial agent) using automated control. This preliminary sequencing ensures each agent performs its optimized function while reducing overall application time and complexity through systematic organization of the multi-agent process.
Solution Approach 2:
The patent creates a multi-functional system that can apply different cleaning agents through a single atomizing apparatus. The system integrates short-term sterilization and long-term protection functions into one unified process, maintaining agent-specific optimization while reducing application time and process complexity through consolidated equipment and automated sequencing.
