Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional sterilization methods using aqueous hydrogen peroxide or chemicals are used, then sterilization can be achieved, but chemical residues are left on the sterilized surfaces
Solution Approach 1:
The patent replaces chemical sterilization methods (aqueous hydrogen peroxide or chemical agents) with a plasma-based sterilization system. The plasma generation unit creates plasma in a process gas (oxygen or air) and irradiates it onto the sterilization target, substituting chemical substances with plasma energy to achieve sterilization without leaving chemical residues.
Solution Approach 2:
The patent changes the sterilization mechanism from chemical composition to physical energy state. By controlling plasma parameters (power, gas flow rate, treatment time) and adjusting the plasma generation conditions, the system achieves effective sterilization through physical plasma irradiation rather than chemical contact, eliminating residue problems.
2Ease of manufacture
If plasma jet is generated by atmospheric electric discharge in process gas containing oxygen, then sterilization can be carried out, but the sterilization effects are insufficient compared to conventional methods
Solution Approach 1:
The patent utilizes the strong oxidizing properties of plasma to enhance sterilization effects. The plasma generation unit creates reactive oxygen species and energetic particles that aggressively attack and destroy microorganisms on the sterilization target surface, providing more effective sterilization than conventional plasma jet methods while maintaining process simplicity.
Solution Approach 2:
The patent employs periodic or controlled plasma irradiation cycles. The plasma generation unit operates in a controlled manner with adjustable power and duration, allowing optimal sterilization effects to be achieved through controlled periodic action rather than continuous exposure, improving both effectiveness and energy efficiency.
3Reliability
If metal nozzles are used for plasma jet irradiation, then durability and corrosion resistance are improved, but the diffusion control of reactive oxygen is insufficient
Solution Approach 1:
The patent introduces a shielding structure as an intermediary element between the plasma source and the sterilization target. This shielding structure (made of resin or non-metal) controls and directs the diffusion of reactive oxygen and plasma particles onto the target surface, improving precision of sterilization while the metal nozzle maintains its durability function for plasma generation.
