Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If conventional disinfectant compositions are used to disinfect surfaces, then pathogen destruction is achieved, but the efficacy period is short and the composition lacks overall efficacy
Solution Approach 1:
The patent combines silver particles with hydrogen peroxide to create a composite disinfectant composition. This composite approach leverages the antimicrobial properties of silver particles and the oxidizing action of hydrogen peroxide to achieve both high overall efficacy and extended duration of action, resolving the contradiction between short efficacy period and insufficient overall efficacy.
Solution Approach 2:
The patent specifies particular concentrations of silver particles (10 ppb to 60 ppm) and hydrogen peroxide (0.1% to 5%) to optimize the composition's performance. By carefully controlling these parameters, the composition achieves sustained pathogen destruction capability over extended periods while maintaining high overall efficacy.
2Reliability
If conventional disinfectant compositions are used to disinfect surfaces, then disinfection is achieved, but the compositions are toxic to humans and animals
Solution Approach 1:
The patent uses low concentrations of silver particles (10 ppb to 60 ppm) and hydrogen peroxide (0.1% to 5%) to achieve effective disinfection while minimizing toxicity. This parameter optimization allows the composition to maintain pathogen destruction capability while being safe for humans and animals.
Solution Approach 2:
The patent employs hydrogen peroxide as a strong oxidant that decomposes into water and oxygen, providing effective disinfection without leaving toxic residues. This oxidizing mechanism achieves reliable pathogen destruction while being inherently safer for human and animal contact compared to conventional toxic disinfectants.
3Reliability
If conventional disinfectant compositions are used to disinfect surfaces, then disinfection is achieved, but the compositions are harmful to the environment
Solution Approach 1:
Hydrogen peroxide serves as an environmentally benign strong oxidant that breaks down into water and oxygen, eliminating harmful environmental residues while maintaining effective disinfection capability. This resolves the contradiction between achieving reliable disinfection and avoiding environmental harm.
Solution Approach 2:
The patent optimizes silver particle concentration to 10 ppb to 60 ppm, a range that provides effective disinfection while minimizing environmental accumulation and ecological impact, thus achieving both disinfection reliability and environmental safety.
4Reliability
If conventional disinfectant compositions are used to disinfect surfaces, then disinfection is achieved, but the treated surface is damaged (staining, corrosive)
Solution Approach 1:
The patent uses low concentrations of silver particles (10 ppb to 60 ppm) and hydrogen peroxide (0.1% to 5%) that are effective for disinfection but gentle enough to avoid surface damage. This parameter control prevents staining and corrosion while maintaining pathogen destruction capability.
Solution Approach 2:
Hydrogen peroxide provides effective oxidation-based disinfection without the harsh corrosive effects of conventional disinfectants. Its decomposition into water and oxygen ensures surface safety while maintaining high disinfection reliability.
5Reliability
If conventional disinfectant compositions are used to disinfect surfaces, then disinfection is achieved, but the compositions are dangerous or hazardous to handle
Solution Approach 1:
Hydrogen peroxide replaces hazardous conventional disinfectants with a safer oxidizing agent that is less flammable and volatile. This provides effective disinfection while significantly improving handling safety and reducing operational hazards.
Solution Approach 2:
The patent formulates the composition with low concentrations of hydrogen peroxide (0.1% to 5%) and silver particles (10 ppb to 60 ppm), creating a composition that is effective for disinfection but safe for handling, thus resolving the contradiction between disinfection reliability and operational safety.
