Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If potassium citrate is used as a fire extinguishing agent component, then fire extinguishing performance is improved, but property stability deteriorates due to deliquescence and moisture absorption
Solution Approach 1:
A hydrophobic coating layer is applied as an intermediary between the potassium citrate particles and the surrounding environment. This coating layer prevents direct contact between moisture and the deliquescent potassium citrate, thereby maintaining property stability while preserving fire extinguishing performance.
Solution Approach 2:
A thin hydrophobic coating film is formed on the surface of potassium citrate particles. This flexible film acts as a barrier to moisture penetration, preventing deliquescence without interfering with the fire extinguishing mechanism when activated.
2Ease of manufacture
If potassium citrate is used without coating, then manufacturing simplicity is maintained, but moisture absorption increases leading to property instability
Solution Approach 1:
A hydrophobic coating layer is applied as an intermediary between the potassium citrate particles and the surrounding environment. This coating layer prevents direct contact between moisture and the deliquescent potassium citrate, thereby maintaining property stability while preserving fire extinguishing performance.
3Stability of the object's composition
If a coating is applied to potassium citrate particles, then property stability is improved, but device complexity increases
Solution Approach 1:
A thin hydrophobic coating film is formed on the surface of potassium citrate particles. This flexible film acts as a barrier to moisture penetration, preventing deliquescence without interfering with the fire extinguishing mechanism when activated.
Solution Approach 2:
The fire extinguishing material is formulated as a composite system combining potassium citrate particles with hydrophobic coating materials. This composite structure integrates the fire extinguishing properties of potassium citrate with the moisture barrier properties of the coating, achieving both performance and stability.
