Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the density of fire-protection profiles is reduced to improve installation advantages and compressibility, then ease of operation is improved, but fire-resistance duration deteriorates
Solution Approach 1:
The patent applies composite materials by combining organic polyurethane foam with inorganic temperature-regulating fillers (such as hydroxyl-containing inorganic compounds, vermiculite, or perlite). This composite structure allows the fire-protection profile to maintain low density for ease of installation while the inorganic fillers provide enhanced fire-resistance duration through endothermic reactions and thermal insulation, directly resolving the contradiction between compressibility and fire-resistance duration
Solution Approach 2:
The patent changes the thermal parameters of the fire-protection profile by incorporating fillers with specific thermal properties (endothermic fillers that absorb heat during decomposition). These parameter changes enable the material to maintain low density while achieving improved fire-resistance duration through controlled thermal behavior during fire exposure
2Duration of action of stationary object
If temperature-regulating fillers are added to improve fire-resistance duration, then fire-resistance duration is improved, but device complexity increases
Solution Approach 1:
The temperature-regulating fillers serve multiple functions simultaneously: they provide fire-resistance duration through endothermic reactions, reduce thermal conductivity for insulation, and can act as blowing agents during foam formation. This multi-functionality allows improvement of fire-resistance duration while minimizing the need for additional separate components, thereby limiting the increase in composition complexity
