Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing air purifying products are used, then VOC reduction is achieved initially, but they become inactive as they fill with impurities and lose efficacy over time
Solution Approach 1:
The patent employs diatomic frustule particles with porous structures that provide continuous surface area for VOC adsorption. The porous nature allows the particles to maintain active sites for contaminant capture over extended periods without becoming saturated, thereby achieving lasting VOC reduction efficacy.
Solution Approach 2:
The invention creates a composite system combining diatomic frustule particles with a carrier agent formulation. This composite approach integrates the high surface area and porosity of the frustule particles with the protective and delivery properties of the carrier, resulting in a stable, long-lasting air purifying coating that maintains efficacy over time.
2Reliability
If diatomic frustule particle dispersion is added to carrier agent, then VOC reduction capability is enhanced, but product complexity increases
Solution Approach 1:
The carrier agent acts as an intermediary medium that facilitates the integration of diatomic frustule particles into a usable coating formulation. The carrier agent provides a stable matrix that holds the particles, ensures proper dispersion, and delivers the air purifying function while maintaining product usability and limiting complexity.
Solution Approach 2:
The patent optimizes parameters such as particle size (1-35 microns), particle concentration (0.1-15 weight percent), and carrier agent composition to achieve effective VOC reduction while maintaining product simplicity. By carefully controlling these parameters, the invention enhances functionality without proportionally increasing complexity.
3Reliability
If diatomic frustule particles are used, then air purifying function is provided, but particle aggregation may occur reducing effectiveness
Solution Approach 1:
The carrier agent serves as a stabilizing intermediary that prevents diatomic frustule particles from aggregating. Through proper formulation with surfactants and dispersants within the carrier, individual particles remain separated and distributed uniformly throughout the coating, maintaining air purifying function and preventing effectiveness loss due to aggregation.
