Innovation Solution
An air purifying sterilizer module incorporating a filter unit, photocatalyst unit with alloy coated metal foam, deodorizing catalyst unit, and ultraviolet lamp, where the alloy coated metal foam is prepared by coating a binder and alloy powder on metal foam, enhancing catalytic performance and adhesion, and including a low-temperature deodorizing filter for improved pollutant removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple dust collection and deodorization type is used, then the device complexity is reduced, but the catalytic performance and carbon monoxide removal function are insufficient
Solution Approach 1:
The patent uses composite materials by combining metal foam with catalyst coatings (precious metals or transition metals) to create a hybrid structure that leverages the high surface area of metal foam and the catalytic activity of the coated materials, achieving both simple device design and high catalytic performance for CO removal
Solution Approach 2:
The patent employs porous metal foam materials with high porosity (greater than 90%) to provide large surface area for catalyst attachment while maintaining low pressure loss and efficient gas flow, enabling effective catalytic conversion without complex device structures
2Stress or pressure
If metal foam with smooth surface is used, then the pressure loss is reduced, but the catalyst coating is difficult and catalyst detachment occurs frequently
Solution Approach 1:
The patent applies local quality by treating the metal foam surface with specific coatings or roughening treatments in localized areas to enhance catalyst adhesion, while maintaining the overall smooth porous structure for low pressure loss, creating different surface properties in different locations
3Ease of manufacture
If catalyst is coated on smooth metal foam surface, then the manufacturing process is simplified, but the catalytic reaction is not maximized and performance deteriorates over time
Solution Approach 1:
The patent utilizes porous metal foam structures that inherently provide large surface area without complex manufacturing, allowing simple catalyst coating processes while maximizing catalytic reaction efficiency through the high surface-to-volume ratio and optimized pore structures
4Ease of manufacture
If catalyst replacement is required frequently, then the initial manufacturing cost is reduced, but the management difficulty and operational costs increase
Solution Approach 1:
The patent implements self-service by designing the catalyst system to be self-sustaining with enhanced durability through improved adhesion mechanisms and stable catalyst supports, eliminating the need for frequent manual replacement and allowing the system to maintain performance autonomously over extended periods
