Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple containers are used to provide multiple attractant components, then the attractant composition can effectively attract bloodsucking arthropods and fruit flies, but the handling complexity and device complexity increase
Solution Approach 1:
The patent combines multiple attractant components (lactic acid, carbon dioxide, water) and the buffer system into a single integrated porous substrate. This merging eliminates the need for multiple separate containers while maintaining the effectiveness of attracting bloodsucking arthropods and fruit flies, directly resolving the contradiction between attraction reliability and device complexity
Solution Approach 2:
The patent uses a composite porous substrate that integrates multiple functional components: the buffer system, attractant components, and porous structure all combined in one material. This composite approach allows the substrate to provide multiple attractant functions simultaneously while maintaining simple handling, eliminating the need for multiple separate containers
2Reliability
If multiple containers are used to provide multiple attractant components, then the attractant composition can effectively attract bloodsucking arthropods and fruit flies, but the ease of operation decreases
Solution Approach 1:
By merging all attractant components and the buffer system into a single porous substrate, the patent eliminates the need for users to handle multiple containers. The unified structure maintains effective attraction while dramatically improving ease of operation, as users only need to handle one integrated component
Solution Approach 2:
The porous substrate is designed to automatically release attractant components through its porous structure without requiring external intervention. The buffer system and attractant components work together autonomously to provide sustained attraction, eliminating the need for complex user manipulation of multiple separate containers
3Duration of action of moving object
If attractants are embedded in porous substrate and slowly released, then the duration of action increases, but the manufacturing process complexity increases
Solution Approach 1:
The patent utilizes the inherent porous structure of the substrate to achieve slow release of attractant components. The porous material naturally allows controlled diffusion and evaporation of attractants over extended periods, providing long duration of action without requiring complex manufacturing processes. The porous structure itself serves as the release mechanism
Solution Approach 2:
The buffer system is pre-integrated into the porous substrate during manufacturing, preparing the attractant components for controlled release. This preliminary integration ensures that when the substrate is deployed, the attractants are already positioned for optimal slow release, extending duration of action while keeping the manufacturing process straightforward
