Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a metal wire is added to the polymer tube to improve installation stability, then the preparation can be stably held, but production cost and filling cost increase
Solution Approach 1:
The invention extracts and removes the metal wire component from the pheromone preparation structure, relying solely on the polymer tube's own elastic properties to provide installation stability. The polymer tube is designed with specific wall thickness (0.2-1.0mm) and diameter (1.0-5.0mm) to generate sufficient repelling force without any metal wire reinforcement, thereby eliminating the associated costs while maintaining reliability.
Solution Approach 2:
The polymer tube serves itself by utilizing its own elastic deformation characteristics to provide the repelling force needed for stable installation. When the tube is bent into a loop and pressed against a branch, it generates elastic repelling force that secures the preparation in place, making the structure self-supporting without requiring additional metal wire components.
2Stability of the object's composition
If a metal wire is added to the polymer tube to improve shape retention, then the preparation maintains its shape, but installation time increases due to twisting requirements
Solution Approach 1:
The polymer tube is designed to dynamically deform elastically during installation and then maintain its shaped configuration through elastic memory. The tube can be temporarily bent into the desired loop shape during installation, and its elastic properties ensure it retains this shape afterward without requiring time-consuming twisting operations with metal wires.
3Ease of operation
If the polymer tube is bent into a loop shape for easy installation, then installation becomes simpler, but the tube may fall off due to insufficient repelling force
Solution Approach 1:
The invention optimizes the physical parameters of the polymer tube, specifically the wall thickness (0.2-1.0mm) and outer diameter (1.0-5.0mm), to achieve the optimal balance between ease of installation and retention stability. These parameter ranges ensure the tube has sufficient elastic repelling force to maintain stable attachment on branches while remaining easy to install by simple bending into loop shapes.
