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 on trees, but the production cost and filling cost increase significantly
Solution Approach 1:
The invention removes the metal wire component from the preparation structure, extracting the harmful and costly element while maintaining installation stability through the polymer tube's own elastic properties and loop configuration
Solution Approach 2:
The invention replaces expensive metal wires with a disposable polymer tube structure that can be easily manufactured and installed, accepting that the polymer itself serves as the complete preparation without needing additional supportive components
2Reliability
If a metal wire is added to the polymer tube to improve installation stability, then the preparation can be stably held on trees, but the installation process becomes time-consuming due to twisting operations
Solution Approach 1:
The invention removes the metal wire component that requires twisting operations, eliminating the time-consuming installation step while maintaining stability through the polymer tube's inherent elastic recovery properties
Solution Approach 2:
The polymer tube's elastic properties enable it to self-adjust and self-secure on the tree branch without requiring manual twisting or additional fastening operations, making the installation process simpler and faster
3Reliability
If a metal wire is added to the polymer tube to improve installation stability, then the preparation can be stably held on trees, but the preparation becomes troublesome to remove after use
Solution Approach 1:
The invention removes the metal wire that creates removal difficulties, allowing the entire preparation to be easily detached and removed from the tree as a single polymer component
Solution Approach 2:
The polymer tube's flexibility and lack of rigid components enable it to be easily manipulated and removed by hand without requiring tools or complex detachment procedures
4Reliability
If a metal wire is added to the polymer tube to improve installation stability, then the preparation can be stably held on trees, but the pruning blade may be damaged during pruning operations
Solution Approach 1:
The invention removes the metal wire component that poses a risk to pruning blades, eliminating the harmful factor while maintaining preparation stability through the polymer tube's elastic properties
Solution Approach 2:
The invention uses a disposable polymer-based preparation that eliminates metal components, protecting pruning equipment from damage while the preparation serves its intended short-term function
5Ease of operation
If the polymer tube ends are joined together to form a loop for easy installation, then the preparation can be hung on trees without metal wires, but the tube may be fused, adhered or have gaps that cause installation limitations or detachment
Solution Approach 1:
The invention forms the polymer tube into a circular loop shape, utilizing the curved geometry to provide stable placement on tree branches while maintaining the tube's integrity and pheromone release function
Solution Approach 2:
The invention carefully controls the tube's physical parameters including curvature radius (5-20mm) and circularity to ensure the loop maintains stability on branches without fusing or creating gaps that would cause detachment
