Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If drilling mounting holes is used to attach hooks or base plates, then secure attachment is achieved, but the process becomes time-consuming, noisy, messy, and requires specialized tools
Solution Approach 1:
The patent replaces the drilling and hammering mechanical system with a simple insertion and expansion system. The anchoring element is inserted into the cable protection tube and then expanded using a simple twisting or pushing motion, eliminating the need for power drills and hammer drills.
Solution Approach 2:
The anchoring element is designed as a simple, inexpensive, single-use component that can be easily inserted and discarded after installation. It requires no specialized tools for installation and can be handled with basic hand tools or even manually.
2Reliability
If the spreading section is made fully deformable to ensure fixation, then reliable anchoring is achieved, but the structural integrity and load-bearing capacity may be compromised
Solution Approach 1:
The anchoring element is divided into distinct functional sections: a rigid shaft for structural integrity and load transmission, and a deformable spreading section with clamping elements for fixation. This segmentation allows each part to be optimized for its specific function without compromising the other.
Solution Approach 2:
Different parts of the anchoring element have different mechanical properties: the shaft maintains high strength and rigidity to bear loads, while the spreading section is designed to be elastically deformable to engage with the cable protection tube inner surface for secure fixation.
3Reliability
If the anchoring element is designed with complex expansion mechanisms to ensure secure fixation, then reliable anchoring is achieved, but manufacturing complexity and cost increase
Solution Approach 1:
The anchoring element uses elastic deformation of the clamping elements to achieve fixation. When inserted, the clamping elements are compressed radially; when expanded, they exert outward pressure on the cable protection tube inner surface, creating a secure anchor without complex mechanical mechanisms.
Solution Approach 2:
The clamping elements change their radial dimension through elastic deformation during installation. In the compressed state, they fit within the cable protection tube; in the expanded state, they exert sufficient outward pressure to create a secure anchor, achieving reliable fixation through parameter change rather than mechanical complexity.
