Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a band is used for coupling the upper pipe and the lower pipe, then the cable protection pipe can be assembled, but the coupling force is weak and the pipes are easily separated
Solution Approach 1:
The coupling function is merged into the pipe structure itself through integrated coupling protrusions and recesses formed directly on the upper and lower pipe bodies. This eliminates the need for separate coupling devices like bands, achieving both easy assembly and strong reliable coupling through the inherent structural design of the pipes.
Solution Approach 2:
The pipes are designed with self-coupling capabilities through complementary geometric features (protrusions and recesses) that automatically align and secure the pipes to each other during assembly. The structure serves its own coupling function without requiring external coupling devices, achieving both ease of assembly and structural reliability.
2Ease of operation
If a band is used for coupling the upper pipe and the lower pipe, then the pipe can be assembled, but the band is inconvenient to carry and reduces installation efficiency
Solution Approach 1:
The coupling function is extracted from the assembly process and integrated directly into the pipe structure. The coupling protrusions and recesses are formed as integral parts of the upper and lower pipes during manufacturing, eliminating the need to carry and install separate bands, thereby improving installation efficiency and ease of operation.
Solution Approach 2:
The coupling features are prepared in advance during pipe manufacturing, with protrusions and recesses pre-formed on the pipe bodies. This preliminary action eliminates the need for separate coupling components during installation, streamlining the assembly process and improving installation efficiency.
3Ease of manufacture
If a band is used for coupling the upper pipe and the lower pipe, then the pipe can be assembled, but the band costs much and increases installation costs
Solution Approach 1:
The coupling function is merged into the pipe structure itself, eliminating the need for separate band components. This integration reduces material requirements and installation costs while maintaining assembly ease through the built-in coupling features.
Solution Approach 2:
The invention replaces expensive reusable bands with cost-effective integral coupling features formed directly on the pipes. The coupling protrusions and recesses are manufactured as part of the pipe structure, eliminating the need for additional coupling components and reducing overall installation costs.

AI summary
The present invention relates to a cable protection pipe which accommodates a cable to prevent the cable from being damaged by external force, is easily assembled and disassembled when the cable is accommodated therein, and reduces installation costs. To this end, the cable protection pipe includes a first body unit, and a second body unit facing and coupled to the first body unit. The first body unit and the second body unit are coupled in a form of a hollow pipe capable of accommodating a cable therein. In particular, a first body coupling projection and a first position determining protrusion protrude from a first lower coupling surface, and a first lower body coupling hole and a first lower position determining groove are formed on the second lower coupling surface. A first upper coupling surface includes a first upper body coupling hole to couple with the first body coupling projection, and a first upper position determining groove to couple with the first position determining protrusion. A second upper coupling surface includes a second body coupling projection to couple with a first lower body coupling hole, and a second position determining protrusion to couple with a first lower position determining groove.
