Rotating Shaft Cable Organizer Locking Structure Against Pull-Off
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable organizers for rotating shafts are prone to disengagement over time due to being easily pulled off, necessitating additional fixing methods like glue or screws, which complicate the assembly process and affect the appearance.
Innovation Solution
A connecting structure that includes a case with a hollow shell and an assembly plate, where two through holes are formed between the assembly plate and the hollow shell, allowing inserts of the cable organizer to penetrate and engage with the hollow shell, preventing disengagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the cable organizer is fixed using glue, then the engagement between the cable organizer and case is improved, but the assembly process complexity increases and appearance is affected due to glue overflow
Solution Approach 1:
The patent replaces the chemical bonding method (glue) with a mechanical interlocking system consisting of inserts with locking structures that engage with corresponding features on the cable organizer. This mechanical substitution eliminates the need for glue application procedures, prevents appearance defects from glue overflow, and maintains reliable engagement through the locking mechanism.
Solution Approach 2:
The patent introduces inserts as intermediary components that mediate the connection between the case and the cable organizer. These inserts contain locking structures that mechanically interlock with the cable organizer, providing a reliable connection without requiring direct gluing between the case and cable organizer, thus simplifying the assembly process while maintaining engagement reliability.
2Reliability
If the cable organizer is fixed using screws, then the engagement between the cable organizer and case is improved, but the assembly process complexity increases and additional parts are required
Solution Approach 1:
The patent merges the functions of the inserts and the cable organizer into an integrated assembly where the locking structures are built into the insert design itself. This integration eliminates the need for separate screw components and assembly steps, reducing part count and simplifying the assembly process while maintaining reliable mechanical engagement through the integrated locking mechanism.
3Device complexity
If the cable organizer is assembled without additional fixing structures, then the assembly process is simplified, but the cable organizer easily disengages after prolonged use
Solution Approach 1:
The patent incorporates elastic elements within the inserts that provide dynamic locking action. The elastic structures deform during assembly to allow insertion, then recover to maintain continuous locking pressure on the cable organizer, ensuring reliable engagement that resists disengagement over time while maintaining a simple single-step assembly process.
Solution Approach 2:
The patent designs the locking structures with preliminary anti-action features that prevent disengagement before it can occur. The locking protrusions and recesses are configured to automatically engage and lock the cable organizer in place during the insertion process, creating a mechanical barrier that prevents backward movement or disengagement without requiring additional fixing operations.

AI summary
A connecting structure includes a case, a rotating shaft, and a cable organizer. The case includes a hollow shell and an assembly plate. The assembly plate is accommodated in the hollow shell, and two through holes are formed between two opposite side edges of the assembly plate and an inner wall of the hollow shell. The rotating shaft is assembled to one side of the assembly plate. The cable organizer includes a tubular body, a spacer, and two inserts. The spacer is located at one end of the tubular body, and the two inserts are located at two opposite sides of another end of the tubular body. When the cable organizer is assembled to the case from the other side of the assembly plate, the two inserts respectively penetrate through the two through holes and are engaged with and fixed to the inner wall of the hollow shell.
