Hinge Assembly Cable Insertion and Retention Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hinge assemblies for electronic devices face difficulties in cable installation, leading to potential entanglement and poor connections, as well as challenges in detecting cable defects during the installation process.
Innovation Solution
A hinge assembly design featuring a first and second coupling member with aligned holes and slots, along with a rotatable limit member, creates a compartment for cable insertion and retention, ensuring the cable is securely housed and preventing exit, with the limit member rotating to close the entrance and retain the cable.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the cable is inserted through the hinge assembly using conventional methods, then the cable installation process is simple, but the cable may become entangled and suffer poor connection with the electronic device
Solution Approach 1:
The hinge assembly is divided into multiple components: a first coupling member with a first hole and first slot, a second coupling member with a second hole and second slot, and a limit member with a third hole and third slot. These segmented components collectively form a controlled cable insertion path that prevents entanglement while maintaining ease of installation.
Solution Approach 2:
The limit member acts as an intermediary component that controls the cable insertion process. It includes a third hole and third slot that align with the first and second holes and slots to form a complete insertion path, and can rotate to close the entrance and retain the cable, ensuring proper connection without entanglement.
2Reliability
If the cable is concealed within the hinge assembly for protection and aesthetics, then the cable is protected from damage and improves appearance, but it becomes difficult to judge whether the cable has defects or was damaged during installation
Solution Approach 1:
The hinge assembly provides a controlled preliminary insertion path through aligned holes and slots before the cable is fully concealed. This allows visual inspection and detection of cable defects during the insertion process itself, before the cable is hidden within the assembly for protection and aesthetics.
3Ease of manufacture
If multiple factories handle the hinge assembly and cable separately, then each factory can specialize in their respective components, but it becomes difficult to judge whether the cable itself has defects or whether the cable is damaged during installation
Solution Approach 1:
The limit member with its controlled insertion path serves as an intermediary mechanism that can be integrated into the assembly process. It provides a standardized interface that allows factories to specialize in their respective components while maintaining the ability to detect cable defects at the point of insertion, regardless of which factory performs the assembly.

AI summary
A hinge assembly, which allows a cable to be disposed therein quickly, includes a first coupling member with a first hole and a first slot, a second coupling member with a second hole and a second slot, and a limit member with a third hole and a third slot. The first, second and third holes collectively define a compartment, with the first, second and third holes being aligned one another. The first, second and third slots collectively define an entrance, with the first, second and third slots being aligned one another. The entrance defines a space with a size greater than a cross-sectional size of the cable to allow insertion of the cable. The limit member is operably rotatable to a position that the cable is retained in the compartment and is prevented from exiting from the entrance.
