Cable Guide Channel and Wing for Notebook Hinge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in notebook personal computers is to manage cables effectively outside the hinge section without compromising assembly performance, as the increasing density of components within the housing limits space for cable routing and existing solutions do not address this issue.
Innovation Solution
The implementation of a guide channel with a vertically extending slit and a wing to secure cables outside the hinge section, ensuring they remain in a correct wiring route and prevent dislodgment, combined with a lid that covers the cable and connector openings for aesthetic and protective purposes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a wiring route running outside the hinge section is employed, then cable routing flexibility is improved, but assembly performance deteriorates due to difficulty in assembling the device including wiring
Solution Approach 1:
The guide channel is pre-formed in the housing with a specific structure including a wing and slit, which preliminarily positions and secures the cable before final assembly. This preliminary action ensures that the cable is automatically guided and fixed in the correct position during assembly, resolving the contradiction between external routing flexibility and assembly difficulty
Solution Approach 2:
The guide channel acts as an intermediary structure between the housing and the cable. It provides a dedicated pathway with a wing and slit that mediates the connection, making cable installation easier while maintaining external routing flexibility. The guide channel translates the rigid housing structure into a cable-friendly environment
2Volume of moving object
If multiple components are densely packed in the housing, then device size is reduced, but cable routing space becomes extremely limited
Solution Approach 1:
The guide channel utilizes the vertical dimension by extending downward from the outer surface of the housing. This dimensional approach allows cable routing in the thickness direction of the housing, effectively creating cable routing space without increasing the planar footprint, thus resolving the contradiction between compact device size and limited cable routing space
Solution Approach 2:
The guide channel structure, particularly the wing and slit configuration, creates a flexible routing path within the constrained housing volume. The channel accommodates cable movement while maintaining compact dimensions, effectively providing cable routing space within the limited volume through clever structural design

AI summary
An electronic apparatus has two housings. One of the housings serves as a first housing and has a guide channel that vertically guides a vertically extending cable. The first housing also has a wing that covers a side of the guide channel except a vertically extending slit.
