Rotatable Notebook Display Cable Routing via Planar Constraint
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Notebook computers with wide screens are limited in functionality as they are primarily designed for landscape mode, which is not ideal for tasks like browsing web pages or editing programs, and existing designs do not efficiently manage signal cables during mode changes.
Innovation Solution
A notebook computer design featuring a rotatable display portion with a supporting frame and sliding slot system, where signal cables are routed through a bendable section to prevent tangling and allow seamless mode switching between landscape and portrait orientations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display portion is made rotatable to enable switching between landscape and portrait modes, then the adaptability and functionality of the notebook computer is improved, but the signal cables may become intertwined or rubbed against each other during rotation
Solution Approach 1:
The patent guides the signal cables to move substantially along a plane during rotation by adjusting the bent angle of the bendable section. This planar movement constraint prevents the cables from intertwining or rubbing against each other in three-dimensional space, resolving the contradiction between rotatable display adaptability and cable entanglement issues
Solution Approach 2:
The patent employs a bendable section with adjustable bent angle in the signal cables. By changing the bent angle parameter during rotation, the cables can accommodate the rotational movement while maintaining planar alignment and preventing entanglement, thus enabling both rotatable display functionality and cable protection
2Reliability
If the signal cable is made rigid to maintain stable electrical connection, then the reliability of electrical coupling is improved, but the cable cannot accommodate the movement and rotation of the display portion
Solution Approach 1:
The patent incorporates a bendable section in the signal cable that can dynamically adjust its bent angle during display portion rotation. This dynamic flexibility allows the cable to accommodate movement while the sliding member constrains the movement to a plane, maintaining both electrical connection reliability and display mobility
3Adaptability or versatility
If the signal cable is made flexible to accommodate display rotation, then the adaptability during mode switching is improved, but the cable may become intertwined or damaged during movement
Solution Approach 1:
The sliding member with through hole guides the flexible signal cable to move substantially along a plane during rotation. This planar constraint prevents the cable from intertwining or rubbing against itself in three-dimensional space, allowing flexibility for rotation while preventing entanglement damage

AI summary
A notebook computer includes a host, a supporting frame and a display portion. The supporting frame is pivotally connected with the host and comprising a sliding slot. The display portion has a sliding member, which is pivotally connected with the supporting frame and slidably connected with the sliding slot, wherein the sliding member comprises a through hole. The signal cable is led through the through hole and extended within the supporting frame to electrically couple the display portion and the host. The signal cable comprises a bendable section. The signal cable is moved substantially along a plane by adjusting a bent angle of the bendable section when the display portion is slid along the sliding slot.
