Rotating Hinge Electrical Connection Elements for Cable Durability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing hinge structures in electronic devices, such as notebook computers, often cause damage or cracking to cables due to bending, pulling, or twisting during rotation, making assembly difficult and reducing durability.
Innovation Solution
A hinge structure with a first and second hinge, each having an accommodating space, and electrical connection elements that rotate together along an axis, allowing cables to connect through these elements to prevent damage during rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the cable is fixed and bent several times in the vicinity of the hinge, then the cable can be connected between the host and display, but the cable is easily damaged or cracked due to being pulled, twisted or rubbed against other components during rotation
Solution Approach 1:
The patent applies the dynamics principle by making the electrical connection element rotatable along with the hinge mechanism. The second electrical connection element is rotatably connected to the first electrical connection element along the rotation axis, allowing the cable connection point to dynamically follow the hinge rotation. This eliminates cable damage caused by fixed positioning during rotation, resolving the contradiction between ease of assembly and cable durability.
2Ease of manufacture
If the cable is bent several times to be fixed near the hinge, then connection is achieved, but the assembly and disassembly process becomes difficult
Solution Approach 1:
The patent extracts the cable routing complexity from the hinge assembly process by providing a dedicated accommodating space within the hinge structure for the electrical connection elements. The cable connects to the first electrical connection element which is positioned in this accommodating space, eliminating the need for complex bending and fixing operations near the hinge. This reduces assembly complexity while maintaining reliable cable connection.
3Adaptability or versatility
If a large angle of relative rotation between host and display is achieved, then versatility is improved, but the cable may easily be cracked due to the rotation
Solution Approach 1:
The patent introduces the rotatable electrical connection element as an intermediary between the cable and the rotating hinge mechanism. This intermediary component rotates along with the hinge, serving as a mediator that transfers rotational motion without transmitting damaging forces to the cable. This allows large rotation angles for versatility while protecting cable integrity through the intermediary's rotational capability.
