Hinge Cable Routing Layout for PCB Space and Signal Quality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing cabling manner on circuit boards of electronic devices occupies layout area and affects signal quality due to interference and signal degradation.
Innovation Solution
The electronic device employs a rotating shaft with a bracket that guides the cable externally, allowing it to be cabled between the first body and the rotating shaft, using a cable slot parallel to the shaft to restrict the cabling route and minimize interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the cable is cabled on the circuit board, then the cabling is simple, but the layout area of the circuit board is occupied and signal quality is degraded
Solution Approach 1:
The cable is extracted from the circuit board and routed externally through a cable slot in the bracket. The bracket serves as an independent cabling structure, separating the cable routing function from the circuit board, thereby freeing up layout area on the circuit board while maintaining organized cable management.
2Ease of manufacture
If the cable is cabled on the circuit board, then the cabling is simple, but signal interference increases and signal quality deteriorates
Solution Approach 1:
The cable is extracted from the circuit board environment and routed through the bracket's cable slot, physically separating it from potential sources of electromagnetic interference on the circuit board. This reduces signal interference while maintaining simple cable routing through the bracket structure.
3Area of stationary object
If the cable is routed externally through the bracket, then the layout area of the circuit board is freed up, but the cabling structure becomes more complex
Solution Approach 1:
The bracket is designed to serve multiple functions: it provides structural support for the rotating shaft, guides the cable through its cable slot, and positions the cable relative to the circuit board. This multi-functionality reduces the need for separate dedicated cabling components, thereby limiting the increase in overall device complexity.
4Object-affected harmful factors
If the cable is routed externally through the bracket, then signal interference is reduced, but additional hardware components are required
Solution Approach 1:
The bracket is designed as a multi-functional component that simultaneously provides structural support and cable routing capabilities. By integrating the cable slot into the existing bracket structure, the patent avoids adding separate dedicated cable management components, thereby limiting the increase in hardware component quantity.

AI summary
This application discloses an electronic device, including a rotating shaft, and a first body and a second body that are respectively disposed on two sides of the rotating shaft. The first body includes a first circuit board. The first circuit board is spaced from the rotating shaft. A cable is disposed between the first circuit board and the rotating shaft, and at least partially extends in an axial direction of the rotating shaft. In this way, the cable may be cabled externally instead of being cabled on the first circuit board, to reduce occupation of a layout area on the first circuit board, so that the first circuit board has a larger layout area for arranging another functional component. In addition, the first circuit board can be further prevented from causing signal interference to the cable, thereby ensuring signal quality.
