Foldable Device Coaxial Cable Routing Through Hinge Recesses
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge of balancing display size and portability in electronic devices is exacerbated by the trade-off between battery capacity and device thickness, where increasing battery size to support long battery life leads to increased device thickness and reduced portability.
Innovation Solution
An arrangement structure for a coaxial cable within a foldable electronic device that includes a hinge structure connecting two housings, with a bracket having recesses for the coaxial cable to pass through, allowing for the coaxial cable to be securely positioned without increasing device thickness, thereby ensuring space for a battery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If the battery capacity is increased to support long battery life, then the operating duration is improved, but the device thickness increases and portability deteriorates
Solution Approach 1:
The patent routes the coaxial cable through the thickness dimension of the device by creating recesses in the bracket structure. This allows the cable to pass through the Z-axis (thickness direction) rather than occupying lateral space, enabling increased battery capacity without increasing device thickness.
Solution Approach 2:
The coaxial cable is nested within recesses formed in the bracket structure. The first recess in the first bracket and the second recess in the second bracket provide dedicated pathways that integrate the cable routing into the existing structural components, eliminating the need for additional space.
2Use of energy by moving object
If the battery size is increased to provide more power, then the energy capacity is improved, but the device volume increases and portability is reduced
Solution Approach 1:
The patent utilizes the thickness dimension (Z-axis) for cable routing by forming recesses through the bracket structure. This dimensional approach allows the coaxial cable to occupy space in the thickness direction rather than lateral dimensions, preserving overall device volume while accommodating larger battery capacity.
3Area of stationary object
If the display screen size is increased with minimal bezel, then the screen-to-body ratio is improved, but the available internal space for components is reduced
Solution Approach 1:
The patent routes the coaxial cable through the thickness dimension of the device structure by creating recesses in the brackets. This approach allows the cable to pass through the Z-axis without occupying lateral space that would be needed for display or battery components, enabling larger display areas while maintaining internal component space.
