Foldable Hinge Structure With Wire Interlock for Larger Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a trade-off between the size of the display in electronic devices and their miniaturization, making it challenging to increase display size while maintaining portability.
Innovation Solution
The electronic device features a hinge structure with a rotation structure and an interlocking structure, including pulley shafts and a wire, that allows the device's housings to rotate relative to each other, enabling a larger display area without increasing the device's size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the display size is increased to support multimedia services, then the entertainment function is improved, but the device size increases and portability deteriorates
Solution Approach 1:
The device is divided into two separate housings (first housing and second housing) that can rotate relative to each other via the hinge structure. This segmentation allows the display to span across both housings, effectively doubling the display area while keeping each individual housing compact and portable.
Solution Approach 2:
The hinge structure enables the display to extend in a new spatial dimension by allowing the second housing to rotate relative to the first housing. This creates a multi-dimensional display configuration that increases the effective display area without proportionally increasing the footprint of each housing unit.
2Ease of operation
If a hinge structure with pulley shafts and wire is used to connect housings, then the rotation interlocking is improved, but the device complexity increases
Solution Approach 1:
The wire acts as an intermediary element that transfers rotational force between the two pulley shafts. This simple wire mechanism provides reliable rotation interlocking between the first and second housings without requiring complex mechanical linkages, gears, or electronic sensors.
Solution Approach 2:
The patent replaces complex mechanical interlocking systems (such as gears, cam mechanisms, or electronic motors) with a simple wire-and-pulley system. This mechanical substitution achieves the desired rotation interlocking function with fewer moving parts, reduced complexity, and improved reliability.

Function Achieved in This Case
This solution allows for a larger display area while maintaining the device's compactness, enhancing user experience by supporting multimedia services without compromising portability.
Implementation Method 1
a wire connected to the first pulley shaft and the second pulley shaft. The wire may be configured to rotate the second pulley shaft based on rotation of the first pulley shaft
