Dual Retractable Hinge for Large Tablet Cover Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sliding hinges with a single resilient positioning assembly are insufficient to maintain the base and cover positions of large-sized electronic devices, such as tablet computers, due to inadequate resilient force.
Innovation Solution
A sliding hinge design featuring two sliding assemblies, two pivoting assemblies, and two retractable connecting assemblies, where the retractable connecting assemblies provide sufficient resilient force to hold the cover in closed or open positions through a combination of springs and connectors, allowing for secure positioning of large-sized electronic devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a single resilient positioning assembly is used in a sliding hinge, then the device complexity is reduced and manufacturing is easier, but the resilient force is insufficient to hold the base and cover at specific positions in large-sized electronic devices
Solution Approach 1:
The single resilient positioning assembly is divided into multiple resilient positioning assemblies (first and second assemblies). Each assembly independently provides resilient force, and together they generate sufficient total force to hold the cover at specific positions in large-sized electronic devices, while maintaining manageable complexity through modular design
Solution Approach 2:
Multiple resilient positioning assemblies are combined to work together in unison. The first and second resilient positioning assemblies are positioned at different locations but cooperate to provide the necessary resilient force, effectively merging their individual force contributions to achieve the required holding capability
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The sliding hinge effectively maintains the cover of large-sized electronic devices in closed or open positions with sufficient resilient force, ensuring stability and secure engagement.
Implementation Method 1
a resilient positioning assembly connected to the base and the cover of the electronic device. When the cover slides relative to the base, resilient force of the resilient positioning assembly pushes the cover to stay at the open position or the closed position

AI summary
A sliding hinge has two sliding assemblies mounted on a cover of an electronic device, two pivoting assemblies mounted on a base of the electronic device and two retractable connecting assemblies. An end of one retractable connecting assembly is connected to the end of the other retractable connecting assembly. Another end of each retractable connecting assembly is pivotally connected to a corresponding sliding assembly and a corresponding pivoting assembly. The two retractable connecting assemblies of the sliding hinge provide sufficient resilient force to push and hold the cover of the electronic device, especially a large-sized electronic device, at the closed or open position.
