Bi-stable Hinge for Flexible Display Snap Closure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current information handling systems lack flexible and efficient display configurations that support multitasking and extended usage scenarios, particularly in transitioning between open, closed, and reader positions, with existing hinges failing to provide robust and versatile support for multiple display orientations.
Innovation Solution
The implementation of bi-stable hinges with a curved cross section and a bend zone, made from durable materials like silicon or spring steel, which allow the display platforms to snap into different positions while providing support to a flexible display screen, enabling multiple orientations and automatic transitions between open, closed, and reader positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional hinges are used to connect display platforms, then the structure is simple, but the hinge cannot provide robust support for multiple display orientations and automatic transitions
Solution Approach 1:
The hinge employs a bi-stable mechanism that automatically transitions between open and closed positions based on applied force, eliminating the need for manual locking or complex control systems. The hinge dynamically adapts to user input and maintains stable positions without continuous energy input.
Solution Approach 2:
The hinge utilizes material elasticity and geometric configuration to create two stable equilibrium states. By changing the physical parameters of the hinge structure (curved cross-section, bend zone location), it achieves bi-stability that enables multiple display orientations without additional actuators.
2Ease of operation
If a bi-stable hinge with curved cross section is used, then automatic transition between positions is enabled, but the hinge requires durable materials like silicon or spring steel
Solution Approach 1:
The hinge design optimizes the bend zone location and cross-sectional curvature to achieve bi-stability using conventional materials. By adjusting geometric parameters rather than relying on exotic materials, the design becomes more manufacturable while maintaining automatic transition functionality.
3Adaptability or versatility
If the hinge allows multiple display orientations, then usage versatility is improved, but the force required to maintain positions increases
Solution Approach 1:
The bi-stable hinge automatically maintains display positions without requiring continuous external force. The elastic deformation of the hinge itself provides the restoring force, eliminating the need for motors, springs, or actuators to maintain orientation.
Solution Approach 2:
The hinge uses its own elastic deformation to provide the force necessary to maintain display positions. The bi-stable structure inherently generates the restoring force through its material properties and geometric configuration, making the system self-sustaining without external power sources.

AI summary
An information handling system includes a flexible display screen, first and second display platforms, and a bi-stable hinge. The flexible display screen is movably mounted to the first and second display platforms. The bi-stable hinge is mounted to the first and second display platforms and couples the first display platform to the second display platform. The bi-stable hinge locks the first and second display platforms in an open position and snap closes the first and second display platforms from the open position to a closed position in response to the bi-stable hinge being stressed in a first direction.
