Hinge Mechanism for Automatic Stand Retraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tablet computer stands require manual retraction to the casing for storage, which is inconvenient for users.
Innovation Solution
A hinge mechanism incorporating a base, resilient mechanism, rotating shaft, first cam member, and second cam member, where the first cam member cooperates with the second cam member to generate a resiliently recovery force, automatically retracting the stand into the casing when the device is closed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the stand is designed to expand with respect to the casing for adjustable positioning, then the usability and viewing comfort are improved, but the operation complexity increases because manual retraction is required
Solution Approach 1:
The hinge mechanism enables the stand to automatically retract into the casing without user intervention. The resilient mechanism stores energy during stand expansion and automatically releases it to drive retraction, making the system self-serving and eliminating the need for manual operation.
Solution Approach 2:
The hinge mechanism incorporates dynamic elements including a resilient mechanism that can expand and contract, and cam members that convert rotational motion into linear retraction motion. This dynamic design allows the stand to automatically adjust its position and retract without manual intervention.
2Ease of manufacture
If the stand structure is simplified for easy manufacturing, then the production cost is reduced, but the automatic retraction function cannot be achieved
Solution Approach 1:
The hinge mechanism is divided into distinct functional modules: a base, a resilient mechanism with fixing members and resilient members, a rotating shaft with cam members, and a moving frame. This segmentation allows each component to be manufactured separately using standard processes and then assembled, maintaining ease of manufacture while achieving automatic retraction functionality.
3Ease of operation
If the resilient mechanism is added to enable automatic retraction, then the operation convenience is improved, but the device complexity and component count increase
Solution Approach 1:
The hinge mechanism merges multiple functions into a single integrated assembly. The resilient mechanism, cam members, and rotating shaft work together as a unified system to provide both the expansion and automatic retraction functions, reducing the need for separate actuators or complex control systems.

Function Achieved in This Case
Enhances convenience by allowing the stand to be automatically retracted into the casing without user intervention, simplifying the storage process of electronic devices like tablet computers.
Implementation Method 1
the first cam member displaces along the longitudinal axis relative to the second cam member for deforming the resilient mechanism... the resilient mechanism is a resilient frame... the spring arm portion extends from the flexibly abutting portion and is connected to the base

AI summary
A hinge mechanism includes a base, a resilient mechanism, a rotating shaft, a first cam member and a second cam member. The resilient mechanism is movably disposed on the base. The rotating shaft is rotably disposed through the base. The first cam member abuts against the resilient mechanism and is able to slide along the rotating shaft. The first cam member is able to move with the rotating shaft. The second cam member is mounted on the base and engages with the first cam member. The first cam cooperates with the second cam member during rotation with the rotating shaft, resulting in displacement between the first cam member and the second cam member for forcing the resilient mechanism to deform and generates a resilient recovery force. The resilient recovery force recovers the first cam member and the second cam member.
