Opposing Hook Socket Mechanism for Stable Laptop Screen Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current socket structures for detachable screens in laptops, which use hooks that move in the same direction, fail to provide stable fixation, leading to shakiness and instability.
Innovation Solution
A socket structure with two hooks that move in opposite directions, controlled by a single switch, utilizing a linkage, gear, and rotating arm mechanism, along with pogo pins and elastic members for secure engagement and easy operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If one hook or two hooks that move in the same direction are used to fix the screen, then the structure is simple, but the fixation is unstable and shaky
Solution Approach 1:
The fixing mechanism is divided into two independent hooks that can move in opposite directions. The first hook moves in a first direction while the second hook moves in a second direction (opposite to the first direction). This segmentation allows each hook to independently engage with corresponding features on the screen, providing stable fixation from multiple directions simultaneously.
Solution Approach 2:
Instead of having both hooks move in the same direction, the invention makes the hooks move in opposite directions. When the switch moves in the first direction, the first hook moves in the first direction while the second hook moves in the second direction (opposite direction). This inverted movement pattern creates opposing forces that stabilize the screen attachment.
2Stability of the object's composition
If two hooks moving in opposite directions are used, then fixation stability is improved, but the control mechanism becomes more complex
Solution Approach 1:
The control mechanisms for the two hooks are merged into a single switch. The switch is linked to both the first hook and the second hook through a linkage mechanism. When the switch moves, it simultaneously controls both hooks through the linkage, reducing the number of control elements from two separate switches to one unified control element.
Solution Approach 2:
A linkage mechanism acts as an intermediary between the single switch and the two hooks. The linkage translates the single switch's movement into coordinated movements of both hooks in opposite directions. This intermediary component simplifies the control architecture by providing a mechanical means to distribute a single control input to multiple actuators.
3Ease of operation
If a single switch controls both hooks, then ease of operation is improved, but the linkage mechanism complexity increases
Solution Approach 1:
The single switch performs multiple functions by controlling both the first hook and the second hook simultaneously. The switch is designed to move in the first direction to trigger both hooks, and can also move in a second direction to release both hooks. This multi-functionality consolidates what would otherwise require two separate control elements into one universal control device.
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 socket structure provides improved two-way fixation and ease of use by allowing the hooks to move in opposite directions with a single switch, ensuring stable attachment and automatic return to fixed positions, facilitating one-handed assembly and disassembly without continuous pressure.
Implementation Method 1
the elastic member is connected between the casing and the first hook to provide an elastic force along the second direction, and the other elastic member is connected between the casing and the second hook to provide an elastic force along the first direction

AI summary
A socket structure includes a casing, a switch, a linkage, a first hook, a gear, a rotating arm, and a second hook. The switch is exposed from the casing and disposed movably to the casing along a first direction or a second direction. The linkage is located in the casing and linked to the switch, and has a rack. The first hook is exposed from the casing and linked to the linkage. The gear is located in the casing and engages with the rack. The rotating arm having one end pivotally connected to the gear is located in the casing. The second hook is exposed from the casing and linked to the other end of the rotating arm. When the switch moves along the first direction, the linkage drives the first hook to move, the gear drives the rotating arm, and the second hook moves to an unlocked position.
