Multi-Stage Hinge Assembly Automatic Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional notebook computer locking assemblies require manual intervention and can be damaged by excessive force, leading to potential deformation or fracture of the hook structure, and do not automatically lock the display, compromising portability and aesthetics.
Innovation Solution
A multi-stage hinge assembly with a pivot and connecting portion featuring first and second trenches of different widths, allowing a protrusion to automatically lock the shell portions by sliding into the second trench during closure, eliminating the need for a hook and enhancing visual appeal through a hidden design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a conventional locking assembly with hook and slot is used, then the notebook computer can be locked, but the locking assembly cannot automatically lock during closing operation and requires manual intervention
Solution Approach 1:
The hinge assembly automatically locks itself during the closing operation without requiring manual intervention. The protrusion on the pivot automatically engages with the second connecting portion when the display is closed, achieving self-service locking functionality.
Solution Approach 2:
The locking action is prepared in advance through the mechanical design of the hinge assembly, where the protrusion and connecting portions are positioned to automatically engage when the closing motion occurs, eliminating the need for separate locking actions.
2Reliability
If the user applies too-large force during closing, then the locking may be achieved, but the hook tends to be damaged and thus influences the operation of the locking assembly
Solution Approach 1:
The hinge assembly incorporates a controlled closing mechanism through the multi-stage connection design, where the protrusion sequentially engages with the first and second connecting portions. This staged engagement cushions the closing force and prevents excessive force from damaging the locking components.
3Reliability
If the closing force is too large, then the locking may be achieved, but the side frame of the liquid crystal display may be damaged
Solution Approach 1:
The multi-stage hinge connection design cushions the closing force by distributing it through sequential engagement of the protrusion with the first and second connecting portions, preventing excessive force from damaging the display side frame.
4Reliability
If most of the locking assemblies are exposed from the liquid crystal display or host, then the locking function is achieved, but the glory is influenced and the locking assembly may deform or fracture
Solution Approach 1:
The hinge assembly merges the locking function with the hinge structure itself, integrating the locking components into the existing mechanical connection between the display and host. This eliminates the need for separate exposed locking assemblies, improving both aesthetics and structural integrity.
5Shape
If a hidden hinge design is used, then the aesthetics are improved, but the automatic locking mechanism becomes more complex
Solution Approach 1:
The hinge assembly performs multiple functions simultaneously: it provides the rotational connection between display and host, and it provides the automatic locking mechanism through the protrusion and connecting portions. This multi-functionality reduces the need for separate components, actually simplifying the overall structure while maintaining the hidden design.
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 multi-stage hinge assembly enables quick and automatic locking of the notebook computer's shell portions, preventing damage from excessive force and improving aesthetics by hiding the hinge mechanism, while reducing the force required for closure and preventing collisions during high-speed closing.
Implementation Method 1
A pivot extends from one side of the first component along a rotating axis... The connecting portion is disposed beside the second component and pivots on the pivot
Implementation Method 2
The first trench and the second trench are connected each other and respectively have different widths. The protrusion slides in the first trench or second trench

AI summary
A multi-stage hinge assembly connected between first and second shell portions includes a first component, a second component and a connecting portion. At least one part of the first component is fixed to the first shell portion. A pivot extends from one side of the first component along a rotating axis. A protrusion is disposed on the pivot. At least one part of the second component is fixed to the second shell portion. The connecting portion is disposed beside the second component and pivots on the pivot. When the first component rotates relative to the second component, the pivot or connecting portion rotates about the rotating axis. First and second trenches are disposed in the connecting portion and separate it into first and second connecting portions. The first and second trenches are connected together and have different widths. The protrusion slides in the first or second trench.
