Linked Hinge Mechanism With Partial Passive Unit Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional notebook computer hinge mechanisms face challenges in designing a linked mechanism that accommodates the movement of additional components like decoration shields and supporting posts within the limited space, while allowing for desired rotational functionality.
Innovation Solution
A linked hinge mechanism comprising a first member, a second member, a hinge unit, and a passive unit, where the hinge unit connects the first and second members, allowing the first member to rotate relative to the second member, and the passive unit is moved by the hinge unit within a portion of its rotation range, providing intermittent rotation by disengaging when reaching a specific orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a linked mechanism is designed to move additional components (decoration shield, supporting posts) with the hinge mechanism, then the functionality and completeness of the notebook are improved, but the device complexity and space requirements increase
Solution Approach 1:
The rotation range of the hinge unit is divided into multiple ranges, with the passive unit engaged only in a first rotation range and disengaged in a second rotation range. This segmentation allows the linked mechanism to operate only when needed, reducing overall complexity while maintaining functionality.
Solution Approach 2:
The linkage between the hinge unit and passive unit is made dynamic through engagement and disengagement mechanisms. The passive unit can be selectively connected or disconnected from the hinge unit, allowing the system to adapt its complexity based on operational requirements.
2Ease of operation
If the passive unit is rotated by the hinge unit throughout the entire rotation range, then the intermittent rotation effect is achieved, but the space required for component movement increases
Solution Approach 1:
The rotation range is segmented into multiple ranges, with the passive unit rotating only in a portion of the total range. This reduces the volume required for component movement while maintaining the intermittent rotation effect needed for decorative purposes.
Solution Approach 2:
The passive unit performs its rotation function only partially, during specific portions of the hinge unit's rotation range, rather than throughout the entire range. This partial action achieves the desired intermittent effect while minimizing space requirements.
3Stability of the object's composition
If the passive unit is continuously engaged with the hinge unit, then the rotation is smooth and continuous, but the intermittent rotation effect required for aesthetic purposes is lost
Solution Approach 1:
The engagement state of the passive unit is made dynamic, allowing it to be connected during certain rotation ranges and disconnected during others. This dynamic adjustment enables the system to achieve both continuous rotation when needed and intermittent rotation for aesthetic purposes.
Solution Approach 2:
The passive unit engages and disengages periodically during the rotation cycle, creating the intermittent rotation effect. This periodic action allows the decoration shield to move smoothly during engagement while remaining stationary during disengagement, achieving the desired aesthetic effect.

AI summary
A linked hinge mechanism includes a first member, a second member, a hinge unit and a passive unit. The hinge unit is connected to the first member and the second member, wherein the first member is adapted to be rotated relative to the second member via the hinge unit. The passive unit is adapted to be moved by the movement of the hinge unit, wherein the passive unit is adapted to be rotated by the movement of the hinge unit in only a portion of the whole rotation range of the hinge unit.
