Hinge With Translatable Pivot Axis for Flexible Device Configurations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hinges in hybrid computers have a single pivot point, limiting the range of orientations and positions that the first and second bodies can assume, restricting user experience and device geometry.
Innovation Solution
A hinge system with a translatable pivot point mechanism that allows the pivot point to move vertically relative to the second body, enabling a wider range of orientations and positions through a translation mechanism connected to the first pivot point.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional hinge with a single pivot point is used, then the structure is simple and reliable, but the range of orientations and positions is limited
Solution Approach 1:
The hinge pivot point is made translatable along the hinge axis, transforming a static hinge structure into a dynamic one. The pivot point can move between a first position (providing greater opening angle) and a second position (providing different geometric configuration), allowing the hinge to adapt to multiple device orientations and positions while maintaining structural reliability
Solution Approach 2:
The hinge structure is segmented into movable and fixed components, with the pivot point able to transition between discrete positions. This segmentation allows the hinge to provide multiple functional states (different pivot positions) while maintaining a relatively simple overall structure, resolving the contradiction between versatility and complexity
2Length of moving object
If the pivot point is fixed, then the hinge structure is stable and simple, but the device height in closed state cannot be reduced
Solution Approach 1:
The pivot point transitions from a fixed position to a dynamic position that can move along the hinge axis. In the closed state, the pivot point moves to the second position which reduces the device height, while in the open state it moves to the first position providing greater opening angle. This dynamic positioning resolves the contradiction between reducing device dimensions and maintaining structural simplicity
3Adaptability or versatility
If a translatable pivot point is implemented, then the device configuration flexibility is enhanced, but the hinge mechanism becomes more complex
Solution Approach 1:
The translation mechanism is segmented into discrete positional states (first pivot position and second pivot position) rather than continuous movement. This segmentation provides configuration flexibility while limiting the complexity of the translation mechanism, as it only needs to support movement between specific positions rather than continuous adjustment
Solution Approach 2:
A translation mechanism acts as an intermediary between the hinge pivot and the device bodies, enabling pivot point movement without directly complicating the main hinge structure. This intermediary component provides the necessary flexibility while isolating the complexity to a specific subsystem

AI summary
A hinge system has a first body and a second body rotatably connected to one another around a first pivot point. The second body has a top surface and bottom surface positioned opposite one another in a vertical direction of the second body. A translation mechanism is connected to the second body and the first pivot point to displace the first pivot point in the vertical direction relative to the second body.
