Hinge Assembly with Translation Mechanism for Display Stabilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices with touch screen interfaces face instability due to oscillation of the display caused by user input, which existing hinge assemblies fail to adequately address by allowing simultaneous rotation and translation of the display section relative to the base section.
Innovation Solution
A hinge assembly with a translation assembly that includes a drive gear, driven gear, and linkage system, allowing the second section of the chassis to translate along an axis as it rotates, enabling effective stabilization of the display during touch screen operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a hinge assembly allows rotation of the display section, then the device gains flexibility in display positioning, but the display becomes unstable and oscillates during touch screen operation
Solution Approach 1:
The hinge assembly incorporates a translation assembly with drive and driven gears that dynamically adjust the display section's position. As the display rotates, the translation assembly automatically translates the display along an axis perpendicular to the rotation axis, providing continuous stabilization without requiring manual intervention or complex control systems.
Solution Approach 2:
The translation assembly acts as an intermediary mechanism between the rotation hinge and the display section. It mediates the relationship between rotational movement and display stability by converting part of the rotation into perpendicular translation, thereby reducing oscillation and stabilizing the display during touch operations.
2Stability of the object's composition
If a hinge assembly allows simultaneous rotation and translation of the display section, then display stability improves, but the device complexity increases
Solution Approach 1:
The translation assembly is integrated directly into the hinge assembly structure, merging the rotation and translation functions into a single unified mechanism. The drive gear is coupled to the rotation hinge, and the driven gear is coupled to the translation assembly, allowing both functions to operate simultaneously through a compact, interconnected design rather than separate systems.
Solution Approach 2:
The hinge assembly serves multiple functions: it provides the primary rotation capability for display positioning, simultaneously activates the translation assembly to stabilize the display during rotation, and integrates both functions through a shared gear mechanism. This multi-functionality reduces the need for additional separate stabilization mechanisms.
