Switch Mechanism for Portable Device Display Pivoting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional notebook designs face challenges in mechanical design due to shrinking space for Hall effect switches and accuracy issues when the notebook casing is made of non-plastic materials like metal, affecting the magnetic field intensity and angle detection for switching between states.
Innovation Solution
A switch mechanism with a sliding track and component inside the host module, where the sliding component activates switches within the host module as the display module pivots, allowing for precise state switching without relying on magnetic fields, thus saving space and improving accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If Hall effect switches are disposed on lateral sides of the display module, then the operation system can switch to suspend state or power-off state, but the space for accommodating the Hall Effect switches inside the display module becomes smaller as the notebook becomes smaller and slimmer
Solution Approach 1:
The patent extracts the switch mechanism from the display module and relocates it to the host module. The sliding component is disposed on the host module and slides relative to the display module to activate switches, thereby removing the space constraint from the display module while maintaining the state switching function.
Solution Approach 2:
The patent changes the spatial arrangement by moving the switching mechanism from a lateral side disposition on the display module to a sliding disposition where the sliding component moves along a track on the host module. This dimensional reconfiguration allows the switches to be activated without occupying space within the display module.
2Shape
If the notebook appearance component is made of non-plastic material such as metal material, then the appearance quality is improved, but the magnetic field intensity of the Hall effect switch is affected, reducing the accuracy of angle detection
Solution Approach 1:
The patent replaces the magnetic field-based Hall effect switch with a mechanical switch mechanism. The sliding component physically contacts and activates switch components through mechanical movement, eliminating dependence on magnetic fields and thus removing the interference caused by metal appearance materials.
Solution Approach 2:
The patent introduces a sliding component as an intermediary mechanical element between the display module and the switch components. This mechanical intermediary transmits the pivoting motion to activate the switches without relying on magnetic field penetration, thereby overcoming the shielding effect of metal materials.
3Ease of operation
If the Hall effect switches are used for detecting the angle between display module and host module, then the state switching function is achieved, but the accuracy is affected by magnetic field interference from metal materials
Solution Approach 1:
The patent replaces the magnetic field-based detection system with a direct mechanical detection system. The sliding component's physical position and contact with switch components directly indicate the angle state, providing accurate detection without magnetic field interference from metal materials.

AI summary
A switch mechanism includes a sliding track disposed inside a host module, and a sliding component. An end of the sliding component is pivotally connected to a display module and the other end of the sliding component is slidably installed inside the sliding track. The sliding component slides in a first direction relative to the sliding track while the display module pivots in a first rotary direction relative to the host module. The switch mechanism further includes an activation component for moving to a first position corresponding to a first switch component to activate a first switch component while the sliding component slides in the first direction.
