Shared Electromagnetic Digitizer for Closed-Device Input
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Computing devices with electromagnetic digitizers face delays in waking up from low power states, requiring users to wait before recording notes or drawings, especially when in closed orientations, as existing technologies do not efficiently enable input signal detection and processing without opening the device.
Innovation Solution
Incorporating an electromagnetic digitizer panel between the flat panel and the flat panel display, with circuitry to digitize input signals from both sides, allowing users to input signals using a stylus even when the device is closed, and utilizing a cholesteric liquid crystal display that can receive input and retain it without power, enabling immediate recording.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the device is in a closed orientation with existing technology, then power consumption is reduced, but input signal detection and processing are delayed
Solution Approach 1:
The digitizer is divided into two independent sides: a first side for receiving input signals when the device is open, and a second side for receiving input signals when the device is closed. This segmentation allows each side to be optimized for its specific use case, enabling immediate note-taking in closed orientation without affecting the overall system power management
Solution Approach 2:
The electromagnetic digitizer panel serves multiple functions: it can detect stylus input from both the first side (when device is open) and the second side (when device is closed), making it a universal input interface that adapts to different device orientations and usage scenarios
2Adaptability or versatility
If the device allows input from both sides, then versatility is improved, but device complexity increases
Solution Approach 1:
Both the first side and second side input capabilities are merged into a single electromagnetic digitizer panel, eliminating the need for separate digitizer components for each side. This integration achieves versatility while minimizing the increase in device complexity
