Electronic Paper Touch Panel Dynamic Area Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic paper touch panels in laptop computers have a fixed position and size, leading to accidental contacts and limited usability, as users cannot adjust the touch panel to suit their preferences, affecting user experience and input efficiency.
Innovation Solution
A control method and system that allows users to customize the position and size of the touch sensitive area on an electronic paper touch panel by detecting events via multiple touch electrodes and reporting only those within the designated area, using a touch sensitive processing apparatus and electronic paper controller connected to a host, which includes a driving circuit, sensing circuit, and interface module.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the touch panel has a fixed position and size, then the device structure is simple, but the user cannot adjust the touch panel to suit their preferences, affecting user experience and input efficiency
Solution Approach 1:
The patent implements dynamic adjustability of the touch-sensitive area by allowing users to define custom rectangular regions on the touch panel. The system dynamically adapts the active touch area based on user preferences, enabling the same hardware to serve multiple usage scenarios (e.g., different keyboard layouts, note-taking modes) without physical reconfiguration.
Solution Approach 2:
The patent changes the operational parameters of the touch panel by allowing dynamic modification of the touch-sensitive area's position and size. Users can adjust the rectangular region coordinates and dimensions to optimize the layout for different tasks, transforming a static parameter system into a flexible, user-configurable one.
2Area of moving object
If the touch panel area is small, then the device is compact, but the user may feel that area of the touch panel is too small to use
Solution Approach 1:
The system dynamically adjusts the effective touch area by allowing users to expand or contract the sensitive rectangular region. This enables the touch panel to adapt its operational area to match user needs - expanding when more space is required for comfort, and contracting when a smaller footprint is sufficient, thereby optimizing usability without changing the physical device size.
Solution Approach 2:
The patent modifies the operational parameters of the touch panel by enabling users to change the size parameters (width and height) of the touch-sensitive area. This parameter adjustment allows the same physical panel to provide different effective areas, resolving the contradiction between compactness and usability.
3Object-affected harmful factors
If the touch panel is positioned at the center, then the layout is symmetrical and simple, but the user cannot avoid accidental contacts with the touch panel while typing
Solution Approach 1:
The patent applies local quality by allowing users to define a specific rectangular region on the touch panel that differs from the default center position. This enables the touch-sensitive area to be relocated to optimal positions that avoid accidental contacts during typing, while non-sensitive areas remain inactive. Each user can customize the local characteristics of different regions on the panel.
Solution Approach 2:
The system dynamically repositions the touch-sensitive area based on user preferences and usage patterns. Instead of maintaining a fixed center position, the sensitive region can be moved to locations that minimize accidental contacts while typing, adapting to different hand positions and typing styles.
