Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current touch screens, especially large-sized ones, require users to move the touching object back and forth across the screen for operations, leading to inefficiency, inconvenience, and potential for incorrect selections due to small menu interfaces.
Innovation Solution
An optical touching assembly with a touching object featuring optical controlling elements that generate varying light characteristics as it moves, allowing the sensing device to detect motion and trigger display functions without the need for direct user interaction with menu items, thereby improving efficiency and accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If users operate large touch screens by moving the touching object to menu positions, then the touching function can be realized, but the operation efficiency decreases and user convenience deteriorates due to repeated back-and-forth movements
Solution Approach 1:
The patent replaces the mechanical movement of the touching object across the screen with an optical sensing system. The sensing device detects the position and motion of the touching object through optical signals (light blocking, reflection, or emission), converting physical movement into electronic signals for direct menu selection. This substitution eliminates the need for users to physically move the touching object to menu positions, thereby improving operation efficiency and user convenience.
2Area of stationary object
If the touch screen size increases, then the display area increases, but the menu interface size becomes smaller making selection accuracy decrease
Solution Approach 1:
The patent introduces an optical sensing device as an intermediary between the touching object and the menu interface. This sensing device accurately detects the position and motion of the touching object through optical signals, enabling precise menu selection even when the menu interface is small. The intermediary sensing mechanism decouples the relationship between screen size and menu size, allowing large display areas to maintain small, precise menu interfaces without sacrificing selection accuracy.
3Adaptability or versatility
If users need to access menu items located far from the current touching object position, then the menu can be accessed, but the operation time increases due to repeated movements
Solution Approach 1:
The patent replaces the mechanical process of moving the touching object across the screen with an optical detection system. The sensing device detects the touching object's position and motion state through optical signals, enabling direct menu selection without physical movement. This substitution eliminates the time-consuming back-and-forth movements while maintaining full menu accessibility, thereby reducing operation time significantly.
4Ease of operation
If the touching object remains stationary while accessing distant menu items, then movement is reduced, but the ability to perform touching operations is limited
Solution Approach 1:
The patent introduces an optical sensing device as an intermediary that detects the touching object's position and motion state. This sensing mechanism enables the system to understand user intent and perform appropriate operations without requiring the touching object to be physically moved to menu positions. The intermediary sensing system maintains full touching operation capability while allowing the touching object to remain stationary, thereby improving operation convenience.
