Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing touch screen technologies are limited in their ability to perform complex operations due to reliance on touch position, pattern, and time, which restricts controllable interactions as devices integrate multiple functions and diversify.
Innovation Solution
A method for selecting screens on a touch screen using pressure touches, involving first and second pressure touches to define a selection area, allowing for scroll or drag operations, image capture, deletion, or transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing touch control types (based on touch position, pattern, or time) are used, then the device can perform basic operations, but the controllable operations are limited when functions are integrated and diversified
Solution Approach 1:
The patent introduces pressure as a new parameter for touch control, transforming the traditional 2D touch interface into a 3D interface by adding the pressure dimension. This allows the system to distinguish between different touch intensities and perform diverse operations based on pressure levels, thereby increasing adaptability without requiring fundamentally new control mechanisms
Solution Approach 2:
The pressure-based touch control system serves multiple functions: it can perform basic selection operations, enable scroll operations through sustained pressure, trigger capture operations, and differentiate between various interaction types all within a single unified control mechanism, replacing the need for multiple separate control types
2Adaptability or versatility
If a new touch type based on pressure is implemented, then various applications can be executed with enhanced functionality, but it becomes difficult to detect both existing touch types and the new pressure touch type simultaneously
Solution Approach 1:
The patent segments touch detection into distinct pressure-based categories by establishing pressure threshold levels. Light touches below the threshold are detected as conventional taps, while touches exceeding the threshold are recognized as pressure-based operations. This segmentation allows the system to process different touch types through dedicated detection pathways, eliminating interference between traditional and pressure-based touch recognition
3Ease of operation
If pressure-based touch control is used, then screen selection and manipulation become easier with enhanced operational flexibility, but the system must process additional pressure parameter data
Solution Approach 1:
The system performs preliminary classification of touches by comparing pressure values against predetermined thresholds before initiating specific operations. This preliminary action filters and categorizes pressure data in advance, allowing the system to route different touch types to appropriate handling routines without requiring complex real-time analysis, thereby simplifying the processing workload
