Dual-Side Touch Control for Mobile Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile terminals face challenges in providing users with an intuitive and convenient method to select and execute functions without complex menu navigation, especially with the advent of bendable or curvable display units, and the need for innovative user input methods.
Innovation Solution
A mobile terminal design incorporating a display unit with first and second touch sensors on the front and rear surfaces, respectively, and a controller that outputs screen information and executes functions based on preset touches applied simultaneously to these regions, allowing for intuitive function selection and execution without extensive menu navigation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional menu navigation is used for function selection, then all functions can be accessed systematically, but the operation process becomes complicated and time-consuming
Solution Approach 1:
The patent pre-arranges specific touch patterns (simultaneous touches at predetermined positions) that directly map to functions or applications. This preliminary configuration allows users to execute functions immediately through intuitive gestures without navigating through menu structures, thereby resolving the contradiction between systematic access and operational simplicity.
Solution Approach 2:
The patent introduces a touch pattern recognition system as an intermediary between user input and function execution. Instead of direct menu navigation, the system interprets specific touch patterns (such as simultaneous touches at corners or edges) as commands, providing a more direct and convenient path to function execution while maintaining systematic control.
2Adaptability or versatility
If multiple touch sensors are added to enable new input methods, then user input capability is enhanced, but device complexity increases
Solution Approach 1:
The patent makes the existing touch sensors multi-functional by programming them to recognize various touch patterns (single touch, simultaneous touches, sequential touches) and map them to different functions. This approach enhances input versatility without adding new sensor hardware, thereby avoiding increased device complexity while achieving adaptability improvements.
Solution Approach 2:
The patent combines the functionality of multiple touch sensors into a unified control system that processes touch patterns collectively. By merging the input capabilities and processing logic, the system achieves enhanced versatility through coordinated operation of existing components rather than through additive complexity of separate systems.
