Solution Overview

Problem

Conventional touch pads on electronic devices lack the flexibility to perform comprehensive operations like selecting, clicking, executing, and dragging, requiring physical keys for better functionality, limiting their ability to fully replace traditional mice.

Innovation Solution

A touch input method that detects a first and second input position on a touch module to form commands, allowing the pointer to execute specific functions based on the detected input signals, enabling more flexible and comprehensive operations without physical keys.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a touch pad is used to control the pointer on the display screen, then the device portability and integration are improved, but the operational flexibility and functionality are worsened

Engineering Contradiction:
Improvedevice integrationVSAvoidoperational flexibility
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent transitions from single-point touch detection to multi-point touch detection, adding spatial dimensionality to the input method. By detecting both first and second input positions simultaneously on the touch pad, the system creates a two-dimensional input space that enables complex commands (select, execute, drag) without physical keys, thus maintaining integration while improving operational flexibility

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The touch pad input area is segmented into multiple detectable positions (first input position and second input position). Each position can be independently detected and combined to form different commands. This segmentation allows the touch pad to simulate multiple button functions without physical keys, resolving the contradiction between integration and operational flexibility

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If physical keys are added to the touch pad to improve functionality, then the operational capability is improved, but the device complexity and design simplicity are worsened

Engineering Contradiction:
Improvefunctional capabilityVSAvoiddevice design
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The touch pad is designed to perform multiple functions (select, execute, drag operations) through software-based multi-point detection rather than adding physical keys. The same touch pad surface serves both as the display interface and as the input controller for all operations, eliminating the need for additional physical components while maintaining functional capability

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent replaces mechanical physical keys with electronic multi-point touch detection. Instead of using mechanical switches or buttons, the system uses capacitive or resistive touch sensing to detect multiple input positions simultaneously, forming commands through software processing. This substitution maintains functionality while simplifying the mechanical structure

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Adaptability or versatility

If multi-point touch detection is implemented, then the command formation capability is improved, but the detection complexity and processing requirements are worsened

Engineering Contradiction:
Improvecommand formation capabilityVSAvoiddetection complexity
Core Design Contradiction:
Adaptability or versatilityVSDifficulty of detecting and measuring

Solution Approach 1:

The system establishes a detecting period framework in advance, within which multiple input positions are detected and processed. By pre-defining the detection window and processing sequence, the system manages the complexity of multi-point detection through structured temporal organization, making the detection and command formation process more manageable

Inventive Principle:
Principle #10Preliminary action
