Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If touch panel terminals use only touch position coordinates for identification, then the operation is simple, but the authentication security is insufficient

Engineering Contradiction:
Improveauthentication securityVSAvoididentification system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent segments the touch identification process into multiple independent parameters: touch position coordinates, touch pressure values, and touch duration. Each parameter is collected and processed separately, then combined to form a comprehensive user identification. This segmentation allows the system to enhance security without requiring a complete redesign of the identification system.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent transitions from two-dimensional touch position identification (x, y coordinates) to three-dimensional identification by adding the touch pressure dimension (force value). This dimensional expansion enables more accurate user identification while maintaining the simplicity of the touch interface, effectively resolving the contradiction between security and complexity.

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

2Measurement precision

If the system collects multiple touch parameters (position, pressure, duration), then the user identification accuracy improves, but the data processing complexity increases

Engineering Contradiction:
Improveuser identification accuracyVSAvoiddata processing complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent implements preliminary action by pre-defining the set of touch parameters to be collected (position, pressure, duration) and establishing the identification algorithm in advance. The system prepares the data collection framework beforehand, so that during actual operation, it only needs to gather and compare data against pre-established user profiles, reducing real-time processing complexity.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent uses copying by creating digital replicas of user touch patterns during the registration phase. These copied touch profiles (including position, pressure, and duration characteristics) are stored for comparison during authentication. This approach simplifies the authentication process by replacing complex real-time analysis with efficient pattern matching against stored copies.

Inventive Principle:
Principle #26Copying

3Reliability

If the touch panel uses pressure-sensitive detection for finger identification, then the authentication reliability improves, but the manufacturing cost increases

Engineering Contradiction:
Improveauthentication reliabilityVSAvoidmanufacturing cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent applies universality by designing a touch panel that serves multiple functions: basic touch input detection and biometric authentication. The same pressure-sensitive touch panel hardware is used for both general user interaction and secure identification, eliminating the need for separate authentication hardware and reducing overall manufacturing costs while maintaining high reliability.

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

AI summary

Provided are a system, method, and program for realizing an intuitive and efficient user interface based on the identification of each finger of a user. Actions are shown using instantly recognizable icons, labels, or both, and the user can recognize the function to be performed by displaying instantly recognizable icons, labels, or both on the fingertips of virtual hands representing fingers identified by a camera or other means. It allows many types of direct actions on an object of an action, with the number of types being more than the number of fingers by mode switching.
