Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If touch operations are achieved by determining finger touch positions, then control commands can be inputted, but the touch operation steps become complicated and user experience is reduced

Engineering Contradiction:
Improvetouch operation stepsVSAvoidtouch operation process
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The system performs preliminary actions by pre-registering fingerprint templates and associating them with control commands before actual use. When a user touches the screen, the system compares the captured fingerprint against pre-stored templates and automatically executes the corresponding command, eliminating the need for multiple sequential touch operations.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system creates fingerprint template copies that represent unique user identifiers. These templates are stored in the system and used for rapid comparison during authentication. The fingerprint feature information (ridges, valleys, minutiae points) is copied and stored as reusable data structures that enable quick command execution without requiring repeated complex touch sequences.

Inventive Principle:
Principle #26Copying

2Adaptability or versatility

If multiple touch operations are required to input control commands, then various functions can be controlled, but the service life of the touch panel is reduced

Engineering Contradiction:
Improvecontrol functionsVSAvoidservice life of touch panel
Core Design Contradiction:
Adaptability or versatilityVSDuration of action of stationary object

Solution Approach 1:

The system enables self-service operation where the fingerprint authentication automatically triggers the appropriate control function without requiring the user to perform multiple touch operations. The fingerprint template matching system self-executes the command association, reducing mechanical stress on the touch panel from repeated finger interactions.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

Control commands are pre-associated with specific fingerprint templates during the registration phase. This preliminary configuration allows the system to directly execute functions based on fingerprint recognition, eliminating the need for subsequent multiple touch operations that would otherwise be required to navigate through menus and select functions.

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If fingerprint recognition is implemented to simplify operations, then user experience is improved, but the system must verify and match fingerprint features

Engineering Contradiction:
Improveoperation simplificationVSAvoidfingerprint feature matching
Core Design Contradiction:
Ease of operationVSDifficulty of detecting and measuring

Solution Approach 1:

The fingerprint recognition process is segmented into distinct stages: fingerprint image capture, feature extraction (identifying ridges, valleys, and minutiae points), template matching against pre-stored patterns, and command execution. This segmentation allows each stage to be optimized independently, making the overall complex process manageable and efficient.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent replaces manual mechanical touch operations with an automated optical/biological recognition system. Instead of requiring users to physically touch multiple screen locations to input commands, the system uses fingerprint image processing and pattern recognition algorithms to automatically identify the user and execute the associated control function.

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