Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If electronic signature processing is implemented, then productivity and digitization are improved, but usability and user acceptance deteriorate due to complexity and security concerns

Engineering Contradiction:

Improvedigitization efficiencyVSAvoiduser acceptance

Core Design Contradiction:

ProductivityVSEase of operation

Solution Approach 1:

The system performs automatic authentication by acquiring personal identifiable information from the portable storage medium and comparing it with information from sensors mounted on the terminal. The authentication process occurs without requiring user intervention beyond inserting the storage medium, allowing the system to serve itself in verifying identity and executing predetermined processing.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces manual paper document handling with automated electronic processing. Instead of physical paper submission, the system uses electronic data transmission and automated authentication mechanisms, substituting mechanical paper-based operations with digital processes that improve productivity while maintaining ease of use through automation.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Ease of operation

If traditional paper document submission is used, then ease of operation is maintained, but productivity and security are reduced

Engineering Contradiction:

ImprovesimplicityVSAvoidprocessing efficiency

Core Design Contradiction:

Ease of operationVSProductivity

Solution Approach 1:

The system replaces paper document handling with electronic data processing. Personal identifiable information is automatically read from portable storage media and verified through sensor-based authentication, eliminating the need for physical paper submission while maintaining operational simplicity for users.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The automated authentication system performs verification without requiring users to manually complete forms or undergo complex procedures. The system self-services by automatically acquiring information from the portable storage medium, comparing it with sensor data, and executing processing based on authentication results, thereby improving productivity while keeping the user experience simple.

Inventive Principle:

Principle #25Self-service

3Ease of operation

If manual authentication processes are used, then ease of operation is maintained, but security and reliability deteriorate

Engineering Contradiction:

Improveoperational simplicityVSAvoidsecurity

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The system replaces manual authentication with automated biometric verification. Sensors mounted on the terminal capture personal identifiable information and compare it with data from portable storage media, eliminating manual authentication processes while enhancing security through objective, automated verification that reduces human error and fraud risk.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The authentication system incorporates feedback mechanisms by comparing information from the portable storage medium with data acquired from sensors. The system provides immediate authentication results and executes predetermined processing based on the verification outcome, creating a closed-loop system that enhances security through automated decision-making while maintaining operational simplicity.

Inventive Principle:

Principle #23Feedback
