Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a system designer manually selects associated function elements based on system configuration knowledge, then the security function can be implemented, but the design effort and time required increase significantly

Engineering Contradiction:

Improvesecurity function implementationVSAvoiddesign effort

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The security design support device automatically generates a list of candidate associated function elements by self-evaluating the system configuration data, eliminating the need for designers to manually determine which function elements are needed. The system serves itself by autonomously analyzing the system configuration and producing the candidate list.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces the manual mechanical process of designer analysis and selection with an automated information processing system. The device uses computer-based algorithms to evaluate system configuration data and generate candidate associated function elements, substituting human cognitive effort with automated computational processes.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Ease of operation

If existing security-design support methods are used, then security-function requirements can be arranged, but the appropriateness of associated function elements cannot be determined

Engineering Contradiction:

Improvesecurity-function requirement arrangementVSAvoidappropriateness determination

Core Design Contradiction:

Ease of operationVSMeasurement precision

Solution Approach 1:

The device provides feedback by evaluating each candidate associated function element against the system configuration data and presenting appropriateness information to the designer. This feedback loop allows the system to not only generate candidates but also assess their suitability, enabling informed selection decisions.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent adds a new dimension of evaluation by introducing appropriateness assessment based on system configuration matching. This transforms the selection process from a single-dimensional arrangement task to a multi-dimensional evaluation that considers both the security function requirements and the specific system configuration context.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

3Productivity

If associated function elements are not sufficiently designed, then the system can be implemented quickly, but security accidents may occur

Engineering Contradiction:

Improvesystem implementation speedVSAvoidsecurity accidents

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The device performs preliminary evaluation and identification of candidate associated function elements before the actual security implementation. By pre-analyzing the system configuration and generating a candidate list with appropriateness assessments, the system ensures that necessary security elements are identified in advance, preventing security accidents while maintaining implementation speed.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The security design support device acts as an intermediary between the system configuration and the security implementation. It mediates by translating system configuration data into a structured list of candidate associated function elements with appropriateness evaluations, ensuring that no critical security elements are overlooked while streamlining the implementation process.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A display unit displays a configuration of a system in a display device. An implementation scheme configuration support unit provides a candidate of a security implementation scheme configurable for a component of the system and configures a security implementation scheme selected by a user to a component selected by a user. An associated function element configuration support unit provides a candidate of an associated function element configurable for a component of the system and configures an associated function element selected by a user to a component selected by a user. An evaluation unit determines whether or not the associated function element configured for the component of the system is appropriate based on a condition to determine appropriateness of the configuration of the certain associated function element. An output unit outputs a result of the determination by the associated function element evaluation unit.
