Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional access control methods are used for maintenance, then ease of operation is maintained, but reliability of access control deteriorates due to unauthorized access and improper maintenance

Engineering Contradiction:

Improveaccess control reliabilityVSAvoidmaintenance access convenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces traditional mechanical access control methods (physical keys, manual authorization) with wireless communication technology. The wireless communicator enables contactless authentication between maintenance personnel and electronics units, eliminating the need for physical interaction while enhancing access control reliability and maintaining operational convenience.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces a wireless communicator as an intermediary device that facilitates secure communication between maintenance personnel and electronics units. This intermediary enables automated authentication and authorization processes, improving reliability by ensuring only authorized personnel can access units while maintaining ease of operation through streamlined workflows.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If manual access control procedures are implemented, then device complexity is minimized, but productivity of maintenance operations deteriorates due to time-consuming authentication processes

Engineering Contradiction:

Improvemaintenance operation efficiencyVSAvoidaccess control system complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent implements self-service functionality where the wireless communicator automatically performs authentication and authorization without requiring manual intervention from administrators. The system autonomously verifies credentials, manages access rights, and logs maintenance activities, significantly improving productivity while the standardized wireless protocol keeps system complexity manageable.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent performs preliminary authentication and authorization actions before maintenance operations begin. The wireless communicator pre-verify credentials and establish access permissions in advance, enabling maintenance personnel to immediately begin work without time-consuming procedural steps, thereby enhancing productivity with minimal added complexity.

Inventive Principle:

Principle #10Preliminary action

3Reliability

If wireless communication technology is implemented for maintenance access control, then reliability of access control improves through automated authentication, but device complexity increases due to additional wireless communication components

Engineering Contradiction:

Improveaccess control securityVSAvoidelectronics unit structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent designs the wireless communicator to serve multiple functions: authentication, authorization, communication, and logging. By consolidating these functions into a single integrated component, the system achieves high reliability through automated security processes while minimizing the increase in device complexity through functional consolidation rather than adding separate components for each function.

Inventive Principle:

Principle #6Universality (Multi-functionality)
