Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If wired or infrared connections are used for configuration, then connection reliability is improved, but device complexity and ease of operation deteriorate

Engineering Contradiction:
Improveconnection reliabilityVSAvoidconnection complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces wired mechanical connections and infrared optical connections with wireless electromagnetic communication (WiFi, Bluetooth). This substitution eliminates physical connection requirements while maintaining communication reliability through standardized wireless protocols, thereby reducing installation complexity and improving user accessibility.

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

Solution Approach 2:

The patent introduces a pairing code mechanism as an intermediary authentication layer during the wireless connection establishment. This pairing code serves as a mediator that ensures secure and reliable connection initialization between the control unit and configuration device, preventing unauthorized connections while simplifying the overall connection process.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If service devices are used for configuration, then connection security is improved, but ease of operation deteriorates

Engineering Contradiction:
Improveconnection securityVSAvoidconfiguration ease
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent enables the control unit to perform self-identification and self-pairing functions. The control unit automatically generates and displays pairing codes, and the configuration device can automatically search and connect to available control units. This self-service capability eliminates the need for specialized service devices while maintaining connection security through automated authentication mechanisms.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent makes standard computers, smartphones, or tablets universal configuration devices that can work with any control unit in the system. By using standard wireless communication interfaces and pairing mechanisms, any user device can serve as a configuration tool, eliminating the need for proprietary service devices and significantly improving operational ease.

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

3Ease of operation

If wireless communication is used for connection, then ease of operation is improved, but reliability deteriorates

Engineering Contradiction:
Improveconnection easeVSAvoidconnection stability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent introduces pairing codes as an intermediary authentication mechanism that establishes secure wireless connections. The pairing code verification process ensures that only authorized devices can connect, preventing unauthorized access and maintaining connection integrity. This intermediary layer compensates for the inherent security vulnerabilities of wireless communication while preserving ease of operation.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent implements feedback mechanisms where the control unit and configuration device exchange pairing codes and connection status information. The system provides real-time feedback on connection establishment, authentication status, and configuration progress. This feedback loop ensures reliable connection management by allowing users to verify successful pairing and troubleshoot connection issues.

Inventive Principle:
Principle #23Feedback
