Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple communication protocols are integrated into the power supply device, then adaptability to different industrial control systems is improved, but device complexity increases

Engineering Contradiction:
Improveadaptability to communication protocolsVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The communication unit is divided into separate, interchangeable communication modules, each supporting a specific communication protocol. This segmentation allows the device to handle multiple protocols without increasing the complexity of the core power supply unit, as each protocol is isolated in its own module.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The communication module is designed as a universal interface that can be configured to support different communication protocols through software configuration rather than hardware changes. This multi-functionality approach allows a single module design to serve multiple protocol requirements.

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

2Adaptability or versatility

If communication modules are made interchangeable and removable, then ease of adaptation to different protocols is improved, but reliability of communication connection may worsen

Engineering Contradiction:
Improveadaptability to communication protocolsVSAvoidreliability of communication connection
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The system performs preliminary detection and configuration when a communication module is inserted. The control electronics automatically detect the inserted module type, retrieve the corresponding communication parameters from the parameter memory, and configure the communication interface before actual communication begins, ensuring reliable connection establishment.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system implements feedback mechanisms where the control electronics continuously monitor the communication connection status and can detect when a module is inserted or removed. This feedback allows the system to dynamically adjust and maintain reliable communication by switching between configured parameters based on the active module.

Inventive Principle:
Principle #23Feedback

3Adaptability or versatility

If software-based control functions are implemented, then updateability and flexibility of device functions are improved, but security risks from unauthorized access increase

Engineering Contradiction:
Improveupdateability of device functionsVSAvoidsecurity risks
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The communication module acts as an intermediary layer between external systems and the control electronics. It provides a controlled interface that mediates access to the device's functions and parameters, allowing software updates and configuration changes while filtering and validating all communications to prevent unauthorized access and security threats.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Ease of operation

If automatic parameter detection and switching are implemented, then ease of operation is improved, but device complexity increases

Engineering Contradiction:
Improveease of configurationVSAvoidcontrol electronics complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The system implements self-service functionality where the control electronics automatically detect the inserted communication module type, retrieve the appropriate communication parameters from the parameter memory, and configure the communication interface without requiring manual intervention. This automation simplifies operation while the complexity is contained within the self-configuration logic.

Inventive Principle:
Principle #25Self-service
