Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If wireless transmission of electrical measurements is used, then data can be transmitted without physical connections, but transmission reliability deteriorates due to obstacles and interference

Engineering Contradiction:
Improvewireless transmission capabilityVSAvoiddata transmission reliability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent introduces a verification device as an intermediary component between the electrical measurement device and the control system. This verification device receives electrical measurements wirelessly, verifies their authenticity and relevance, and then forwards verified measurements to the control system. This mediator approach maintains wireless transmission benefits while improving reliability by filtering out erroneous or irrelevant data caused by obstacles and interference.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Loss of information

If electrical measurements are transmitted to all devices, then all devices receive data, but incorrect or irrelevant information is received leading to undesirable control actions

Engineering Contradiction:
Improvedata completenessVSAvoiderroneous and irrelevant information reception
Core Design Contradiction:
Loss of informationVSObject-affected harmful factors

Solution Approach 1:

The verification device applies local quality by performing location-based verification of electrical measurements. It determines whether each measurement is relevant to the specific geographic location and context of the receiving device. This selective verification ensures that each device receives only locally relevant measurements, preventing erroneous or irrelevant information from causing undesirable control actions while maintaining complete and accurate data transmission.

Inventive Principle:
Principle #3Local quality

3Measurement precision

If verification of electrical measurements is implemented, then accuracy of control actions improves, but system complexity increases

Engineering Contradiction:
Improveelectrical measurement accuracyVSAvoidcommunication system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The verification device operates autonomously using self-service principles. It independently verifies the authenticity and relevance of received electrical measurements using pre-stored verification data and location information, without requiring manual intervention or complex external verification systems. This self-verification capability improves measurement accuracy while minimizing system complexity by using straightforward comparison and filtering logic.

Inventive Principle:
Principle #25Self-service
