Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional identification elements (bar codes, transponders with batteries) are used, then identification capability is achieved, but device complexity and reliability deteriorate due to additional power sources and vulnerable cabling

Engineering Contradiction:
Improveidentification reliabilityVSAvoidpower supply complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The piezoelectric transmitter generates its own operating energy from the mechanical installation process itself, eliminating the need for external power sources, batteries, or cabling. The system serves itself by converting the installation forces into electrical energy for signal transmission.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The invention extracts and eliminates the complex power supply system (batteries, capacitors, cabling) from the identification element, retaining only the essential identification function powered by the piezoelectric effect during installation.

Inventive Principle:
Principle #2Taking out (Extraction)

2Ease of operation

If piezoelectric transmitters are activated during installation, then wireless identification is achieved, but accidental activation may occur during normal operation

Engineering Contradiction:
Improveidentification convenienceVSAvoidfalse signal prevention
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The protection mechanism dynamically adjusts the activation state of the piezoelectric transmitter, keeping it inactive during normal machine operation and only enabling it during the specific dynamic event of installation or removal, thus preventing false signals while maintaining identification capability.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If energy storage devices are added to delay signal transmission, then flexible reading timing is achieved, but device complexity increases

Engineering Contradiction:
Improvesignal reading flexibilityVSAvoidenergy storage complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The piezoelectric transmitter stores the generated energy in an integrated capacitor during installation, preparing it in advance for later signal transmission. This preliminary energy storage enables flexible reading timing without adding complex external power management systems.

Inventive Principle:
Principle #10Preliminary action
