Solution Overview
Problem
Existing set-up parts for machines in the filling and bottle manufacturing industry lack a reliable and compact identification method that ensures clear identification during installation and removal, particularly without the need for additional power sources or vulnerable cabling.
Innovation Solution
The use of a piezoelectric transmitter activated by forces during installation and removal, which provides a wireless identification signal using a stable piezoelectric crystal like α-quartz or gallium orthophosphate, eliminating the need for batteries and preventing accidental activation through a protection mechanism, allowing for energy storage and delayed signal transmission.
Engineering Contradictions & Design Principles
Engineering 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
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.
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.
2Ease of operation
If piezoelectric transmitters are activated during installation, then wireless identification is achieved, but accidental activation may occur during normal operation
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.
3Adaptability or versatility
If energy storage devices are added to delay signal transmission, then flexible reading timing is achieved, but device complexity increases
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.
