Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing detection methods for determining the coupling state of connection apparatuses are complex, unsafe, and unreliable, lacking a simple and reliable means to confirm a final assembly position.
Innovation Solution
A detection apparatus using an RFID tag with a signal device that indicates a digital change of state through a detection signal, either deactivation (1 to 0) or activation (0 to 1), integrated into connection apparatuses via a conduction portion with a target breaking point, allowing easy integration and confirmation of a final assembly position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing detection methods are used to determine the coupling state of connection apparatuses, then detection capability is provided, but the system becomes complex, unsafe, and unreliable
Solution Approach 1:
The patent extracts the detection function from complex existing systems and implements it through a simple RFID tag with a conduction portion that can be severed. The RFID tag contains only the essential elements (antenna, chip, conduction portion) needed for detection, removing unnecessary complexity from the overall system while maintaining reliable coupling state determination.
Solution Approach 2:
The patent employs a disposable RFID tag with a conduction portion designed to be severed during the coupling process. This low-cost, single-use component provides reliable detection without the need for complex, expensive, or reusable detection systems. The tag is discarded after serving its detection purpose, simplifying the overall system architecture.
2Ease of manufacture
If a simple detection method is implemented, then ease of manufacture is improved, but detection reliability may be compromised
Solution Approach 1:
The patent merges the detection function with the coupling process itself by integrating the RFID tag into the connection apparatus. The conduction portion is physically connected to the antenna and chip, and its severing during coupling simultaneously indicates the coupled state. This integration eliminates separate detection components, simplifying manufacture while ensuring reliable detection through the inherent connection state.

Function Achieved in This Case
Provides a simple, safe, and reliable method to determine whether a final assembly position has been achieved, suitable for various types of connections, including fluids, gases, power, and data lines, with a cost-effective and efficient production process.
Implementation Method 1
RFID (radio frequency identification) refers to a technology for transmitter-receiver systems for automatically and contactlessly identifying and locating objects and living beings with radio waves.
Implementation Method 2
The coupling is done by magnetic alternating fields produced by the reader device in a short range or by high-frequency radio waves.

AI summary
According to the disclosure, a detection apparatus for detecting a coupling state of a connection apparatus having a first and a second element to be connected to one another is provided. It comprises a signal device, wherein the signal device is configured such that the signal device indicates a digital change of state by means of a detection signal, in that an existing signal is deactivated and thus in particular a switch from 1 to 0 (deactivation) occurs or a signal is activated or produced and thus in particular a change from 0 to 1 (activation) occurs when a complete coupling of a first and a second element of a connection apparatus is achieved, so that, due to an omission of the signal or the newly produced signal, the detection signal is produced which indicates whether a final assembly position is achieved.
