Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing state recognition tags fail to effectively recognize separation states between a tag main body and a tag fragment, and cannot change information transmitted to a tag reader/writer accordingly, limiting their functionality and usability.
Innovation Solution
A state recognition tag system comprising a tag main body and a tag fragment, each with dedicated information holding, separation-state recognizing, and control units, allowing for the determination and transmission of appropriate information based on their separation state, enabling both components to function as tags and provide different information depending on their connection status.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the tag main body and tag fragment are separated, then the tag can provide different information for separated states, but the existing tags cannot recognize the separation state or change transmitted information accordingly
Solution Approach 1:
The patent implements feedback mechanisms where the tag main body and tag fragment continuously monitor their connection state through electrical contact detection. When separation occurs, the change in electrical contact state is detected and fed back to the control unit, which then automatically switches the transmitted information from integrated article information to separate component information, ensuring reliable state recognition and appropriate information adaptation.
Solution Approach 2:
The tag system performs self-service by automatically detecting its own separation state through built-in electrical contact sensors and autonomously selecting which information to transmit without external intervention. The tag main body and fragment each have embedded sensors that monitor their mutual connection state and self-determine the appropriate information transmission mode based on whether they are connected or separated.
2Adaptability or versatility
If both tag main body and tag fragment function as independent tags after separation, then information suitability for present state is improved, but device complexity increases
Solution Approach 1:
The patent divides the tag into two separable functional units: a tag main body and a tag fragment. Each unit contains essential tag components (information storage, transmission, and control elements) enabling independent functionality when separated. The segmentation allows each part to operate as a standalone tag while maintaining the ability to function as an integrated system when connected, providing versatility without requiring completely separate complex systems.
Solution Approach 2:
The tag main body and tag fragment are designed with universal functionality, where each unit can operate independently as a complete tag or work together as an integrated article tag. Both units contain necessary components for information storage, transmission, and state detection, allowing them to perform multiple functions: individual component tracking when separated and integrated article tracking when connected, reducing the need for different specialized systems.
3Measurement precision
If electrical contact state is used to determine separation, then separation detection accuracy is improved, but the tag requires additional sensing components
Solution Approach 1:
The patent merges the electrical contact sensing function with the existing electrical connection pathways used for power and data transmission. The same conductive traces and contact points that enable electrical communication between the tag main body and fragment also serve as the sensing elements for detecting separation state. This integration eliminates the need for separate sensing components, achieving accurate separation detection while minimizing additional hardware complexity.

AI summary
A state recognition tag is configured to include a tag main body, and a tag fragment separable from the tag main body, and each of the tag main body and the tag fragment is provided with an information holding unit storing therein information to be transmitted, a separation-state recognizing unit which recognizes a separation state between the tag main body and the tag fragment, a control unit which exercises transmission control for transmitting the information from the information holding unit based on the separation state, and an electric power supplying unit which supplies electric power to the information holding unit, the separation-state recognizing unit, and the control unit. Regardless of whether the tag main body and the tag fragment are connected to each other or separated from each other, both the tag main body and the tag fragment can function as tags as needed. Furthermore, different information can be provided to a user according to the separation state between the tag main body and the tag fragment.
