Strapping Tool Module Identification via NFC Transponder
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing strapping tools lack a clear and secure association between modular elements and the tool itself, making it difficult to change the application field or mode of operation and manage module replacement effectively.
Innovation Solution
A strapping tool with a removable module that includes a transponder for wireless communication with a reader on the base, enabling both mechanical and data connectivity, allowing for secure and unambiguous identification and pairing of modules with the drive, using NFC technology for data exchange and energy induction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If modular elements are made interchangeable and removable, then adaptability and ease of repair are improved, but reliability and secure association between elements and tool deteriorate
Solution Approach 1:
The patent replaces mechanical association methods with an electronic data-based system. A transponder (electronic component) stores identification data that is read by a reader, creating a secure digital link between the module and tool. This electronic substitution ensures reliable pairing without relying solely on mechanical interlocking, thus maintaining adaptability while improving secure association.
2Ease of operation
If mechanical connection alone is used for module replacement, then ease of operation is improved, but loss of information about module identity and compatibility increases
Solution Approach 1:
The patent implements a feedback mechanism where the reader reads identification data from the transponder on the module and sends it back to the control unit. This feedback loop ensures that the system receives confirmation of module identity and compatibility before allowing operation, preventing information loss while maintaining ease of operation through automated verification.
Solution Approach 2:
The transponder is pre-loaded with identification data at the factory, and the reader is pre-programmed with compatibility criteria. This preliminary preparation of data and verification rules enables quick, information-preserving module replacement without requiring complex real-time identification processes, thus maintaining ease of operation while preventing information loss.
3Device complexity
If no electronic identification system is used, then device complexity is reduced, but adaptability and secure module-tool association deteriorate
Solution Approach 1:
The patent extracts the identification and verification functionality into a separate, dedicated electronic component (the transponder). This extraction isolates the complexity of electronic identification into a self-contained module, allowing the main strapping tool to remain relatively simple while gaining advanced adaptability features through the added transponder-reader system.

AI summary
A strapping tool has a tensioner for tightening a strap, a sealer for fixing together ends of the strap, a base, and a drive mounted on the base for operating the tensioner and sealer. The sealer or tensioner is a module removably attached to the base. A transponder is provided on the module and a reader on the base for wirelessly communicating with the transponder. A controller is connected to the reader for operating the tool.
