Programmable Transponder Inserts for Fastening Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic fastening apparatuses face management challenges due to the need for specific inserts with pre-programmed identification codes, requiring reprogramming of tools when inserts are replaced or new types are introduced, and lack flexibility in adjusting for measurement errors caused by insert-apparatus coupling.
Innovation Solution
An electronic apparatus with interchangeable inserts equipped with transponders that store and transmit setting parameters, allowing for easy correction of measurement errors and eliminating the need for manufacturer-specific codes, enabling flexible use and efficient management by storing correction coefficients directly in the inserts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If inserts are equipped with pre-programmed identification codes stored by the manufacturer, then the apparatus can be automatically set according to preset settings, but the inserts cannot be easily reprogrammed or adapted when replaced or when new types are introduced
Solution Approach 1:
The patent makes the insert's identification code dynamic and programmable. Instead of being fixed during manufacturing, the code can be modified and reprogrammed in the field using a programming device that communicates with the insert's memory, allowing flexible adaptation when inserts are replaced or new types are introduced while maintaining automatic apparatus setting capability
Solution Approach 2:
The patent enables change of the identification code parameter in the insert's memory through external programming. The programming device can write new code values to the insert's memory circuit, allowing the same physical insert to be adapted for different applications or to replace lost/lost inserts without requiring manufacturer reprogramming
2Reliability
If all setting data for various inserts is stored in the apparatus, then the apparatus can find correct parameters when detecting an insert's identification code, but the apparatus becomes complex and requires extensive memory storage
Solution Approach 1:
The patent uses the identification code in the insert as a key to retrieve setting data from the apparatus's stored database. When the transponder transmits the code, the apparatus's microprocessor searches its internal memory for matching setting parameters and automatically configures itself, eliminating the need for extensive manual programming while maintaining reliability
Solution Approach 2:
The identification code acts as an intermediary between the insert and the apparatus's setting data. Rather than storing all possible insert configurations in the insert itself, the code serves as a reference key that links to comprehensive setting data stored in the apparatus, reducing complexity while ensuring correct parameter retrieval
3Adaptability or versatility
If transponders contain apparatus parameter setting data directly, then the inserts are self-contained, but the data must be pre-programmed by the manufacturer with special equipment, leading to greater management problems
Solution Approach 1:
The patent enables the insert to serve itself by allowing field programming of the identification code and setting data using a programming device that can be used by end users without requiring manufacturer intervention. The insert's memory can be written and modified independently, making the system self-sufficient for programming needs

AI summary
An electronic apparatus for controlled fastening, comprises a body (11) coupled to which is one of different removable inserts (17, 17', 17"). The insert comprises a transponder (18) which sends setting signals to the apparatus when it is mounted on the apparatus. The apparatus in turn comprises transmission means for programming into the transponder (18) information which shall be inserted into the signals which shall subsequently be sent by the transponder to the apparatus.
