Belt With Embedded RFID Memory For Drive Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing belt drive systems lack assurance of using approved belts, leading to potential operational safety and reliability issues due to unknown speed, tensile force, and wear conditions, and there is a need to ensure only compliant belts are used while maintaining low production costs.
Innovation Solution
A belt with an integrated data memory, specifically an RFID transponder, is embedded in the neutral fiber and carcass area, allowing for electronic identification and verification of belt parameters such as type, manufacturer, and operational limits, which can be read and processed to ensure compliance and prevent faulty belts from being used.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a data memory is integrated in the belt body, then belt identification and verification capability is improved, but device complexity increases
Solution Approach 1:
The data memory is integrated directly into the belt body by embedding it in the rubber matrix during vulcanization, merging the identification function with the belt structure itself rather than adding a separate attachment component
Solution Approach 2:
The integrated data memory serves multiple functions: storing belt identification information, enabling verification against approved belt lists, and providing a basis for recall operations, all within a single compact component
2Strength
If the data memory is arranged in the neutral fiber area, then the belt's mechanical strength is improved, but the data memory protection is worsened
Solution Approach 1:
The data memory is embedded within the rubber matrix material during vulcanization, merging the protective function of the belt material with the data storage function, so the same material that provides mechanical strength also provides protection
Solution Approach 2:
The data memory component is nested within the multi-layer belt structure, specifically positioned in the neutral fiber area and embedded in the rubber matrix, surrounded by multiple layers of belt material that protect it from external harmful factors
3Measurement precision
If an active marking system is used, then position and speed detection is improved, but energy consumption increases
Solution Approach 1:
The passive RFID data memory replaces active marking systems that generate electromagnetic fields or optical beams, eliminating the need for energy-consuming active transmission while enabling verification through passive electronic reading of stored information
Solution Approach 2:
The belt verification system operates passively, allowing the data memory to be read without requiring the belt to actively transmit signals or consume energy, making the verification process energy-independent
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution enhances operational safety and reliability by ensuring only approved belts are used, allows for easy recall of defective batches, and prevents drive movement if parameters are not met, while maintaining low production costs and long service life due to the RFID's passive nature and protective covering.
Implementation Method 1
A data memory is integrated in the belt body, by means of which belt-identifying information can be stored. The data memory is arranged in the area of a neutral fiber and in the area of a carcass
Data Source
AI summary
The invention relates to a belt for transmitting a drive motion, comprising a belt body consisting of an elastic material and a carcass that extends in the longitudinal direction of the belt and that is at least partially surrounded by the belt body for increasing the strength of said belt body in the longitudinal direction of the belt. A data memory for saving data is situated in the belt body and at least one piece of information that identifies the belt is stored in the data memory. The drive motion can be enabled and/or disabled in accordance with the information that identifies the belt.
