Innovation Solution
A high-temperature RFID label is developed, comprising a pressure-sensitive polymeric material, a liner, and an adhesive, with an RFID tag located inside, designed to withstand temperatures above 300°F, featuring a removable liner and suitable adhesives like acrylic or high-heat silicon-based materials, allowing for secure attachment and data tracking on metal products.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional tracking methods are used on high-temperature metal products, then product identification can be maintained, but the tracking system becomes inefficient and costly
Solution Approach 1:
The patent replaces traditional mechanical tracking methods (physical tags, manual recording) with an RFID electromagnetic field-based system. The RFID tag uses electromagnetic induction to communicate product information wirelessly, eliminating the need for mechanical contact or manual intervention during tracking operations, thereby improving both efficiency and reliability at high temperatures
Solution Approach 2:
The patent employs a composite label structure combining polyimide material with RFID technology. The polyimide substrate provides high-temperature resistance while the integrated RFID chip enables electronic tracking, creating a composite solution that maintains identification reliability under extreme conditions while enabling efficient automated tracking
2Ease of operation
If RFID tags are exposed directly on high-temperature products, then data retrieval is easy, but the RFID tag integrity is compromised at temperatures above 300°F
Solution Approach 1:
The patent embeds the RFID tag inside a multi-layer polyimide label structure, which itself is attached to the metal product. This nested configuration protects the RFID tag from direct thermal exposure while maintaining wireless communication capability through the label layers, preserving tag integrity at high temperatures
Solution Approach 2:
The polyimide label acts as an intermediary between the RFID tag and the high-temperature environment. It transmits electromagnetic signals for data retrieval while simultaneously providing thermal protection to the RFID tag, enabling easy data access without compromising tag reliability
3Ease of manufacture
If conventional adhesives are used to attach labels to metal products, then attachment is simple, but the adhesive fails at high temperatures
Solution Approach 1:
The patent specifies using high-temperature resistant adhesives capable of withstanding temperatures above 300°F, fundamentally changing the thermal parameter requirements for the adhesive material. This ensures the adhesive maintains its bonding properties in high-temperature environments while preserving application simplicity
