Cable RFID Tag Structure for Collision-Resistant Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional disposable tags, such as lead seals, are prone to damage and detachment in harsh environments due to collisions with moving machines or hard objects, compromising their functionality and security.
Innovation Solution
A cable-type radio frequency identification tag design featuring a cable clamp with a ratchet gear and a protective case made of harder materials, such as stainless steel, to prevent damage and ensure secure fixation of the cable, incorporating a radio frequency identification rivet for data storage and retrieval.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional lead seal made of soft materials is used, then the tag can be easily installed and disposed, but the tag is easily damaged by collision in harsh environments
Solution Approach 1:
The clamp body is constructed from composite materials with different hardness levels: the outer protective layer is made of hard material (hardness 50-80 on the Vickers scale) to resist collision damage, while the inner layer is made of soft material (hardness 10-30 on the Vickers scale) to provide cushioning and ease of installation. This composite structure resolves the contradiction between collision resistance and ease of installation by combining the advantages of both hard and soft materials.
2Ease of manufacture
If conventional lead seal with single hardness material is used, then the manufacturing process is simple, but the tag lacks resistance to collision in harsh environments
Solution Approach 1:
The clamp body uses a composite structure with an outer hard layer and inner soft layer, providing collision resistance while maintaining manufacturability through standardized manufacturing processes for composite structures.
Solution Approach 2:
Different regions of the clamp body have different material properties optimized for their specific functions: the outer surface facing collision risks uses hard material for protection, while the inner region contacting the cable uses soft material for gentle gripping and ease of installation. This local differentiation of material quality addresses the contradiction between manufacturing simplicity and collision resistance.
3Reliability
If the cable clamp is made of hard material to resist collision, then the collision resistance is improved, but the cable clamp may damage the cable during installation
Solution Approach 1:
The clamp body combines an outer hard layer for collision resistance with an inner soft layer that gently contacts the cable during installation and operation. This composite material structure prevents cable damage while maintaining collision resistance, as the soft inner layer acts as a protective interface between the hard outer shell and the cable.
Solution Approach 2:
The material properties are locally optimized: the outer surface is hard to resist external collisions, while the inner surface contacting the cable is soft to prevent cable damage during installation and operation. This local quality differentiation resolves the contradiction between collision resistance and cable protection.

AI summary
A cable-type radio frequency identification tag includes a cable clamp having a fixing hole and a through hole. A receiving space for receiving a ratchet gear is provided beside the through hole. A pin hole penetrates through two opposite surfaces of a clamp body. A protecting case harder than the cable clamp is wrapped around the cable clamp and includes a case body and a cover plate. A rivet body is riveted on the case body, a hole of the cover plate, and the pin hole of the cable clamp and has a head portion. A radio frequency identification block fits in a counterbore of the head portion. A cable is fixed in the fixing hole. A free end of the cable penetrates through the through hole to be fixed by the ratchet gear to form a fitting ring.
