Tapered RFID Tag Base for Secure Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing contactless data carriers for object connection devices are not firmly fixed and can easily disengage from the receiving portions, making it difficult to maintain reliable data storage and retrieval.
Innovation Solution
A contactless data carrier design featuring a base with an upper and lower section that gradually decrease in width, made of elastic materials, which abuts firmly against the inner surface of the receiving portion, combined with a tag member for storing and reading data using RFID technology, ensuring secure attachment and easy data access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the data carrier is fixed by generating friction between a load-receiving part and retaining ribs extending perpendicular to the surface, then the data carrier can be attached to the object connection device, but the fixation is not firm and the data carrier may disengage easily
Solution Approach 1:
The base is designed with a tapered geometry where the width gradually decreases from the upper section to the lower section, creating a conical or frustoconical shape. This curved/tapered surface allows the outer peripheral surface of the base to abut firmly against the inner surface of the receiving portion, distributing the fixation force along the tapered interface rather than at a single point, thereby significantly improving both fixation reliability and strength.
Solution Approach 2:
The invention changes the geometric parameters of the base by implementing a tapered width profile instead of a uniform or ribbed structure. The gradual width reduction creates a self-locking effect where the expanding inner surface of the receiving portion generates frictional and normal forces that firmly secure the base, preventing disengagement while maintaining reliable fixation.
2Ease of manufacture
If the retaining ribs extend in a direction parallel to the disengagement force, then the data carrier can be attached, but the attachment becomes loose and prone to disengagement
Solution Approach 1:
Replacing the ribbed structure with a continuously tapered surface eliminates the need for complex rib geometries while achieving superior attachment reliability. The tapered shape is simple to manufacture through common processes like injection molding or machining, and provides continuous surface contact for firm fixation.
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
The design ensures the contactless data carrier remains securely attached to the object connection device, preventing easy disengagement and allowing for reliable, contactless data storage and retrieval, while accommodating various types of receiving portions and object connection devices.
Implementation Method 1
The base has an upper section and a lower section, which are connected to each other. A width of the upper section gradually decreases in a direction away from the lower section, and a width of the lower section gradually decreases in a direction away from the upper section.

AI summary
A contactless data carrier adapted to be disposed in a receiving portion of an object connection device includes a base and a tag member. The base is adapted to be tucked into the receiving portion and has an upper section and a lower section, which are connected to each other. An outer peripheral surface of the base is adapted to abut against an inner surface of the receiving portion. A width of the upper section gradually decreases in a direction away from the lower section. A width of the lower section gradually decreases in a direction away from the upper section. The tag member disposed at the base is stored with data relative to the object connection device to be read in a contactless manner by a reading device.
