Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
RFID tags often require over-designing to accommodate extreme scanning scenarios, leading to increased costs and inefficiencies, as they need to maintain reliable communication over varying distances and conditions, which is not effectively addressed by current technologies.
Innovation Solution
A combined RFID tag assembly is created by connecting the antennas of two RFID tags through a conductive path, allowing them to form a circuit that increases the initial range of each tag, enabling longer and more reliable communication links without the need for over-designing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If RFID tags are over-designed to work in extreme scanning scenarios, then reliability is improved, but cost increases significantly
Solution Approach 1:
The patent combines multiple RFID tags into a single assembly where the antennas of individual tags are connected through conductive paths. This merging allows the tags to function collectively as a larger antenna system, extending the reading range without requiring each individual tag to be over-designed for extreme scenarios. The collective antenna system provides enhanced reliability for far-away scanning while keeping individual tag complexity and cost low.
2Length of stationary object
If RFID tags are designed for far-away scanning, then reading range is improved, but the tags cannot be effectively used for individual scanning at close range
Solution Approach 1:
The RFID tag assembly provides dynamic adaptability by allowing flexible configuration of conductive paths between antennas. Depending on the scanning scenario, different conductive path configurations can be activated - connecting antennas for far-away scanning or leaving them separate for individual close-range scanning. This dynamic reconfiguration capability enables the system to adapt to different operational requirements without compromising performance in either scenario.
3Area of moving object
If multiple RFID tags are connected through conductive paths, then antenna size is effectively increased, but device complexity increases
Solution Approach 1:
The patent segments the antenna system into multiple independent RFID tags that can be individually manufactured and then combined. Each tag maintains its own complete antenna structure, but when assembled together with conductive paths, they function as a larger collective antenna. This segmentation approach allows for simplified individual tag design while achieving large effective antenna area through modular assembly, reducing the complexity of manufacturing and testing each component.

Data Source
AI summary
RFID tags are combined in increase their range. A first RFID tag comprises a first chip and a first antenna configured to transmit data from the chip. The first RFID tag has a first initial range by which data may be obtained by an RFID reader from the first chip. A second RFID tag comprises a second chip and a second antenna configured to transmit data from the chip. The second RFID tag has a second initial range by which data may be obtained by an RFID reader from the second chip. A conductive path from first antenna to the second antenna is established to change initial ranges to modified ranges which are greater than the initial ranges.
