RFID IC Pin Coupling for Dynamic ID Generation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current RFID technologies require separate RFID chips for each product, leading to inefficiencies and waste due to fixed IDs, as each product may have different sales statuses and consumption patterns.
Innovation Solution
An RFID integrated circuit design that reduces pin counts by using a resonant coil and capacitor, allowing IDs to be dynamically changed through external circuits, enabling each pin to couple with the coil and capacitor differently to generate various IDs, thus allowing a single production line to produce multiple ID variations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate RFID chips with fixed IDs are produced for each product, then each product can be identified uniquely, but production complexity increases and waste occurs due to different sales statuses
Solution Approach 1:
The patent implements dynamic ID configuration by allowing the RFID chip's ID to be changed through external circuit connections (pin coupling to resonant coil/capacitor) after production. This transforms the static ID assignment into a dynamic system where the same physical chip can serve multiple product identities, eliminating the need for multiple production lines while maintaining unique identification reliability.
Solution Approach 2:
The RFID chip is designed with universal functionality to operate with different ID configurations by connecting different pins to the resonant coil and capacitor. A single chip design can be adapted to multiple product types through external circuit configuration, making the chip multi-functional and eliminating the need for product-specific chip variants.
2Adaptability or versatility
If multiple RFID chip variants with different IDs are produced, then different product requirements are met, but manufacturing waste increases due to unsold products
Solution Approach 1:
The system performs preliminary configuration setup by establishing the relationship between pin connections and ID values during the design phase. The actual ID assignment is deferred to the application phase through external circuit configuration, allowing flexible adaptation without producing multiple chip variants in advance, thus preventing waste from unsold product-specific chips.
Solution Approach 2:
The patent changes the ID parameter dynamically through external circuit configuration rather than through physical chip differentiation. By modifying which pin is coupled to the resonant coil and capacitor, the system changes the effective ID parameter of the RFID chip, enabling the same physical chip to adapt to different product requirements without producing waste.
3Ease of manufacture
If RFID chips have fixed IDs after production, then manufacturing is simplified, but flexibility to accommodate different sales statuses is reduced
Solution Approach 1:
The patent introduces an intermediary configuration layer between the physical chip and the product identification requirement. The external circuit connection (pin coupling to resonant elements) serves as the intermediary that translates a single physical chip into multiple logical ID configurations, maintaining manufacturing simplicity while achieving configuration flexibility.
Solution Approach 2:
The patent adds a configuration dimension to the RFID chip system by introducing external circuit connectivity as a new degree of freedom. Instead of varying chips in the physical manufacturing dimension, the system varies ID configuration in the circuit connection dimension, allowing flexible adaptation without complicating the manufacturing process.
