Dual Cartridge Memory Segmentation for Power-Constrained RFID
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing track density and memory size of magnetic recording medium cartridges lead to higher power consumption, limiting the electric power that can be extracted from antennas, necessitating a solution to enhance memory capacity while maintaining stable communication with readers/writers.
Innovation Solution
The implementation of a dual cartridge memory system, where a first cartridge memory stores management information and operates under limited magnetic field strength for stable communication, and a second cartridge memory with larger capacity stores additional information, readable via a different communication device, allowing for increased total memory capacity without increasing the first memory's size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the memory size of the cartridge memory is increased to increase capacity, then the storage capacity is improved, but the power consumption increases and stable communication cannot be ensured under limited magnetic field strength
Solution Approach 1:
The cartridge memory is divided into two separate memory units: a first cartridge memory (RFID tag) for storing management information and a second cartridge memory for storing additional information. This segmentation allows each memory unit to have optimized power consumption characteristics, enabling the first memory to maintain stable communication under limited magnetic field strength while the second memory provides additional storage capacity.
2Quantity of substance
If the memory size of the cartridge memory is increased to increase capacity, then the storage capacity is improved, but the communication stability deteriorates under constant magnetic field strength
Solution Approach 1:
The cartridge memory is divided into two separate memory units: a first cartridge memory (RFID tag) for storing management information and a second cartridge memory for storing additional information. This segmentation allows each memory unit to have optimized power consumption characteristics, enabling the first memory to maintain stable communication under limited magnetic field strength while the second memory provides additional storage capacity.
3Quantity of substance
If the memory size of the cartridge memory is increased to increase capacity, then the storage capacity is improved, but the electric power extractable from the antenna becomes insufficient
Solution Approach 1:
The cartridge memory is divided into two separate memory units: a first cartridge memory (RFID tag) for storing management information and a second cartridge memory for storing additional information. This segmentation allows each memory unit to have optimized power consumption characteristics, enabling the first memory to maintain stable communication under limited magnetic field strength while the second memory provides additional storage capacity.
