Magnetic Barcode Manipulation Using Spatio-Temporal Field Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing magnetic manipulation systems lack selectivity, as they manipulate all magnetic structures, making it difficult to selectively target magnetically-barcoded materials from background magnetic materials.
Innovation Solution
The system employs magnetically-barcoded materials with layers of magnetic anisotropy, which are selectively manipulated using a magnetic platform that generates spatio-temporal magnetic fields matching the barcode, enabling a "lock-key" interaction for selective manipulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional magnetic manipulation systems are used, then magnetic structures can be manipulated, but selectivity is lost as all magnetic structures are manipulated indiscriminately
Solution Approach 1:
The patent segments the magnetic field manipulation into multiple independent components by using an array of independently controllable magnetic elements (coils or permanent magnets). Each element can be individually addressed and controlled, allowing selective manipulation of specific magnetic barcodes while leaving others unaffected. This segmentation enables precise spatial and temporal control over magnetic field application.
Solution Approach 2:
The patent implements local quality by creating spatially varying magnetic field patterns that match specific barcode configurations. Each magnetic element in the array can generate localized field patterns with unique characteristics (strength, direction, temporal variation) that correspond to specific barcode sequences. This allows the system to differentiate between and selectively manipulate different magnetic barcodes based on their local magnetic properties.
2Reliability
If simple magnetic manipulation is used, then the system is easy to operate, but it cannot selectively target specific magnetically-barcoded materials from background materials
Solution Approach 1:
The patent employs dynamic control of magnetic field parameters (strength, direction, temporal variation) to achieve selectivity. The magnetic elements can be activated or deactivated dynamically, and their field characteristics can be modulated in real-time. This dynamic capability allows the system to create time-varying field patterns that selectively interact with specific barcode sequences, enabling discrimination between target and background materials.
Solution Approach 2:
The patent utilizes parameter changes in the magnetic field (amplitude, frequency, phase, spatial distribution) to achieve selective manipulation. By varying these parameters across different magnetic elements and time, the system can create unique field signatures that match specific barcode configurations. This parameter control enables selective targeting without requiring fundamentally different physical mechanisms.

AI summary
Embodiments herein are directed to a system and a method of selectively manipulating magnetically-barcoded materials from background magnetic materials. Magnetic barcodes include layers of magnetic anisotropy. These are then manipulated by a magnetic system that can drive spatio-temporal magnetic fields that can “match” a barcode to drive a specific interaction, thereby providing a “lock-key” interaction. This technique is able to selectively manipulate magnetically-barcoded materials, and can have applications across a variety of magnetic systems such as cell separation, drug delivery, valves, and motors.
