Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods are inadequate for effectively collecting and deactivating pathogens, such as coronaviruses, within the body, as they lack targeted and efficient mechanisms for localization and inactivation.
Innovation Solution
A magnetic particle device with a fillable section that uses magnetizable materials to attract and immobilize pathogens, employing magnetic fields to guide the device to specific locations within the body, where pathogens are bound, heated, or subjected to destructive forces for inactivation, and subsequently eliminated.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional methods are used to remove pathogens, then the approach is simple, but the effectiveness and targeting capability are insufficient
Solution Approach 1:
The system divides the pathogen removal process into distinct functional segments: magnetic particles for attraction, heating elements for inactivation, and fillable sections for containment. This segmentation allows each component to perform its specific function efficiently while maintaining overall system effectiveness.
Solution Approach 2:
The magnetic particle device integrates multiple functions into a single system: pathogen attraction via magnetic fields, pathogen inactivation via heating, and pathogen containment within fillable sections. This multi-functionality improves removal effectiveness without requiring separate systems for each function.
2Measurement precision
If magnetic particles are used to attract pathogens, then targeting capability improves, but control over particle movement and localization becomes more difficult
Solution Approach 1:
The patent introduces an intermediary control mechanism that mediates between the magnetic field application and particle movement. This intermediary system enables precise localization of magnetic particles to specific body locations while maintaining ease of operation through external field control rather than direct particle manipulation.
3Reliability
If pathogens are heated for inactivation, then pathogen destruction effectiveness improves, but risk of damaging healthy tissues increases
Solution Approach 1:
The heating function is applied with local quality through magnetically-controlled heating elements that can be precisely positioned. This allows high-temperature pathogen inactivation at the target location while keeping surrounding healthy tissues at safe temperatures, thus improving inactivation effectiveness without increasing tissue damage risk.
Solution Approach 2:
The heating system operates dynamically through controlled magnetic field application, enabling temperature regulation that adapts to the specific needs of pathogen inactivation versus tissue protection. This dynamic control maintains high effectiveness for pathogen destruction while minimizing harmful effects on healthy tissues.
4Measurement precision
If magnetic fields are applied to guide particles, then targeted delivery improves, but energy consumption increases
Solution Approach 1:
The magnetic field application uses periodic or pulsed action rather than continuous application. This allows precise targeted delivery of magnetic particles to specific locations while reducing overall energy consumption by applying the field only when and where needed, rather than continuously throughout the entire process.
