Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sample preparation methods for complex molecules, such as biomolecules, are labor-intensive, time-consuming, and require multiple steps, leading to variability and equipment investment, which is often limited to high-volume testing laboratories.
Innovation Solution
Encapsulated workflow reagents are used, which are stabilized by an encapsulating material and attached to a scaffolding material, allowing controlled release at specific points in the workflow process, reducing the need for manual handling and equipment investment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual sample preparation and reagent mixing are used, then operational flexibility is maintained, but time consumption increases and precision decreases
Solution Approach 1:
The patent applies preliminary action by pre-encapsulating reagents in microcapsules before sample analysis. The microcapsules contain pre-measured reagent quantities and are designed to dissolve or rupture upon contact with the sample, automatically performing the mixing function without manual intervention. This pre-preparation eliminates time-consuming manual reagent handling during the actual analysis process.
Solution Approach 2:
The microcapsules are designed to self-activate upon contact with the sample matrix, automatically releasing and mixing reagents without external control. The capsule structure itself provides the mixing mechanism through dissolution or rupture, making the system self-sufficient and eliminating the need for manual operation while maintaining precision through consistent pre-encapsulated reagent quantities.
2Adaptability or versatility
If multiple separate devices are used for sample preparation, then functional specialization is achieved, but device complexity increases
Solution Approach 1:
The patent merges multiple sample preparation functions into a single integrated flow-through device. The device combines sample injection, microcapsule dissolution, reagent mixing, and chromatographic separation in one continuous flow path. This integration eliminates the need for multiple separate devices while maintaining functional versatility through modular cartridge designs that can be configured for different analytical workflows.
Solution Approach 2:
The flow-through device is designed with universal functionality to perform multiple sample preparation tasks using the same basic platform. Different microcapsule formulations and flow path configurations allow the single device to handle various sample types and analytical requirements, replacing multiple specialized devices with one multi-functional system.
3Manufacturing precision
If reagents are prepared manually, then cost is reduced, but manufacturing precision decreases
Solution Approach 1:
The patent segments the reagent system into individual microcapsules, each containing a precise pre-measured amount of reagent. This segmentation allows for automated manufacturing of uniform capsules with controlled reagent loading, achieving high precision through consistent capsule production rather than manual measurement. The segmented approach enables automated quality control during capsule manufacturing.
Solution Approach 2:
The invention changes the physical state and delivery mechanism of reagents from manual liquid handling to pre-encapsulated solid or suspended forms. This parameter change enables automated capsule filling and sealing processes that achieve higher precision than manual pipetting, while the encapsulation technology itself provides precise reagent containment and controlled release characteristics.
