Solution Overview

Problem

Current methods for studying absorption, transport, and secretion across epithelial tissues are limited by low throughput, difficulty in mounting tissues, and leakage issues, particularly with thick tissues, and do not allow for simultaneous analysis of multiple segments, which hampers the understanding of epithelial function and drug absorption.

Innovation Solution

A device for horizontal mounting of epithelial tissue segments with varying thickness, using a vial assembly with a crimp cap and inert material ring for secure sealing, allowing for medium throughput analysis and simultaneous preparation of multiple samples, reducing contamination risks and tissue stress.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If vertical mounting of epithelial tissue segments is used in traditional chambers, then tissue can be held in place, but the experimental conditions differ substantially from in vivo situation and thick tissues cannot be properly mounted

Engineering Contradiction:
Improvephysiological relevance of experimental conditionsVSAvoiddifficulty in mounting tissue segments
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The invention inverts the traditional vertical mounting approach by implementing horizontal mounting of epithelial tissue segments. The vial assembly with crimp cap and inert material ring creates a horizontal configuration that allows thick tissues to be mounted properly while maintaining physiological relevance, directly addressing the limitation of vertical mounting systems

Inventive Principle:
Principle #13The other way round (Inversion)

2Productivity

If traditional transwell plates are used, then medium throughput studies can be performed, but tissue samples do not sufficiently adhere to membranes causing leakage

Engineering Contradiction:
Improvethroughput of permeation studiesVSAvoidadherence of tissue sample to membrane
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The invention segments the mounting system into distinct functional components: the vial body, the crimp cap, and the inert material ring. This segmentation allows each component to perform its specific function - the crimp cap provides secure closure while the inert material ring ensures proper tissue positioning and adhesion, eliminating leakage issues while maintaining throughput capability

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The inert material ring acts as an intermediary element between the tissue sample and the vial assembly. This intermediate component facilitates proper tissue adhesion and positioning without directly contacting the tissue in a way that would cause leakage, solving the adherence problem while preserving throughput

Inventive Principle:
Principle #24Intermediary (Mediator)

3Productivity

If multiple tissue segments are analyzed simultaneously, then throughput increases, but device complexity and assembly difficulty increase

Engineering Contradiction:
Improvenumber of segments analyzed simultaneouslyVSAvoidcomplexity of multiwell format assembly
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The vial assembly design provides universal functionality that can be scaled from single vial to multiwell formats. The standardized crimp cap and inert material ring configuration works identically whether one or multiple vials are used, allowing easy expansion to simultaneous analysis of multiple segments without proportionally increasing assembly complexity

Inventive Principle:
Principle #6Universality (Multi-functionality)

4Reliability

If thick epithelial tissues are mounted in traditional vertical chambers, then tissue can be held, but leakage occurs and mounting is difficult

Engineering Contradiction:
Improvesealing effectivenessVSAvoidease of mounting thick tissues
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The invention employs a disposable vial assembly with a crimp cap and inert material ring that is optimized for single-use mounting of thick epithelial tissues. This disposable design ensures consistent sealing effectiveness without the need for complex reusable components, making mounting of thick tissues both reliable and easy

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)
