Support Structure With Tapered Peripheral Space For Sealing

Solution Overview

Problem

Existing methods for integrating structures in supports with through cavities expose sealing materials to fluids, leading to interactions that perturb chemical and biological analyses, and reducing the radial extension of the sealing material is limited by its high viscosity, causing unwanted shrinkage and topology changes.

Innovation Solution

A method involving a support with through cavities where the peripheral space's radial extension length decreases from the rear face to the front face, using a combination of first and second sealing materials with varying radial extension lengths, and forming layers on the through wall and contour to minimize exposure and interaction with fluids.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If the radial extension length of the peripheral space is reduced to minimize sealing material exposure to fluids, then the interaction between sealing material and fluid is reduced, but the sealing material cannot flow properly into the peripheral space due to its high viscosity

Engineering Contradiction:

Improveinteraction between sealing material and fluidVSAvoidflow of sealing material into peripheral space

Core Design Contradiction:

Object-affected harmful factorsVSEase of manufacture

Solution Approach 1:

The peripheral space is designed with varying radial extension length along the depth of the support. The radial extension length is greater at the rear face (first section) to facilitate sealing material flow, and smaller at the front face (second section) to minimize fluid interaction. This local variation in geometry allows different regions of the peripheral space to serve different functions.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The peripheral space is divided into two distinct sections based on their functional requirements: a first section with larger radial extension length for sealing material accommodation and flow, and a second section with smaller radial extension length for minimizing fluid interaction. This segmentation allows each section to be optimized for its specific purpose.

Inventive Principle:

Principle #1Segmentation

2Manufacturing precision

If the radial extension length of the peripheral space is reduced to limit shrinkage during hardening, then the topology of the sealing material surface is improved, but the sealing material cannot adequately fill the peripheral space

AI summary

The invention relates to a method for integrating structures in a support, which comprises the steps:a) supplying a support comprising a front face and a rear face, and through cavities each delimited by a wall designated through wall;b) inserting into each of the through cavities a structure, provided with a first face and a second face connected by a contour, the first face and the front face being coplanar, the through cavities and/or the structures being laid out to leave a peripheral space;c) filling the peripheral space with a sealing material so as to maintain the structures to the support;The peripheral space has a radial extension length which decreases from the rear face to the front face.
