Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing slides for microscopy or analytical technology face issues with data carriers being easily lost or damaged due to adhesive failure, which impairs functionality and data integrity.

Innovation Solution

Embedding an information medium, such as an electronic component, within the slide's recess using a casting compound to create a robust and permanent connection, ensuring the data carrier is fully enclosed and protected, maintaining the slide's geometry and ease of handling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a data carrier is attached to the slide surface using adhesive, then the slide can be identified and tracked, but the adhesive may fail and cause the data carrier to be lost or damaged

Engineering Contradiction:

Improvedata carrier retentionVSAvoidadhesive failure

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The data carrier is embedded within a recess in the slide, nesting one structure within another. The recess is formed in the slide body, and the data carrier is placed inside this recess and sealed with casting compound, creating a nested configuration that prevents loss while maintaining identification functionality

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The casting compound acts as an intermediary material between the data carrier and the slide. This intermediary substance provides mechanical bonding and environmental sealing, transferring the retention function from the unreliable adhesive to the more robust casting compound while protecting the data carrier from external factors

Inventive Principle:

Principle #24Intermediary (Mediator)

2Strength

If the information medium is embedded in the slide, then the connection becomes more robust and permanent, but the slide geometry is altered

Engineering Contradiction:

Improveconnection strengthVSAvoidslide geometry

Core Design Contradiction:

StrengthVSShape

Solution Approach 1:

The recess is created only in the peripheral area of the slide, not in the central specimen area. This local modification allows strong embedding of the data carrier while preserving the overall slide geometry and functionality for microscopy. The recess is positioned at the edge where it does not interfere with the specimen placement or observation area

Inventive Principle:

Principle #3Local quality

3Ease of operation

If the recess penetrates the slide completely, then the information medium can be easily accessed, but the information medium may fall through during fastening

Engineering Contradiction:

Improveinformation medium accessibilityVSAvoidinformation medium retention

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The recess is designed to be partial rather than complete - it extends through most of the slide thickness but stops before the back surface. This partial penetration provides sufficient access for inserting and fastening the data carrier while maintaining a retaining floor that prevents the carrier from falling through during the fastening process

Inventive Principle:

Principle #16Partial or excessive action
