Solution Overview

Problem

Existing systems for examining and manipulating samples lack precision and repeatability when exchanging samples between devices or systems, leading to inefficiencies in measurement chains.

Innovation Solution

A holding system comprising a holding module and a carrier module that provides a reproducible reference position, allowing the carrier module to be locked in a consistent position relative to the holding module, enabling precise and repeatable sample positioning across different devices or systems.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If samples are exchanged between devices or systems, then sample handling flexibility is improved, but positioning precision and repeatability deteriorate

Engineering Contradiction:
Improvesample handling flexibilityVSAvoidpositioning precision
Core Design Contradiction:
Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The system is divided into a holding module (fixed to device) and a carrier module (removable with sample), allowing flexible exchange of carrier modules while maintaining precise positioning through the reference position mechanism on the holding module

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A reference position mechanism acts as an intermediary between the holding module and carrier module, providing a stable reference point that enables precise and repeatable positioning even when carrier modules are exchanged between different devices

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If samples are exchanged between devices or systems, then sample handling flexibility is improved, but positioning repeatability deteriorates

Engineering Contradiction:
Improvesample handling flexibilityVSAvoidpositioning repeatability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The reference position mechanism provides a universal reference point that works across multiple devices and carrier modules, ensuring that the same reference position can be reproduced regardless of which carrier module is installed or which device is used

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

3Device complexity

If manual positioning methods are used, then device complexity is reduced, but productivity deteriorates

Engineering Contradiction:
Improvepositioning system complexityVSAvoidsample handling efficiency
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The reference position is pre-established on the holding module before carrier module installation, allowing automatic positioning to be performed quickly after module exchange without complex real-time adjustment mechanisms

Inventive Principle:
Principle #10Preliminary action
