Solution Overview

Problem

In pathological diagnosis using microscope systems, accurate reproduction of observation positions and image capturing positions is challenging due to rotational shifts between the imaging unit and the microscope, making precise positioning difficult for morphological and functional diagnoses.

Innovation Solution

An adapter with a first connection member for the microscope, a second connection member for the imaging unit, a rotation member to align optical axes, a control member for fixing positions, and a driving member for precise positional adjustments, allowing accurate rotation and positioning between the microscope and imaging unit.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If the stage and observation optical system are rotated in cooperation to correct rotational shift, then the rotational alignment between slide position and stored position can be improved, but the device complexity increases due to coordinated rotation mechanisms

Engineering Contradiction:
Improverotational alignment accuracyVSAvoidcoordinated rotation mechanism
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent introduces an adapter as an intermediary component between the imaging unit and microscope. This adapter includes a rotation member with a control member that can rotate the imaging unit independently around the optical axis, serving as a mediator to correct rotational shifts without requiring complex coordinated rotation of the entire microscope system

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The rotation function is segmented and isolated to the adapter component rather than requiring coordinated rotation of the stage and optical system. The control member on the rotation member allows independent rotation of the imaging unit, dividing the correction function from the main microscope system

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If a rotation member with control member is added to the adapter, then the ease of operation for rotational adjustment is improved, but the device complexity increases

Engineering Contradiction:
Improverotational adjustmentVSAvoidadapter structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The control member is designed to be operated directly by the user to rotate the rotation member and adjust the imaging unit's orientation. This self-service mechanism allows intuitive rotational adjustment without requiring complex external control systems or coordinated operations of multiple components

Inventive Principle:
Principle #25Self-service

AI summary

An adapter which controls rotation of a microscope on which a slide is placed and an imaging unit and which easily performs correction of a rotation shift is provided. The adapter includes a first connection member connected to a microscope, a second connection member connected to an imaging unit, a rotation member arranged between the first and second connection members and configured to rotate the second connection member relative to the first connection member using optical axes of the microscope and the imaging unit at a center, a control member configured to be fixed on one of the first and second connection members and control the rotation of the connection member, and a driving member configured to be engaged with the first connection member or the second connection member and change a position of the second connection member relative to the first connection member around the optical axes.
