Solution Overview

Problem

Existing slide imaging apparatuses face challenges with accommodating multiple slides, requiring a wider footprint and manual handling of copy holders, which can lead to loose slides and potential damage during mounting.

Innovation Solution

A slide imaging apparatus with a copy holder moving system that includes a movable stage and indexing mechanisms, allowing slides to be held in multiple imaging locations, enabling efficient image formation without increasing the apparatus' width, and featuring automated loading and unloading processes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If the apparatus accommodates multiple slides using a wider footprint design, then more slides can be held simultaneously, but the apparatus size increases

Engineering Contradiction:
Improvenumber of slides heldVSAvoidapparatus width
Core Design Contradiction:
Quantity of substanceVSArea of stationary object

Solution Approach 1:

The patent transitions from a wide horizontal layout to a vertical stacked configuration. Multiple slide holders are arranged vertically above the imaging system, allowing multiple slides to be accommodated without increasing the apparatus width. The movable stage moves slides vertically into and out of the imaging position, resolving the contradiction between holding multiple slides and maintaining a compact footprint.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Device complexity

If manual handling of copy holders is used, then the system is simpler, but slides may become loose and get damaged during mounting

Engineering Contradiction:
Improvesystem simplicityVSAvoidslide security during mounting
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The system employs an automated movable stage that self-adjusts to position slides accurately in the imaging location. The stage includes positioning mechanisms that automatically align and secure slides without manual intervention, eliminating the risk of loose slides and damage while maintaining operational simplicity through automation.

Inventive Principle:
Principle #25Self-service

3Area of stationary object

If multiple slides are held in the same imaging location, then the apparatus remains compact, but slides cannot be efficiently processed in parallel

Engineering Contradiction:
Improveapparatus widthVSAvoidimage formation efficiency
Core Design Contradiction:
Area of stationary objectVSProductivity

Solution Approach 1:

Multiple slides are pre-loaded onto the movable stage in a vertical stack before the imaging process begins. The stage is configured to sequentially present each slide to the imaging system in turn, allowing efficient processing of multiple slides without requiring parallel imaging capabilities. This preliminary arrangement enables compact design while maintaining productivity through systematic sequential processing.

Inventive Principle:
Principle #10Preliminary action

AI summary

A slide imaging apparatus that includes a copy holder moving system and an imaging system. The copy holder moving system includes a movable stage configured to move along first and second slide movement axes relative to the imaging system, wherein the imaging system is configured to form an image of a sample mounted on a slide located in the/each imaging location on the movable stage during an image forming process that includes the movable stage moving relative to the imaging system along the first and second slide movement axes. The copy holder moving system also includes a copy holder configured to be mounted to the movable stage, wherein the copy holder is configured to be mounted to the movable stage in each of a plurality of indexing positions.
