Solution Overview

Problem

Existing sample producing apparatuses require improvements to enhance working efficiency in producing observation samples, particularly in terms of reducing the moving distance or range required for operators to produce samples efficiently.

Innovation Solution

A sample producing apparatus is designed with a housing containing a holding portion for the optically transparent plate, a moving unit to transport the plate to an imparting region, and a control unit that directs the moving unit to move from a supply position to an imparting position, optimizing the workflow for efficient sample production.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the imparting region is positioned at a corner portion close to both front wall portion and one side wall portion of the housing, then the working efficiency is improved by reducing the moving distance for operators, but the device complexity increases due to the need for precise positioning and control mechanisms

Engineering Contradiction:
Improveworking efficiencyVSAvoiddevice complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The imparting region is positioned at a corner portion of the housing, utilizing the three-dimensional space efficiently. This corner positioning allows operators to access the imparting region from multiple directions (front and side), effectively reducing the moving distance required during sample production while maintaining a compact overall device structure.

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

Solution Approach 2:

The holding portion is designed to automatically move the plate to the pre-determined corner imparting region, eliminating the need for operators to manually transport plates across the entire housing. This preliminary automated positioning action reduces both moving distance and operational complexity.

Inventive Principle:
Principle #10Preliminary action

2Productivity

If the holding portion moves automatically from supply position to imparting position under control unit control, then the working efficiency is improved, but the device complexity increases due to additional moving and control mechanisms

Engineering Contradiction:
Improveworking efficiencyVSAvoiddevice complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The moving unit serves multiple functions: it transports the plate from the supply position to the imparting position, positions the plate accurately at the corner region, and facilitates efficient workflow. This multi-functionality reduces the need for separate dedicated mechanisms for each operation, thereby improving working efficiency while limiting the increase in overall device complexity.

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

Solution Approach 2:

The control unit automatically manages the movement of the holding portion and plate positioning without requiring continuous manual intervention. The system performs self-service operations by autonomously navigating the plate to the optimal imparting position, improving efficiency while the automated control reduces the complexity of manual operation procedures.

Inventive Principle:
Principle #25Self-service
