Solution Overview

Problem

Existing microplate processing devices require significant space and have complex manipulators that restrict accessibility due to their multi-directional movement and limited access to microplates, making them inefficient for handling microplates.

Innovation Solution

A microplate processing device with a carriage that moves horizontally and a lift that moves vertically, featuring a through opening with recesses and a second receptacle with arms and stops to facilitate easy access and positioning of microplates, allowing for compact design and improved accessibility.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a manipulator is used to handle microplates, then microplates can be transferred between carriages and processing areas, but the device requires significant space and has complex multi-directional movement mechanisms that restrict accessibility

Engineering Contradiction:
ImproveAccessibility to microplateVSAvoidManipulator structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent extracts the complex manipulator mechanism from the system and replaces it with a simplified configuration where the carriage itself has integrated microplate handling capabilities through the through-opening and lift mechanism. This removes the need for separate complex manipulators while maintaining microplate transfer functionality.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

Instead of using a manipulator to reach down to the carriage level, the invention inverts the approach by having the carriage structure itself provide access to microplates through the through-opening, allowing vertical access from above without requiring horizontal manipulator movement.

Inventive Principle:
Principle #13The other way round (Inversion)

2Area of stationary object

If a manipulator with multi-directional movement is used, then microplates can be accessed from different positions, but the accessibility is still limited and the device requires more space

Engineering Contradiction:
ImproveDevice footprintVSAvoidMicroplate accessibility
Core Design Contradiction:
Area of stationary objectVSEase of operation

Solution Approach 1:

The patent transitions from horizontal manipulator movement to vertical access through the through-opening. The lift mechanism moves microplates vertically between the carriage and processing area, utilizing the vertical dimension to achieve accessibility without requiring additional horizontal space.

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

3Area of stationary object

If a compact design is implemented, then space is saved, but accessibility to microplates may be restricted

Engineering Contradiction:
ImproveDevice footprintVSAvoidGripper access to microplate
Core Design Contradiction:
Area of stationary objectVSEase of operation

Solution Approach 1:

The carriage structure is segmented with a through-opening that creates distinct access zones. The lift mechanism is positioned to provide clear access paths, allowing grippers to approach microplates from multiple angles without requiring large overall device dimensions.

Inventive Principle:
Principle #1Segmentation
