Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If samples are stored in a controlled environment with low temperature, then sample preservation is improved, but access to samples becomes more difficult and mechanical complexity increases

Engineering Contradiction:
Improvesample preservationVSAvoidmechanical complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The storage system is divided into multiple independent modules (source module, destination module, bridge module) that can operate autonomously. Each module handles specific functions, allowing the system to maintain complex temperature control while simplifying individual component operations and reducing overall mechanical complexity through modular design.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The bridge module serves as an intermediary between the source and destination modules, facilitating sample transfer without requiring direct access to the cold storage environment. This intermediary structure enables mechanical operations to be performed at higher temperatures while maintaining sample preservation in the controlled low-temperature environment.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Quantity of substance

If multiple samples are stored in a compact array, then storage capacity is improved, but retrieval speed and access flexibility deteriorate

Engineering Contradiction:
Improvestorage capacityVSAvoidretrieval speed
Core Design Contradiction:
Quantity of substanceVSSpeed

Solution Approach 1:

The sample array is segmented into multiple racks that can be independently accessed and retrieved. This segmentation allows the system to maintain high storage capacity through compact arrays while improving retrieval speed by enabling selective access to specific racks without moving entire arrays, thus resolving the contradiction between storage density and retrieval efficiency.

Inventive Principle:
Principle #1Segmentation

3Productivity

If robotic systems are used for sample handling, then automation and retrieval speed are improved, but reliability deteriorates due to temperature sensitivity

Engineering Contradiction:
Improveretrieval speedVSAvoidsystem reliability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The bridge module acts as a thermal intermediary, allowing robotic systems to perform sample handling operations at higher temperatures where they are more reliable, while still enabling access to samples stored in the controlled low-temperature environment. This intermediary structure decouples the temperature sensitivity issue from the automation functionality.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The robotic handling system is extracted from the cold storage environment and placed in a separate, temperature-friendly zone. This extraction allows the robotic components to operate reliably at higher temperatures while still performing the function of sample retrieval and transfer, thus maintaining both automation and reliability.

Inventive Principle:
Principle #2Taking out (Extraction)

4Ease of operation

If the storage system is designed for flexible access, then ease of operation is improved, but sample exposure to environmental changes increases

Engineering Contradiction:
Improveaccess flexibilityVSAvoidsample exposure
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The storage system is segmented into multiple racks and modules that can be independently accessed. This segmentation enables flexible access to specific samples or groups of samples without requiring access to the entire storage array, thereby maintaining ease of operation while minimizing the total surface area exposed to environmental changes and reducing sample exposure risk.

Inventive Principle:
Principle #1Segmentation

AI summary

An automated storage system for storing large quantities of samples in trays includes a storage compartment, a tray shuttle compartment abutting the storage compartment on one side and a plurality of independent modules on the other side. The modules perform processing of samples that are retrieved from the storage compartment by a tray shuttle, including extraction of selected samples from retrieved source trays and transfer of the selected samples into a separate, destination tray that can be further processed or removed from the system for use. The independent operation of the modules permits handling and processing to be performed simultaneously by different modules while the tray shuttle accesses additional samples within the storage compartment.; In one embodiment, a vertical carousel is used to vertically align a desired tray with the tray shuttle, while the tray shuttle operates within a horizontal plane.
