Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If dedicated add-on buffers are provided within each laboratory station, then samples waiting for conditional further processing can be stored, but the device complexity and resource allocation increase

Engineering Contradiction:
Improvesample processing completenessVSAvoidbuffer configuration complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The invention extracts the buffer function from individual laboratory stations and consolidates it into a centralized buffer area on the transport plane. This eliminates the need for each station to have its own dedicated add-on buffer, thereby reducing device complexity while maintaining the capability to store samples waiting for conditional further processing.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The centralized buffer area serves as a universal storage resource for the entire laboratory automation system, replacing multiple station-specific buffers. This multi-functional buffer can serve any laboratory station that needs to store samples for conditional further processing, reducing overall system complexity while maintaining reliability.

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

2Reliability

If fixed buffer sizes are allocated within laboratory stations, then sample storage is guaranteed, but adaptability to varying operational conditions deteriorates

Engineering Contradiction:
Improvesample storage availabilityVSAvoidoperational condition adaptability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The invention implements dynamic buffer allocation where the buffer area size and characteristics can be adjusted based on current operational conditions. The control unit monitors system state and dynamically modifies buffer parameters, allowing the system to adapt to varying traffic loads and operational requirements while maintaining reliable sample storage capability.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes buffer parameters (size, location, capacity) dynamically based on operational conditions such as traffic load, processing speed, and sample accumulation rates. This allows the buffer to maintain reliability across different operational scenarios while adapting to varying demands.

Inventive Principle:
Principle #35Parameter changes

3Productivity

If large buffer areas are provided within each station, then sample throughput is maintained during peak conditions, but resource allocation efficiency decreases

Engineering Contradiction:
Improvesample throughputVSAvoidbuffer resource utilization
Core Design Contradiction:
ProductivityVSQuantity of substance

Solution Approach 1:

The invention merges individual station buffers into a single centralized buffer area on the transport plane. This consolidation allows efficient resource allocation where the buffer capacity is shared across all stations, maintaining high sample throughput during peak conditions while improving overall resource utilization efficiency.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The buffer functionality is moved from the vertical dimension (within-station storage) to the horizontal dimension (transport plane). This dimensional shift allows the buffer to be integrated into the existing transport infrastructure, improving resource utilization while maintaining throughput capability.

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