Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If traditional fire detection systems are installed in automated storage and retrieval systems, then fire detection capability is provided, but the systems fail to provide reliable location information for firefighting crews

Engineering Contradiction:
Improvefire location precisionVSAvoidlocation information
Core Design Contradiction:
Measurement precisionVSLoss of information

Solution Approach 1:

The patent introduces remotely operated vehicles as intermediary carriers that transport fire detection devices through the automated storage and retrieval system. These vehicles act as mobile platforms that can reach locations where fixed detection systems cannot, while the master control system coordinates their movement and processes their detection data to generate actionable location information for firefighting crews.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent transforms the fire detection system from a static, fixed installation to a dynamic, mobile configuration. The remotely operated vehicles can be dispatched to specific locations based on fire alarms or proactively patrol different areas, allowing the detection capability to adapt to varying operational needs and provide real-time location data that updates as vehicles move through the system.

Inventive Principle:
Principle #15Dynamics

2Reliability

If remotely operated vehicles with fire detection devices are deployed, then accurate heat map and location information is provided, but the system complexity increases

Engineering Contradiction:
Improvefire detection reliabilityVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The remotely operated vehicles serve multiple functions: they perform normal container handling operations while simultaneously carrying fire detection devices. This multi-functionality allows the system to leverage existing infrastructure and vehicles for fire detection purposes, reducing the need for dedicated detection equipment and simplifying the overall system architecture despite the added capability.

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

Solution Approach 2:

The master control system implements feedback mechanisms by receiving detection data from remotely operated vehicles, processing this information to generate heat maps and location data, and using this feedback to dispatch additional vehicles or alert firefighting crews. This closed-loop feedback system ensures reliable fire detection while maintaining manageable complexity through automated decision-making algorithms.

Inventive Principle:
Principle #23Feedback

3Measurement precision

If multiple remotely operated vehicles are used for fire detection, then verification capability is enhanced, but the quantity of vehicles and system resources increase

Engineering Contradiction:
Improvefire verification accuracyVSAvoidnumber of vehicles
Core Design Contradiction:
Measurement precisionVSQuantity of substance

Solution Approach 1:

The system implements verification by dispatching additional remotely operated vehicles only when initial detection data requires confirmation, rather than continuously deploying multiple vehicles for all detection scenarios. This partial action approach provides sufficient verification capability to eliminate false alarms while avoiding the unnecessary deployment of excessive vehicle resources during routine operations.

Inventive Principle:
Principle #16Partial or excessive action
