Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional sampling equipment is released by shipboard geological winches and allowed to go down under gravity, then the equipment can reach deep sea environments, but the sampling process cannot be monitored in real-time and data collection is discontinuous

Engineering Contradiction:
Improvedata continuityVSAvoidreal-time monitoring capability
Core Design Contradiction:
ReliabilityVSExtent of automation

Solution Approach 1:

The patent replaces conventional mechanical gravity-based sampling with an automated water flow-driven system. Water flows through the trap pipes carrying sediments, and the system automatically collects and monitors sediments in real-time, eliminating the need for manual deployment and recovery operations while ensuring continuous data collection.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The trap pipes are designed to continuously capture sediments as water flows through them, rather than collecting discrete samples. The system maintains continuous operation with water constantly flowing through the trap pipes, ensuring uninterrupted sediment collection and real-time monitoring capability throughout the deployment period.

Inventive Principle:
Principle #20Continuity of useful action

2Productivity

If abyssal vehicles are used for bottom sampling, then sampling efficiency is improved and sampling areas can be selected, but scientists cannot make real-time selection at sampling points or visually obtain samples

Engineering Contradiction:
Improvesampling efficiencyVSAvoidreal-time sampling selection capability
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The patent introduces transparent observation windows as intermediaries between the sampling system and scientists. These windows allow real-time visual observation of sediment accumulation in the trap pipes, enabling scientists to make informed real-time decisions about sampling points and timing while maintaining high sampling efficiency through the automated water flow system.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Measurement precision

If filter screens are installed in water flow pipes to intercept sediments, then sediment collection accuracy is improved, but the device complexity increases

Engineering Contradiction:
Improvesediment collection accuracyVSAvoidstructure complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent employs filter screens with specific pore sizes installed within the water flow pipes to intercept and retain sediments while allowing water to pass through. This porous material approach achieves accurate sediment collection by physically filtering particles from the water flow, while the modular integration within existing pipe structures minimizes overall system complexity.

Inventive Principle:
Principle #31Porous materials

AI summary

The present invention relates to a 3D time series vector sediment trap comprising a base disposed with trap pipes (2) which consist of water flow pipes (21) and sedimentation pipes (22), where the water flow pipes (21) have a horizontal water inlet (210) at the front end, a vertical downward water outlet (211) at the back end and a filter screen (212) inside it which tilts towards the water inlet (210). The filter screen (210) is internally tangential to the water flow pipe (21); and the sedimentation pipes (22), vertically fixed underneath the water flow pipes, have an open top end and a closed bottom end, where the open end communicates with the water flow pipe (21) and directly faces the filter screen (212) so that materials larger than the screen pore diameter are intercepted by the filter screen (212) in the water flow pipe and collected in the sedimentation pipe (22). The trap according to the present invention can dynamically collect sedimenting particulate materials in the seawater as the ocean current flows and accurately monitors environmental changes at the sea bottom.
