Solution Overview

Problem

Existing biological sampling systems face challenges in obtaining complete deep-sea creature community samples, precisely controlling sampling water depth, and ensuring the survival rate and integrity of captured samples. Additionally, operators cannot directly observe the quantity of creatures or the status of the trawl net during use, making it inconvenient and potentially damaging.

Innovation Solution

A visualized biological trawl net system based on a submersible, which includes a fixation frame, collection net, filtering mechanism, fish observation camera, and central control system. This system allows for real-time observation and monitoring of marine creatures, enabling more precise sampling and reducing damage to the trawl net.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If traditional bottom trawl nets are used for deep-sea sampling, then sampling capability is provided, but operators cannot observe creatures or trawl net status in real-time

Engineering Contradiction:

ImproveReal-time observation capabilityVSAvoidSystem structure

Core Design Contradiction:

Loss of informationVSDevice complexity

Solution Approach 1:

The patent combines the trawl net system with a submersible vehicle and integrated detection equipment into a single unified platform. The submersible integrates the collection net, filtering mechanism, fish observation camera, and central control system into one cohesive structure, allowing simultaneous sampling and real-time monitoring without requiring separate systems.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent replaces manual observation and mechanical sampling methods with electronic imaging systems (fish observation cameras) and automated control systems. The camera system captures visual data of creatures and net status, which is then transmitted to operators, substituting direct mechanical observation with electronic information transmission.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If preset sampling conditions are used, then sampling operation is simplified, but adaptation to complex underwater environment is limited

Engineering Contradiction:

ImproveEnvironmental adaptation capabilityVSAvoidOperation complexity

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent implements dynamic sampling capabilities where the collection net can be deployed and retrieved at varying depths and locations based on real-time observations. The system allows operators to adjust sampling parameters dynamically during operation, transitioning from static preset conditions to adaptive dynamic control based on actual underwater conditions and creature distribution.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system incorporates real-time feedback through fish observation cameras that transmit visual information about creature presence and net status back to the operators. This feedback loop enables operators to make informed decisions about sampling depth, location, and duration, allowing the system to adapt to complex underwater environments while maintaining operational simplicity through guided control.

Inventive Principle:

Principle #23Feedback

3Productivity

If mechanical sampling methods are used, then sampling efficiency is improved, but survival rate and integrity of captured creatures deteriorate

Engineering Contradiction:

ImproveSampling efficiencyVSAvoidCreature survival rate

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent replaces harsh mechanical sampling methods with a gentler integrated system that uses water flow and filtering mechanisms instead of aggressive mechanical extraction. The collection net design and filtering mechanism minimize mechanical stress on captured creatures, maintaining sampling efficiency while significantly improving creature survival rates and sample integrity.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
