Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current research methods for fish surveys in tidal channels are limited to low tide collections, lacking detailed investigation and quantitative evaluation of substances entering during high tide, and there is a need for comprehensive sampling and assessment of biological and material transport effects of both high and low tides.
Innovation Solution
A floating platform with a survey sampling net and connection method, using a galvanized tube frame and circular bearings, allows for sampling at both high and low tides, with nets rotating, retracting, and dropping via cables, and includes a quantitative assessment method to measure tidal flow and collect aquatic organisms and nutrients.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If fixed nets are set in tidal channels and sampling is conducted only at low tide, then the investigation method is simple and easy to operate, but the survey coverage is limited and cannot capture high tide biological and material transport
Solution Approach 1:
The patent employs a movable floating platform that can dynamically adjust its position and sampling net deployment based on tidal conditions. The platform transitions from a static fixed-net approach to a dynamic system that actively responds to high and low tide cycles, enabling sampling operations during both tidal phases and comprehensively capturing biological and material transport throughout the tidal cycle.
Solution Approach 2:
The floating platform is designed as a multi-functional system that performs multiple sampling operations during both high tide and low tide. It can simultaneously conduct biological sampling, material transport assessment, and ecological function evaluation, replacing the single-function fixed net approach that only operated at low tide.
2Device complexity
If fixed nets are used for fish survey, then the device structure is simple, but the quantitative assessment of biological and material transport effects is insufficient
Solution Approach 1:
The patent segments the sampling system into multiple functional components: the floating platform, deployable sampling nets, flow meters for measuring water discharge, and separate collection containers for different samples. This segmentation allows each component to perform its specific function optimally while collectively providing comprehensive quantitative assessment capabilities that exceed simple fixed net systems.
Solution Approach 2:
The floating platform serves as an intermediary carrier that integrates multiple measurement and sampling tools. It mediates between the tidal environment and the sampling instruments, providing a stable base for deploying nets, housing flow meters, and collecting samples during both high and low tide conditions, thereby enabling precise quantitative assessment.
3Ease of operation
If sampling is conducted only at low tide, then the investigation method is simple, but the ecological function assessment of tidal channels is incomplete
Solution Approach 1:
The floating platform enables continuous sampling operations throughout the entire tidal cycle, including both high tide and low tide phases. By continuously deploying and retrieving nets during tidal fluctuations, the system captures uninterrupted data on biological transport, nutrient flow, and ecological processes, eliminating the information loss that occurs with intermittent low-tide-only sampling.
