Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional tank wave-current generation systems face issues with current stabilization due to vortex-shaped current entry, which disrupts wave generation and requires excessively long tanks, violating the principle of linear current generation.
Innovation Solution
A tank wave-current generation system with a rear-mounted outlet, featuring a rectifying device with a chamber and grid that dissipates energy and stabilizes the current before entry, combined with intelligent control of water inlet and wave generation speed by a computer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the water inlet pipe is directly mounted in front of the wave pushing plate, then the current can enter the tank directly, but the current enters in a vortex shape requiring a long transition section to be stabilized
Solution Approach 1:
The water inlet pipe is mounted at the rear end of the tank, allowing current to be preliminarily generated and stabilized in a separate water collection area before entering the main tank. This preliminary action prevents vortex formation at the entry point and eliminates the need for a long transition section within the main tank.
2Ease of operation
If the water inlet pipe is directly mounted in front of the wave pushing plate, then the current entry is simple, but the vortex-shaped current destroys the wave shape when wave-current interaction is needed
Solution Approach 1:
The system preliminarily generates and stabilizes current in a water collection area before the current enters the main tank. This preliminary stabilization ensures that when wave-current interaction is needed, the current is already stable and will not destroy the wave shape.
Solution Approach 2:
The water collection area acts as an intermediary between the water inlet and the main tank. It serves as a buffer zone where current is stabilized before entering the main tank, preventing direct vortex entry that would disrupt wave formation.
3Stability of the object's composition
If the tank is made long enough to include a transition section for current stabilization, then current can be stabilized, but the tank cannot be used in the transition section violating the infinite length use principle
Solution Approach 1:
Current stabilization is performed preliminarily in a separate water collection area before current enters the main tank. This separates the stabilization function from the main tank, allowing the main tank to be used for its full length without dedicating space to transition sections.
Solution Approach 2:
The system is segmented into a water collection area for current stabilization and a main tank for testing. This segmentation allows each component to perform its specific function independently, with the main tank maintaining its full usability for experiments.
4Stability of the object's composition
If a rectifying device with energy dissipation is added to stabilize current, then current stability is improved, but the device complexity increases
Solution Approach 1:
The rectifying device is placed in the water collection area to preliminarily stabilize current before it enters the main tank. This location choice allows the rectifying device to perform its function without interfering with the main tank's test operations, making the added complexity acceptable.
