Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid injection systems for large fish tanks, such as those used in land-based fish farming, face challenges in efficiently providing a constant supply of fresh water while minimizing space occupation and maintaining optimal hydraulic conditions, which are crucial for fish health and production efficiency.
Innovation Solution
An injection element comprising an outer and inner pipe, where the inner pipe is movable relative to the outer pipe, allowing flexible injection angles and positions, enabling fluid injection without occupying significant tank space, and facilitating easy cleaning and adjustment of fluid flow patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a traditional inlet pipe is placed vertically inside the tank from rim to bottom, then fluid can be supplied to the tank, but the pipe occupies significant tank space and creates hydraulic obstacles
Solution Approach 1:
The inner pipe is nested inside the outer pipe, allowing the injection element to be retractable. When retracted, the inner pipe fits within the outer pipe's diameter, minimizing space occupation. When extended, the inner pipe can reach the tank bottom for effective fluid injection, thus resolving the contradiction between space occupation and fluid supply reliability
Solution Approach 2:
The injection element is made dynamically adjustable through the movable inner pipe that can be extended or retracted. This dynamic configuration allows the system to adapt between two states: retracted state for minimal space occupation and extended state for effective fluid injection, thereby maintaining reliability while reducing space usage
2Object-affected harmful factors
If the inlet pipe creates a circular flow pattern, then fish health is improved, but the pipe structure creates turbulence and hydraulic obstacles
Solution Approach 1:
The injection element is segmented into outer pipe and inner pipe components. The outer pipe remains stationary while the inner pipe can be moved independently to optimize injection positioning. This segmentation allows the system to create effective circular flow patterns without the stationary pipe structure creating excessive turbulence, thus improving fish production efficiency while reducing harmful turbulence
Solution Approach 2:
The inner pipe is extracted from the outer pipe to a controlled extent, allowing fluid injection to occur from a specific position without the entire pipe structure being inside the tank. This extraction minimizes the physical presence of the pipe structure in the tank, reducing hydraulic obstacles and turbulence while still enabling effective fluid injection for fish production
3Adaptability or versatility
If the injection element is fixed in position, then installation is simple, but adjustment of injection angles and positions is limited
Solution Approach 1:
The inner pipe is designed to be movable within the outer pipe, transforming the fixed structure into a dynamic one. This allows the injection angle and position to be adjusted by moving the inner pipe to different extensions, providing adaptability without requiring a completely complex reconfigurable structure
Solution Approach 2:
The nested structure of inner pipe within outer pipe provides a compact and relatively simple mechanism for achieving movement and adjustment. The nesting allows the movable component to be housed within the stationary component, maintaining structural simplicity while enabling injection angle and position adjustment through the movable inner pipe
