Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aquaponics systems and traditional water filtering tanks for aquatic animals face challenges such as inadequate water circulation, incomplete water treatment, leakage issues, noise from siphoning, and inefficient maintenance due to clogged filtering materials and the need for oxygen pumps, leading to reduced performance and increased energy consumption.
Innovation Solution
The development of tide water filtering tanks with high circulation rates, featuring a large siphon pipe, multiple-layered filtering baskets, and a U-turn snock pipe to enhance water and air circulation, reduce noise, and allow for stable installation without a base, eliminating the need for oxygen pumps by promoting continuous air and water circulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by stationary object
If low-water circulation is used in aquaponics systems, then energy consumption is reduced and planting is supported, but water treatment performance is insufficient for aquaculture purposes
Solution Approach 1:
The system dynamically adjusts water circulation between two modes: low circulation (48 rounds/day) for energy-saving during planting periods, and high circulation (120-150 rounds/day) for effective water treatment during aquaculture periods. This dynamic operation resolves the contradiction by allowing the system to adapt its performance level to current needs.
Solution Approach 2:
The bell siphon mechanism creates periodic water circulation cycles, automatically alternating between filling and emptying phases. This periodic action enables the system to achieve both low energy consumption during planting and adequate water treatment during aquaculture without continuous high-energy operation.
2Ease of operation
If water is released frequently from planting trays, then plant roots contact oxygen preventing root rot, but filtering materials have less contact time with water reducing treatment effectiveness
Solution Approach 1:
The system segments the water treatment function into two locations: planting trays for oxygen contact and a separate filtering tank for comprehensive water treatment. This segmentation allows water to be released from trays for root aeration while filtering materials in the separate tank maintain continuous contact with water for effective treatment.
Solution Approach 2:
The filtering tank acts as an intermediary between the planting trays and the water source. Water is transferred from trays to the filtering tank where filtering materials provide extended contact time for treatment, then treated water is returned to the system, resolving the conflict between oxygen contact and treatment effectiveness.
3Ease of manufacture
If outlet stand pipe uses external and internal threading joints, then attachment to tray is achieved, but leakage occurs in the long term
Solution Approach 1:
The problematic threading joints are extracted from the system and replaced with a simplified socket insertion connection. This removes the source of leakage while maintaining the attachment function, resolving the contradiction between ease of manufacture and long-term reliability.
4Ease of operation
If outlet pipe direction is outward from bottom of tray, then water discharge is achieved, but tray base must be lifted causing instability and aesthetic issues
Solution Approach 1:
Instead of directing the outlet pipe outward from the bottom requiring tray elevation, the system inverts the approach by using a bottom-discharge configuration where the outlet stand pipe extends downward. This allows the tray to remain at ground level, maintaining stability and aesthetics while achieving effective water discharge through the bell siphon mechanism.
5Productivity
If bell siphon stops due to air mass, then water circulation cycle completes, but loud noise is generated disturbing residents
Solution Approach 1:
The noisy air mass release mechanism is extracted from the residential area by positioning the outlet pipe away from living spaces. Additionally, a water seal is introduced to suppress air noise, separating the harmful noise generation from the useful water circulation function.
Solution Approach 2:
A water seal acts as an intermediary between the bell siphon and the atmosphere, allowing air to enter the system while suppressing the loud noise of air mass release. This mediator enables the circulation cycle to complete while reducing noise disturbance to acceptable levels.
6Quantity of substance
If filtering materials are arranged in overlapping manner, then filtering tank is filled, but cleaning and maintenance becomes difficult requiring more time
Solution Approach 1:
Filtering materials are segmented into distinct layers within the filtering tank, with each layer contained in a separate removable basket. This segmentation maintains full filtering material volume for effective treatment while enabling easy maintenance by allowing individual baskets to be removed and cleaned without disassembling the entire system.
7Productivity
If air pump is used to add oxygen to filtering tank, then complete water treatment is achieved, but energy consumption and installation complexity increase
Solution Approach 1:
The system uses self-service aeration through the bell siphon mechanism, which naturally creates water movement and air contact during its circulation cycles. This eliminates the need for external air pumps, achieving complete water treatment through the system's own operational dynamics rather than additional energy-consuming equipment.
Solution Approach 2:
The bell siphon utilizes hydraulic and pneumatic principles to create natural water circulation and aeration. The siphon action draws air into the water stream, providing oxygenation without mechanical pumps, thus achieving complete water treatment while avoiding additional energy consumption.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
These tanks achieve complete water treatment with higher water circulation rates, reduce noise by over 70%, enable efficient maintenance, and eliminate the need for oxygen pumps, resulting in improved water quality and energy savings.
Implementation Method 1
This is done by using a low-level bell siphon and a small stand water outlet pipe. These allow the siphoning of water out of the said tray
Implementation Method 2
The inventor can control the remaining water inside the tanks to the desired level through the use of a U-turn shape snock pipe (20). The said pipe also reduces the loud sounds caused from the stop of the siphoning due to the air mass.
Implementation Method 3
Water is released into the filtering tanks through filtering materials such as volcanic stones, filtering fibers, etc. and then further released from the filtering tanks.
