Problem
Existing fish tank systems require frequent water changes to maintain water quality, which is costly and inconvenient, leading to rapid fish death due to deteriorating water conditions and lack of experience in water management.
Innovation Solution
A water-changing-free terrarium with a pipeline type biofiltration system that includes a terrarium body, box body, partitions, filtration assembly, and modified filter material, which filters and decomposes impurities, allowing purified water to recirculate and maintain internal water circulation purification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If water is not changed for a long time, then water saving and reduced management effort are achieved, but water quality deteriorates with accumulation of food residues, excrement, water mold and algae
Solution Approach 1:
The system enables automatic water purification through self-service mechanisms. The water circulation pump automatically circulates water through the filtration system, and the biofiltration system automatically decomposes organic waste. The heater maintains water temperature automatically, creating a self-regulating ecosystem that purifies water without human intervention, thus extending the interval between water changes while maintaining water quality.
Solution Approach 2:
The patent transforms water quality management from periodic replacement to continuous parameter control. By monitoring and controlling parameters such as water circulation rate, filtration efficiency, and biological decomposition processes, the system maintains stable water quality parameters (ammonia nitrogen, nitrite, pH) over extended periods, eliminating the need for frequent water changes while preventing quality deterioration.
2Object-affected harmful factors
If a pipeline type biofiltration system is added, then water purification capability is improved, but device complexity increases
Solution Approach 1:
The patent merges multiple functions into integrated components. The filtration assembly combines physical filtration media with biofiltration materials in a single unit. The water circulation system integrates the pump, pipelines, and filtration chambers into a unified circulation loop. The heating element is integrated into the tank structure. These merged components reduce overall system complexity while maintaining comprehensive water purification capabilities.
Solution Approach 2:
The patent introduces intermediary elements that simplify system operation. The filtration assembly acts as an intermediary between the water environment and the biological decomposition processes. The pipeline system serves as an intermediary conduit that directs water flow through different treatment zones. These intermediaries translate complex purification processes into simple, maintainable system components.
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
The system effectively filters and decomposes floating debris, fish manure, and residues, maintaining stable water quality without manual water changes, ensuring healthy fish growth and clear water for an extended period.
Implementation Method 1
a water pump, a horizontal pipeline, multiple vertical pipelines, an outlet pipe and a pipeline... The water pump is disposed on a left side of the first partition, and is fixedly connected to the bottom of the box body, and a water inlet of the water pump is in communication with the filtration groove through the pipeline
Implementation Method 2
A filtration groove is defined between the first partition and the second partition, and the filtration groove is provided with the filtration cotton therein... through the filtration assembly on the bottom of the terrarium, most impurities such as floating objects, fish droppings and residues in the water are filtered
Implementation Method 3
a right side of the second partition is filled with a modified filter material... which filters and decomposes impurities such as floating debris, fish manure, and residues in water

AI summary
A water-changing-free terrarium with pipeline type biofiltration system is provided, which includes: a terrarium body; a box body, disposed in the terrarium body and fixedly connected to a bottom of the terrarium body; a filtration assembly, disposed in the box body. The box body is provided with a first partition and a second partition therein, which are perpendicular to a bottom of the box body, and the first partition and the second partition are fixedly connected to the bottom of the box body. A filtration groove is defined between the first partition and the second partition, and is provided with filtration cotton therein. Through the filtration assembly, most impurities in the water are filtered and decomposed in the modified filter material. The purified water flows back to the terrarium through the outlet pipe, and other undecomposed impurities are adsorbed on the filtration cotton, which is beneficial for subsequent centralized cleaning.
