Solution Overview
Problem
Existing CO2 supply methods for aquariums, such as CO2 pressure cartridges and biological fermentation systems, face challenges like irregular CO2 production, underdosing, and difficulties in reliable pH regulation, which can harm fish health.
Innovation Solution
An aquarium pressurized gas container CO2 generating composition comprising dextrose and yeast is used to generate CO2 gas in a tank, allowing for rapid and uniform CO2 release. This composition includes specific yeast strains and additives like trace elements, minerals, and diammonium phosphate to enhance fermentation efficiency and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional fermentation systems with sucrose and yeast are used, then CO2 can be produced on-site without pressure cartridges, but the fermentation process is irregular and starts several days after mixing, causing unreliable CO2 dosing and underdosing
Solution Approach 1:
The patent changes the chemical parameters of the fermentation system by replacing sucrose with dextrose monohydrate and adjusting yeast concentration to 0.5-2.0 g/L. These parameter changes enable rapid fermentation start (within hours rather than days) and consistent CO2 production rates, resolving the reliability issue while maintaining on-site production capability
Solution Approach 2:
The patent prepares the fermentation composition in advance with pre-determined optimal ratios of dextrose monohydrate (20-40 g/L) and yeast (0.5-2.0 g/L), along with pH buffers and nutrients. This preliminary preparation ensures that when activated, the system immediately produces CO2 at consistent rates without the delayed and irregular start-up period of traditional sucrose-based systems
2Reliability
If CO2 pressure cartridges are used, then reliable CO2 supply can be achieved, but safety regulations must be observed during storage, operation and transport, and cartridges containing more than 50 grams of CO2 cannot be stored centrally
Solution Approach 1:
The patent extracts the CO2 generation function from pressurized cartridges and relocates it to a fermentation-based chemical system that operates at atmospheric pressure. By taking out the high-pressure storage requirement and replacing it with a controlled chemical reaction system, the invention eliminates safety regulation constraints on storage and transport while maintaining reliable CO2 supply
Solution Approach 2:
The patent introduces a fermentation composition as an intermediary substance that converts chemical energy stored in dextrose monohydrate into CO2 gas through controlled microbial fermentation. This intermediary approach allows CO2 to be generated on-demand from stable, non-regulated chemical precursors, avoiding the need to store regulated pressurized CO2 cartridges
3Ease of operation
If fermentation systems are used to produce CO2, then no pressure cartridges need to be filled and transported, but the fermentation process is irregular and only starts several days after sucrose and yeast come into contact, creating risk of incorrect CO2 dosing
Solution Approach 1:
The patent changes key parameters of the fermentation system: replacing sucrose with dextrose monohydrate (which ferment faster), optimizing yeast concentration to 0.5-2.0 g/L, and adjusting substrate concentration to 20-40 g/L. These parameter changes reduce fermentation start time from several days to hours and enable precise, consistent CO2 dosing rates suitable for aquarium applications
Solution Approach 2:
The patent replaces the mechanical cartridge filling and distribution system with a chemical fermentation system that generates CO2 in-situ. By substituting the mechanical delivery mechanism with a controlled biochemical reaction, the system achieves both ease of operation (no filling/transport) and dosing precision (through controlled fermentation kinetics)
