Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for varying buoyancy, such as using compressed gas tanks or electrolysis, face challenges like space consumption, safety concerns, and high power requirements, making them unsuitable for battery-powered applications or those requiring energy efficiency.
Innovation Solution
A technique involving a substrate configured to produce gas on demand when exposed to a liquid, where the substrate is exposed to the liquid and the produced gas is captured to increase the buoyancy of an apparatus within a fluid, eliminating the need for compressed gas tanks and reducing power requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If compressed gas tanks or cartridges are used to vary buoyancy, then buoyancy can be increased, but the apparatus consumes considerable space and raises safety concerns due to pressurized containers
Solution Approach 1:
The invention extracts the gas generation process from pre-compressed storage and performs it in-situ within the apparatus by mixing liquid and substrate, eliminating the need for external compressed gas tanks and their associated safety and space issues
Solution Approach 2:
The invention introduces liquid and substrate as intermediary materials that react to produce gas on-demand, replacing the direct use of stored compressed gas and thereby resolving the contradiction between safety and space consumption
2Volume of moving object
If conventional electrolysis is used to produce gas on-demand, then less space is required, but a great deal of power is required making it unsuitable for battery-powered applications
Solution Approach 1:
The invention replaces the electrical/mechanical electrolysis system with a chemical reaction system involving liquid and substrate mixing, thereby eliminating high power requirements while maintaining on-demand gas production and space efficiency
Solution Approach 2:
The invention changes the fundamental parameter of gas production from electrical-driven electrolysis to chemical-driven reaction, dramatically reducing energy consumption while preserving the space-efficient on-demand generation capability
3Reliability
If compressed gas tanks are used, then buoyancy can be varied, but the pressurized containers can rupture creating safety hazards
Solution Approach 1:
The invention removes the pressurized container element entirely from the system by generating gas through chemical reaction rather than storage, thereby eliminating both the safety hazard of rupture and the complexity of pressurized vessel management
Applied Scientific Principles

Function Achieved in This Case
This approach allows for efficient variation of buoyancy without the need for large power sources or compressed gas tanks, enhancing safety and reducing weight, making it suitable for battery-powered applications and those requiring energy efficiency.
Implementation Method 1
the substrate produces the gas using a passive reaction, which proceeds spontaneously once the substrate is exposed to the liquid
Implementation Method 2
capturing the gas produced by the substrate to increase the buoyancy of the apparatus within a fluid

AI summary
A technique for varying buoyancy of an apparatus includes providing a substrate configured to produce gas on demand when exposed to a liquid, exposing the substrate to such liquid, and capturing the gas produced by the substrate to increase the buoyancy of the apparatus within a fluid. In some examples, the liquid and the fluid contain the same material, such that gas may be produced using fluid already in the environment.
