Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If traditional fossil fuel engines are used for ship propulsion, then sufficient power is generated, but CO2 emissions increase and environmental harm occurs
Solution Approach 1:
The patent replaces the traditional fossil fuel combustion engine with an osmosis-based propulsion system. The osmosis chamber uses the natural osmotic pressure difference between saltwater and freshwater to drive water flow, which mechanically propels the ship without combustion, thereby eliminating CO2 emissions while maintaining propulsion capability
Solution Approach 2:
The invention changes the fundamental operating parameter from chemical energy combustion to physical osmotic pressure. By utilizing the salinity difference parameter (high salinity area vs. low salinity area separated by semipermeable membrane), the system generates propulsion force without harmful emissions
2Power
If osmosis chamber is designed with high pressure capability, then propulsion efficiency increases, but device complexity increases
Solution Approach 1:
The osmosis chamber is segmented into distinct functional areas: high salinity area, low salinity area, and semipermeable membrane separation zone. This segmentation allows each component to be optimized independently for its specific function while working together to generate propulsion power
Solution Approach 2:
The osmosis chamber serves multiple functions simultaneously: it acts as a pressure generation device, a fluid separation system, and a propulsion engine. The high salinity and low salinity areas work together to create osmotic pressure that directly drives ship movement, reducing the need for separate mechanical components

Function Achieved in This Case
This system provides a sustainable and environmentally friendly means of propulsion, utilizing abundant seawater resources to generate power, reducing CO2 emissions, and offering a renewable energy solution.
Implementation Method 1
The osmotic membrane (13) allows the passage of water from the low salinity area (12) to the high salinity area (11), but not the passage of salt ions dissolved in the water
Implementation Method 2
it has continuous capillary channels (153), into which water penetrates due to capillary forces and van der Waals forces and is transported from the low salinity area (12) to the osmotic membrane (13)
