Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If internal combustion engines are used to power marine vessels, then power and speed are achieved, but harmful exhaust gases and environmental pollution are produced
Solution Approach 1:
The patent replaces the internal combustion engine (mechanical/chemical system) with an electric motor (electrical system). The electric motor converts electrical energy from battery packs directly to mechanical rotation of the propeller, eliminating the need for fuel combustion and thereby eliminating harmful exhaust gas emissions while maintaining propulsion capability.
Solution Approach 2:
The patent changes the energy source parameter from chemical energy (fuel) to electrical energy (battery). This fundamental parameter change transforms the propulsion system from a polluting internal combustion system to a clean electric system, resolving the contradiction between power delivery and environmental harm.
2Object-affected harmful factors
If internal combustion engines are used to power marine vessels, then propulsion power is generated, but noise is produced
Solution Approach 1:
The patent substitutes the noisy internal combustion engine with a quiet electric motor. Electric motors operate significantly quieter than combustion engines because they lack moving parts like pistons, valves, and spark plugs that generate mechanical noise, thereby reducing acoustic pollution while maintaining propulsion function.
3Power
If fuel-based engines are used to power marine vessels, then power and torque are produced, but mass and complexity increase
Solution Approach 1:
The patent extracts and eliminates the heavy components associated with fuel-based engines, including the engine block, fuel tank, exhaust system, and associated mechanical linkages. By removing these unnecessary components and replacing them with a compact electric motor and battery system, the overall mass of the propulsion system is reduced while maintaining power and torque output.
