Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If conventional internal combustion engines are used, then the engine structure is simple, but the energy conversion efficiency is low
Solution Approach 1:
The patent replaces the conventional mechanical crankshaft connection with an electromagnetic converter system. The piston is connected to the crankshaft via an electromagnetic converter that can convert mechanical energy to electrical energy and vice versa, enabling bidirectional energy conversion and improving overall energy efficiency while maintaining structural feasibility
Solution Approach 2:
The electromagnetic converter serves multiple functions: it acts as both a mechanical-to-electrical energy converter during the power stroke and an electrical-to-mechanical energy converter during intake, compression, and exhaust strokes. This multi-functionality addresses the energy conversion efficiency problem while integrating seamlessly into the existing engine structure
2Adaptability or versatility
If the engine operates under varying conditions, then the adaptability is improved, but the thermal management becomes more difficult
Solution Approach 1:
The patent incorporates an energy management system that monitors operating conditions and adjusts the electromagnetic converter operation accordingly. This feedback mechanism enables the engine to adapt to varying loads, speeds, and fuel compositions while the thermal controller monitors and manages temperature levels, allowing adaptive operation with improved thermal control
Solution Approach 2:
The electromagnetic converter provides dynamic control over energy conversion timing and magnitude, allowing the engine to optimize performance across varying operating conditions. The converter can adjust its operation in real-time based on engine state, enabling better thermal management through controlled energy conversion cycles
3Duration of action of moving object
If the piston stroke is extended to improve power output, then the power stroke duration is increased, but the engine complexity increases
Solution Approach 1:
The patent replaces the traditional mechanical crankshaft with an electromagnetic converter system that enables extended power stroke duration. The electromagnetic field can maintain force application over longer distances without the mechanical constraints of a crankshaft, allowing extended power strokes while actually reducing overall structural complexity by eliminating the crankshaft assembly
