Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If a combustion engine and power generator are installed in an electric vehicle to extend mileage range, then the mileage range is increased, but the vehicle interior space is reduced
Solution Approach 1:
The power generation system is divided into two separate power generators (9a, 9b) positioned at opposite ends of the engine shaft, allowing distributed placement that optimizes space utilization within the vehicle while maintaining power generation capability
Solution Approach 2:
The engine shaft is oriented at right angles to the cylinders with extremities protruding from the engine body, allowing power generators to be positioned in opposite directions perpendicular to the cylinder axes, thereby utilizing three-dimensional space more efficiently and reducing the overall footprint in the vehicle
2Duration of action of moving object
If a combustion engine and power generator are installed in an electric vehicle to extend mileage range, then the mileage range is increased, but the apparatus dimensions are increased
Solution Approach 1:
The power generation system is segmented into two separate power generators (9a, 9b) positioned at opposite ends of the engine shaft, allowing the system to be more compact and better integrated into the vehicle structure while maintaining power generation capability
Solution Approach 2:
The combustion engine and two power generators are integrated into a single compact assembly where the engine shaft directly drives both generators, reducing the need for separate mounting structures and minimizing overall apparatus dimensions
