Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If wheel propulsion systems are used, then the vehicle can travel along the guideway, but energy efficiency is limited due to high friction
Solution Approach 1:
The patent replaces traditional wheel-based mechanical propulsion with a magnetic propulsion system. The vehicle uses magnetic fields generated by coils to propel itself along the guideway, eliminating the need for physical contact between wheels and track. This substitution of mechanical contact with magnetic field interaction directly reduces friction and improves energy efficiency.
2Use of energy by moving object
If magnetic propulsion systems are used, then energy efficiency improves, but the system becomes complicated requiring complex coils to be energized
Solution Approach 1:
The guideway is divided into multiple segmented coil sections, each independently controllable. This segmentation allows the propulsion system to energize only the necessary coils at any given time, simplifying the control system and reducing overall complexity while maintaining efficient magnetic propulsion.
Solution Approach 2:
The magnetic propulsion system uses periodic energizing of coils along the guideway to create a sequential magnetic field that propels the vehicle forward. This periodic activation pattern simplifies the control logic compared to maintaining continuous magnetic fields, as coils are energized only when needed for propulsion.
3Use of energy by moving object
If low-friction systems are used, then energy efficiency improves, but traction is limited reducing capacity for traveling along steep grades
Solution Approach 1:
The patent replaces mechanical wheel-rail contact with magnetic field interaction for both propulsion and traction. The magnetic coils generate electromagnetic forces that can provide sufficient traction for steep grades without requiring physical friction-based contact, thereby maintaining both low friction and high traction capability.
