Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple transport devices are used to transport a locomotive with two bogies, then the transport capacity is sufficient, but the device complexity and transport cost increase
Solution Approach 1:
The patent combines multiple wheel set receiving spaces into a single transport device, allowing one device to accommodate multiple wheel sets from different bogies. This merging of functions enables a single transport device to handle what previously required multiple devices, thereby reducing overall system complexity while maintaining transport capacity
Solution Approach 2:
The transport device is designed with universal receiving spaces that can accommodate wheel sets from various bogie configurations. The standardized interface and flexible positioning system allow the same device to handle different wheel set arrangements, making it a multi-functional solution that replaces multiple specialized devices
2Productivity
If transport devices move at high speeds, then transport efficiency improves, but the risk of derailment increases due to stability concerns
Solution Approach 1:
The mounting plate is designed to be movably connected to the frame, allowing it to dynamically adjust its position and orientation in response to forces encountered during high-speed transport and cornering. This dynamic adaptation maintains optimal contact between the wheel sets and receiving spaces, preventing derailment while enabling high-speed operation
Solution Approach 2:
The system changes the operational parameters of the mounting plate, transitioning from a fixed rigid connection to a movable flexible connection. This parameter change allows the mounting plate to absorb and accommodate dynamic forces during high-speed transport and curve negotiation, maintaining stability and preventing derailment
3Strength
If the mounting plate is rigidly connected to the frame, then structural strength improves, but the transport device cannot safely navigate curves at high speeds
Solution Approach 1:
The mounting plate employs a movable connection to the frame that allows dynamic adjustment during cornering operations. This dynamic capability enables the mounting plate to adapt to lateral forces and maintain proper alignment of wheel sets during high-speed curve negotiation, while still providing sufficient structural support
4Device complexity
If conventional transport devices are used, then the transport system is simple, but the transport speed is limited to low speeds for safety reasons
Solution Approach 1:
The patent changes the fundamental parameter of the mounting plate connection from fixed to movable, enabling high-speed operation while maintaining safety. This single parameter change allows the transport device to operate at speeds of 60-100 km/h without compromising stability or requiring complex additional safety systems
