Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If balance-assisting systems are incorporated to stabilize the vehicle, then stability is improved, but device complexity increases
Solution Approach 1:
The balance-assisting system is divided into independent modular components: sensors (accelerometers, gyroscopes) for detection, a control unit for processing, and motorized drive elements for actuation. This segmentation allows each component to be optimized independently and simplifies maintenance and replacement.
Solution Approach 2:
The balance-assisting system serves multiple functions: it detects vehicle tilt through sensors, processes this information to determine appropriate corrective actions, and actuates ground-contacting members to restore stability. This multi-functionality reduces the need for separate stabilization mechanisms.
2Stability of the object's composition
If balance-assisting systems with multiple sensors and actuators are used, then stability control is improved, but manufacturing cost increases
Solution Approach 1:
Multiple sensor types (accelerometers and gyroscopes) are integrated into a single control unit that processes all balance-related data. The motorized drive elements are combined with the ground-contacting members, eliminating the need for separate actuation mechanisms and reducing overall system cost.
Solution Approach 2:
The control unit automatically processes sensor data and adjusts the ground-contacting members to maintain stability without requiring external intervention or complex calibration procedures, reducing manufacturing and maintenance costs.
3Ease of operation
If the vehicle uses an unstable design to enable maneuverability, then ease of operation is improved, but stability deteriorates
Solution Approach 1:
The vehicle transitions between unstable and stable states dynamically. During normal operation, the vehicle maintains an unstable configuration for ease of maneuvering. When tilt exceeds thresholds detected by sensors, the balance-assisting system activates to restore stability, creating a dynamic balance between maneuverability and stability.
Solution Approach 2:
Sensors continuously monitor the vehicle's orientation and provide feedback to the control unit. This feedback loop enables the system to detect instability caused by user maneuvers and automatically correct it, allowing the vehicle to remain easy to operate while maintaining stability during operation.
