Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional coaxial drive system is used, then the structure is simple and easy to manufacture, but the vehicle design flexibility and performance characteristics are limited
Solution Approach 1:
The drive system is segmented into separate functional components: a propulsion source, a non-axial transmission mechanism with gear assembly, and wheels. This segmentation allows independent optimization of each component and enables flexible configuration arrangements that were not possible with traditional coaxial systems.
Solution Approach 2:
The patent transitions from axial (one-dimensional) power transmission to non-axial (multi-dimensional) power transmission. The transmission mechanism transfers rotational power from the propulsion source through angular offsets and non-collinear arrangements, enabling versatile vehicle configurations including varying wheel positions, orientations, and propulsion source locations.
2Reliability
If wheel tension is made adjustable through a tensioning system, then traction and stability improve, but the device complexity increases
Solution Approach 1:
The tensioning system enables dynamic adjustment of wheel tension rather than fixed static tension. This allows the vehicle to adapt wheel tension levels based on operating conditions, terrain, and cargo weight, improving traction and stability while maintaining a relatively simple mechanical adjustment mechanism.
3Stability of the object's composition
If a stabilization system with counterweight and sensors is added, then vehicle orientation control improves, but the weight and complexity of the vehicle increase
Solution Approach 1:
The stabilization system employs a counterweight that can be positioned to offset vehicle tilting and maintain horizontal orientation. The counterweight acts as a balancing mass that compensates for disturbances, providing passive stabilization that reduces the need for complex active control systems and heavy sensor arrays.
Solution Approach 2:
The stabilization system incorporates sensors that detect vehicle orientation and tilt, providing feedback to a control mechanism that adjusts the counterweight position. This closed-loop feedback control enables precise orientation maintenance while using minimal counterweight mass, reducing overall vehicle weight compared to purely passive or purely active systems.
