Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If axles are made thin to reduce weight, then weight is reduced, but support rigidity of wheels deteriorates
Solution Approach 1:
The axle support system is segmented into multiple axles (first axle and second axle) that independently support different wheels. This segmentation allows each axle to be optimized for its specific function, enabling the use of thinner, lighter axles while maintaining overall support rigidity through the distributed multi-axle configuration.
Solution Approach 2:
Different axles are designed with different local qualities - the first axle has a first thickness and the second axle has a second thickness, allowing each axle to be optimized for its specific load requirements. This local optimization enables weight reduction while maintaining necessary support rigidity at each wheel position.
2Weight of moving object
If axles are made thin to reduce weight, then weight is reduced, but stability during landing and flight deteriorates
Solution Approach 1:
The wheel support system is divided into multiple independent axle-wheeled bodies, where each axle supports specific wheels. This segmentation creates a more stable distributed support structure that reduces oscillation during flight and landing, while allowing each individual axle to be lighter.
Solution Approach 2:
Multiple axles and wheels are combined into an integrated frame structure where the first axle body and second axle body are both coupled to the same frame. This merging creates a unified stable platform that reduces oscillation while allowing weight optimization of individual components.
3Adaptability or versatility
If multiple wheels are added to improve mobility, then mobility performance is improved, but device complexity increases
Solution Approach 1:
The axles serve multiple functions - they support wheels for ground mobility, provide structural coupling to the frame, and act as rotation axes. This multi-functionality reduces the need for separate components, simplifying the overall structure while enabling multiple wheels for improved mobility.
Solution Approach 2:
The axle structure merges the wheel support function, rotation function, and frame coupling function into a single integrated component. This merging reduces the number of separate parts needed, simplifying the device while enabling multi-wheel configuration for enhanced mobility performance.
