Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a two-wheel electric vehicle uses a conventional propulsion system for water movement, then the propulsion unit size and cost increase, but the vehicle can move on water
Solution Approach 1:
The flywheel serves multiple functions: it acts as both the rotation mass for gyroscopic stabilization and the propulsion element for water movement. By integrating the propulsion function into the existing flywheel structure, the patent eliminates the need for a separate propulsion unit, thereby reducing size and cost while maintaining water mobility capability
Solution Approach 2:
The patent combines the stabilization function and propulsion function into a single integrated system. The flywheel's rotational mass is used for both maintaining vehicle balance through gyroscopic effect and generating thrust for water movement, merging two separate systems into one
2Device complexity
If the gimbal shafts are fixed in a single direction, then the structure is simpler, but the oscillation reduction effectiveness decreases
Solution Approach 1:
The gimbal shafts are designed to be rotatable rather than fixed, allowing the system to dynamically adapt to different oscillation conditions. The ability to switch between parallel and intersecting configurations enables the gimbal to optimally counteract various types of vehicle oscillations while maintaining manageable structural complexity
Solution Approach 2:
The stabilization system is divided into multiple gimbal shafts that can independently rotate and adjust. This segmentation allows each shaft to address specific oscillation components, with the combined effect providing comprehensive oscillation reduction across different axes and conditions

AI summary
A two-wheel mobile apparatus that is movable on land and water includes a cabin and a propulsion unit. The cabin is configured to be watertight to a height above a waterline when the mobile apparatus moves on water. Further, the cabin accommodates an occupant and isolates the occupant from the outside of the cabin. The propulsion unit includes a rotatably driven impeller and moves the mobile apparatus on water. An orientation detection unit that detects orientation of the mobile apparatus. A tilt correction unit corrects tilt of the mobile apparatus on land. An oscillation reduction unit reduces oscillation of the mobile apparatus on water. An orientation control unit switches between actuation of the tilt correction unit and actuation of the oscillation reduction unit based on a detection value of the orientation detection unit.
