Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the power storage unit is installed in a fixed position within the body frame, then the structural stability is improved, but the ease of maintenance deteriorates
Solution Approach 1:
The body frame is divided into a first frame and a second frame that can swing relative to each other about a first swing axis. The power storage unit is detachably mounted on the second frame, allowing the second frame to be swung away from the first frame to provide access to the power storage unit for maintenance, while maintaining structural stability during normal operation.
Solution Approach 2:
The connection between the first frame and second frame is made dynamic through a swing mechanism, allowing the second frame to rotate about a first swing axis. This enables the power storage unit to be accessed by swinging the second frame away, while maintaining a stable fixed position during normal operation.
2Ease of repair
If the power storage unit is made detachable for easy maintenance, then the ease of repair is improved, but the device complexity increases
Solution Approach 1:
The detachable mounting structure divides the power storage unit and its mounting bracket as a separable module from the main body frame. This modular segmentation allows the power storage unit to be easily detached and reattached without complex disassembly procedures, maintaining simplicity while enabling easy maintenance.
Solution Approach 2:
Instead of making the entire body frame detachable, only the portion containing the power storage unit (the second frame) is made detachable through the swing mechanism. This partial action provides easy maintenance access while minimizing the increase in overall device complexity.
3Volume of moving object
If the support frame is positioned above the body frame, then the space utilization is improved, but the ease of access for maintenance deteriorates
Solution Approach 1:
The support frame is made dynamically positionable through the swing mechanism connecting the first frame and second frame. During normal operation, the support frame is positioned above the body frame for compact space utilization. During maintenance, the second frame can be swung away to provide easy access to the power storage unit, temporarily reconfiguring the spatial arrangement.
Solution Approach 2:
The support structure is segmented into the first frame, second frame, and support frame as separate but connected components. This segmentation allows the second frame to be independently swung away from the first frame while the support frame remains positioned above, enabling maintenance access without compromising overall space utilization.

AI summary
Multiple wheels include at least one drive wheel drivable by a drive source. A body frame includes first and second frames aligned in a front-rear direction. A transport vehicle includes a first connector connecting the first frame to the second frame to allow the frames to swing about a first swing axis extending in a width direction, a second connector connecting the first frame to the support frame to allow the frames to swing about a second swing axis extending in the width direction, and a third connector connecting the second frame to the support frame to allow the frames to swing about a third swing axis extending in the width direction and to slide in the front-rear direction. A power storage unit is supported by the support frame attachably to and detachably from the support frame from a first side in the front-rear direction or in the width direction.
