Solution Overview
Problem
Conveying apparatuses face challenges in stabilizing the conveyance of carts with large weights, as existing systems struggle to maintain stability and traction, leading to potential instability and cargo collapse.
Innovation Solution
A conveying apparatus with a base, rotatable wheels connected via a suspension mechanism, a lifter, and a control unit that detects lower side distance to lift and lower the lifter, supporting a part of the cart's weight and enabling stable conveyance by controlling wheel rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the weight of the conveyance target is increased, then the carrying capacity is improved, but the stability of conveyance deteriorates
Solution Approach 1:
The patent segments the weight support function between the ground (through wheels) and the lifter mechanism. The lifter supports a predetermined proportion (e.g., 50%) of the conveyance target's weight, while the remaining weight is supported by the ground through the wheels, dividing the load-bearing responsibility to maintain stability with heavy loads
Solution Approach 2:
The system dynamically adjusts the lifter's support force based on the detected lower side distance, changing the parameter of support force to maintain optimal conveyance stability. The control unit modulates the lifter's lifting force to support a predetermined proportion of the total weight, adapting to different load conditions
2Stability of the object's composition
If the lifter supports more weight, then the stability of conveyance is improved, but the risk of cargo collapse increases
Solution Approach 1:
The lifter is designed to support only a predetermined proportion (partial action) of the conveyance target's weight rather than the full weight. This partial support is sufficient to improve stability while avoiding excessive lifting force that could cause cargo collapse or damage to the conveyance target
3Adaptability or versatility
If the wheel is connected via suspension mechanism, then the adaptability to terrain is improved, but the complexity of the device increases
Solution Approach 1:
The suspension mechanism is implemented as a separate, modular component connecting the wheel to the base, segmenting the shock-absorbing function from the main conveying structure. This modular approach adds terrain adaptability while keeping the overall device architecture relatively simple and maintainable

AI summary
In embodiments, a conveying apparatus includes a base, a wheel, a lifter, a lower side distance detection unit, and a control unit. The wheel is connected to the base via a suspension mechanism and is rotatable. The lifter is able to be lifted and lowered with respect to the base in a direction of a conveyance target. The lower side distance detection unit detects a lower side distance between a reference surface of the base and a ground contact surface of the wheel. The control unit controls a lifting/lowering operation of the lifter and rotative driving of the wheel. The control unit causes the lifter to be lifted and lowered based on the lower side distance and to support a part of a weight of the conveyance target, and causes the wheel to be rotatively driven and to convey the conveyance target.
