Solution Overview
Problem
Existing weight-bearing devices for carrying loads over long distances are often strenuous and potentially dangerous for users, as they lack efficient mechanisms for balancing and transporting heavy loads across varied terrain.
Innovation Solution
A weight-bearing device featuring a single wheel connected to a frame with a motor-driven gear system, a support plate with alignment slots, and handles for user control, allowing for balanced load transport over rough terrain.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a weight-bearing device uses a single wheel with motor assistance to transport heavy loads, then the user effort and fatigue are reduced, but the device complexity increases due to the motor and alignment mechanisms
Solution Approach 1:
The patent replaces manual mechanical effort with an electric motor system. The motor is connected to the wheel through a gear mechanism, substituting human physical effort with automated mechanical assistance. This directly reduces user fatigue while transporting heavy loads over long distances.
Solution Approach 2:
The patent introduces alignment tabs and alignment slots as intermediary components between the frame and support plate. These intermediaries ensure proper positioning and balanced load distribution, enabling the motorized system to function effectively while managing the complexity through standardized connection mechanisms.
2Stability of the object's composition
If the device uses alignment tabs and slots to balance the load over the wheel, then the transport stability is improved, but the device complexity increases due to additional alignment components
Solution Approach 1:
The alignment tabs and slots create an equipotential connection system that ensures the support plate is properly positioned relative to the frame. This alignment mechanism balances the load distribution over the wheel, achieving stable transport configuration through standardized connection points.
3Productivity
If the device is designed for long-distance transport of heavy loads, then the productivity is improved, but the user fatigue and injury risk increase
Solution Approach 1:
The electric motor system replaces human mechanical effort for long-distance transport. The motor provides continuous assistance over extended distances, enabling productivity improvement while eliminating the harmful effect of user fatigue that would occur with manual carrying.
Solution Approach 2:
The device incorporates a motorized drive system that provides dynamic assistance during transport. The motor can be engaged or disengaged as needed, providing adaptive support that maintains productivity while managing user fatigue levels throughout the transport journey.

AI summary
A rescue device includes a support plate connected to a rescue basket. The support plate includes one or more alignment slots. One or more alignment tabs on a weight transfer member of a frame are inserted into the alignment slots to align the support plate on the frame. An extension member connected to the frame moves a set of handles away from the frame to accommodate the rescue basket. A wheel on the frame is driven by a motor to facilitate the rescue of individuals.
