Abstract

For the development of multi-functional assistive devices, a new methodological approach is proposed based on the principle of their parallel design. Traditionally, such devices are created by the human musculoskeletal system functions, assisting theserial solution of the task: the leg balancing during walking, the body balancing during sit-to-stand; and their functional abilities are extended by overlaying the developed technical solutions. The new approach provides the device multi-functionality at its conceptual design stage byincreasing themobility degrees and assumes the use of the same elements for realizingvarious functions. With this, the number of elements is reduced and, as a result, new advantages are gained, such as mobility, the opportunity of balancing a greater number of the humanbody segments, at the same time assisting the balancing of the biomechanical system of the body, and the assisting device in general. The proposed approach illustrated on a specific example of a new assistive device development, provides a human and device biomechanical system total static balancing during a human`s walking and sitting. The achieved main advantages of the device are its universality, compactness, adjustability and comfort in comparison with the known analogues. The designed device can be used both for assisting the human musculoskeletal system, and physiotherapy. At the same time, the device also provides the dosing of the loads and angular displacement ranges, hence, greater efficiency in human physiotherapy. The proposed approach to the human musculoskeletal system assisting multi-purpose balanced device design is quite universal and can be used for designing not only assisting, but also for other similar - purpose portable rehabilitation devices.
