Design and simulation of a multifunctional care bed

As the aging of the population intensifies, how to better care for bedridden elderly or patients with physical disabilities has become an urgent issue. This paper focuses on the design of a multifunctional care bed, which can help patients realize functions such as back elevation, leg bending, turning, toileting, and bathing. First of all, we designed the overall structure of the care bed to ensure the realization of each function. Then, the care bed model was built by using SOLIDWORKS, and the dynamic analysis and mechanical analysis of the care bed mechanism were carried out by using this model. According to the dynamic analysis, we obtained the motion change curve of the care bed under different functions. we conducted a finite element analysis of the important mechanisms of the care bed, and tested the strength of its parts. The results show that each mechanism operates stably and the experimental value is much smaller than the yield strength of the material. Consequently, it could meet the design requirements and bring convenience to the people.
