Abstract

Currently, with the improvement of people's living standards and the intensification of population aging, the demand for assisted dining is becoming increasingly urgent. Therefore, targeting vulnerable groups as the audience and based on the theoretical foundations of mechanical manufacturing technology and mechanical design, a multifunctional assisted dining cart has been designed. Its structure is rational and its functions are comprehensive, capable of meeting the various needs of the elderly and the disabled during the dining process, thereby enhancing their dining experience. This paper mainly employs a scissor-type hydraulic lifting device to design the internal structure of the cart body. The top of the cart is connected by deep groove ball bearings. The design of the mechanical arm and the mechanical claw also work in coordination, enabling the completion of all task instructions within the spatial range. The motion device adopts the original push-pull method to reduce costs and control the distribution of resources. Ultimately, the complete design framework of the multifunctional assisted dining cart is derived.
