| With the deepening of the aging population and the introduction of Internet thinking in the field of elderly care,the demand and development of smart wheelchairs have received widespread attention.At present,most smart wheelchairs on the market have a single function,lag in intelligence,and lack design aesthetics and attention to user experience.Based on the service design theory and method,this article studies the design of intelligent wheelchairs,improves the appearance of the design,enhances the functionality and safety of the structure,and builds a humanized service platform.The main research contents are as follows:1.Market research and analysis of smart wheelchairs.A comparative study of smart wheelchair brands and online related service apps.Using quantitative analysis and qualitative analysis to conduct user research,extract the influencing factors of the needs of middle-aged and elderly users in the use of wheelchairs,and create user portraits,so as to locate the target users and user needs of smart wheelchairs.2.Based on the relevant theories of perceptual engineering,design and study the shape of the elderly smart wheelchair.Construct a product perceptual image evaluation system through semantic difference method,KJ method and factor analysis method,carry out hierarchical analysis and inference from the three factors of shape,color and material,apply it to the shape design of elderly smart wheelchairs,and use Rhino software to model Get the product design,and get the best plan with the help of expert evaluation method.3.Based on ergonomics,design and study the structure of the elderly intelligent wheelchair.Calculate the structural dimensions of the intelligent wheelchair seat,track,backrest and front legs through the three indicators of structure,function and mobility.Through the Ansys software,the strength of the key parts of the wheelchair mechanism in various postures is numerically simulated,the stress and strain of the key parts are analyzed,and the stability of the center of gravity of the wheelchair is analyzed and calculated to obtain a structural scheme that meets the design needs.4.Use service design methods to optimize the elderly care service platform for the disabled.Integrate and connect communities,hospitals,service providers,relatives and friends,and provide services to the elderly in health,emotion,entertainment,shopping,and social aspects to meet the needs of the elderly at multiple levels of life.The design is evaluated through satisfaction evaluation and SERVQUAL service quality evaluation.The overall perceived quality is higher than the expected quality,and the design meets user needs. |
