Research On Scenario-based Design Of Shared Wheelchairs

The main contradiction in Chinese society has shifted from the contradiction between the people’s growing material and cultural needs and the backwardness of social production to the contradiction between the growing demand for a better life and the unbalanced and inadequate development.While people’s requirements for quality of life are increasing,the problem of convenient transportation for people with disabilities remains a major social concern that needs to be urgently addressed.As an important tool for the mobility of people with disabilities,shared wheelchairs need to be designed and innovated in terms of usability,safety,and comfort to better meet the needs of hospital settings.This project takes scene theory as a guide and focuses on the problems of inconvenient borrowing and returning,discomfort from long sitting,and difficulty in pushing of existing shared wheelchairs in hospitals.It explores the feasibility of scene theory in the design of shared wheelchairs,studies the design methods and processes of shared wheelchairs based on scene theory,and promotes the innovation and development of shared wheelchair products,providing a safer and more convenient medical experience for people with disabilities.Chapter One provides a literature review of domestic and foreign research on shared wheelchairs.Western countries such as the United States and Europe have already integrated shared wheelchairs as an indispensable part of the urban transportation system.The theoretical research in these countries mainly focuses on technological innovation and care for vulnerable groups related to shared wheelchair design.However,research in China has focused more on the commercial value,application effects,and specific functions of shared wheelchairs,with less exploration of corresponding functional design in specific scenarios.Chapter Two introduces the concept of scenario theory and explains its three stages: the objective scenario for analyzing user needs,the target scenario for product interaction design,and the actual application scenario for scenario verification and evaluation.The chapter also discusses dynamic thinking,decomposition thinking,and primary and secondary thinking based on user scenarios.Furthermore,the chapter analyzes the usage scenario of shared wheelchairs,determines the research goal of designing shared wheelchairs for hospitals,and constructs five elements of user,environment,behavior,tool,and goal for hospital scenarios.Chapter Three analyzes the objective scenario,including the composition of shared wheelchairs,usage environment,placement location,and usage process based on the hospital scenario and its user,environment,behavior,tool,and goal elements.The Kano model is used to identify three types of user needs: basic needs,expected needs,and attractive needs for hospital shared wheelchairs.Chapter Four constructs the target scenario and functional architecture of hospital shared wheelchairs based on user needs in the objective scenario.Design strategies at three levels,including ergonomics,hospital scenarios,and digital technology,are proposed to improve comfort,enhance safety,and optimize interaction experience.Chapter Five describes the design practice of hospital shared wheelchairs,which were simulated in actual hospital scenarios.User surveys were conducted with three different user groups,including people with disabilities,caregivers,and medical operation staff.The results showed that the design of automatic positioning,adjustable seats,navigation,and other features fell within the user satisfaction range.The effectiveness of scenario theory in the design process of medical products,represented by shared wheelchairs,was demonstrated,providing a model and reference for other product design processes based on scenario analysis.
