Pressure ulcers are a type of injury that causes tissue ischemia, a deficiency of nutrition and oxygen to the tissues, and, eventually, tissue necrosis when an area of skin is placed under constant pressure for an extended length of time. With the acceleration of the aging process, the problem of providing care for pressure ulcers for the bedridden elderly becomes increasingly urgent. This study conducts a field survey based on the research status of 221 disabled elderly in 16 communities on 7 typical streets in Beijing, focusing on the problem of pressure ulcer complications caused by bedridden. An automatic inflatable airbag mattress is designed according to anthropometric dimensions of bedridden elderly, pressure ulcer-prone areas, and the decompression standard, so that the airbag mattress can reduce the pressure in its initial shape. To achieve accurate control of the pressure in the pressure-prone areas of an airbag, air pressure control system is proposed which can control airbags individually and link multiple airbags, evaluating the safety of pressure ulcer points based on the data from sensors and making corresponding air pressure changes to reduce the possibility of generating pressure ulcers. The proposed pressure ulcer preventing system will be an efficient healthcare tool for families who had elderly bedridden patients, patients with chronic degenerative disease side effects, and terminal and postsurgical patients, as well as femur fractures, in their homes.

The integration of passenger and cargo transportation has become a new profit development point in the transformation of automotive passenger transport services, and cargo vehicles are a major service touchpoint for the integrated passenger and cargo transport system. This study presents a set of intelligent service touchpoint design principles with intelligent perception, connection, analysis, decision-making, and execution, to innovate the integrated intelligent service system of automobile passenger and cargo transportation, and intelligent self-loading and unloading cargo transport. Based on the field data of cargo transport services of five automobile passenger stations in China, the problems are analyzed and summarized from the aspects of service facilities, content, price, and process, and ultimately form an intelligent service system integrating automobile passenger and cargo transportation. Next, the proposed system is analyzed and compared with five existing intelligent consignment products, and target tasks and requirements of cargo transport vehicles are extracted. The system realizes the usability evaluation of the functional prototype through the combination of open-source hardware, Arduino platform, and mechanical transmission structure, and verifies the availability of the design principles of intelligent service touchpoints.

This paper applies service design thinking and service system constructing methods to innovate the existing service mode of bus terminal. Through the establishment of an intelligent transportation system for luggage consignment and mailing small pieces of luggage, and space-sharing logistics system for passenger luggage compartment, this dissertation provides distributed supply channels for the station convenience stores or restaurants in use of passenger transport network, builds a new on and offline application platform for passenger transport service, establishes a storage space sharing service system for passenger transport, and develops intelligent goods transportation product between the station’s consignment center, the mail office and the luggage compartment. First, this project uses literature, group culture, user research and other research methods to conduct on-the-spot investigations on the bus passenger station service system. After sorting and integrating survey data, it summarizes the service content, problem points and needs of the bus terminal to explore innovative design opportunity points of passenger transport services. Second, this paper evaluates and screens design opportunity points derived from the previous stage to obtain the design orientation of passenger transport innovation service system; then analyzes storage space sharing service system for passenger transport through theoretical methods of service system including the contact layer, system layer, strategic layer and philosophical layer. Finally, using the open source hardware Arduino platform to realize the intelligent self-loading trolley product as the logistics transport module in the service system link, to coordinate the service relationships among various stakeholders in the service link and optimize user experience process and service touch-points.
