The objective of this project is to design and manufacture a bed that provides increased safety and convenience to patients needing physical assistance and their caregivers, specifically catering to special needs patients. The bed is designed to have variable height between 0” and 30” from the bottom of the mattress to the ground, allowing the patient to get into bed with minimal physical assistance from the caregiver. The design process for this product was organized in three subsystems: lifting mechanism, escape prevention, and frame. The lifting mechanism is designed to accommodate the bed’s variable height, as well as support the weight of the mattress and patient up to 800 lb. The escape prevention system prevents the patient from escaping or accidentally falling out of bed. Finally, the frame provides structural support for the entire system, and is the framework for the other subsystems. This report discusses the planning, design, analysis, and manufacturing of the bed.
