Portable Mobility Support Structure for Independent Floor Transitions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobility aids for individuals with physical limitations are stigmatizing, require multiple caretakers, and do not empower users to engage in activities that involve getting down to or up from the floor independently, leading to reduced mobility and increased fear of falling.
Innovation Solution
A portable, free-standing support structure with vertically spaced handholds that allows users to safely and confidently transition between standing and lying, sitting, or kneeling positions, encouraging proper muscle use and reducing the need for caretakers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional mobility devices are used to assist users in getting up from the floor, then users can receive physical assistance, but the devices are stigmatizing and require multiple caretakers, reducing user independence
Solution Approach 1:
The mobility device is designed to be used independently by the user without requiring multiple caretakers. The device includes a base structure with handholds and support elements that enable the user to autonomously transition between sitting/lying and standing positions, eliminating the need for complex multi-person assistance systems
Solution Approach 2:
The device is divided into functional segments including a base portion, vertical support members, handholds, and safety elements. This segmentation allows each component to perform its specific function independently, enabling the user to navigate the transition process alone without requiring coordinated assistance from multiple people
2Adaptability or versatility
If existing mobility aids are used, then users can receive assistance, but the devices do not empower users to engage in activities involving getting down to or up from the floor independently
Solution Approach 1:
The mobility device serves multiple functions: it provides structural support during transitions, offers handholds for grasping, includes safety elements for fall prevention, and can be used for both ascending and descending movements. This multi-functionality enables users to independently engage in various floor activities without requiring specialized equipment for each function
Solution Approach 2:
The device is designed with pre-positioned handholds and support elements that are ready for immediate use. The base structure and vertical members are pre-configured to provide stable support during the transition process, allowing users to confidently engage in floor activities without needing to assemble or adjust complex support systems
3Reliability
If users avoid getting down on the ground due to fear of falling, then safety is maintained, but mobility and quality of life are reduced
Solution Approach 1:
The device incorporates safety elements such as a wide base structure for stability, handholds positioned at appropriate heights, and support members designed to prevent sudden falls. These safety features are built into the device beforehand to cushion and prevent the harmful effects of falling during floor transitions, allowing users to move confidently without fear
Solution Approach 2:
The mobility device acts as an intermediary between the user and the floor. It provides a structured transition pathway with handholds and support elements that mediate the movement process, reducing the fear of falling by providing controlled support while enabling the user to independently navigate between sitting/lying and standing positions
4Reliability
If mobility devices are made sturdy and safe, then user confidence is improved, but the devices may be large and expensive
Solution Approach 1:
The device applies structural strength and safety features locally where needed rather than throughout the entire structure. The base portion and vertical support members are designed with appropriate rigidity and stability for their specific functions, while avoiding unnecessary complexity in areas where less strength is required, thereby reducing overall size and cost

AI summary
A mobility device designed to extend the usable field of movement for people with physical limitations by allowing them to descend to the ground and ascend to an upright position with ease. A user may bring the device within their vicinity, grab onto the articulating handles and safely reach the ground to engage in a ground activity. When the ground activity is completed, the user simply grabs onto the sloping handholds and ascends step-by-step until they have made their way to a standing position. The device is portable and can be stowed around the home. It is likely to be close to the user at all times, thus it is a safe means of ensuring support when a caretaker is not present.
