Adjustable Bed Step with Back Support for Safe Ingress
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Individuals with physical or mobility disabilities face challenges in safely getting in and out of beds due to lack of effective assistance devices that provide stable support and prevent accidents.
Innovation Solution
A mobility assistance device featuring a step platform with adjustable height, handle bars, and support legs, including a back support bar to prevent movement and entrapment, designed to be placed adjacent the bed for safe ingress and egress, with features like non-slip surfaces and adjustable components for user comfort and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a bed step device is provided to assist individuals with mobility disabilities, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The bed step device is divided into distinct functional segments: a step platform for foot placement, handle bars for upper body support, support legs for stability, and a back support bar for positional control. This segmentation allows each component to perform its specific function independently, improving overall ease of operation while managing complexity through modular design
Solution Approach 2:
The bed step device acts as an intermediary between the bed and the floor, providing a transitional platform that bridges the height difference. This intermediary structure enables safe weight transfer and positional transition for individuals with mobility disabilities without requiring direct interaction with the bed frame or floor
2Reliability
If the device is designed with stable support features, then reliability is improved, but device complexity increases
Solution Approach 1:
Different parts of the device have specialized local properties optimized for their specific functions: the support legs have non-slip feet for floor adhesion, the step platform has a non-slip surface for foot grip, the handle bars provide ergonomic grip surfaces, and the back support bar has a specific geometry for engaging with the bed. This local quality differentiation enhances reliability without requiring complex overall structure
Solution Approach 2:
The device incorporates preventive safety features before accidents can occur: non-slip surfaces on the step platform and support legs prevent slipping before it happens, the back support bar prevents the device from moving under the bed in advance, and the handle bars provide ready-available support for maintaining balance throughout the transition process
3Adaptability or versatility
If adjustable components are added for user comfort, then adaptability is improved, but device complexity increases
Solution Approach 1:
The bed step device incorporates adjustable support legs that can be modified in length to accommodate different bed heights and user requirements. This dynamic adjustability allows the device to adapt to various users and sleeping arrangements while maintaining a relatively simple overall structure through straightforward mechanical adjustment mechanisms

AI summary
Mobility assistance devices to facilitate egress from and ingress into a bed are disclosed. The devices include a step platform coupled to a handle bar and a back support bar. The step platform is supported by support legs. A height of the handle is adjustable relative to the step platform. A height of the step platform relative to the floor is adjustable by adjusting a length of the support legs extending below the step platform. The handle bar includes a horizontal portion that extends partially toward a plane extending upward from the back support bar.
