Adjustable Bed Support Rail With Pivoting Fall Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobility assistance devices for beds lack effective mechanisms to securely position and prevent individuals with disabilities or infirmities from accidentally falling out of bed, and they often require complex adjustments to fit various bed sizes and configurations.
Innovation Solution
A mobility assistance device comprising a support rail portion, a base portion with adjustable legs, and a securement strap that can be anchored to the bed frame, allowing for telescopic adjustment of the rail length and pivotable design to facilitate easy use and secure positioning, preventing falls by providing support bars that users can grip for balance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing mobility assistance devices are used, then they provide basic support, but they lack effective mechanisms to securely position and prevent individuals from falling out of bed
Solution Approach 1:
The device is divided into distinct functional segments: a base portion with adjustable legs for positioning, a securement strap system for anchoring to the bed frame, and a rail portion with support bars. This segmentation allows each component to perform its specific function effectively while maintaining overall system reliability for fall prevention.
Solution Approach 2:
The securement strap is pre-configured with a buckle mechanism that allows for quick adjustment and securing to the bed frame before the user needs assistance. The adjustable legs are designed to be positioned and locked in place beforehand, ensuring the device is ready for immediate use and provides reliable fall prevention without requiring complex adjustments at the moment of need.
2Adaptability or versatility
If existing mobility assistance devices are used, then they provide support, but they require complex adjustments to fit various bed sizes and configurations
Solution Approach 1:
The device incorporates dynamic adjustment mechanisms including telescopic rail portions that can extend or retract to accommodate different bed lengths, and adjustable legs that can be positioned at various heights and angles. These dynamic features allow the device to adapt to different bed sizes and configurations while maintaining ease of operation through intuitive adjustment mechanisms.
Solution Approach 2:
The device allows for parameter changes in multiple dimensions: the rail portion length can be adjusted via telescopic mechanism, the leg height and angle can be modified, and the securement strap tension can be varied using the buckle system. These parameter adjustments enable the device to fit various bed configurations without requiring complex reconfiguration procedures.
3Reliability
If a securement strap is added to anchor to bed frame, then user security is improved, but device complexity increases
Solution Approach 1:
The securement strap system is designed to be self-adjusting through a buckle mechanism that allows the user or caregiver to easily tighten and secure the strap to the bed frame without requiring additional tools or complex assembly steps. The strap automatically maintains appropriate tension once secured, providing reliable user anchoring while minimizing system complexity.

AI summary
An adjustable mobility assistance device providing support for a user on a bed or similar furniture is disclosed. The mobility assistance device may include a base that can fit under a mattress and a support rail that extends upright relative to the base. The longitudinal dimension of the support rail may be adjustable independent of the base. The support rail may be pivotally coupled to the base so that it can be disposed in an upright configuration or a lowered configuration while the base is under a mattress.
