Adjustable Bed Support Rail for Reversible Side Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobility assistance devices lack versatility and ease of use, particularly in adapting to different bed orientations and sizes, which can lead to assembly errors and inadequate support for individuals with limited mobility.
Innovation Solution
The mobility assistance device features a support rail with an adjustable end that can be lengthened or shortened, reversibly coupled to base legs, allowing orientation adjustment for either side of a bed, and includes a securement strap for stability, along with a lock mechanism for customizable length and a compact storage configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the support rail has a fixed length, then the device structure is simple, but it cannot adapt to different bed sizes and orientations
Solution Approach 1:
The support rail is divided into multiple sections that can be extended or reconfigured. The rail includes a first section and a second section that can be positioned at different orientations (e.g., perpendicular or parallel to the bed), allowing adaptation to various bed sizes without requiring multiple different device models.
Solution Approach 2:
The support rail incorporates adjustable and movable components that allow dynamic reconfiguration. The rail sections can be extended, retracted, or repositioned to match different bed dimensions and orientations, transforming a static structure into a dynamic one that adapts to user needs.
2Ease of operation
If the device is designed for specific bed orientations only, then the assembly is simple, but it causes assembly errors when used with beds of varying orientations
Solution Approach 1:
The mobility assistance device is designed with universal mounting capabilities that work with beds of any orientation. The base can be attached to the bed frame in different configurations, and the support rail can be oriented perpendicular or parallel to the bed, eliminating assembly errors by providing a universal solution rather than orientation-specific designs.
Solution Approach 2:
The device incorporates asymmetric mounting mechanisms that automatically adapt to different bed orientations. The mounting interface is designed to accommodate various configurations through asymmetric features that guide correct assembly regardless of the bed's orientation, preventing assembly errors.
3Adaptability or versatility
If the support rail is fixed and non-adjustable, then the device is easier to manufacture, but it provides inadequate support for individuals with limited mobility who need customizable support
Solution Approach 1:
The support rail incorporates adjustable mechanisms that allow it to be extended or retracted to different lengths. This dynamic capability enables customization of the support length to match individual user needs while maintaining a relatively simple manufacturing process by using telescopic or segmented rail designs.
