Modular Bed Frame Leg Assembly for Selectable Support Heights
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for an adjustable bed system that provides concealed assembly and modular leg solutions to accommodate various user preferences and mobility needs, particularly for users with limited mobility due to health conditions or injuries, requiring adjustable bed configurations that can control multiple devices from the bed without leaving it.
Innovation Solution
The adjustable bed system incorporates a support frame with modular leg assemblies and a control system that allows users to adjust bed positions and control devices such as audio, video, and lighting from the bed, using a remote control, and features a skeleton structure that supports the mattress and actuators, with safety features to prevent crushing objects underneath.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed leg assembly is used, then the manufacturing cost is reduced, but the adaptability to different user needs and mobility conditions deteriorates
Solution Approach 1:
The leg assembly is divided into multiple detachable components including different length leg members (first leg member, second leg member), connecting elements, and mounting options. This segmentation allows users to assemble custom configurations (single leg, double leg, varying heights) to suit different mobility needs and bed placement scenarios without requiring a completely different assembly for each case.
Solution Approach 2:
The connecting elements are designed with universal threading patterns that can attach various leg members to different frame positions. The same connecting element can join the first leg member or second leg member to the frame, and can also connect multiple leg members together, creating a multi-functional component that serves multiple assembly configurations.
2Ease of operation
If multiple leg length options are provided, then the ease of operation for users with limited mobility is improved, but the device complexity increases
Solution Approach 1:
The leg assembly transitions from a static, fixed-length design to a dynamic, reconfigurable system where leg members can be detached, repositioned, and reattached. This allows the bed frame to adapt its configuration based on user needs and environmental conditions, providing ease of operation for users with limited mobility who can have the bed positioned optimally.
Solution Approach 2:
The first leg member and second leg member can be connected in series through connecting elements, creating a nested or stacked configuration where one leg member extends the length of another. This nesting approach allows for extended reach or adjusted heights without requiring entirely separate structural components.
3Adaptability or versatility
If modular leg assemblies are used, then the adaptability to different configurations is improved, but the manufacturing cost increases
Solution Approach 1:
The design varies the length parameter of leg members (first leg member with length L1, second leg member with length L2) while maintaining the same basic structural form and connecting interface. This parameter-based differentiation allows for configuration flexibility without requiring fundamentally different manufacturing processes for each leg type, as both can be produced using similar techniques with adjusted dimensions.

AI summary
A support system includes a support frame and at least one modular leg assembly mounted to and supporting the support frame. The leg assembly includes a first leg member and a second leg member. The second leg member has a top-to-bottom length that is greater than the top-to-bottom length of the first leg member. The first and second leg members are connected individually or in combination to the support frame such that at least three leg heights are selectably provided. The leg members may each have a threaded connecting element extending therefrom for connecting the leg member to another leg member or to the support frame. The support system may be a mattress support frame. The at least one modular leg assembly may be a plurality of modular leg assemblies.
