Modular Tapered Leg Assembly for Adjustable Support Height
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a leg assembly that can provide adjustable height options for support systems, such as adjustable bed frames, to accommodate various user preferences and ensure stability and comfort.
Innovation Solution
The leg assembly consists of first and second leg members with tapered outer surfaces, allowing for connection to a support frame to provide multiple height settings, with the option to connect individually or in combination, and includes connecting elements for secure attachment, formed from materials like wood and metal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple leg members with different lengths are used to provide adjustable height options, then adaptability is improved, but device complexity increases
Solution Approach 1:
The leg assembly is divided into multiple separate leg members (first leg member, second leg member, third leg member) with different lengths. Each leg member can be independently selected and connected to the support frame, allowing the system to provide adjustable height options without requiring a complex integrated mechanism. This segmentation enables simple addition or removal of leg members to achieve different heights.
Solution Approach 2:
The leg members are designed with universal connecting elements that can attach to the support frame in multiple configurations. The same connecting element structure is used across all leg members, allowing them to serve different height functions while maintaining a unified attachment system. This multi-functionality reduces the need for different connection mechanisms for each height setting.
2Adaptability or versatility
If leg members with different top-to-bottom lengths are used, then adaptability is improved, but manufacturing precision requirements increase
Solution Approach 1:
Instead of manufacturing a single complex adjustable leg mechanism, the solution segments the height adjustment function into separate leg members with fixed, predetermined lengths. Each leg member's length is precisely manufactured independently, and the overall height precision is achieved through the selection and combination of these pre-manufactured segments, reducing the complexity of precision requirements for any single component.

AI summary
A leg assembly includes a first leg member and second leg member each having side-to-side width that is greater at the top end than the bottom end and a tapered outer surface. The second leg member has top-to-bottom length different than the top-to-bottom length of the first leg member. The leg members are adapted to connect individually or in combination to a support system such that at least three leg heights are selectably provided. The side-to-side width of the top end of the second leg member is approximately equal to the side-to-side width of the bottom end of the first leg member such that when the top end of the second leg members is connected to the bottom end of the first leg member, the combined leg members have a generally continuously tapered outer surface.
