Furniture leg attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing furniture leg attachments fail to effectively level and stabilize furniture on uneven outdoor surfaces, as they either lack adjustability or do not prevent sliding down slopes, with common solutions being unreliable or not widely available.
Innovation Solution
A furniture leg attachment featuring a leg-receiving tube, ball-and-socket joint, incremental height-adjustment mechanism, and ground-gripping protrusions that allow for adjustable leg positioning and enhanced surface contact to prevent sliding, utilizing a textured surface and peg system for stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a solid flat object (brick or rock) is placed under a short leg to level furniture, then the furniture body is leveled and items do not slide off, but the support is unreliable and easy to knock away
Solution Approach 1:
The furniture leg is segmented into an adjustable extension component that can be independently positioned. The leg extension includes a telescopic mechanism with multiple segments that can be extended or retracted to achieve precise length adjustment, allowing the leg to reach the ground on uneven surfaces without requiring external objects like bricks or rocks.
Solution Approach 2:
The leg extension incorporates a dynamic adjustment mechanism that allows the user to modify the leg length in real-time. The telescopic design with lockable segments enables the leg to adapt to different ground conditions, providing reliable support that maintains both leveling stability and resistance to displacement.
2Stability of the object's composition
If length-adjustable legs are used to level furniture, then furniture can be leveled on uneven surfaces, but few items provide this feature making it unavailable
Solution Approach 1:
The leg extension is designed as a separate, attachable component that can be added to existing furniture legs. This segmentation allows the adjustable length feature to be applied to various furniture types without requiring complete leg replacement, increasing market availability and adaptability.
Solution Approach 2:
The leg extension mechanism is designed with universal compatibility to fit multiple furniture types and ground conditions. The adjustable design serves multiple functions: leveling on slopes, compensating for uneven surfaces, and providing additional height adjustment, making it a versatile solution widely applicable to different furniture pieces.
3Reliability
If a textured surface is added to prevent sliding, then the attachment prevents sliding down angled slopes, but the surface texture increases complexity
Solution Approach 1:
The textured surface is applied only to the foot of the leg extension where ground contact occurs, rather than the entire component. This localized application provides slip prevention functionality while minimizing the increase in overall device complexity.
Solution Approach 2:
The foot surface incorporates friction parameter changes through texturing or material selection, increasing the coefficient of friction at the ground-contact interface. This parameter modification enhances grip and prevents slipping without requiring complex mechanical structures.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively stabilizes furniture on uneven surfaces by allowing adjustable leg positioning and preventing sliding, ensuring stability and preventing furniture from shifting or sliding on slopes.
Implementation Method 1
The present invention utilizes a textured surface connected to a sleeve by a ball-and-socket joint to allow chair and table legs to connect and adjust to various surface slopes.
Implementation Method 2
The textured surface further prevents the present invention from sliding down angled slopes and surfaces.

AI summary
The furniture leg attachment is an apparatus that is used to stabilize an uneven chair, table, or other piece of furniture. The apparatus is also configured to prevent sliding on rough or uneven surfaces, such as may be encountered during outdoor furniture use. The apparatus comprises a leg-receiving tube, a foot, a ball-and-socket joint, an incremental height-adjustment mechanism, and a plurality of ground-gripping protrusions. The leg-receiving tube connects to the foot by the ball-and-socket joint, which allows the foot to rotate and adjust relative to the surface that the table or chair is positioned upon. The incremental height-adjustment mechanism is part of the leg-receiving tube that allows the user to modify the height of the foot and the table or chair leg above the ground. The plurality of ground-gripping protrusions extends from the foot to grasp the surface that the present invention is upon.
