Nested Wedge Table Leveler for Portable Furniture Stabilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for stabilizing uneven furniture, such as shims and adjustable feet, are not portable or reusable for public use, leaving rocking tables and chairs unaddressed.
Innovation Solution
A pair of centrally rotatable wedges, designed to ISO/IEC 7810 ID-1 dimensions, that can be affixed to form a rectangular prism for stabilizing furniture on uneven surfaces, with optional ridges for increased friction and a locking mechanism for stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If shims made from plastic or rubber are used to stabilize furniture, then the furniture can be leveled, but the shims are not portable or reusable for public use
Solution Approach 1:
The two wedge-shaped members are designed to nest within each other when not in use, forming a compact package that fits in a pocket or small bag. This nesting configuration enables portability while maintaining the full stabilization capability when deployed.
Solution Approach 2:
The stabilization device is divided into two separate wedge-shaped members that can be independently positioned under different furniture legs. This segmentation allows each wedge to be used separately or together, providing flexibility for various stabilization scenarios and improving portability.
2Reliability
If adjustable feet are used to stabilize furniture, then the furniture can be leveled, but the adjustable feet are not designed to be carried for public, repeatable use
Solution Approach 1:
The adjustable feet are replaced with wedge-shaped members that nest within each other, creating a compact portable unit that can be easily carried for public use while maintaining adjustment capability through different positioning configurations.
Solution Approach 2:
The wedge-shaped members are designed with universal applicability to work with various furniture types (tables, chairs, desks) and different instability scenarios, replacing specialized adjustable feet with a multi-functional solution that is both portable and effective.
3Reliability
If two wedge-shaped members are used to stabilize furniture, then the stabilization is effective, but the device may be bulky for portability
Solution Approach 1:
The two wedge-shaped members are designed to nest within each other when not in use, significantly reducing the overall volume of the device for transport while maintaining the full stabilization capability when deployed. This nesting configuration allows the device to fit in a pocket or small bag.
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
Provides portable and reusable stabilization for tables, chairs, and other furniture by preventing rocking, ensuring ease of transport and versatility in various settings.
Implementation Method 1
the wedges are ridged, 14, on the exterior surface to allow for higher friction with the floor and the furniture item to be stabilized
