Removable Table Leg with Tool-Free Clamp and Threaded Locking Rod
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing removable table legs are costly, difficult to manufacture and assemble, and lack aesthetic appeal, failing to provide a simple tool-free installation process.
Innovation Solution
A removable table leg design featuring an elongate leg with a locking rod, annular knob, and L-shaped bracket, allowing for tool-free adjustment and secure attachment to a table surface without specialized skills, with a clamp mechanism that includes top and bottom fixed plates and a locking rod extending through internally threaded holes for easy assembly and disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single integral construction with complex clamping mechanism is used, then the table leg provides secure attachment, but the manufacturing cost and assembly difficulty increase significantly
Solution Approach 1:
The table leg is divided into separate modular components: an elongate leg portion, a clamp portion with fixed plates, and a locking mechanism with rod and knob. These segments can be manufactured independently using simple processes and then assembled together, reducing manufacturing complexity and cost while maintaining secure attachment capability
Solution Approach 2:
The clamp portion combines multiple functions into a single integrated component: the fixed plates provide clamping surfaces, the rod provides the locking mechanism, and the knob provides adjustment capability. This merging simplifies the overall structure compared to complex integral constructions while ensuring secure attachment
2Strength
If a complex integral construction is used, then the table leg provides structural strength, but the assembly process requires tools and specialized skills
Solution Approach 1:
The leg assembly is segmented into pre-manufactured components that can be assembled without tools. The clamp portion with fixed plates and the locking mechanism with rod and knob are separate pieces that fit together through simple insertion and manual tightening, eliminating the need for specialized assembly skills
Solution Approach 2:
The locking mechanism is designed to be self-contained and self-assembling. The rod inserts through the fixed plates and is secured by manual tightening of the knob, creating a self-service assembly process that requires no external tools or specialized knowledge while maintaining structural integrity
3Adaptability or versatility
If a traditional removable table leg design is used, then the leg can be detached, but the appearance and aesthetics are compromised
Solution Approach 1:
The clamp portion is designed to blend aesthetically with the elongate leg portion, creating a unified appearance when attached. The fixed plates and locking mechanism are configured to be visually harmonious, making the removable leg appear as an integrated part of the furniture piece while retaining detachability

AI summary
A table leg has an elongate leg having, a locking rod, and an annular knob having an internally threaded hole threadedly receiving the locking rod therethrough. Top and bottom fixed plates are provided for sandwiching the annular knob therebetween. An L-shaped bracket having a vertical portion that extends from a bottom edge to a corner, and a horizontal portion that extends from the corner to a terminal edge, is attached to the top and bottom fixed plates for clamping the table between the horizontal portion and the locking rod.
