Support Column Fixture With Friction Clamping for Variable Diameters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing attachment devices for support columns in furniture are costly to produce and lack flexibility in accommodating varying support column diameters, leading to instability and difficulty in adjusting the attachment position.
Innovation Solution
A sheet metal-based attachment device with laterally protruding receiving sections, a clamping body, and a support surface at varying distances from the support column, allowing for frictional clamping and adjustable holding forces, along with a reduced-diameter section for rotational symmetry and a screw for secure fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional attachment devices with complex clamping mechanisms are used, then reliable fixation on support columns is achieved, but production cost increases significantly
Solution Approach 1:
The attachment device is divided into two separate receiving sections instead of a single complex clamping mechanism. Each receiving section independently receives the support column, simplifying manufacturing while maintaining reliable fixation through the distributed clamping arrangement
Solution Approach 2:
The base body is made from sheet metal that can be stamped and bent, replacing expensive traditional clamping mechanisms. This cost-effective approach achieves reliable fixation without complex components, suitable for mass production
2Stability of the object's composition
If fixed clamping mechanisms are used, then stable attachment is achieved, but adjustability of attachment position is lost
Solution Approach 1:
The clamping mechanism transitions from a fixed state to a dynamic adjustable state. The pressing device can be moved along the support column to different positions, and the clamping force can be adjusted, allowing the attachment device to adapt to various installation requirements while maintaining stability at each position
3Device complexity
If uniform clamping force is applied, then simple mechanism design is achieved, but risk of overloading and damage increases
Solution Approach 1:
The pressing device features a support surface with varying distances from the support column - closer in some areas and farther in others. This creates non-uniform local clamping forces that adapt to the specific geometry and load requirements at different positions, preventing overloading while maintaining overall stability
4Adaptability or versatility
If multiple separate components are used, then adaptability to different support column diameters is achieved, but device complexity and production cost increase
Solution Approach 1:
The base body with its two receiving sections serves multiple functions: it provides structural support, guides the support column through the receiving openings, and works with the pressing device to achieve clamping. This multi-functional design adapts to different support column diameters without requiring separate components for each function
Applied Scientific Principles

Implementation Method 1
the clamping body with the supporting device being able to be pressed against the support column inserted through both receiving openings in such a way that the supporting column on the attachment device is between the receiving sections and the clamping body is clamped and fixed by friction
