Stand for putting up post- or stick-type parts with a reinforced clamping holder
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stands for mounting mast or rod-shaped parts, such as Christmas trees, lack stability and are costly to manufacture, as they require robust materials for the wall structure and clamping devices.
Innovation Solution
A stand design featuring a stabilizing component made of a stronger material than the wall structure, with a tensioning device and flexible force transmission system that absorbs counterforces, allowing the wall structure to be made of thinner, more cost-effective material, and a guide device that immovably connects the stabilizing component to the base plate, enhancing stability and simplifying production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the wall structure is made of robust material to ensure stability, then the stability is improved, but the manufacturing cost increases
Solution Approach 1:
The stand is divided into two functional parts: a wall structure made of cost-effective material and a stabilizing component made of stronger material. This segmentation allows each part to be optimized for its specific function while using appropriate materials, reducing overall manufacturing cost while maintaining stability.
Solution Approach 2:
Instead of making the entire wall structure from robust material, the patent applies the stronger stabilizing component only at the critical location where clamping forces are transmitted to the base plate. This local reinforcement maintains stability while minimizing material costs.
2Ease of manufacture
If the wall structure is made of thinner, cost-effective material, then the manufacturing cost decreases, but the stability deteriorates
Solution Approach 1:
The stabilizing component acts as an intermediary element between the holding elements and the base plate. It receives and transmits the clamping forces directly to the base plate, bypassing the need for the wall structure to bear these forces, thus allowing the wall structure to be made of thinner, cheaper material.
Solution Approach 2:
The stabilizing component is extracted as a separate element from the wall structure. This allows the wall structure to be simplified and made from less robust material, while the stabilizing component independently handles the stability requirement through its stronger material and direct connection to the base plate.
3Stability of the object's composition
If a stabilizing component is added to improve stability, then the stability is improved, but the device complexity increases
Solution Approach 1:
The stabilizing component is designed to be integrated with the base plate through the guide device, forming a unified stable base structure. This merging approach reduces the number of separate components and simplifies assembly, offsetting the initial addition of the stabilizing component.
Solution Approach 2:
The stabilizing component serves multiple functions: it provides structural stability, guides the holding elements, and transmits clamping forces to the base plate. This multi-functionality reduces the need for separate components, thereby limiting the increase in device complexity.
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 stand achieves increased stability and reduced material costs by transmitting clamping forces through a stronger stabilizing component, enabling the use of less robust materials for the wall structure while maintaining effective clamping and preventing pivoting of holding elements.
Implementation Method 1
a force transmission device which is pulled in a pulling direction towards the tensioning device by transferring the tensioning device from an unlocking position in the direction of a securing position
Implementation Method 2
the clamping device is in direct contact with the stabilizing component. The reaction force, which corresponds to the clamping force of the clamping device, is transmitted to the base plate of the stand via the stabilizing component
