Holding Stand Structure With Load-Triggered Floor Force Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing holding stands for supports, such as ceiling supports, face challenges in efficiently managing force loading, leading to complex constructions and increased mass, which complicates their use and positioning.
Innovation Solution
A holding stand with at least three stand legs, each having a first and second arm connected at an acute angle, where the put up-receiving device's floor side lies in the stand leg put up plane only when force loading exceeds a specific threshold, allowing forces to be directed into the floor, reducing mechanical loading and enabling a simpler, lighter construction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the holding stand is designed to securely hold supports, then stability and strength are improved, but device complexity and mass increase
Solution Approach 1:
The holding stand employs dynamic behavior where the floor side of the put up-receiving device selectively contacts the floor based on force loading thresholds. When force exceeds the threshold during support deployment, the floor side contacts the floor to conduct away forces; when force is below the threshold during positioning, the floor side remains spaced to allow simple movement. This dynamic adaptation resolves the contradiction by providing stability only when needed.
Solution Approach 2:
The invention changes the physical state and position of the floor side relative to the floor based on force loading parameters. The floor side transitions between two states: spaced from the floor during low-force positioning operations, and in contact with the floor during high-force deployment operations. This parameter-based state change allows the system to achieve both simplicity and stability as needed.
2Strength
If the holding stand is designed to securely hold supports, then strength and stability are improved, but mass increases
Solution Approach 1:
The holding stand utilizes the floor itself as a force-bearing element through the floor side of the put up-receiving device. When force loading exceeds the threshold, the floor side contacts the floor, allowing the floor to bear the load and conduct away forces from the holding stand structure. This self-service approach allows the lightweight stand to achieve high strength by leveraging the external floor surface.
3Force
If the floor side constantly contacts the floor, then force conduction is improved, but positioning simplicity and ease of operation deteriorate
Solution Approach 1:
The design prevents premature or unnecessary contact between the floor side and the floor by maintaining a spaced relationship during low-force positioning operations. This preliminary anti-action avoids unwanted force conduction and friction that would complicate positioning. Only when force loading exceeds the threshold does contact occur, ensuring force conduction happens only when beneficial.

AI summary
A holding stand for a support is provided, comprising a put up-receiving device for the support which has a support put up face, and at least three stand legs. Each of the stand legs has a first arm and a second arm which are connected to one another. The second arm is oriented at an acute angle to the first arm. The put up-receiving device is arranged on the first arms of the stand legs. In a holding state of the holding stand, the stand legs define a stand leg put up plane for the holding stand. A floor side of the put up-receiving device facing away from the support put up face lies in the put up plane, at least when a force loading of the put up-receiving device exceeds a specific threshold value or threshold value range in the direction of the put up plane.
