Mobile Stage Telescopic Columns Cable Pull Drive
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile stages require significant force to fold and set up, making them difficult for untrained personnel to assemble safely and efficiently, and often exceed weight or size limits, leading to potential driving bans on Sundays or public holidays.
Innovation Solution
The use of telescopic columns with a cable pull connected to a piston-cylinder drive, allowing for simultaneous extension of all columns and enabling easy, time-saving, and energy-efficient assembly, along with a roof structure that can be arched for increased room height and a foldable floor to maintain size compliance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual folding of roof and floor elements is used, then the stage can be assembled without special equipment, but it requires not inconsiderable force and is difficult for untrained personnel
Solution Approach 1:
The patent replaces manual mechanical folding with a hydraulic lifting system. A hydraulic jack (Hydraulikheben) automatically lifts the roof structure and floor elements into their final positions, eliminating the need for manual force application and making assembly accessible to untrained personnel.
Solution Approach 2:
The patent employs a hydraulic support system (Hydraulikstütze) with telescopic columns to provide automated lifting force. The hydraulic mechanism generates the necessary force to raise the heavy roof structure without requiring manual effort, directly resolving the contradiction between ease of operation and force requirement.
2Area of stationary object
If the stage is designed with full roof coverage, then it provides complete protection, but it exceeds the maximum permissible width of 2.55 m
Solution Approach 1:
The patent uses laterally displaceable outer traverses (seitenverschiebbare Außenstrecken) that can be adjusted during operation. These traverses can be extended to provide full roof coverage when needed and retracted or positioned to maintain compliance with width regulations during transportation, enabling the structure to adapt between protective coverage and regulatory compliance.
Solution Approach 2:
The roof structure is divided into modular components including inner and outer traverses that can be independently positioned. This segmentation allows the outer traverses to be laterally displaced to achieve full coverage while maintaining overall width compliance through coordinated positioning of separate structural elements.
3Productivity
If telescopic columns with cable pull are used, then all columns extend simultaneously saving time and energy, but the device complexity increases
Solution Approach 1:
The patent connects all telescopic columns through a common cable pull system (Seilzugverbindung) that is actuated by a single piston-cylinder drive. This merging of multiple independent lifting mechanisms into one coordinated system enables simultaneous extension of all columns, achieving fast assembly while managing complexity through centralized control.
Solution Approach 2:
The cable pull system acts as an intermediary mechanism that translates the action of a single piston-cylinder drive into coordinated movement of multiple telescopic columns. This intermediary approach allows simultaneous column extension without requiring multiple independent actuators, balancing productivity improvement with acceptable 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
Facilitates simple, quick, and energy-efficient setup of the mobile stage, reducing assembly force requirements and ensuring compliance with size and weight regulations, allowing for trouble-free transportation without special permits or driving bans.
Implementation Method 1
especially if such telescopic columns work with hydraulic support
Implementation Method 2
The cable pull is tightened by the piston-cylinder drive, which can be driven by an electric pump, whereby the connection of the four rams of the four columns with a cable pull ensures that all rams are extended in the same way

AI summary
Mobile stage (1) comprises a roof structure (10) having outer parallel traverses received by support units (4). Preferred Features: The support units each have two telescopic columns fixed at a distance from each other on the chassis (2). The columns each have a hydraulic telescopic stamp. The stamps of both support units are connected by a cable pull which is joined to a piston cylinder drive.
