Telescopic Mast With Self-Locking Arm for Roller Shutter Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Installing building elements like roller shutters requires two installers due to their weight and bulk, making it difficult for a single person to handle and assemble safely and efficiently.
Innovation Solution
A device with a telescopic mast and articulated arm, allowing a single person to support and position building elements horizontally, featuring a self-locking mechanism for precise height adjustment and compact storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single person installs building elements, then ease of operation is improved, but the ability to safely handle heavy elements deteriorates
Solution Approach 1:
The device acts as an intermediary tool between the installer and the heavy building element. The telescopic mast provides a stable support structure that can bear the weight of the element, while the articulated arm with support surface provides a controlled interface for positioning. This mediator device enables a single person to safely handle elements that would otherwise require two people, as the device bears the load rather than relying on human strength alone.
Solution Approach 2:
The device is divided into functional segments: a telescopic mast for vertical support and height adjustment, an articulated arm for horizontal positioning, and a support surface for carrying the element. This segmentation allows each component to be optimized for its specific function while working together to provide safe and easy operation for single-person installation.
2Ease of operation
If the device is made compact for transport, then ease of transport is improved, but the height adjustment capability deteriorates
Solution Approach 1:
The mast is designed as a telescopic structure that can dynamically adjust its length. When not in use, the mast segments are retracted to create a compact, space-saving configuration that is easy to transport and store. When needed, the mast extends to provide the necessary height adjustment capability for installing building elements at various heights. This dynamic transformation allows the device to optimize between compact transport and functional height adjustment.
3Device complexity
If the arm is fixed in position, then device complexity is reduced, but adaptability deteriorates
Solution Approach 1:
The arm is designed with articulation points that allow it to move between a stowed position (parallel to the mast) and a support position (perpendicular to the mast). This dynamic capability enables the arm to adapt to different installation scenarios and height requirements while maintaining relatively simple device complexity through the use of basic articulation mechanisms rather than complex actuation systems.
Solution Approach 2:
The arm is segmented into sections that can be independently positioned and locked. This segmentation allows the arm to be adjusted to different angles and positions along the mast while maintaining structural simplicity. Each segment can be locked in place using basic locking mechanisms, providing adaptability without requiring complex control systems.
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
Enables a single person to safely and easily install heavy building elements by providing stable support and precise height adjustment, minimizing bulk and effort, and allowing easy transport and operation.
Implementation Method 1
The locking system comprises a flexible locking part and a return spring applied against the locking part, the locking part includes a through hole for the passage of the mast and is connected to the interface part by being inclined (or braced) relative to the mast and wedged against the mast in the rest position of the return spring
Implementation Method 2
The telescopic mast and its right-angled arm which is movable in translation along the mast

AI summary
Device (1) for assisting in the temporary support and/or assembly of a building element, comprising a telescopic mast (10), characterized in that it further comprises at least one arm (3) with a support function, the arm (3) being articulated to adopt either a position at right angles to the mast (10), called the support position, or a position parallel to the mast (10), called the stowed position, and the arm (3) being capable of being movable in translation along the mast and being locked in its support position. Such a device, in particular used in pairs, allows a single installer to mount a roller shutter completely independently.
