Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual stapling of membrane elements to supports is time-consuming and costly, requiring substantial quality control efforts.
Innovation Solution
An automatic station comprising a fixing sub-station, a jig, an articulated arm, and a pneumatic stapler, with pads and a control unit to precisely position and tension the membrane element before stapling, allowing for automated and efficient attachment to a support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual stapling is performed by a technician, then flexibility and adaptability are maintained, but implementation time increases and quality control costs increase
Solution Approach 1:
The automatic station is divided into distinct functional modules: a fixing sub-station for positioning the support, a jig for holding the membrane element, an articulated arm for positioning, and a stapler for the actual stapling operation. This segmentation allows each component to be optimized independently while working together to achieve automated stapling, resolving the contradiction between productivity improvement and system complexity.
Solution Approach 2:
The articulated arm acts as an intermediary between the fixed stapler and the workpiece, enabling precise positioning and movement of the stapler to different locations on the membrane element. This intermediary mechanism allows automated stapling across large surfaces without requiring the entire system to be mobile, balancing automation capability with structural simplicity.
2Manufacturing precision
If manual stapling is performed, then quality control can be visually inspected, but substantial quality control costs and time are required
Solution Approach 1:
The fixing sub-station and jig are designed with precise positioning mechanisms that provide feedback control for locating the support and membrane element. The articulated arm system enables programmed movement to predetermined stapling locations, ensuring consistent positioning accuracy. This built-in precision reduces the need for post-stapling quality control inspection, eliminating time loss while maintaining high manufacturing precision.
3Manufacturing precision
If the membrane element is tensioned during stapling, then stapling quality improves, but the complexity of positioning and tensioning increases
Solution Approach 1:
The fixing sub-station and jig are designed to pre-position and pre-tension the membrane element before the stapling operation begins. The articulated arm system brings the stapler to the predetermined location on the already-tensioned membrane, ensuring optimal stapling conditions without requiring complex real-time tensioning mechanisms during the stapling process itself.

AI summary
An automatic station (1) to cover a support (7) with a membrane element (8), comprises an articulated arm (4), a stapler (5) moved by the articulated arm (4), a fixing sub-station (2) to retain the membrane element (8) in a predefined position on the support (7), and a gripping element (18) moved by the articulated arm (4) and adapted to hook an edge portion (9) of the membrane element (8) while the support (7) is retained by the fixing sub-station (2) to tension the edge portion (9) before the stapler (5) fixes the edge portion (9) to the support (7).
