Formwork Wall Accessory Coupling Sleeve Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing railing installation devices integrated into building formwork walls are prone to damage from slings, cables, and other flexible accessories, which can compromise the stability and safety of the railings.
Innovation Solution
A hooking sheath with a rectilinear structure that includes a continuous inclination at its second end, allowing it to be integrated into a vertical wall structure during formwork production, thereby minimizing interference with flexible accessories and enhancing stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sheaths are integrated into walls as projecting reliefs to provide stable guardrail installation, then the stability and safety of guardrails is improved, but the sheaths are likely to be accidentally torn off by flexible accessories like slings and cables moving against the walls
Solution Approach 1:
The invention extracts the vulnerable projecting sheath from the wall surface and replaces it with a recessed sheath integrated into the wall thickness. The coupling sleeve is positioned within the wall structure rather than protruding outward, so flexible accessories like slings and cables pass by without contacting the sheath, eliminating the risk of accidental damage while maintaining guardrail stability.
Solution Approach 2:
The coupling sleeve is nested within the wall thickness, with part of the sleeve embedded in the wall structure and part extending outward. This nesting approach allows the sheath to be protected within the wall while still providing the necessary interface for guardrail installation, avoiding exposure to external flexible accessories.
2Ease of operation
If sheaths are integrated into walls to ensure easy dismantling and reassembly of guardrails, then the ease of operation is improved, but the projecting reliefs obstruct the movement of flexible accessories against the wall surfaces
Solution Approach 1:
The invention removes the projecting relief feature from the wall surface by integrating the coupling sleeve recessed into the wall thickness. This eliminates the obstruction to flexible accessories while preserving the coupling mechanism's functionality for easy guardrail assembly and dismantling.
Solution Approach 2:
Instead of projecting the sheath outward from the wall surface, the invention inverts the approach by recessing the sheath into the wall thickness. This inversion resolves the conflict between ease of operation and obstruction of flexible accessories by placing the coupling interface within the wall structure rather than on its surface.
3Ease of operation
If coupling sleeves are positioned outside the wall to facilitate guardrail installation, then the ease of operation is improved, but the sleeves become vulnerable to damage from flexible accessories moving against the walls
Solution Approach 1:
The coupling sleeve is nested within the wall thickness, with a portion embedded in the wall and a portion extending outward to receive the guardrail. This nested configuration provides both ease of installation (the outward portion is accessible) and reliability (the embedded portion is protected from damage by flexible accessories).

AI summary
The object of the present invention relates to an accessory attachment sleeve (1) characterized in that the sleeve (1) comprises: - an axial straight structure (2) with an outer surface and an inner surface defining a housing (3) with an opening at one end (21), - a cooperation interface (4) fixed to the straight structure (2) and whose end provides non-aligned support points (4c) for positioning the straight structure (2) parallel to the plane of the support points (4c) of the cooperation interface (4), and in that, in a plane comprising the axis of the straight structure (2) and perpendicular to the plane of the support points (4c) of the cooperation interface (4), the second end (22) of the straight structure (2) comprises a continuous inclination between the two portions of outer surface (23, 24) positioned on either side of the axis of the straight structure (2).
