Screening Device Anchoring Mechanism for Easy Window Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current fly net installation methods are cumbersome, requiring skilled labor and multiple holes in architectural elements, making them difficult to install, remove, and reverse, which discourages users from using them effectively.
Innovation Solution
The fly net design features anchoring members with inserts and removable engagement devices that allow for easy installation and reinstallation without skilled labor, enabling direction reversal and simplified maintenance, using thrust devices and conical control wheels for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the fixed upright and auxiliary upright are anchored by means of a plurality of cleats requiring drilling holes in masonry parts and architectural elements, then the screening device can be securely fixed, but the installation becomes complex and requires skilled labor
Solution Approach 1:
The anchoring system is divided into separate components: a guide bar that can be fixed to the window frame and anchoring members that attach the screening device to the guide bar. This segmentation allows each component to be installed independently using simpler methods, avoiding the need for complex multi-point anchoring directly to architectural elements.
Solution Approach 2:
A guide bar is introduced as an intermediary element between the window frame and the screening device. The guide bar serves as a mounting rail that simplifies the anchoring process, allowing the screening device to be attached to the guide bar rather than directly to the window frame, thereby reducing installation complexity while maintaining fixing strength.
2Strength
If multiple holes are drilled in architectural elements for anchoring, then secure fixation is achieved, but damage to architectural elements occurs and restoration becomes difficult
Solution Approach 1:
The anchoring function is extracted from the architectural elements themselves and transferred to a separate guide bar system that can be attached to the window frame. This extraction eliminates the need to drill holes in valuable architectural elements like marble or wood, preventing damage while maintaining secure fixation through the removable guide bar and anchoring members.
3Stability of the object's composition
If the screening device is permanently installed with multiple anchoring points, then stability is ensured, but easy removal and reinstallation by end users becomes impossible
Solution Approach 1:
The anchoring members are designed with dynamic characteristics, featuring engagement projections that can be easily inserted into and removed from sealing seats. This allows the screening device to be securely fixed during use but easily removed and reinstalled by end users without requiring specialized tools or skills, while maintaining stability during operation.
4Reliability
If the screening device uses fixed anchoring components, then reliable fixation is achieved, but adaptability for different installation directions and locations is reduced
Solution Approach 1:
The guide bar and anchoring members are designed as universal components that can be installed in different locations and orientations on various window types. The anchoring members with engagement projections can be positioned at different points along the guide bar, allowing the screening device to be adapted for different installation directions (left or right opening) and locations while maintaining reliable fixation.

AI summary
A screening device comprising an upper guide (2) engageable along an upper side of a window, a lower guide (3) engageable along a lower side of the window, and a shielding assembly (4) comprising an upright (5), a movable bar (6) parallel to the upright (5) and a screening sheet (7) having mutually opposite end edges, respectively engaged to the movable bar (6) and to the upright (5). At least the upper guide (2) comprises a section bar (2a) having opposite ends slidably engaged with respect to coupling terminals (12). Thrust devices (46) configured to push opposite ends of the upper guide (2) mutually moving away which operate between the section bar (2a) and the coupling terminal (12) at, at least, one of the opposite ends of the upper guide (2), to push said section bar (2a) and coupling terminal (12) in opposite directions respectively.
