Solution Overview

Problem

Existing screen mounting systems face challenges when dealing with irregularly shaped openings, as they require precise measurements and uniform tension across the screening sheet, which is difficult to achieve due to the non-parallel and non-perpendicular sides of the opening, leading to aesthetic defects and early wear.

Innovation Solution

The introduction of adjustable anchoring brackets that allow for precise adjustment of the distance between the profile and the opening, using a snap-fit mechanism and flexible gaskets to ensure correct alignment and tension, enabling easy installation and removal of the screen without losing adjusted positions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If profiles are fixed directly on the sides of the opening, then the installation process is simple, but the screen cannot maintain uniform tension and proper alignment in irregular openings

Engineering Contradiction:
Improveinstallation simplicityVSAvoidalignment precision
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The patent introduces adjustable brackets as intermediary elements between the opening and the screen profiles. These brackets are mounted on the opening sides and provide adjustable attachment points that mediate between the irregular opening geometry and the rectangular screen requirements, enabling both simple installation and precise alignment.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The brackets incorporate adjustable mechanisms that allow dynamic positioning during installation. The adjustability enables the brackets to adapt to irregular opening dimensions and angles, allowing installers to achieve proper alignment without complex custom fabrication or difficult adjustment procedures.

Inventive Principle:
Principle #15Dynamics

2Manufacturing precision

If measurements are taken precisely to fit irregular openings, then the screen alignment improves, but the installation time and complexity increase

Engineering Contradiction:
Improvescreen alignmentVSAvoidinstallation time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The brackets are designed with pre-configured adjustment mechanisms and mounting features that prepare the system for precise alignment before the screen installation. The brackets can be pre-adjusted to the correct positions and angles, so that when the screen profiles are attached, proper alignment is achieved without time-consuming on-site measurements and adjustments.

Inventive Principle:
Principle #10Preliminary action

3Manufacturing precision

If the screen is fixed rigidly to maintain tension, then uniform tension is achieved, but the screen cannot be easily removed for maintenance

Engineering Contradiction:
Improvetension uniformityVSAvoidmaintenance accessibility
Core Design Contradiction:
Manufacturing precisionVSEase of repair

Solution Approach 1:

The patent divides the fixed connection into separable components: the brackets are firmly mounted to the opening to maintain structural stability and tension, while the connection between brackets and screen profiles uses detachable fastening mechanisms. This segmentation allows the screen to be easily removed from the brackets for maintenance while the brackets remain securely installed.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The fastening system incorporates dynamic elements that provide rigid fixation during normal operation to maintain uniform tension, but can be easily released when maintenance is needed. The adjustable and detachable nature of the bracket-screen connection allows transition between stable operation and easy maintenance modes.

Inventive Principle:
Principle #15Dynamics

AI summary

An anchoring system with adjustable brackets to facilitate mounting of screens such as solar shades and fly screens inside irregular openings (5) for windows or doors, of the type comprising a screening sheet (6), a box (4), guides (3) and a handle (15), wherein the profiles forming the elements of the screen can be secured onto the respective sides of the opening by the interposition of specific fixing brackets (1,1', 1"), on which said profiles can be snappingly restrained. The brackets(1, 1', 1") can be moved away from/close to the corresponding side of the opening, since they are axially integral with the head of a fastening screw (2) which is operatively connected to the bracket (1, 1', 1") and can be screwed to the side of the opening (5).
