Solution Overview

Problem

Existing screening arrangements for skylight windows face challenges in mounting and design due to the restricted space between the weather shield and the window, making installation cumbersome and requiring complex configurations to ensure stability and sealing.

Innovation Solution

A screening arrangement with a suspension device that connects to the skylight window, featuring flanges that provide a stable and flexible mounting system, with hooks and gaskets for secure engagement and sound-dampening, allowing for easy installation and compact configuration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the screening arrangement is installed in the restricted space between the weather shield and the skylight window, then the screening function is achieved, but the mounting becomes cumbersome and complex

Engineering Contradiction:
Improveease of mountingVSAvoidmounting complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The suspension device is divided into separate functional components: flanges for connection, hooks for engagement, and support elements for stabilization. This segmentation allows each component to be optimized independently and simplifies the overall mounting process by enabling modular assembly and disassembly.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The suspension device acts as an intermediary element between the screening device and the skylight window structure. It provides a dedicated mounting interface that simplifies the connection process and distributes mechanical loads, making the installation easier while reducing the complexity of direct attachment.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Volume of moving object

If the screening device is configured to fit tightly in the limited space, then space utilization is improved, but stability and sealing become difficult to ensure

Engineering Contradiction:
Improvespace utilizationVSAvoidmounting stability
Core Design Contradiction:
Volume of moving objectVSReliability

Solution Approach 1:

The flanges are designed with localized connection features at specific positions to engage with the skylight window structure. This local quality approach ensures stable mounting at critical points while maintaining a compact overall configuration that fits within the limited space between the weather shield and window.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The suspension device extends in multiple dimensions with flanges protruding from the top casing and side rails. This three-dimensional configuration provides both compact space utilization and multiple engagement points for stability, resolving the contradiction between tight fitting and secure mounting.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Reliability

If the flanges are positioned to extend beyond the outer perimeter of the screening device, then connection stability is improved, but the compact configuration is compromised

Engineering Contradiction:
Improveconnection stabilityVSAvoidcompact configuration
Core Design Contradiction:
ReliabilityVSShape

Solution Approach 1:

The suspension device is segmented into functional zones: the screening device maintains its compact rectangular perimeter, while the flanges and hooks extend as separate connection elements. This segmentation allows the main body to remain compact while connection features extend outward for stable engagement with the skylight window structure.

Inventive Principle:
Principle #1Segmentation

AI summary

The screening arrangement (50) comprises a screening device (60) and a suspension device (70). The suspension device (70) comprises the means for connecting the screening device (60) to a skylight window (1) in that flanges (71, 72, 73, 74) of the suspension device (70) are associated to and protrude from the top casing (61), the side rail(s) (63, 64) and/or the bottom profile (62) to define a line of contact (LC1, LC2, LC3, LC4) located outside the outer perimeter of the screening device (60).
