Solution Overview

Problem

The installation of windows with hinges featuring linkage mechanisms is challenging due to the inherent connection between the frame and sash hinge parts, making it difficult for one person to mount and dismount the window sash without causing damage, especially in confined spaces like roof windows where limited transverse movement is available.

Innovation Solution

The use of mounting plates on the frame member allows for facilitated installation by enabling the hinge components to engage in a plane parallel to the hinge plane, eliminating the need for transverse movements and avoiding the use of penetrating fastening elements, thus allowing for easy connection and disconnection without damaging components or requiring additional personnel.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional pivot hinges with inherent connection between frame and sash hinge parts are used, then the hinge provides stable structural connection, but the installation becomes difficult and requires multiple persons due to limited transverse movement space

Engineering Contradiction:

Improvestructural connection stabilityVSAvoidinstallation ease

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The hinge is divided into separate components: a frame hinge part that is pre-mounted on the frame, and a sash hinge part that is attached to the sash. This segmentation allows the frame hinge part to be installed first in the limited space, followed by the sash hinge part, enabling single-person installation while maintaining stable structural connection through the coupling means.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The frame hinge part is pre-mounted on the frame before the sash is installed. This preliminary action prepares the mounting position in advance, so that when the sash is brought into position, the coupling means can easily engage with the pre-positioned frame hinge part without requiring complex transverse movements or multiple persons.

Inventive Principle:

Principle #10Preliminary action

2Adaptability or versatility

If hinges with linkage mechanisms are used, then the desired movement pattern is achieved, but the mounting process becomes complex and damaging to components due to the inherent connection between frame and sash parts

Engineering Contradiction:

Improvemovement pattern capabilityVSAvoidmounting simplicity

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The linkage mechanism is segmented into the frame hinge part (with mounting arrangement) and the sash hinge part. This allows the complex linkage mechanism to be assembled and tested separately before installation, simplifying the mounting process and reducing the risk of component damage while preserving the desired movement pattern capability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The coupling means acts as an intermediary between the frame hinge part and the sash hinge part. It enables the connection of the linkage mechanism components without requiring direct manipulation of the linkage elements themselves, thereby simplifying the mounting process and protecting the components from damage.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Area of stationary object

If confined space installation is attempted with traditional hinges, then space utilization is optimized, but the degree of freedom for transverse movements is restrained making installation difficult

Engineering Contradiction:

Improveinstallation space utilizationVSAvoidtransverse movement freedom

Core Design Contradiction:

Area of stationary objectVSEase of operation

Solution Approach 1:

The frame hinge part is pre-mounted on the frame in the confined space before the sash is positioned. This eliminates the need for transverse movements during the final assembly, as the sash hinge part can be directly coupled to the pre-positioned frame hinge part, optimizing space utilization while maintaining installation ease.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

Instead of bringing the complete hinge assembly into the confined space and then attempting to install it, the invention inverts the approach by first installing the frame hinge part in the limited space, and then coupling the sash hinge part. This reversal of installation sequence makes it possible to work within the constrained transverse movement freedom.

Inventive Principle:

Principle #13The other way round (Inversion)

AI summary

In order to assist in mounting the hinge (210) on a window, the hinge comprises a mounting arrangement (250) including two mounting plates (251, 252) to be arranged on the frame of the window. The mounting arrangement includes at least one set of coupling means (253, 254) configured to engage with corresponding coupling means (263, 264) of the remaining components of the set of components of the hinge (210). The coupling means of the mounting arrangement (250) comprise at least one reception member (253, 254) provided on a respective mounting plate (251, 252) to engage with a respective engagement member (263, 264) of the coupling means of the remaining components by movement of the remaining components of the hinge substantially in parallel with said hinge plane to provide a releasable connection between the remaining components of the hinge (210) and the mounting plates (251, 252).
