Solution Overview

Problem

Existing window frames with unequal uprights for movable frames are aesthetically unpleasing, complex to install, costly, and reduce glass surface area, compromising thermal and acoustic insulation.

Innovation Solution

A window frame design with equal-width internal uprights and integrated gaskets for hermetic sealing, eliminating the need for additional support elements, simplifying installation and reducing production costs while maintaining thermal and acoustic insulation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the internal upright of the movable frame with the handle is made wider to provide a striking surface parallel to the hole development, then thermal and acoustic insulation is improved and the closing/locking device can be hidden, but the aesthetic appearance deteriorates due to unequal upright widths

Engineering Contradiction:
Improvethermal and acoustic insulationVSAvoidaesthetic appearance
Core Design Contradiction:
ReliabilityVSShape

Solution Approach 1:

The invention resolves the aesthetic contradiction by moving the striking surface creation to a different dimensional approach - instead of making the upright itself wider, a support element is added that extends in depth (perpendicular to the facade) to create the parallel striking surface while keeping the upright width equal to the other frame's upright

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

Solution Approach 2:

A support element acts as an intermediary component between the upright and the striking surface, allowing the striking surface to be formed without increasing the upright width, thus maintaining aesthetic appearance while achieving the required functional surface

Inventive Principle:
Principle #24Intermediary (Mediator)

2Shape

If a support element is added to the narrower upright to create the striking surface, then the aesthetic appearance improves with equal-width uprights, but the device complexity and installation difficulty increase

Engineering Contradiction:
Improveaesthetic appearanceVSAvoidnumber of components
Core Design Contradiction:
ShapeVSDevice complexity

Solution Approach 1:

The support element is merged with the glazing bead to form a single integrated component, reducing the total number of parts from two separate elements (support element + glazing bead) to one combined element, thereby simplifying the device structure and installation process

Inventive Principle:
Principle #5Merging (Combining)

3Shape

If a support element is added to create the striking surface, then the aesthetic appearance improves, but the manufacturing cost increases due to additional components

Engineering Contradiction:
Improveaesthetic appearanceVSAvoidproduction cost
Core Design Contradiction:
ShapeVSEase of manufacture

Solution Approach 1:

By combining the support element and glazing bead into a single integrated component, the manufacturing process is simplified, reducing production costs associated with making, inventorying, and assembling multiple separate parts while maintaining the aesthetic benefit of equal-width uprights

Inventive Principle:
Principle #5Merging (Combining)

4Shape

If a support element is added to create the striking surface, then the aesthetic appearance improves, but the glass surface area is reduced

Engineering Contradiction:
Improveaesthetic appearanceVSAvoidglass surface area
Core Design Contradiction:
ShapeVSArea of stationary object

Solution Approach 1:

The striking surface is created by extending the support element in depth (perpendicular dimension) rather than increasing the horizontal width, allowing the glass surface area to remain maximized while still providing the required parallel striking surface for proper frame closure

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

AI summary

SUMMARY Frame (1) for closing a hole (4) and separating an internal environment (6) from an external environment (6') comprising a pair of movable frames (10, 10'), each comprising: - an internal upright (12, 12'), - an external upright (13, 13'), - a lower current (15, 15') - a higher current (16, 16'), wherein an internal upright (12) comprises a first (14) and a second (18) face, and the other internal upright (12') comprises a further first (14) and a further second (14') face, - said first (14) and said further first (14) face comprising first facing portions (30, 30') configured to be mutually facing when the frame is in the closed condition, a bolt portion (32, 32') configured to house, at least partially, at least one locking mechanism of said frame, and adjacent to said first face (28, 28'), - said second (28) and said further second (28') face having a substantially equal horizontal development, and characterised in that in at least one of said first faces (14, 14') a first housing (38) is obtained configured to house, at least partially, a first shaped gasket (36), said first shaped gasket being configured to abut said further first face (14',14) and/or one of its components in order to close the frame (1).
