Solution Overview

Problem

Existing ventilation devices for sliding doors and windows are not space-efficient and require additional operating handles, and they do not seamlessly integrate with the sliding sash when in a closed position, as they often require a large fixed frame and protruding components.

Innovation Solution

A space-saving ventilation profile that integrates with the sliding sash and fixed frame, featuring a groove system and locking pins that allow the ventilation profile to be hidden when closed, and can be easily moved without additional handles, with the option to be retrofitted onto existing components.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the ventilation profile is mounted displaceably on the frame piece with a telescopic structure, then ventilation function is achieved, but a large amount of space is required in or on the fixed frame

Engineering Contradiction:
Improveventilation functionVSAvoidfixed frame space
Core Design Contradiction:
ReliabilityVSVolume of stationary object

Solution Approach 1:

The ventilation profile is inserted into a groove in the fixed frame when the sliding sash is closed, nesting the ventilation component within the frame structure. This eliminates the need for additional external space while maintaining the ventilation function when needed.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The ventilation profile utilizes the groove dimension within the fixed frame structure rather than requiring external protruding space. By moving the ventilation profile along the groove and locking it in position, the system achieves ventilation functionality without increasing the overall frame volume.

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

2Shape

If the ventilation profile is completely absorbed by the fixed frame leg, then it is not visible when closed, but a large amount of space is required for the telescopic structure

Engineering Contradiction:
Improveaesthetic integrationVSAvoidfixed frame space
Core Design Contradiction:
ShapeVSVolume of stationary object

Solution Approach 1:

The ventilation profile is nested within the groove of the fixed frame when not in use, making it completely invisible and maintaining the aesthetic appearance of the closed sliding sash. The groove provides the necessary space without requiring external protrusions.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Ease of operation

If additional operating handles are added to move the ventilation profile, then ventilation positioning is achieved, but device complexity increases

Engineering Contradiction:
Improveventilation positioningVSAvoidoperating mechanism
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The ventilation profile is moved and locked automatically as the sliding sash opens and closes. The locking pin engages with the ventilation profile at appropriate positions during the natural movement of the sliding sash, eliminating the need for separate operating handles or additional control mechanisms.

Inventive Principle:
Principle #25Self-service

4Reliability

If locking pins protrude beyond the fixed frame, then locking function is achieved, but damage risk increases

Engineering Contradiction:
Improvelocking functionVSAvoiddamage risk
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The locking pin is received within the groove of the fixed frame when the sliding sash is closed, preventing it from protruding and causing damage. The groove provides a protective recess that contains the locking mechanism while maintaining its locking functionality when the sash is open.

Inventive Principle:
Principle #7Nested doll (Nesting)

AI summary

The ventilation device has a ventilation profile (6) which is formed such that a space between sliding wing (2) and fixed frame is formed in a ventilation position. The wing is inserted into a groove in the fixed frame in closed position. A locking pin (18) is provided to lock the sliding wing with the fixed frame in the ventilation and closed positions. Independent claims are included for the following: (1) fitting for sliding wing of sliding door or window; and (2) method for re-tooling sliding door or window with a sliding wing.
