Solution Overview

Problem

Existing window and door mounting systems lack the ability to easily adjust the mounting distance between the frame and the wall, as they are typically fixed by the size of the triangular plate, limiting adaptability to varying tolerances and frame positions.

Innovation Solution

A set of fittings featuring elongated mounting brackets and a support structure in the form of a tiltable or slidable support arm with a flat section that can bend to adapt to different positions, allowing flexible engagement with the mounting bracket for adjustable mounting distances.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a fixed mounting system with triangular plate is used, then the mounting distance is determined and stable, but the adaptability to varying tolerances and frame positions is limited

Engineering Contradiction:
Improveadaptability to varying tolerances and frame positionsVSAvoidmounting system structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The support arm is designed with tiltable and slidable features, allowing it to dynamically adjust its position and angle. The tiltable engagement mechanism enables the support arm to rotate relative to the mounting bracket, while the slidable feature allows movement along the longitudinal direction, providing dynamic adaptability to varying mounting conditions without requiring a completely complex redesign of the entire mounting system.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The mounting system allows changes in geometric parameters such as the angle between the support arm and mounting bracket, and the position along the longitudinal direction. These parameter changes enable the system to adapt to different tolerances and frame positions while maintaining a relatively simple overall structure, resolving the contradiction between adaptability and complexity.

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If the mounting distance is made adjustable, then the flexibility and ease of mounting are improved, but the structural simplicity may be compromised

Engineering Contradiction:
Improveease of mountingVSAvoidsupport structure design
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The support arm is segmented into functional areas: a first area with wall abutment for wall engagement, a second area for tiltable engagement with the mounting bracket, and a longitudinal direction for slidable engagement. This segmentation allows each part to perform its specific function independently, enabling easy mounting and adjustment without requiring a complex integrated design.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The support arm acts as an intermediary element between the mounting bracket and the wall, providing flexible engagement at both ends. The tiltable and slidable features of the support arm serve as intermediary mechanisms that translate between the fixed mounting bracket and the adjustable wall position, enabling easy mounting while maintaining structural simplicity.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If a tiltable support arm with multiple engagement positions is used, then the adaptability to different frame positions is improved, but the device complexity increases

Engineering Contradiction:
Improvemounting distance adjustmentVSAvoidsupport arm mechanism
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The support arm incorporates dynamic engagement mechanisms including tiltable connection to the mounting bracket and slidable connection along the longitudinal direction. These dynamic features allow the support arm to adapt to different frame positions and mounting distances through simple movements, providing adjustability without requiring complex mechanical systems.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The support arm is designed with multi-functionality, serving both as a structural support element and as an adjustable mounting mechanism. The same support arm structure provides wall abutment, tiltable engagement with the mounting bracket, and slidable engagement along its length, enabling it to handle multiple mounting scenarios without adding separate complex mechanisms for each function.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

The set of fittings comprises a number of mounting brackets (1) having a first area (6) to be mounted on a face (7) of a window or door opening (4) in an inner wall (5) and a second area (8) to be mounted on a face (9) of the fixed frame (3). At least one support structure (2,34) is adapted for engagement with a corresponding mounting bracket (1) and is provided with a wall abutment (18,40) adapted to abut the inner wall (5) at a distance from the window or door opening. The position of the wall abutment (18,40) is adjustable relative to the corresponding mounting bracket (1) in a longitudinal direction of the mounting bracket (1).
