Solution Overview

Problem

Existing mounting brackets for window frames in inclined roof surfaces often result in obliquity between the window frame and window sash due to erroneous installation or roof settlement, requiring inconvenient uninstallation and reinstallation.

Innovation Solution

A mounting bracket with an angular bracket member and base member, featuring a stud with a screw thread and slot adjustment mechanism, allowing for relative adjustment along multiple axes without uninstalling the window frame, using a hex-key for tightening and untightening, and optionally including a fixation pin for secure attachment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the window frame is installed using a conventional mounting bracket, then the window frame is securely mounted in the roof, but obliquity between the window frame and window sash occurs due to erroneous installation or roof settlement, requiring inconvenient uninstallation and reinstallation

Engineering Contradiction:
Improvesecure mountingVSAvoidadjustability
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The mounting bracket transitions from a static rigid connection to a dynamic adjustable connection through the slot mechanism. The slot in the first leg of the angular bracket member allows the base member to move relative to the angular bracket, enabling adjustment of the window frame position after installation to eliminate obliquity while maintaining secure mounting.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The mounting bracket is divided into separable components (angular bracket member, base member, locking means) with a slot mechanism that allows relative movement between segments. This segmentation enables independent adjustment of the base member position relative to the angular bracket while maintaining overall structural integrity.

Inventive Principle:
Principle #1Segmentation

2Manufacturing precision

If the window frame is uninstalled and reinstalled to remove obliquity, then proper alignment is achieved, but the process is inconvenient and requires removal of roof tiles

Engineering Contradiction:
Improvealignment precisionVSAvoidinstallation time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The slot mechanism provides dynamic adjustability that allows alignment corrections to be made in-situ without complete disassembly. The locking means can be engaged or disengaged to allow or prevent movement, enabling precise alignment adjustment while the window frame remains mounted, saving time and avoiding roof tile removal.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The slot is pre-formed in the angular bracket member during manufacturing, providing built-in adjustment capability before installation. This preliminary design feature eliminates the need for post-installation disassembly and reassembly, allowing direct in-situ adjustment to achieve proper alignment.

Inventive Principle:
Principle #10Preliminary action

3Stability of the object's composition

If the mounting bracket uses a rigid fixed connection, then structural stability is maintained, but adjustment of the window frame position is not possible

Engineering Contradiction:
Improvestructural stabilityVSAvoidposition adjustability
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The mounting bracket employs a dynamic connection system where the slot allows controlled movement between the angular bracket member and base member. The locking means (screw thread member) can engage with the slot to lock the position or disengage to allow adjustment, providing both structural stability when locked and position adaptability when adjusted.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The slot acts as an intermediary element between the angular bracket member and base member, mediating between the need for structural stability and position adjustability. The locking means engages with this intermediary to either constrain or allow movement, reconciling the contradictory requirements of stability and adaptability.

Inventive Principle:
Principle #24Intermediary (Mediator)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

Enables adjustment of the window frame and sash relative positions without removing the window frame, addressing obliquity issues caused by roof settlement or installation errors, allowing for precise alignment without disassembly.

Implementation Method 1

The locking means is comprised by a stud member (7) having a head member (71) and a screw thread member (73) and an opening (53) in the base member (5) with screw threads for receiving the screw thread member (73) of the stud (7). By tightening the stud to the base plate, the angular bracket member and the base member are interlocked.
