Adjustable Mounting Frame for Irregular Window Openings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing window, door, and shutter installation methods face challenges with inaccurate measurements, leading to fitting issues, where the product may be too large or small for the opening, resulting in the need for packing that can cause pressure points and long-term misalignment.
Innovation Solution
An adjustable mounting frame system with movable frame members and threaded mechanisms allows for size and shape adjustments to fit irregularly sized or out-of-square openings, using a rigid surround frame with infill portions and adjustable frame members that can expand to fit the opening accurately.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a fixed-size window, door, or shutter is manufactured based on preformed opening dimensions, then manufacturing precision can be maintained, but the product may not fit due to measurement errors or irregular openings
Solution Approach 1:
The mounting frame incorporates adjustable members that can be moved relative to each other, transforming a static fixed-size frame into a dynamic adjustable frame. This allows the frame to adapt its dimensions to match irregular or non-standard openings while maintaining the original product dimensions, resolving the contradiction between manufacturing precision and adaptability
Solution Approach 2:
The mounting frame allows change in its dimensional parameters (length, width, shape) through adjustable members that can be positioned at different locations. This parameter adjustment capability enables the frame to accommodate various opening sizes and shapes without requiring custom manufacturing of the window, door, or shutter itself
2Adaptability or versatility
If packing material is used to fill gaps between the product and opening periphery, then the product can be fitted to the opening, but pressure points are created causing the product to sag out of shape over time
Solution Approach 1:
The adjustable mounting frame acts as an intermediary structure between the window/door/shutter and the opening. Instead of using packing material directly at the product-periphery interface, the mounting frame provides a stable structural mediator that distributes loads evenly and maintains alignment, eliminating the pressure point problem while still achieving a proper fit
3Reliability
If the mounting frame is made rigid to maintain product stability, then alignment can be maintained, but the frame cannot accommodate irregular or out-of-square openings
Solution Approach 1:
The mounting frame transitions from a completely rigid structure to a dynamic structure with adjustable members that can move relative to each other. This allows the frame to adapt its geometry to irregular openings while maintaining stability once positioned, resolving the contradiction between rigidity for alignment and flexibility for accommodation

AI summary
A window, shutter or door assembly including a window, shutter or door including a rigid surround frame with a number of peripheral sides and an adjustable mounting frame including at least one frame member relative to each peripheral side of the rigid surround frame of the window, shutter or door and movable relative thereto to abut part of a periphery of an opening into which the window, shutter or door assembly is to be fitted to adjust the size of the adjustable mounting frame in one or more dimensions to fit the opening.
