Solution Overview

Problem

Existing methods for installing windows in tilt-up concrete walls involve complex frame structures that are cumbersome and do not efficiently form chamfers, leading to potential damage, moisture issues, and aesthetic concerns.

Innovation Solution

A system utilizing a single extrusion frame with integrated spurs and forms that create chamfers during concrete casting, along with adjustable louvers and insulation layers, to enhance structural integrity and aesthetics.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a complex frame structure is used to install windows in tilt-up concrete walls, then the window can be securely installed, but the installation becomes cumbersome and less efficient

Engineering Contradiction:

Improvewindow installation securityVSAvoidframe structure complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines the frame structure and chamfer formation into a single integrated component. The frame includes integrated chamfer-forming elements that automatically create the chamfer geometry during concrete pouring, eliminating the need for separate chamfer formation steps and reducing overall system complexity while maintaining secure window installation

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The frame structure serves multiple functions simultaneously: it provides structural support for the window, forms the chamfer geometry through its integrated elements, and ensures proper positioning during concrete pouring. This multi-functionality reduces the number of separate components needed and simplifies the overall installation process

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Manufacturing precision

If traditional window installation methods are used in tilt-up walls, then windows can be installed, but chamfers are not efficiently formed leading to potential damage and moisture issues

Engineering Contradiction:

Improvechamfer formation qualityVSAvoidmoisture ingress and damage risk

Core Design Contradiction:

Manufacturing precisionVSObject-affected harmful factors

Solution Approach 1:

The frame structure is pre-configured with chamfer-forming elements before the concrete is poured. These elements are positioned in advance to ensure that when the concrete is poured and cured, the chamfers are automatically formed with precise geometry, eliminating the need for post-construction chamfer formation and ensuring proper moisture management from the start

Inventive Principle:

Principle #10Preliminary action

3Strength

If a single extrusion frame is used, then structural rigidity is improved, but the frame must be designed to integrate multiple functions

Engineering Contradiction:

Improvestructural rigidityVSAvoidintegrated frame design complexity

Core Design Contradiction:

StrengthVSDevice complexity

Solution Approach 1:

The patent merges multiple functions into a single extrusion frame: structural support, chamfer formation, and window positioning. The frame includes integrated chamfer-forming elements and positioning features that are all part of the same continuous extrusion, providing structural rigidity while simplifying the overall design compared to multiple separate components

Inventive Principle:

Principle #5Merging (Combining)
