Solution Overview

Problem

Existing window and door frames in buildings suffer from thermal bridging, require complex and costly finishing processes, lack versatility in design, and do not integrate security and remote monitoring systems, leading to inefficient thermal insulation and unsightly installations.

Innovation Solution

A connected insulating frame with a thermally insulated roller shutter box, customizable cladding, and integrated intrusion detection system, allowing pre-assembly for easy installation and improved air tightness, while maintaining architectural flexibility.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If metal subframes are used for installing exterior joinery, then structural strength and stability are improved, but thermal bridging increases and thermal insulation performance deteriorates

Engineering Contradiction:
Improvestructural strengthVSAvoidthermal bridging
Core Design Contradiction:
StrengthVSLoss of energy

Solution Approach 1:

The patent uses composite materials by combining metal profiles with thermal insulation materials. The subframe consists of metal profiles for structural strength, covered with thermal insulation material to eliminate thermal bridging, creating a composite structure that provides both mechanical support and thermal insulation performance.

Inventive Principle:
Principle #40Composite materials

2Loss of energy

If multi-stage finishing processes are carried out around subframes, then thermal insulation and aesthetic appearance are improved, but installation time and complexity increase

Engineering Contradiction:
Improvethermal insulationVSAvoidinstallation time
Core Design Contradiction:
Loss of energyVSLoss of time

Solution Approach 1:

The patent merges multiple functions into a single integrated subframe structure. The subframe combines structural support, thermal insulation, and aesthetic finishing elements into one pre-assembled unit, eliminating the need for separate multi-stage finishing processes and reducing installation time while maintaining thermal insulation performance.

Inventive Principle:
Principle #5Merging (Combining)

3Ease of operation

If roller shutter boxes are installed separately from subframes, then shutter functionality is achieved, but device complexity and installation complexity increase

Engineering Contradiction:
Improveshutter functionalityVSAvoidinstallation complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent integrates the roller shutter box directly into the subframe structure, merging two separate components into one unified assembly. This integration simplifies the overall device structure and reduces installation complexity while maintaining full shutter functionality, as the box is already positioned and configured within the subframe before installation.

Inventive Principle:
Principle #5Merging (Combining)

4Shape

If roller shutter boxes are recessed into the upper part of openings, then aesthetic appearance is improved, but storage space and glazed area are reduced

Engineering Contradiction:
Improveaesthetic appearanceVSAvoidstorage space
Core Design Contradiction:
ShapeVSVolume of stationary object

Solution Approach 1:

The patent relocates the roller shutter box from a recessed position within the opening plane to a position on the exterior face of the building. This dimensional change allows the box to be integrated into the facade structure without encroaching on the opening area, thereby preserving both the glazed area and storage space while maintaining aesthetic appearance through proper facade integration.

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