Solution Overview

Problem

The existing window systems with two-side supporting frames face challenges in maintaining good thermal insulation and secure glass panel fixing, especially when the aluminum metal outer cap does not extend to the overlapping portion, leading to structural weaknesses and excessive deformation under strong winds.

Innovation Solution

A window chassis insulating structure with glass support insulation brackets attached to the sides, aluminum side chassis portions, protruding edge portions, and elastic insulating support assemblies, including rigid support members made of reinforced synthetic resin, which are wedged into the side elastic insulating support assemblies to control deformation and increase the holding force of the glass panels.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If the aluminum metal outer cap does not extend to the overlapping portion, then thermal insulation performance is improved, but structural strength and glass panel fixing stability deteriorate

Engineering Contradiction:
Improvethermal insulation performanceVSAvoidglass panel fixing stability
Core Design Contradiction:
Loss of energyVSStrength

Solution Approach 1:

The patent employs composite materials by combining aluminum metal outer cap with synthetic resin inner cap and glass support insulation brackets. The synthetic resin material provides both thermal insulation properties and sufficient structural strength to maintain glass panel fixing stability, thereby resolving the contradiction between thermal insulation performance and structural strength when the aluminum cap does not extend to the overlapping portion.

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The patent applies local quality by providing different materials at different locations: the aluminum metal outer cap is used where structural strength is critical, while the synthetic resin inner cap is used at the overlapping portion where thermal insulation is prioritized. The glass support insulation brackets are strategically positioned to provide localized reinforcement, allowing the system to achieve both thermal insulation performance and glass panel fixing stability in different regions.

Inventive Principle:
Principle #3Local quality

2Adaptability or versatility

If the chassis width is reduced to about 40 mm for wide openness, then openness and aesthetics are improved, but thermal insulation performance and structural rigidity deteriorate

Engineering Contradiction:
ImproveopennessVSAvoidthermal insulation performance
Core Design Contradiction:
Adaptability or versatilityVSLoss of energy

Solution Approach 1:

The patent uses composite materials consisting of synthetic resin inner cap and glass support insulation brackets to achieve adequate thermal insulation performance in the narrow 40 mm chassis width. The combination of insulating materials compensates for the reduced thickness, maintaining thermal insulation performance while enabling wide openness and aesthetic design.

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The patent changes material parameters by selecting synthetic resin with specific insulating properties and designing the glass support insulation brackets with optimized geometry. These parameter changes allow the narrow chassis to achieve sufficient thermal insulation performance despite the reduced width, thereby maintaining both openness and energy efficiency.

Inventive Principle:
Principle #35Parameter changes

3Loss of energy

If the glass support insulation brackets are made of soft material without aluminum chassis support, then thermal insulation is improved, but resistance to wind pressure and deformation control deteriorate

Engineering Contradiction:
Improvethermal insulationVSAvoidresistance to wind pressure
Core Design Contradiction:
Loss of energyVSReliability

Solution Approach 1:

The patent employs composite materials by combining soft glass support insulation brackets with synthetic resin inner cap. This combination maintains the thermal insulation benefits of soft materials while the synthetic resin provides the necessary structural support and resistance to wind pressure, preventing excessive deformation and ensuring reliability under strong wind conditions.

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The patent applies beforehand cushioning by designing the glass support insulation brackets with soft material to absorb and cushion wind pressure loads before they can cause damage. The brackets are pre-configured to deform elastically under wind pressure, protecting the glass panels and overall structure from excessive deformation while maintaining thermal insulation performance.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)
