Solution Overview

Problem

Existing heat insulated door and window systems with fixed angular turning profiles fail to address building construction and fenestration tolerances, leading to inadequate heat insulation at corner zones and limitations in adjusting angles, and cannot be used for both inward and outward openings with the same profile.

Innovation Solution

The system employs special geometrically shaped inner and outer cover profiles and joint profiles manufactured at extrusion presses, allowing for adjustable angular connections without thermal break profiles, using weatherproof gaskets and insulation material to maintain heat insulation across various angles, and enabling the same profile to be used for both inward and outward openings.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If fixed angle turning profiles are used, then manufacturing and assembly are simplified, but adaptability to different angles and construction tolerances is lost

Engineering Contradiction:

Improvemanufacturing simplicityVSAvoidangle adaptability

Core Design Contradiction:

Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The turning profile is designed with a movable joint mechanism that allows dynamic adjustment of the angle between two fenestrations. The joint includes movable connection elements that can be positioned at different angular orientations, enabling the system to adapt to various angles while maintaining a standardized profile design for manufacturing.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The turning profile incorporates adjustable parameters through movable connection points and modular components that can be repositioned. This allows the same profile structure to accommodate different angular configurations by changing the relative positioning of connection elements rather than requiring different profile geometries.

Inventive Principle:

Principle #35Parameter changes

2Loss of energy

If thermal break profiles are used, then heat insulation is improved, but device complexity and assembly difficulty increase

Engineering Contradiction:

Improveheat insulation performanceVSAvoidprofile structure complexity

Core Design Contradiction:

Loss of energyVSDevice complexity

Solution Approach 1:

The thermal break profile is divided into separate modular segments that can be assembled independently. The thermal break component is separated from the structural profile elements, allowing each to be optimized and manufactured separately, then connected through standardized joining mechanisms that reduce overall assembly complexity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A simplified intermediary connection element is introduced that bridges the thermal break profile and the structural profile. This intermediary component handles the complex thermal break integration while presenting a simple connection interface to the rest of the assembly system, reducing overall assembly difficulty.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Adaptability or versatility

If adjustable turning profiles are used, then adaptability to angles and tolerances is improved, but assembly difficulty increases

Engineering Contradiction:

Improveangle adjustabilityVSAvoidassembly ease

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The adjustable turning profile incorporates pre-configured alignment features and guide elements that automatically position components during assembly. The movable joint mechanisms are pre-biased into correct orientations, and alignment pins or guides are built-in to facilitate straightforward connection without requiring complex manual adjustment procedures.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The adjustable turning profile employs self-aligning and self-locking mechanisms that automatically adjust to the correct configuration during assembly. The movable connection elements feature self-guiding paths and automatic positioning features that eliminate the need for complex manual alignment procedures, making the adjustable system as easy to assemble as fixed systems.

Inventive Principle:

Principle #25Self-service

4Ease of operation

If corner turning profiles without thermal break are used, then assembly is simplified, but heat insulation at corner zones deteriorates

Engineering Contradiction:

Improveassembly simplicityVSAvoidcorner zone heat insulation

Core Design Contradiction:

Ease of operationVSLoss of energy

Solution Approach 1:

The solution merges the structural profile, thermal break elements, and corner turning functionality into an integrated corner piece. The thermal break material is incorporated directly into the corner turning profile structure, combining heat insulation and angular connection functions in a single component that maintains assembly simplicity while ensuring continuous thermal insulation at corner zones.

Inventive Principle:

Principle #5Merging (Combining)
