Solution Overview

Problem

Conventional sliding window designs require a large number of profiles for each specific application, leading to higher manufacturing and storage costs.

Innovation Solution

A modular profile system with a single main profile and multiple sash profiles, allowing for a variety of installation positions and designs without needing numerous profile types, featuring a frame module, sealing module, insulating module, and locking module to optimize manufacturing and storage costs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional sliding window designs use multiple profile types for different applications, then adaptability to specific applications is improved, but manufacturing costs and storage costs increase

Engineering Contradiction:

Improveadaptability to specific applicationsVSAvoidmanufacturing costs

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent applies universality by designing a main profile with a standardized cross-section that can serve multiple functions across different sliding window applications. The main profile includes a guide channel and sealing surface that work with various sash profiles, allowing a single profile type to adapt to different installation positions and design requirements through configuration rather than customization of the profile itself.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent segments the sliding window system into modular components: a standardized main profile forming the frame structure, and interchangeable sash profiles that can be configured in different arrangements (single sash, double sash, left-side opening, right-side opening). This segmentation allows the universal main profile to work with multiple sash configurations without requiring different main profiles for each application.

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If conventional sliding window designs use multiple profile types for different applications, then adaptability to specific applications is improved, but storage costs increase

Engineering Contradiction:

Improveadaptability to specific applicationsVSAvoidstorage costs

Core Design Contradiction:

Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The universal main profile design reduces the variety of profile types that need to be stored. By making the main profile adaptable through standardized interfaces and configuration options rather than through physical variation, the system reduces inventory requirements while maintaining application-specific adaptability.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent uses parameter changes (such as the position and orientation of sash profiles relative to the main profile, and configurable sealing arrangements) rather than physical profile variations to achieve adaptability. This allows the same profile geometry to serve multiple applications by changing assembly parameters rather than requiring different profile types in storage.

Inventive Principle:

Principle #35Parameter changes

3Ease of manufacture

If a modular profile system with fewer profile types is used, then manufacturing costs and storage costs are reduced, but the ability to accommodate specific application requirements must be maintained

Engineering Contradiction:

Improvemanufacturing costsVSAvoidaccommodation of specific application requirements

Core Design Contradiction:

Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The main profile is designed with universal features including a guide channel that can accommodate different sash profile types, sealing surfaces that work with various configurations, and mounting interfaces that adapt to different installation positions. This universality allows a single profile type to meet specific application requirements through configuration rather than customization.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

While the overall profile geometry is standardized, the patent applies local quality by allowing specific features (such as seal positions, guide channel orientations, and sash profile arrangements) to be configured locally to meet specific application requirements. This enables customization at the assembly level rather than requiring different profile types.

Inventive Principle:

Principle #3Local quality

AI summary

The invention relates to a profile system for a sliding door or sliding window assembly for installation in an inclined window opening of a building, for example, a roof sliding door or roof sliding window, comprising a frame (1) with two horizontally extending frame legs (2, 3), each formed by a main profile (4), and a sash frame (5) with at least one glass pane (9), the horizontally extending sash frame legs (6, 7) and the single vertically extending sash frame leg (8) of which are each formed by a first sash profile (10). The two horizontally extending sash frame legs (6, 7) or the corresponding first sash profiles (10) are guided in guides (11) of the horizontally extending frame legs (6, 7) or the corresponding main profiles (4).
