Solution Overview

Problem

Existing window designs with hollow chamber profiles face challenges in assembling electrical components due to high assembly effort, obscured openings, and visible recesses for photovoltaic elements, leading to complex structural requirements and maintenance issues.

Innovation Solution

The opening for electrical components is closed by a fitting part of the drive rod fitting, allowing for simplified assembly, with an accumulator for power storage, flexible components for narrow insertion, and a holding member for secure fixation, along with a feed-in module for efficient energy management.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a separate lid is mounted to close the opening in the hollow chamber profile, then the opening can be closed, but the assembly effort increases significantly

Engineering Contradiction:
Improveclosure of openingVSAvoidassembly effort
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines the lid function with the drive rod fitting into a single integrated component. The drive rod fitting itself serves as the closure element for the opening, eliminating the need for a separate lid. This merging of functions directly reduces assembly complexity while maintaining the closure capability.

Inventive Principle:
Principle #5Merging (Combining)

2Adaptability or versatility

If the hollow chamber profile is composed of multiple miter cut profiles, then structural flexibility is improved, but the opening becomes obscured and inaccessible

Engineering Contradiction:
Improvestructural flexibilityVSAvoidaccessibility of opening
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent positions the opening in a spatial location that remains accessible despite the miter cut configuration. By strategically placing the opening on a surface that is not obscured by the angular junctions of the miter cut profiles, the design maintains accessibility while preserving the structural flexibility benefits of the multi-profile construction.

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

3Adaptability or versatility

If an opening is generated in the vertical hollow chamber profile for mounting electrical components, then electrical component installation is enabled, but the structural effort increases due to precise alignment requirements

Engineering Contradiction:
Improveelectrical component mountingVSAvoidstructural effort
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent incorporates the opening for electrical component mounting as an integral feature of the hollow chamber profile during the profile manufacturing process itself. This preliminary creation of the opening eliminates the need for subsequent precise alignment and drilling operations, significantly reducing the structural effort required while enabling electrical component installation.

Inventive Principle:
Principle #10Preliminary action

4Reliability

If a lid is mounted to close the opening, then the opening is sealed, but mounting becomes impossible when a drive rod fitting portion is present in the corner region

Engineering Contradiction:
Improvesealing of openingVSAvoidmounting feasibility
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent integrates the lid function directly into the drive rod fitting component. The drive rod fitting is designed to simultaneously serve as both the actuating mechanism and the closure element for the opening. This eliminates the conflict between drive rod fitting presence and lid mounting by making the drive rod fitting itself the sealing element.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A window with a hollow chamber profile (23) of a sash (2) has an accumulator (11) arranged behind a drive mechanism (4). The accumulator (11) is flexible and can be inserted into a hollow chamber (24) through an opening (25) which is closed by the drive mechanism (4) after installation. This makes the installation of the window particularly convenient.
