Solution Overview

Problem

Existing window constructions for mobile homes and motorhomes face issues with obstacles on the exterior due to separate opening mechanisms for insect screens and roller blinds, leading to incorrect operation and reduced robustness.

Innovation Solution

A window construction featuring a main surface with an integrated frame structure, where a window pane and insect screen are movably arranged using guide rails, and a closure element is pivotally arranged on the frame to prevent external opening, enhancing operability and robustness. The insect screen is designed as a perforated plate with a surrounding frame and recessed grip, and the frame structure is U-shaped for sealing, with guide rails arranged in pairs for stability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If separate opening mechanisms are provided for insect screen and roller blind, then the window can be operated independently, but obstacles are created on the exterior and operation becomes complex

Engineering Contradiction:
ImproveIndependent operation capabilityVSAvoidNumber of separate mechanisms
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines the opening mechanisms for the window pane, insect screen, and roller blind into a single integrated mechanism. This unified approach eliminates multiple separate controls on the exterior, reducing complexity while maintaining the ability to operate each component independently through the shared mechanism.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The single opening mechanism is designed to perform multiple functions: it can open the window pane, the insect screen, and the roller blind. This multi-functional design eliminates the need for separate mechanisms for each component, reducing exterior obstacles while preserving independent operation capability.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Ease of operation

If hinged windows with separate mechanisms are used, then ventilation is enabled, but robustness is reduced and exterior obstacles are created

Engineering Contradiction:
ImproveVentilation functionalityVSAvoidStructural robustness
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent merges the hinged window mechanism with the insect screen and roller blind into a single integrated assembly. This combination improves robustness by eliminating separate mounting points and mechanisms, while the integrated design maintains easy operation for ventilation through a single control point.

Inventive Principle:
Principle #5Merging (Combining)

3Adaptability or versatility

If multiple movable components are arranged in the frame, then functionality is enhanced, but the risk of incorrect operation increases

Engineering Contradiction:
ImproveMulti-component functionalityVSAvoidOperation accuracy
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent combines multiple movable components (window pane, insect screen, roller blind) into a single integrated mechanism with unified control. This ensures that all components operate together correctly, eliminating the risk of incorrect operation that arises from having separate mechanisms for each component.

Inventive Principle:
Principle #5Merging (Combining)
