Solution Overview

Problem

Existing window sill support brackets require different designs for various installation situations, leading to inefficiencies and increased complexity in installation.

Innovation Solution

A support bracket system with a mounting profile featuring pivotally connected profile segments and a fixing profile that can be angled or straight, allowing adaptation to different facade constructions, combined with a fastening profile for secure attachment, and optionally including a support profile and hook section for enhanced stability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If different support brackets are designed for different installation situations, then the reliability of window sill fixation is improved, but the device complexity and variety of components increases

Engineering Contradiction:
Improvewindow sill fixation reliabilityVSAvoidsupport bracket variety
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The mounting profile is designed with multiple functional capabilities: it can be attached to different facade types (with or without thermal insulation), accommodate different window sill positions, and provide both structural support and thermal insulation functions. This single multi-functional component replaces the need for multiple specialized brackets, resolving the contradiction between reliability and complexity

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

Solution Approach 2:

The support bracket system is divided into separable components: a mounting profile with integrated insulation, a fixing profile, and connection elements. This segmentation allows the mounting profile to be universally adapted to different installation situations through configuration changes rather than requiring completely different bracket designs, reducing component variety while maintaining fixation reliability

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If multiple different support brackets are required for different installation situations, then the adaptability to various facade constructions is improved, but the ease of operation during installation deteriorates

Engineering Contradiction:
Improvefacade construction adaptabilityVSAvoidinstallation simplicity
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The mounting profile serves as a universal component that can be installed on various facade types including those with external thermal insulation composite systems and those without. The same basic profile design adapts to different situations through its configurable features, eliminating the need for installers to select from multiple different bracket types and simplifying the installation process

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

Solution Approach 2:

The mounting profile incorporates adjustable and configurable features that allow it to dynamically adapt to different installation requirements. The profile can be configured in different orientations and positions to suit various facade constructions, providing adaptability without requiring multiple static bracket designs, thus maintaining installation simplicity

Inventive Principle:
Principle #15Dynamics
