Solution Overview

Problem

Existing connecting elements between sills and jambs often require separate manufacturing steps and additional processing, leading to increased costs and potential leakage issues due to the need for separate sealing elements and multiple cutting dies for various shapes.

Innovation Solution

A composite connecting element formed from two materials with different properties, where the second material is integrated into the first to create an inseparable, integral whole, providing a watertight and airtight seal without separate processing or cutting dies, suitable for various frame types and materials.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If separate sealing elements and multiple cutting dies are used for various shapes, then different frame configurations can be accommodated, but manufacturing costs increase and leakage risks arise

Engineering Contradiction:
Improveadaptability to different frame configurationsVSAvoidmanufacturing cost and complexity
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent merges the connecting element and sealing element into a single integrated component. The sealing element is formed as one piece with the connecting element, eliminating the need for separate sealing components and multiple cutting dies. This integration reduces manufacturing steps, lowers costs, and eliminates leakage risks while maintaining adaptability to different frame configurations through the molded shape of the single component.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent employs composite materials to create the integrated connecting and sealing elements. Different materials with complementary properties are combined - rigid materials for structural support and flexible materials for sealing functions. This allows a single component to perform multiple functions (structural connection and weatherproof sealing) simultaneously, reducing manufacturing complexity while maintaining versatility.

Inventive Principle:
Principle #40Composite materials

2Reliability

If separate sealing elements are interposed between connecting element and jamb, then watertight and airtight seals can be achieved, but additional processing steps and potential leakage points are introduced

Engineering Contradiction:
Improvewatertight and airtight sealingVSAvoidnumber of separate components and processing steps
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The sealing function is merged directly into the connecting element structure. The sealing element is formed as an integral part of the connecting element through molding, creating a unified component that eliminates interfaces between separate sealing components and the connecting element. This integration removes potential leakage points at interfaces while maintaining effective sealing through the molded sealing geometry.

Inventive Principle:
Principle #5Merging (Combining)

3Adaptability or versatility

If multiple cutting dies are provided for different shapes, then various frame configurations can be manufactured, but manufacturing costs and production time increase

Engineering Contradiction:
Improvesupport for various frame shapesVSAvoidmanufacturing efficiency and cost
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent creates a universal molding process that can produce multiple shapes and configurations of the integrated connecting and sealing elements. A single molding system can accommodate different frame configurations by adjusting the mold cavity, eliminating the need for multiple specialized cutting dies. This multi-functional approach maintains productivity while supporting various frame shapes and configurations.

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