Invisible Sill Thermally Broken Window Profile

Solution Overview

Problem

Conventional methods for positioning sliding windows and doors in frames often result in aesthetic issues and tripping hazards due to misaligned protrusions, complicating the arrangement without impairing the structure.

Innovation Solution

The use of an L-shaped profiled portion with a pad and an intermediate element that fits within frame parts, allowing the L-shaped portion to protrude and receive seals, while the intermediate element extends through openings between frame parts, with connectors made of different materials for thermal resistance and visibility of frame parts.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If conventional methods are used to position sliding windows and doors in frames, then the structure can be arranged, but aesthetic appeal deteriorates and tripping hazards are created due to misaligned protrusions

Engineering Contradiction:

Core Design Contradiction:

ShapeVSDevice complexity

Solution Approach 1:

The positioning system is divided into separate components: an L-shaped profiled portion that receives the panel, an intermediate element that extends through frame openings, and a pad that fits into the frame. This segmentation allows each component to be optimized independently for both aesthetics and functionality, eliminating the need for complex integrated structures.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The intermediate element acts as a mediator between the L-shaped profiled portion and the pad. It extends through the opening between frame parts, providing a connecting structure that simplifies the overall arrangement while maintaining proper alignment and reducing complexity.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If the L-shaped profiled portion protrudes from the frame to receive seals, then sealing function is improved, but tripping hazards are created

Engineering Contradiction:

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The L-shaped profiled portion is nested within the frame structure, with only the necessary sealing portions protruding. The intermediate element and pad are nested within the opening and frame respectively, creating a compact configuration that maintains sealing functionality while minimizing protrusions that could cause tripping hazards.

Inventive Principle:

Principle #7Nested doll (Nesting)

3Loss of energy

If connectors made of different materials are used for thermal resistance, then energy efficiency is improved, but device complexity increases

Engineering Contradiction:

Core Design Contradiction:

Loss of energyVSDevice complexity

Solution Approach 1:

The connectors are constructed from composite materials with different thermal properties. Specifically, the L-shaped profiled portion, intermediate element, and pad are made of different materials to create thermal breaks that reduce energy loss through the frame structure, while the composite construction is integrated into the design rather than added as separate complex components.

Inventive Principle:

Principle #40Composite materials

AI summary

There is included an intermediate element including one or more, but not necessarily limited to, an L-shaped profiled portion configured to receive a part of a panel of a door or window, a pad configured to be fit into at least one frame part and comprising a support strip groove, and an intermediate element extended from the L-shaped portion to the pad.
