Solution Overview

Problem

Conventional sliding window systems face challenges in achieving excellent soundproof, airtight, watertight, heat insulation, and wind pressure resistance due to limitations in sealing methods, particularly with heavy-weighted components and non-uniform sealing principles, which hinder smooth vertical movement and effective sealing, especially in large-sized windows.

Innovation Solution

A sliding window system with an aluminum alloy sash structure, incorporating a moving window installation structure that includes a window frame with thermal breaks, a roller device, and a horizontal-moving device, which allows for vertical sliding without applying a vertical reaction force to the roller, ensuring smooth movement and enhanced sealing by using thermal breaks and a vertical sliding unit to prevent vertical component forces, and a compression unit to facilitate horizontal movement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a conventional sealing method using windbreak hair or rubber is used, then the sealing performance is improved, but the sealing member deforms or wears out over time, making it difficult to maintain constant performance

Engineering Contradiction:
Improvesealing performanceVSAvoidservice life of sealing member
Core Design Contradiction:
ReliabilityVSDuration of action of stationary object

Solution Approach 1:

The patent changes the sealing mechanism from elastic deformation of rubber to mechanical compression through a lifting mechanism. The sash is lifted vertically to compress the sealing member against the frame, transforming the sealing parameter from material elasticity to mechanical force application, which prevents deformation and wear of the sealing member.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent replaces the conventional elastic sealing mechanism with a mechanical lifting system. Instead of relying on the elastic properties of rubber seals, the system uses a roller and guide rail mechanism to physically lift the sash, creating compression through controlled movement rather than material deformation.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If a lift and sliding type structure is used to lift the moving window, then the sealing performance is improved, but a vertical reaction force is applied between the rail and roller, making it difficult to slide smoothly

Engineering Contradiction:
Improvesealing performanceVSAvoidsliding smoothness
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent segments the forces acting on the roller by introducing a guide rail that constrains the roller's movement path. The guide rail separates the vertical lifting function from the horizontal sliding function, allowing the roller to lift the sash vertically while preventing it from applying vertical reaction forces during horizontal sliding motion.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The guide rail acts as an intermediary element between the roller and the sash. It mediates the force transmission by providing a constrained path for the roller, allowing vertical lifting forces to be applied during sealing while preventing vertical reaction forces during sliding, thus resolving the conflict between sealing and smooth operation.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Area of moving object

If the moving window is heavy (large-sized window), then the window size and functionality are improved, but the weight makes it difficult to slide smoothly with conventional roller support

Engineering Contradiction:
Improvewindow sizeVSAvoidsliding ease
Core Design Contradiction:
Area of moving objectVSEase of operation

Solution Approach 1:

The patent extracts the weight-bearing function from the sliding mechanism by introducing a lifting mechanism that independently supports the window's weight. The roller is separated from its dual role of supporting weight and enabling sliding, with the lifting mechanism handling weight support and the guide rail handling sliding motion, allowing large heavy windows to slide smoothly.

Inventive Principle:
Principle #2Taking out (Extraction)

4Strength

If aluminum alloy sash structure is used, then the structural strength is improved, but heat insulation performance deteriorates due to high thermal conductivity

Engineering Contradiction:
Improvestructural strengthVSAvoidheat insulation performance
Core Design Contradiction:
StrengthVSLoss of energy

Solution Approach 1:

The patent employs composite material construction with aluminum alloy sash structures combined with thermal break components. The aluminum alloy provides structural strength while the thermal break material (typically plastic or composite) interrupts heat conduction paths, creating a composite system that achieves both structural integrity and heat insulation performance.

Inventive Principle:
Principle #40Composite materials
