Solution Overview

Problem

Conventional sliding windows are difficult to use, prone to getting stuck, and can only open up to half due to their division into two separate units, limiting their functionality and space efficiency.

Innovation Solution

The implementation of an electric drive device with a motor and guide rails allows for easy and reliable operation of the window, eliminating the need for manual handling, enabling the window to open fully and providing enhanced safety and integration with alarm systems, while maintaining a compact footprint.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual operation of sliding window is used, then device complexity is reduced, but ease of operation deteriorates and reliability worsens due to jamming and cumbersome handling

Engineering Contradiction:
Improveease of operationVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent replaces the manual mechanical operation system with an electric drive system. The electric motor (7) drives the window (2) through a drive mechanism, eliminating the need for manual handling and associated mechanical components like cranks or levers. This substitution improves ease of operation while the integrated control system manages the added complexity.

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

Solution Approach 2:

The electric drive system with motor (7) and control unit enables the window to operate autonomously without requiring manual intervention. The system can be controlled via remote control or building management system, allowing the window to serve itself in terms of opening and closing operations.

Inventive Principle:
Principle #25Self-service

2Ease of manufacture

If two-part sliding window design is used, then ease of manufacture is improved, but the window opening area that can be opened is limited to half

Engineering Contradiction:
Improveease of manufactureVSAvoidwindow opening area
Core Design Contradiction:
Ease of manufactureVSArea of moving object

Solution Approach 1:

The patent applies segmentation by dividing the window system into two parts: a stationary window portion and a movable window portion that can be completely removed from the opening. The movable window (2) slides along guide rails (3) and can be fully extracted, while the stationary portion remains in the frame. This segmentation allows more than half of the opening to be freed while maintaining manufacturing simplicity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention changes the movement dimension from partial lateral sliding to complete removal along the guide rails. The window (2) moves from a constrained sliding motion to a full extraction motion, enabling the entire window area to be opened rather than just half, effectively utilizing the vertical and lateral space for complete window removal.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Reliability

If manual handling of window is required, then device complexity is reduced, but safety deteriorates due to accidental slamming and burglary vulnerability

Engineering Contradiction:
ImprovesafetyVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces manual mechanical handling with an electric drive system controlled by a control unit. This electronic control system prevents accidental slamming by controlling the window's movement speed and position, and enhances security by enabling integration with alarm systems and remote monitoring capabilities.

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

Solution Approach 2:

The control unit receives feedback signals and can control the electric motor (7) accordingly to prevent unsafe operations. The system can detect the window's position and adjust its movement to prevent slamming, and can be integrated with alarm systems that provide feedback on window status for security purposes.

Inventive Principle:
Principle #23Feedback
