Solution Overview

Problem

Conventional window sliding mechanisms require a large space for force transmission due to the use of link mechanisms, which is inefficient in terms of space utilization.

Innovation Solution

The apparatus employs a rotary member, drive member, fixation guide, and wire system to move a sliding window plate between insertion, extraction, and open positions, converting rotational force into linear motion within a compact space, reducing the required transmission path length.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a link mechanism (L-shaped link lever, connection rod) is used for force transmission, then the sliding window can be moved between positions, but a large space is required for the transmission path

Engineering Contradiction:

Improvewindow sliding operationVSAvoidspace for force transmission path

Core Design Contradiction:

Ease of operationVSVolume of moving object

Solution Approach 1:

The patent replaces the conventional link mechanism (L-shaped link lever and connection rod) with a wire rope mechanism. The wire rope is wound around a rotary member, and when the rotary member rotates, the wire rope pulls the sliding window directly, eliminating the need for complex linkages and reducing the space required for force transmission.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

Instead of using a push-based link mechanism where force is transmitted through sequential link displacements, the patent uses a pull-based wire rope mechanism. The wire rope is pulled by the rotary member to directly move the sliding window, inverting the traditional force transmission approach and achieving more compact dimensions.

Inventive Principle:

Principle #13The other way round (Inversion)

2Force

If a link mechanism is used, then force transmission is achieved, but the device complexity increases due to multiple links and connection components

Engineering Contradiction:

Improveforce transmissionVSAvoidtransmission mechanism complexity

Core Design Contradiction:

ForceVSDevice complexity

Solution Approach 1:

The patent extracts and removes the intermediate link components (L-shaped link lever, connection rod) from the force transmission system. Only the essential elements remain: the rotary member, wire rope, and pulley. This extraction simplifies the overall mechanism while maintaining effective force transmission from the operation force to the sliding window.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The wire rope serves multiple functions: it transmits force from the rotary member to the sliding window, guides the motion path, and works with the pulley to change force direction. This multi-functionality reduces the number of separate components needed, thereby reducing device complexity while maintaining effective force transmission.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

An apparatus for window used for moving a sliding window plate between an insertion position to be inserted into an opening portion of a fixed window plate, an extraction position to be extracted from the opening portion, and an open position to be shifted in a slide direction from the extraction position and to uncover the opening portion, includes a rotary member rotatably supported with respect to the sliding window plate; a drive member moved in a predetermined direction with respect to the sliding window plate; a fixation guide configured to convert a movement of the drive member in the predetermined direction with respect to the sliding window plate into a movement of the sliding window plate in an extraction/insertion direction with respect to the fixed window plate; and a wire configured to pull and move the drive member in the predetermined direction.
