Solution Overview

Problem

Existing guide devices for sliding sashes face challenges in precision installation and low error risk, particularly when adapting to different sash thicknesses and installation tolerances, often requiring high dimensional accuracy and precise assembly.

Innovation Solution

A guide device with pivotably mounted side jaws made of wear-resistant plastic, adjustable via screws, allowing for stepless adjustment of jaw distance and integration into a cast metal housing, ensuring precise adaptation to the sliding sash's thickness and tolerance position, with mirror-inverted and curved support surfaces for smooth operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If interchangeable side jaws are used to adapt to different sash thicknesses, then adaptability is improved, but assembly precision and error risk deteriorate

Engineering Contradiction:
Improveadaptability to different sash thicknessesVSAvoidassembly precision
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The side jaw is made adjustable in its position relative to the base part through pivoting mounting and adjustment screws, allowing continuous change of the jaw distance parameter to adapt to different sash thicknesses without requiring multiple interchangeable parts

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The side jaw is pivotably mounted on the base part instead of being fixed, enabling dynamic adjustment of the jaw position and orientation to accommodate variations in sash thickness and installation tolerances

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If high dimensional accuracy is required for interchangeable side jaws, then adaptability is improved, but device complexity and manufacturing cost deteriorate

Engineering Contradiction:
Improveadaptability to different sash thicknessesVSAvoidcomplexity of interchangeable parts system
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

A single side jaw design with adjustment capability serves multiple functions by accommodating different sash thicknesses and orientations, eliminating the need for multiple specialized interchangeable parts

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

Solution Approach 2:

The adjustable side jaw allows continuous parameter change in jaw distance and orientation, providing universal adaptability without requiring high-precision manufacturing of multiple discrete parts

Inventive Principle:
Principle #35Parameter changes

3Ease of manufacture

If fixed jaw distance is used in the guide device, then manufacturing simplicity is improved, but adaptability to different sash thicknesses deteriorates

Engineering Contradiction:
Improvesimplicity of guide device manufacturingVSAvoidadaptability to different sash thicknesses
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The side jaw is mounted pivotably on the base part with adjustment screws, enabling dynamic adjustment of the jaw distance to adapt to different sash thicknesses while maintaining a simple overall device structure

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The guide device is segmented into a base part and adjustable side jaws, allowing the simple base structure to remain fixed while the side jaws provide adaptability through independent adjustment

Inventive Principle:
Principle #1Segmentation

AI summary

The guide device (20) has a boundary area of the sliding wing, which encompasses in their arrangement area. The broadside of the sliding wing faces one of the two side clamp of the guide device in small distance. The distance of the side clamp (21,21') is infinitely adjustable from each other over a switching position of the guide device.
