Solution Overview

Problem

Current screen apparatuses with wheel bodies or wire adjusting apparatuses on window frames suffer from track wires swinging out of the track, leading to unsmooth operation or sticking during opening and closing due to stress, and existing solutions require additional frame material preparation and complex installation.

Innovation Solution

A corner connector structure with an integrated wire adjuster in a combining groove, featuring a fixing base and wire adjusting base, which accommodates and tensions the track wire within recessed grooves of the frame materials, preventing the wire from swinging out of the track.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a wire adjuster is mounted on frame materials using pre-processed holes or grooves, then the wire adjuster can be installed, but the installation complexity increases and additional material preparation is required

Engineering Contradiction:
Improveinstallation complexityVSAvoidmaterial preparation
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The wire adjuster is integrated directly into the corner connector structure, merging two separate components (corner connector and wire adjuster) into a single unified structure. This eliminates the need for separate installation steps and material preparation, as the wire adjuster becomes an inherent part of the corner connector rather than an add-on component.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The corner connector structure is designed to perform multiple functions: it provides mechanical connection between frame members and simultaneously houses the wire adjuster mechanism. This multi-functionality reduces the overall number of components needed and simplifies installation by eliminating the need for separate wire adjuster mounting.

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

2Reliability

If the track wire is accommodated in the wire adjuster of the corner connector, then the track wire is prevented from swinging out of the track, but the corner connector structure becomes more complex

Engineering Contradiction:
Improvetrack wire stabilityVSAvoidcorner connector structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The track wire is nested within the wire adjuster mechanism that is itself integrated into the corner connector. This nested arrangement allows the wire to be contained and guided through multiple levels of structure, preventing it from swinging out while utilizing the existing corner connector geometry rather than adding external containment structures.

Inventive Principle:
Principle #7Nested doll (Nesting)

AI summary

A corner connector structure of a screen apparatus includes bodies (1), the body (1) being at least provided with a first connecting part (11) and a second connecting part (12) which is separated from the first connecting part (11) by an angle, a combining groove (13) being provided at the position of the first connecting part (11) and/or the second connecting part (12) of the body (1), and a wire adjuster (20) being provided in the combining groove (13). By means of the corner connector structure, when a screen is opened or closed and a track wire (30) swings due to stress, the track wire (30) does not swing out of the track of a frame material (201), so that the problem that when the screen is opened or closed, the screen is unsmoothly opened or closed or gets stuck easily can be solved.
