Solution Overview

Problem

Existing foldable screen wire drawing tightness controllers are inconvenient to remove and replace due to their integration within window frames, and they face installation difficulties with extrusion molding and varying frame sizes.

Innovation Solution

A wire drawing tightness controller for foldable screens that is externally mounted on the window frame, utilizing a connecting member with detachable units and a control device featuring a gear mechanism to manage wire tension, allowing for easy assembly and disassembly without requiring frame disassembly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the wire drawing tightness controller is disposed within the window frame, then the wire tension can be controlled effectively, but the screen replacement becomes inconvenient requiring frame disassembly

Engineering Contradiction:
Improvewire tension controlVSAvoidscreen replacement convenience
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The wire drawing tightness controller is segmented into two separate connecting units: a first connecting unit integrated with the window frame and a second connecting unit integrated with the screen. This segmentation allows the screen to be detached by simply separating the two connecting units without disassembling the window frame structure, thereby maintaining wire tension control while enabling convenient screen replacement.

Inventive Principle:
Principle #1Segmentation

2Device complexity

If the shell cover is embedded in the extrusion molding window frame, then the structure is compact, but installation becomes difficult when frame size varies due to mold wear

Engineering Contradiction:
Improvestructure compactnessVSAvoidinstallation adaptability
Core Design Contradiction:
Device complexityVSEase of manufacture

Solution Approach 1:

The connecting member is designed with adjustable characteristics that allow it to adapt to different window frame sizes. Rather than relying on fixed embedded slots in extrusion molding that become problematic with wear and size variations, the connecting member can be positioned and secured flexibly on the window frame outer surface, accommodating size variations while maintaining a compact overall structure.

Inventive Principle:
Principle #15Dynamics

3Ease of operation

If the wire drawing tightness controller is externally mounted on the window frame, then the screen can be detached easily, but the structure becomes more complex

Engineering Contradiction:
Improvescreen detachment convenienceVSAvoidcontroller structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The wire drawing tightness controller merges the window frame connection function and the screen connection function into a unified structure. The first connecting unit and second connecting unit are designed as complementary components that work together as an integrated system, simplifying the overall structure compared to having separate controllers while still enabling easy screen detachment through the separation of these two units.

Inventive Principle:
Principle #5Merging (Combining)
