Solution Overview

Problem

Current retractable sliding guides for shielding systems, such as mosquito nets and curtains, fail to provide optimal tensioning and are not adaptable to curved or non-linear profiles, leading to suboptimal sealing and aesthetic issues, with existing solutions also being inefficient in material use and labor-intensive to install.

Innovation Solution

A retractable sliding guide with a tensioning system comprising modular components connected by hinges, featuring a curvilinear tensioning element that maintains cloth tension through resilient biasing, allowing adaptation to various profiles and ensuring uniform anchoring even under wind action.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional sliding guides are used for shielding systems, then the structure is simple and easy to manufacture, but the cloth tensioning is not optimal and sealing is poor

Engineering Contradiction:
Improvesealing performanceVSAvoidguide structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The sliding guide is divided into multiple modular sections that can be independently assembled and configured. Each module contains integrated tensioning elements and guiding components, allowing the system to achieve optimal tensioning and sealing while maintaining manufacturing simplicity through standardized modular units.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent combines the guiding function and tensioning function into a single integrated sliding guide structure. The guide rails incorporate built-in tensioning mechanisms that work simultaneously with the guiding function, eliminating the need for separate tensioning devices and achieving both simple construction and optimal sealing performance.

Inventive Principle:
Principle #5Merging (Combining)

2Adaptability or versatility

If rigid straight guides are used, then the manufacturing and installation is straightforward, but the system cannot adapt to curved or non-linear profiles

Engineering Contradiction:
Improveprofile adaptabilityVSAvoidinstallation complexity
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The sliding guide employs adjustable and flexible components that can adapt to different profile configurations. The modular design allows the guide to be configured for straight, curved, or non-linear trajectories, while standardized connection elements maintain ease of installation across different profile types.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The guide system incorporates adjustable parameters such as module orientation, connection angles, and tensioning forces that can be modified to accommodate various profile shapes. This flexibility allows the same basic modular components to adapt to curved or non-linear profiles without increasing manufacturing or installation complexity.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If cushioning systems with separate tabs are used, then the impact protection is effective, but the material waste and labor for installation increases

Engineering Contradiction:
Improveimpact cushioningVSAvoidinstallation efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The cushioning function is integrated directly into the sliding guide structure through built-in elastic elements and shock-absorbing features. This eliminates the need for separate cushioning tabs, reducing both material waste and installation labor while maintaining effective impact protection.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The sliding guide incorporates self-cushioning features that automatically absorb impact forces during operation. The elastic elements within the guide structure provide automatic cushioning without requiring additional components or complex installation procedures, improving installation efficiency while maintaining reliability.

Inventive Principle:
Principle #25Self-service

4Shape

If the guide structure is exposed, then the functionality is straightforward, but the aesthetic appearance is compromised

Engineering Contradiction:
Improveaesthetic appearanceVSAvoidguide structure complexity
Core Design Contradiction:
ShapeVSDevice complexity

Solution Approach 1:

The sliding guide is designed to be nested within or concealed by the shielding cloth and frame structure. The guide components are positioned and configured to be hidden from view during normal operation, allowing the functional elements to remain accessible while the aesthetic appearance is maintained through strategic placement and integration with the overall system design.

Inventive Principle:
Principle #7Nested doll (Nesting)
