Solution Overview

Problem

Conventional curtain rods provide a poor light-shading effect, leading to negative impacts on sleep due to light leakage.

Innovation Solution

A full light-shading curtain rod with a corner structure at one end to guide the curtain for closer fitting with the wall, combined with a screen curtain hanging rod for light adjustment and decorative purposes, and featuring detachable and fixed connections for adaptability and ease of replacement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If a conventional curtain rod is used, then the structure is simple, but the light shading effect is poor due to light leakage at the sides

Engineering Contradiction:
Improvelight shading effectVSAvoidcurtain rod structure
Core Design Contradiction:
Illumination intensityVSDevice complexity

Solution Approach 1:

The curtain rod system is divided into multiple functional components: a main curtain rod, side guide structures at each end, and mounting brackets. This segmentation allows each component to perform its specific function - the main rod supports the curtain while the side guides direct the curtain edges to fit tightly against the wall, eliminating light leakage without requiring complete redesign of the entire system

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Side guide structures serve as intermediary elements between the main curtain rod and the wall. These guides mediate the curtain's position by providing a physical constraint that directs the curtain edges to follow a path closer to the wall, thereby blocking light leakage without requiring the curtain itself to be modified

Inventive Principle:
Principle #24Intermediary (Mediator)

2Illumination intensity

If the curtain is pulled to achieve light shading, then the operation is simple, but light leakage occurs at the sides reducing effectiveness

Engineering Contradiction:
Improvelight shading effectVSAvoidcurtain operation
Core Design Contradiction:
Illumination intensityVSEase of operation

Solution Approach 1:

The side guide structures are designed to automatically guide the curtain edges to fit against the wall through the natural motion of pulling the curtain. The guides create a physical constraint that self-corrects the curtain position during operation, eliminating the need for additional manual adjustment mechanisms while maintaining ease of operation

Inventive Principle:
Principle #25Self-service

3Adaptability or versatility

If a screen curtain hanging rod is added for light adjustment, then the adaptability and light control improve, but the device complexity increases

Engineering Contradiction:
Improvelight adjustment capabilityVSAvoidcurtain rod system
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The curtain rod system is designed with universal mounting brackets and standardized connection interfaces that can accommodate both the main curtain rod and the optional screen curtain hanging rod. This multi-functionality allows the same basic structure to support different curtain configurations and light control needs without requiring entirely separate mounting systems

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