Solution Overview

Problem

Traditional curtain guide rails require customized manufacturing for each window width, leading to inefficiencies in mass production, high costs, and potential errors in measurement and manufacturing, resulting in rework and resource wastage.

Innovation Solution

A telescopic curtain guide rail system comprising an inner rail, an outer rail, and a transmission unit with a unique winding mode that maintains the length of the conveyor belt unchanged, allowing for adjustable length without increasing the guide rail's volume, facilitating industrialized mass production.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If traditional customized curtain guide rails are manufactured for each window width, then the guide rail fits the specific window size, but the production efficiency is low and costs are high

Engineering Contradiction:
Improveguide rail fit to window sizeVSAvoidproduction efficiency
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The curtain guide rail is designed with telescopic functionality, allowing the inner rail to slide within the outer rail and be fixed at different positions. This dynamic adjustment mechanism enables a single guide rail product to adapt to various window widths, eliminating the need for customized manufacturing for each size while maintaining precise fit.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If telescopic curtain guide rail uses multiple pulleys for winding, then the guide rail can be adjusted in length, but the volume of the guide rail increases

Engineering Contradiction:
Improveadjustable lengthVSAvoidguide rail volume
Core Design Contradiction:
Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The patent extracts and eliminates the multiple pulley winding mechanism from the telescopic guide rail design. Instead, it uses a simpler sliding and fixing mechanism where the inner rail slides within the outer rail and is secured at desired positions using fixing components. This extraction of unnecessary components reduces the guide rail volume while maintaining the adjustable length capability.

AI summary

A telescopic curtain guide rail includes an inner rail, an outer rail and a transmission unit. The inner rail is embedded in the outer rail, the transmission unit includes a driving wheel connected with a motor, a driven wheel, two fixed pulleys and a conveyor belt. The driving wheel and the driven wheel are located at two ends of the curtain guide rail, the two fixed pulleys are respectively located at other ends of the inner rail and outer rail. The driving wheel and one fixed pulley are located at two ends of the inner rail or outer rail, the conveyor belt is wound on the driving wheel, the driven wheel and the two fixed pulleys. A telescopic operation of the curtain guide rail can change positions of the two fixed pulleys simultaneously, and the curtain guide rail is simple to use and has a small occupied area.
