Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vertical curtain structures require multiple slide rails and rail rods, increasing the size and volume of the support base, leading to higher manufacturing costs and assembly difficulties.
Innovation Solution
The hanging blinds system features an upper track with parallel first and second tracks, each with sliding slots and openings, and sliders with guiding grooves and positioning blocks, allowing for adjustable length and even distribution of weight, enabling smoother operation and stability through pulley mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple slide rails and rail rods are used in conventional vertical curtain structures, then the curtains can be properly supported and operated, but the size and volume of the support base increases, leading to higher manufacturing costs and assembly difficulties
Solution Approach 1:
The patent combines multiple rail rods into a single integrated upper track structure with parallel sliding slots. Instead of using separate slide rails for each rail rod, the invention integrates multiple curtain panels to share a common support structure, thereby reducing the overall number of components while maintaining proper support and operation for each curtain panel.
Solution Approach 2:
The upper track structure serves multiple functions simultaneously: it supports multiple curtain panels, provides sliding slots for smooth operation, incorporates pulley mechanisms for easy control, and includes positioning blocks for stable positioning. This multi-functional design eliminates the need for separate specialized components for each function.
2Reliability
If multiple slide rails and rail rods are used in conventional vertical curtain structures, then the curtains can be properly supported, but the manufacturing cost increases due to more components
Solution Approach 1:
By merging multiple rail rods into a single upper track assembly with integrated sliding slots and positioning blocks, the invention reduces the total number of parts that need to be manufactured, stored, and assembled. This consolidation directly lowers manufacturing costs while maintaining reliable curtain support through the integrated structure.
3Reliability
If multiple slide rails and rail rods are used in conventional vertical curtain structures, then the curtains can be properly supported, but the assembly and installation difficulty increases
Solution Approach 1:
The integration of multiple rail rods into a single upper track structure with pre-configured sliding slots and positioning blocks significantly simplifies assembly and installation. Installers no longer need to individually position and align multiple separate slide rails and rail rods, reducing installation time and complexity while ensuring proper curtain support.
Solution Approach 2:
The upper track structure is designed with sliding slots and positioning blocks pre-configured in the correct positions during manufacturing. This preliminary arrangement of components eliminates the need for complex field adjustments and alignments during installation, making the assembly process much easier while ensuring reliable curtain support.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design allows for adjustable curtain length, improved smoothness of slider travel, and reduced deformation of the upper track, while simplifying installation and reducing manufacturing costs by minimizing the number of required components.
Implementation Method 1
Each slider 20 other than the last slider 20 on the second track 12 has at least two pulleys 26 slidably mounted in the sliding slots 111, 121 of the first or second tracks 11, 12

AI summary
Hanging blinds includes an upper track and a plurality of sliders. The upper track has at least a first track and a second track respectively having a sliding slot. Each of sliders has a guiding groove and a positioning groove. A sliding block is disposed at an end of the positioning groove and enabling the slider to be mounted onto a guiding groove of an adjacent slider. Each slider is mounted onto one sliding slot of the first and second tracks. A last slider on the second track has at least two positioning blocks locking with an end of the second track. The sliders other than the last slider each has a pulley. The last slider on the first track has a crossing pulley slidably mounted in the sliding slot of the second track. The crossing pulley is disposed before a pulley of a first slider on the second track.
