Universal Movable Seat for Vertical Curtain Blade Angle Control

Solution Overview

Problem

Conventional vertical curtains require two types of movable seats with different connecting structures for distance pieces and scissor type distance pieces, leading to increased manufacturing costs due to varied upper rail cross-sections and complex assembly processes.

Innovation Solution

A movable seat design with an open slot on one side and a hook hole at the top end allows for direct insertion of a connecting post, enabling interactive movement and compatibility with both distance pieces and scissor type distance pieces, reducing the need for multiple seat types.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If two types of movable seats with different connecting structures are used for distance pieces and scissor type distance pieces, then the vertical curtain can meet different structural requirements, but the manufacturing cost increases and the number of mold types increases

Engineering Contradiction:

Improveadaptability to different connecting structuresVSAvoidmanufacturing cost

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The movable seat is designed with a universal connecting structure that can accommodate both distance pieces and scissor type distance pieces. The connecting post with universal head features a spherical connection interface that can engage with different connection holes (through-hole or blind hole) depending on the blade type, allowing one movable seat design to serve multiple functions and eliminate the need for separate movable seat types.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If two types of movable seats with different connecting structures are used for distance pieces and scissor type distance pieces, then the vertical curtain can meet different structural requirements, but the number of mold types increases

Engineering Contradiction:

Improveadaptability to different connecting structuresVSAvoidnumber of mold types

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The movable seat is designed with a universal connecting structure that can accommodate both distance pieces and scissor type distance pieces. The connecting post with universal head features a spherical connection interface that can engage with different connection holes (through-hole or blind hole) depending on the blade type, allowing one movable seat design to serve multiple functions and eliminate the need for separate movable seat types.

3Ease of operation

If conventional connecting structures are used for distance pieces and scissor type distance pieces, then the vertical curtain can achieve interactive movement, but the assembly process becomes complex

Engineering Contradiction:

Improveinteractive movement capabilityVSAvoidassembly process

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent merges the connecting structures for distance pieces and scissor type distance pieces into a single universal connecting mechanism. The connecting post with spherical head can engage with either a through-hole or blind hole depending on the blade type, unifying what were previously separate assembly procedures into one standardized process, thereby simplifying assembly while preserving interactive movement capability.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A movable seat of a vertical curtain is disposed in an upper rail and is provided for suspending vertical curtain blades. One side of the movable seat is defined with an open slot for engaging with a distance piece, and a hook hole is formed in a top end of the movable seat. A connecting post is locked in the hook hole for connecting to a scissor type distance piece. By such arrangements, plural movable seats can be moved interactively by choosing the distance piece or the scissor type distance piece, thus controlling the angle of the vertical curtain blades.
