Solution Overview

Problem

Existing curtain manufacturing methods face challenges in achieving adjustable longitudinal sizes for mass production, as they require precise measurements and are costly due to complex structures, limiting their practical application and flexibility.

Innovation Solution

A curtain design featuring an upper and lower curtain piece with a modified lateral flexible splicing assembly that includes multiple splicing positions, allowing for adjustable longitudinal sizes without precise measurement requirements, using planar, strip-shaped, or block-shaped splicing structures, and incorporating alignment strips for improved alignment and reduced lateral resilience during closure.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a long fabric is produced and rolled into a roll structure for storage and transportation, then storage and transportation are facilitated, but the curtain cannot be mass-produced in the factory and requires custom measurement for each order

Engineering Contradiction:

Improvestorage and transportationVSAvoidmass production capability

Core Design Contradiction:

Ease of manufactureVSProductivity

Solution Approach 1:

The curtain is divided into an upper curtain piece and a lower curtain piece that can be separately manufactured and then spliced together. This segmentation enables the curtain to be produced in standardized modules at the factory, facilitating mass production while maintaining the flexibility to accommodate different lengths through splicing multiple modules.

Inventive Principle:

Principle #1Segmentation

2Productivity

If a lifting curtain frame is manufactured in the factory with a cover plate structure, then mass production and application can be achieved, but the structure becomes complicated and the cost increases

Engineering Contradiction:

Improvemass production capabilityVSAvoidcurtain frame structure

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The invention removes the complex lifting curtain frame structure and cover plate from the design. Instead, it uses a simple splicing structure where the upper and lower curtain pieces are directly connected through a lateral flexible splicing assembly, achieving mass production capability without the need for complicated frames or cover plates.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

Rather than using a rigid frame structure to support the curtain, the invention inverts the approach by making the curtain fabric itself the structural element through the splicing assembly, eliminating the need for separate support frames and cover plates.

Inventive Principle:

Principle #13The other way round (Inversion)

3Productivity

If a rolling-up lifting curtain is manufactured in the factory, then mass production and application can be achieved, but it is difficult to match conventional high-grade curtain cloth and is unsuitable for formal occasions

Engineering Contradiction:

Improvemass production capabilityVSAvoidcompatibility with high-grade curtain cloth

Core Design Contradiction:

ProductivityVSAdaptability or versatility

Solution Approach 1:

The lateral flexible splicing assembly is designed to be universally compatible with various types of curtain fabrics, including conventional high-grade curtain cloth. The splicing mechanism works with different fabric types and styles, allowing mass-produced curtains to maintain aesthetic appeal and suitability for formal occasions while enabling standardized manufacturing.

Inventive Principle:

Principle #6Universality (Multi-functionality)

4Ease of operation

If the curtain structure includes detachable splicing for easy disassembly and cleaning, then maintenance becomes easier, but the manufacturing method continues to require custom measurement and cannot achieve mass production

Engineering Contradiction:

Improvedisassembly and cleaningVSAvoidmass production capability

Core Design Contradiction:

Ease of operationVSProductivity

Solution Approach 1:

The upper and lower curtain pieces are pre-spliced together at the factory using the lateral flexible splicing assembly during mass production. This preliminary action allows standardized manufacturing while maintaining the detachable feature for easy disassembly and cleaning, as the splicing can be easily undone and reconfigured after production.

Inventive Principle:

Principle #10Preliminary action

AI summary

This invention relates to a curtain with an adjustable longitudinal size and a manufacturing method thereof. The curtain includes an upper curtain piece and a lower curtain piece, and the upper curtain piece is detachably spliced with the lower curtain piece through a lateral flexible splicing assembly. The lateral flexible splicing assembly includes a first splicing part fixed at the upper curtain piece, and a second splicing part fixed at the lower curtain piece and cooperating with the first splicing part to detachably splice the upper curtain piece and the lower curtain piece. One of the first splicing part and the second splicing part is provided with a plurality of splicing positions, and the other one of the first splicing part and the second splicing part bonds a selected one of the splicing positions so as to splice the curtain with different longitudinal sizes.
