Cloth positioner for continuous processing

Solution Overview

Problem

In continuous processing of cloth materials, frequent re-positioning on different holding pattern dies leads to offset errors, resulting in irregular outer profiles and reduced processing precision and efficiency, which hinders automatic processing and increases resource waste.

Innovation Solution

A cloth positioner with a processing base, alignment plate, and figure position abutment pin pieces that allow for repeated use across various processing procedures, featuring high-temperature-resistant materials and adjustable clamping mechanisms to maintain precise positioning without repositioning errors.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If cloth is re-positioned on different holding pattern dies for each processing procedure, then the cloth can be processed through multiple procedures, but offset errors accumulate and processing precision deteriorates

Engineering Contradiction:

Improvecontinuous processing capabilityVSAvoidpositioning accuracy

Core Design Contradiction:

ProductivityVSManufacturing precision

Solution Approach 1:

The patent applies universality by designing a single holding pattern die that can be reused across multiple processing procedures (ironing, thermo-compression, printing, dyeing, cutting). The die incorporates multiple pin pieces with different clamping forces that can be selected based on different cloth types and processing requirements, making one die serve multiple functions and eliminating the need to switch between different dies for each procedure.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent applies preliminary action by pre-positioning the cloth on the holding pattern die using pin pieces before processing begins. The pin pieces are arranged to clamp the cloth at specific locations in advance, establishing a reference position that is maintained throughout subsequent processing procedures. This preliminary positioning prevents offset errors from accumulating during the processing sequence.

Inventive Principle:

Principle #10Preliminary action

2Adaptability or versatility

If multiple different holding pattern dies are used for different processing procedures, then various processing requirements can be met, but fixture costs and resource waste increase

Engineering Contradiction:

Improveprocessing procedure compatibilityVSAvoidresource consumption

Core Design Contradiction:

Adaptability or versatilityVSLoss of substance

Solution Approach 1:

The patent applies universality by designing a single holding pattern die that can be reused across multiple processing procedures (ironing, thermo-compression, printing, dyeing, cutting). The die incorporates multiple pin pieces with different clamping forces that can be selected based on different cloth types and processing requirements, making one die serve multiple functions and eliminating the need to switch between different dies for each procedure.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent applies discarding and recovering by using removable pin pieces that can be taken out and replaced. Instead of discarding the entire holding pattern die after each use, the pin pieces are recovered and reused in subsequent processing procedures. This reduces resource consumption and waste while maintaining adaptability to different processing requirements.

Inventive Principle:

Principle #34Discarding and recovering

3Productivity

If cloth is re-positioned multiple times across different processing procedures, then complete processing can be achieved, but time consumption and production efficiency worsen

Engineering Contradiction:

Improveproduction efficiencyVSAvoidre-positioning time

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by pre-positioning the cloth on the holding pattern die using pin pieces before processing begins. The pin pieces are arranged to clamp the cloth at specific locations in advance, establishing a reference position that is maintained throughout subsequent processing procedures. This preliminary positioning prevents offset errors from accumulating during the processing sequence.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent applies continuity of useful action by enabling the cloth to remain on the same holding pattern die throughout the entire processing sequence without removal or re-positioning. The processing procedures are performed continuously on the cloth while it remains clamped by the pin pieces, eliminating idle time for re-positioning and maintaining continuous productive action throughout the manufacturing process.

Inventive Principle:

Principle #20Continuity of useful action
