Solution Overview

Problem

Existing textile smoothing methods in tunnel finishers often result in uneven drying times, leading to overheating and unnecessary energy consumption, as they are based on the most intensive drying requirements, which can extend the finishing treatment time for all clothing items regardless of their type and size.

Innovation Solution

A method and device that allow heavier, more intensive textile items to be dried in multiple passes through a single or successive tunnel finishers, while lighter items are sufficiently dried in fewer passes, using a return conveyor system and sensors to determine the number of passes needed based on type and size, and deactivating steam in subsequent passes for fully dried items.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If all textile objects are dried based on the most intensive drying requirements, then heavy items like trousers are sufficiently dried, but lighter items are overdried and processed longer than necessary

Engineering Contradiction:
Improvedrying sufficiencyVSAvoidfinishing treatment time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent applies parameter changes by varying the drying parameters (number of passes through the tunnel finisher) based on the specific characteristics of each textile object. Light items undergo one pass while heavy items undergo multiple passes, optimizing both drying sufficiency and processing time for each item type.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The system dynamically adjusts the drying process by using sensors to detect textile object characteristics and automatically determining the appropriate number of passes. This dynamic adaptation allows the system to optimize drying time for each item rather than using a fixed uniform process.

Inventive Principle:
Principle #15Dynamics

2Reliability

If all textile objects are dried based on the most intensive drying requirements, then heavy items like trousers are sufficiently dried, but unnecessary energy is consumed

Engineering Contradiction:
Improvedrying sufficiencyVSAvoidenergy consumption
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The patent applies parameter changes by varying the drying parameters (number of passes through the tunnel finisher) based on the specific characteristics of each textile object. Light items undergo one pass while heavy items undergo multiple passes, optimizing both drying sufficiency and processing time for each item type.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The system uses sensors to automatically detect textile object characteristics and self-determine the appropriate drying process without manual intervention. This self-service approach optimizes energy consumption by matching drying intensity to actual item requirements.

Inventive Principle:
Principle #25Self-service

3Ease of operation

If a single drying time is used for all textile objects, then the process is simple to operate, but it cannot accommodate different drying requirements of different items

Engineering Contradiction:
Improveprocess simplicityVSAvoiddrying requirement accommodation
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent implements feedback by using sensors to detect textile object characteristics and automatically adjusting the drying process accordingly. This closed-loop system maintains ease of operation while achieving high adaptability, as the system self-adjusts based on sensor input without requiring complex manual configuration.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system achieves universality by using a single tunnel finisher that can handle multiple drying scenarios through variable pass counts. The same equipment adapts to different drying requirements by adjusting the number of cycles, eliminating the need for multiple specialized drying chambers.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

Garments (18) are typically treated with hot steam in tunnel finishers (10) and then dried. This process smooths the garments (18). The garments (18) are usually fed into the tunnel finisher (10) unsorted. As a result, garments (18) with varying drying times must be dried in the tunnel finisher (10). To ensure all garments (18) are dried sufficiently, the drying cycle is currently determined by the garment (18) requiring the longest drying time. This leads to garments (18) that could be dried more quickly being over-dried, resulting in unnecessary energy loss.The invention provides for repeatedly drying garments (18) that are difficult to dry by transporting them through the single tunnel finisher (10) several times until the garments (18) that are difficult to dry are sufficiently dry.
