Solution Overview

Problem

Conventional methods for collecting and recycling geotextile liners are inefficient due to contamination by dirt, rocks, and debris, and the non-uniform size and shape of the liners, making handling and recycling complicated and costly.

Innovation Solution

A geotextile rolling and collecting apparatus with a mounting plate, outer forks, linear actuators, feed drums, and drive motors that form compact rolls of geotextile liners, allowing for efficient collection and transportation, and optional integration with a cutter for uniform cutting.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If geotextile liners are collected using conventional methods, then collection is simple, but the liners become contaminated with dirt, rocks, and debris

Engineering Contradiction:
Improveease of collectionVSAvoidcontamination
Core Design Contradiction:
Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The collection system is segmented into distinct functional zones: a cutting mechanism that separates liners into uniform strips, a rolling mechanism that forms compact rolls, and a collection container. This segmentation allows each component to perform its specific function effectively, preventing contamination while maintaining ease of collection.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The rolling apparatus acts as an intermediary device between the ground where liners lie and the final collection container. By introducing this intermediate rolling mechanism, the system transforms loose contaminated liners into compact, contained rolls that are protected from further contamination during handling and transport.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of manufacture

If geotextile liners are stored in loose shreds or uncompressed bales, then storage is simple, but handling at recycling facilities is unwieldy and expensive

Engineering Contradiction:
Improveease of storageVSAvoidhandling efficiency
Core Design Contradiction:
Ease of manufactureVSEase of operation

Solution Approach 1:

The apparatus forms cylindrical rolls of geotextile liners, utilizing a curved rolling surface to transform flat, irregular liner material into compact circular forms. This curvilinear transformation creates uniform, space-efficient packages that are easy to handle, transport, and feed into recycling equipment.

Inventive Principle:
Principle #14Spheroidality (Curvature)

Solution Approach 2:

The rolling mechanism changes the physical parameters of the geotextile material by compressing it into dense rolls with consistent diameter and length. This parameter transformation from loose, voluminous material to compact, uniform rolls dramatically improves handling efficiency and reduces transportation costs.

Inventive Principle:
Principle #35Parameter changes

3Ease of operation

If geotextile liners are cut into smaller sections manually, then they become manageable, but the process is time-consuming and creates non-uniform pieces

Engineering Contradiction:
ImprovemanageabilityVSAvoidprocessing time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The system replaces manual cutting operations with a mechanical cutting mechanism that automatically slices geotextile liners into uniform strips as they are rolled up. This mechanical substitution eliminates the time-consuming manual cutting process while ensuring consistent, manageable piece sizes optimized for recycling.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The cutting action is performed preliminarily during the rolling process itself, rather than as a separate subsequent step. As the liner material is fed into the rolling mechanism, the cutter simultaneously divides it into uniform strips, preparing the material for efficient handling and recycling before it is fully rolled and collected.

Inventive Principle:
Principle #10Preliminary action

4Productivity

If geotextile liners are rolled into compact forms, then transport efficiency improves, but the rolling mechanism becomes complex

Engineering Contradiction:
Improvetransport efficiencyVSAvoidrolling mechanism complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The rolling apparatus is designed as a multi-functional attachment that can be mounted on various types of construction equipment. By making the rolling mechanism universal and adaptable to different prime movers, the system achieves compact roll formation without requiring a dedicated complex machine, thereby improving transport efficiency while controlling overall system complexity.

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

AI summary

A geotextile rolling and collecting apparatus includes a mounting plate, a pair of outer lower forks arranged laterally, a pair of outer upper forks, at least one linear actuator, at least one lower feed drum, at least one upper feed drum, and at least one first drive motor. The first drive motor is coupled to rotate the lower feed drum on a first horizontal axis and to counter-rotate the upper feed drum on a second horizontal axis. With the geotextile rolling and collecting apparatus in a collecting position, a geotextile liner grasped between the feed drums is fed by counter-rotation of the upper feed drum and the lower feed drum into a collecting volume behind the upper feed drum and the lower feed drum and between the upper forks and the lower forks to form at least one geotextile liner roll in the collecting volume.
