Solution Overview

Problem

Current flat knitting machines face challenges in automating the insertion of diverse and differently shaped inserts, such as sensors, batteries, and LEDs, into knitted fabrics during production, requiring manual intervention and increased personnel deployment.

Innovation Solution

A device comprising a magazine with interchangeable containers and a gripping system that allows for the automated insertion of various inserts of different sizes, shapes, and materials, featuring a separating mechanism, positioning devices, and monitoring systems to ensure accurate placement, which can be spatially separate from the knitting machine.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual insertion of inserts is used during knitting production, then production can continue with simple equipment, but personnel deployment increases and production efficiency decreases

Engineering Contradiction:
Improveproduction efficiencyVSAvoidequipment complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The device is divided into functionally independent modules: a magazine system with interchangeable containers for different insert types, a gripping device with adjustable grippers, a transport mechanism with positioning devices, and a control system. This modular segmentation allows each component to be optimized independently while maintaining overall system flexibility and ease of operation.

Inventive Principle:
Principle #1Segmentation

2Extent of automation

If automated insertion is implemented, then personnel requirements are reduced, but the knitting machine must stop at insertion points

Engineering Contradiction:
Improveautomation levelVSAvoidproduction interruption time
Core Design Contradiction:
Extent of automationVSLoss of time

Solution Approach 1:

Multiple types of inserts are pre-loaded into different containers within the magazine system before the knitting process begins. The control system pre-plans the insertion sequence based on the knit pattern requirements. This preliminary preparation allows inserts to be quickly exchanged and inserted during knitting without requiring machine shutdown, as all necessary components are ready in advance.

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If a fixed magazine design is used, then the structure is simple, but it cannot accommodate different types and shapes of inserts

Engineering Contradiction:
Improveinsert type flexibilityVSAvoidmagazine structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The magazine system incorporates movable and interchangeable components, including replaceable containers that can be quickly swapped to accommodate different insert types and sizes. The gripping device features adjustable grippers that can be repositioned and reconfigured. This dynamic adaptability allows the same base structure to handle diverse insert varieties without requiring complete system redesign.

Inventive Principle:
Principle #15Dynamics

4Manufacturing precision

If monitoring devices are added to check insert positioning, then insertion accuracy is improved, but device complexity increases

Engineering Contradiction:
Improveinsert placement accuracyVSAvoidmonitoring system complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

Optical sensors and monitoring devices are integrated into the magazine and gripping system to detect the presence, position, and orientation of inserts in real-time. This feedback information is continuously monitored by the control system, which automatically adjusts the positioning and gripping force to ensure accurate insert placement. The feedback loop maintains high precision without requiring complex mechanical adjustment mechanisms.

Inventive Principle:
Principle #23Feedback
