Solution Overview

Problem

The processing of hose sections in existing technologies is intermittent, leading to reduced output and quality due to frequent re-alignment and handling, and requires significant effort for device conversion when changing hose lengths or processing steps, with difficulty in determining and reproducing quality parameters.

Innovation Solution

A device with two linear motor circuits and processing units that allows continuous processing of hose sections without re-orientation, using a system where linear motor carriages can mesh like gears to perform operations during transport, with precise alignment and adaptable software settings for different dimensions, and includes clamping units for secure attachment and cutting of hose sections.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If hose sections are processed in intermittent steps with frequent re-alignment and handling, then processing flexibility is maintained, but productivity and quality deteriorate due to reduced output and handling-induced errors

Engineering Contradiction:
Improveoutput of processed hose sections per unit of timeVSAvoidhandling and re-alignment effort
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The patent implements continuous transport of hose sections through a processing line with multiple processing units operating simultaneously on continuously moving hose sections. The linear motor carriage units transport assemblies through processing sections without interruption, eliminating intermittent stopping and re-alignment operations, thereby maintaining continuous productive action throughout the system.

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

The system employs dynamically adjustable linear motor carriage units that can adapt their position and speed during continuous transport. The processing units are positioned on moving carriages that can adjust their relative positions to accommodate different processing requirements while maintaining continuous motion, enabling flexible processing without interrupting the flow.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If hose sections are released from original orientation and re-clamped for further processing, then different processing steps can be performed, but manufacturing precision deteriorates due to new recording and alignment requirements

Engineering Contradiction:
Improveprocessing step flexibilityVSAvoidalignment precision of hose sections
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The processing system is divided into multiple independent processing units, each capable of performing specific operations on the hose sections. The linear motor carriage units are segmented into separate controllable modules that can be positioned independently along the transport line, allowing different processing operations to be applied at different locations without disrupting the overall continuous flow and orientation.

Inventive Principle:
Principle #1Segmentation

3Adaptability or versatility

If device configuration is changed to adapt to different hose lengths or processing steps, then versatility is improved, but device complexity and conversion effort increase significantly

Engineering Contradiction:
Improveadaptability to different hose dimensions and processing stepsVSAvoiddevice conversion effort
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The linear motor carriage units are designed as universal, multi-functional modules that can perform multiple processing operations. Each carriage unit can be equipped with different processing tools or configurations through software control without requiring physical reconfiguration of the entire device. The same hardware platform supports various hose dimensions and processing steps, eliminating the need for dedicated equipment for each application.

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

Solution Approach 2:

The system achieves adaptability to different hose lengths and dimensions by changing operational parameters through software control rather than physical reconfiguration. The linear motor carriage units can adjust their speed, position, and processing parameters digitally to accommodate different product specifications, allowing quick changeovers without mechanical modifications to the device structure.

Inventive Principle:
Principle #35Parameter changes
