Solution Overview

Problem

In spun yarn take-up systems, the need for long hoses to supply compressed fluid to movable yarn threading robots leads to reduced hose lifespan and potential interference with other components, affecting efficiency and cost.

Innovation Solution

The system divides the compressed fluid supply passage into system-side and robot-side pipes, with detachable connecting members, allowing the robot-side pipe to be shorter and eliminating the need for a long hose, and includes a controller to manage fluid supply and waste, reducing unnecessary consumption and costs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a long hose is used to supply compressed fluid to the movable yarn threading robot, then the robot can reach all spun yarn take-up apparatuses, but the hose has short life and may interfere with other members

Engineering Contradiction:
Improverobot mobilityVSAvoidhose lifespan
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The supply passage is segmented into a system-side supply pipe (fixed infrastructure) and a robot-side supply pipe (movable with robot). The robot-side supply pipe is connected via a detachable connecting member, allowing it to be a short, manageable length rather than a long continuous hose. This segmentation resolves the contradiction by enabling robot mobility through the detachable connection while avoiding the problems of long hoses.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If a long hose is used to supply compressed fluid to the movable yarn threading robot, then the robot can reach all spun yarn take-up apparatuses, but the hose may interfere with another member

Engineering Contradiction:
Improverobot mobilityVSAvoidhose interference
Core Design Contradiction:
Adaptability or versatilityVSObject-generated harmful factors

Solution Approach 1:

By dividing the supply passage into fixed system-side pipe and movable robot-side pipe with a detachable connection, the robot-side pipe remains short and controlled. This prevents the hose from extending across the entire workspace and interfering with other members, while still allowing the robot to move to different positions.

Inventive Principle:
Principle #1Segmentation

3Length of moving object

If the supply passage is divided into system-side and robot-side pipes with detachable connecting members, then the robot-side pipe can be shorter, but the system complexity increases

Engineering Contradiction:
Improverobot-side pipe lengthVSAvoidconnection system complexity
Core Design Contradiction:
Length of moving objectVSDevice complexity

Solution Approach 1:

The system transitions from a static long hose to a dynamic detachable connection system. The robot-side supply pipe can be connected and disconnected as needed, allowing it to be short during operation while maintaining flexibility. This dynamic approach reduces the effective length of the movable pipe without requiring a permanently complex installation.

Inventive Principle:
Principle #15Dynamics

4Length of moving object

If a detachable connecting member is used to connect system-side and robot-side supply pipes, then the robot-side pipe can be short, but the attachment and detachment operation becomes more complex

Engineering Contradiction:
Improverobot-side pipe lengthVSAvoidconnection operation ease
Core Design Contradiction:
Length of moving objectVSEase of operation

Solution Approach 1:

The detachable connecting member acts as an intermediary component that simplifies the connection operation. By providing a standardized interface between the system-side and robot-side pipes, it enables quick attachment and detachment without requiring complex alignment or multiple fastening steps, thus maintaining ease of operation despite the modular design.

Inventive Principle:
Principle #24Intermediary (Mediator)
