Solution Overview

Problem

In a board work system with a conveying and holding device, changing the rail spacing distance can lead to interference between the conveying and holding device and the work device, particularly when performing operations from the underside of the board.

Innovation Solution

A board work system that includes a conveying and holding device with a changing mechanism for adjusting the rail spacing, a work device for performing operations on the board, a moving device to position the work device, and a control device that acquires the rail spacing distance to control the operation of the moving device and prevent interference.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the rail spacing distance is changed to accommodate different board sizes, then the adaptability of the conveying and holding device is improved, but interference may occur between the conveying and holding device and the work device

Engineering Contradiction:

Improverail spacing adjustabilityVSAvoidinterference between devices

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The control device acquires the rail spacing distance through a detection mechanism and uses this feedback information to automatically adjust the work device position via the moving device, preventing interference while maintaining adaptability to different board sizes

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system changes the operational parameters of the moving device based on the rail spacing distance. When rail spacing is adjusted, the control device modifies the position coordinates or movement range of the work device to maintain optimal clearance and prevent interference

Inventive Principle:

Principle #35Parameter changes

2Reliability

If the rail spacing distance is fixed to prevent interference, then the reliability of operation is improved, but the adaptability to different board sizes deteriorates

Engineering Contradiction:

Improveoperational reliabilityVSAvoidboard size adaptability

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The system transitions from a fixed rail spacing configuration to a dynamic adjustment mechanism where the rail spacing can be changed based on board size requirements, with automatic compensation through control system adjustment of the work device position

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The conveying and holding device is designed with universal adaptability through adjustable rail spacing, while the control device provides multi-functional operation by automatically adjusting work device parameters based on detected rail spacing, enabling the system to handle various board sizes reliably

Inventive Principle:

Principle #6Universality (Multi-functionality)
