Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual removal process is used with two operators, then the tape and resin can be removed, but the production efficiency is low and labor costs are high

Engineering Contradiction:
Improveproduction efficiencyVSAvoidautomation level
Core Design Contradiction:
ProductivityVSExtent of automation

Solution Approach 1:

The system uses vision recognition to automatically detect tape and resin positions, and the robot autonomously performs removal operations without human intervention, making the system self-sufficient in the removal process

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical removal operations with an automated robotic system that uses vision guidance and automated cutting mechanisms, substituting human labor with automated mechanical systems

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

2Reliability

If two operators perform removal operations, then the tape and resin can be removed, but the operation speed varies and consistency is poor

Engineering Contradiction:
Improveoperation consistencyVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The vision recognition system continuously monitors and detects the position of tape and resin, providing real-time feedback to the control system to adjust the robot's cutting path and ensure consistent removal quality

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system dynamically adjusts cutting parameters such as blade position, cutting depth, and robot movement speed based on real-time vision detection data, ensuring consistent removal quality across different operations

Inventive Principle:
Principle #35Parameter changes

3Loss of time

If manual removal is used, then the process is simple, but the labor cost and time consumption are high

Engineering Contradiction:
Improvetime consumptionVSAvoidsystem complexity
Core Design Contradiction:
Loss of timeVSDevice complexity

Solution Approach 1:

The vision recognition system performs preliminary detection and positioning of tape and resin before the robot begins removal operations, pre-planning the cutting path to optimize the removal process and reduce overall time consumption

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The robot performs continuous removal operations without interruption once started, maintaining constant motion and cutting action to maximize efficiency and minimize idle time throughout the removal process

Inventive Principle:
Principle #20Continuity of useful action
