Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual control of air pump is used, then operation flexibility is maintained, but ease of operation deteriorates and automation level decreases

Engineering Contradiction:
Improveease of operationVSAvoidextent of automation
Core Design Contradiction:
Ease of operationVSExtent of automation

Solution Approach 1:

The air pump control system automatically adjusts airflow rate based on processing task information without requiring manual intervention. The controller reads processing parameters from storage, determines appropriate airflow rates, and controls the air pump accordingly, enabling the system to serve itself and eliminate manual operation steps.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical control with an automated control system that uses electronic controllers, storage devices, and communication interfaces. The controller automatically retrieves processing task information and adjusts air pump parameters based on digital data rather than manual mechanical adjustment.

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

2Reliability

If air flow rate is continuously kept high, then dust removal effectiveness is improved, but energy consumption increases

Engineering Contradiction:

Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The air pump's airflow rate is dynamically adjusted based on the specific processing task requirements. The controller determines appropriate airflow rates by reading processing parameters such as processing speed, power, and material type, allowing the system to optimize performance for each specific operation rather than maintaining a fixed high airflow rate.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes the airflow rate parameter according to different processing conditions. By storing multiple processing task information sets with corresponding optimal airflow rates and selecting based on current processing requirements, the system achieves reliable dust removal while avoiding excessive energy consumption.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If air pump is activated synchronously with laser processing, then dust removal timeliness is improved, but device complexity increases

Engineering Contradiction:
Improvedust removal timelinessVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The air pump control function is merged with the laser processing control system. The controller that manages laser processing parameters also handles air pump activation and airflow rate adjustment, synchronizing dust removal with processing operations through a unified control mechanism rather than separate independent systems.

Inventive Principle:
Principle #5Merging (Combining)

4Productivity

If manual adjustment of air pump is required, then adaptability to different processing conditions is maintained, but productivity decreases

Engineering Contradiction:

Solution Approach 1:

Optimal airflow rates for different processing conditions are predetermined and stored in the storage device along with processing task information. When a specific processing task is selected, the corresponding optimal airflow rate is automatically retrieved and applied, eliminating the need for manual adjustment while maintaining adaptability to different processing conditions.

Inventive Principle:
