Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If automated task operation is implemented, then operator efficiency is improved, but device complexity increases

Engineering Contradiction:
Improveoperator efficiencyVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system records operator commands and machine responses as a playbook that can be replayed automatically. This copying approach allows the automated system to replicate successful operations without requiring complex real-time decision-making algorithms, thereby improving operator efficiency while keeping the system complexity manageable.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The system performs preliminary actions by recording the sequence of operator commands and machine responses during a示范 operation. This pre-recorded playbook enables automatic execution of repetitive tasks, improving productivity while the complexity is confined to the recording and playback functionality rather than complex real-time control algorithms.

Inventive Principle:
Principle #10Preliminary action

2Measurement precision

If automated task operation is implemented, then accuracy is improved, but device complexity increases

Engineering Contradiction:

Solution Approach 1:

The system incorporates feedback mechanisms where machine responses are recorded alongside operator commands. This feedback loop ensures that the automated system can accurately replicate the original operation sequence, improving operational accuracy while maintaining manageable system complexity through structured data recording and playback.

Inventive Principle:
Principle #23Feedback

3Loss of time

If recorded operation playback is implemented, then time consumption is reduced, but device complexity increases

Engineering Contradiction:

Core Design Contradiction:
Loss of timeVSDevice complexity

Solution Approach 1:

The system creates a copy of the operational sequence in the form of a recorded playbook that can be replayed automatically. This copying mechanism eliminates the need for complex real-time control algorithms while enabling rapid execution of repetitive tasks, thereby reducing time consumption with moderate system complexity.

Inventive Principle:

4Ease of operation

If electrical actuators are controlled automatically, then operator workload is reduced, but device complexity increases

Engineering Contradiction:
Improveoperator workloadVSAvoidcontrol system complexity
Core Design Contradiction:

Solution Approach 1:

The system enables self-service operation by automatically playing back recorded commands to control electrical actuators. This allows the machine to perform repetitive tasks autonomously without requiring continuous operator input, reducing operator workload while the control system complexity is limited to the playback functionality rather than complex real-time decision-making.

Inventive Principle:
Principle #25Self-service
