Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a working machine is equipped with autonomous traveling and operation capabilities, then productivity and versatility are improved, but device complexity increases due to the need for recognition units and control systems

Engineering Contradiction:
Improveautonomous operation capabilityVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The working machine uses its own recognition unit to detect surrounding environments and autonomously determines travel routes and operation timing without external control. The machine serves itself by processing sensor data internally to execute autonomous mowing tasks, reducing the need for complex external control systems.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical operation with automated control systems that process sensor data electronically. The recognition unit captures environmental information and the control unit automatically generates commands, substituting the operator's mechanical control with an automated electro-mechanical system.

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

2Ease of operation

If the working machine operates autonomously without an operator, then ease of operation is improved, but reliability may worsen due to potential errors in autonomous decision-making

Engineering Contradiction:
Improveautonomous operationVSAvoidoperational reliability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The recognition unit continuously monitors the surrounding environment and provides real-time feedback to the control unit. This feedback loop enables the system to detect obstacles, adjust its route, and respond to changing conditions, improving reliability through continuous environmental awareness and adaptive decision-making.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system performs preliminary actions by pre-planning travel routes and operations based on recognized environmental data before execution. The control unit anticipates potential issues and prepares appropriate responses in advance, reducing the likelihood of errors during autonomous operation.

Inventive Principle:
Principle #10Preliminary action
