Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual control is used for toy aircraft, then control flexibility is improved, but operational difficulty increases and beginners easily make mistakes

Engineering Contradiction:
Improveoperational difficultyVSAvoidcontrol flexibility
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The toy aircraft automatically detects its own flight state (vertical speed, attitude angle) and adjusts its control outputs without requiring manual intervention for basic stabilization. The flight control module autonomously processes sensor data and generates control signals, allowing the aircraft to self-correct and maintain stable flight, thereby reducing operational difficulty for beginners while preserving manual control capability when needed.

Inventive Principle:
Principle #25Self-service

2Ease of operation

If automatic height control is added, then ease of operation is improved, but device complexity increases

Engineering Contradiction:
Improveease of operationVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent replaces complex mechanical control systems with electronic sensing and control. Ultrasonic sensors and attitude sensors electronically detect flight parameters, and a microcontroller electronically processes this data to automatically adjust motor speeds and control surface positions. This electronic substitution achieves automatic height control functionality while keeping the overall device complexity manageable through integrated circuit design.

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

3Measurement precision

If more sensors and computation are added, then measurement precision is improved, but device complexity increases

Engineering Contradiction:
Improvemeasurement precisionVSAvoiddevice complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The flight control module serves multiple functions: it processes data from ultrasonic sensors for height detection, processes data from attitude sensors for orientation detection, controls motor speeds for thrust regulation, and adjusts control surfaces for flight attitude. By making the flight control module universal and multi-functional, the patent achieves precise measurement and control capabilities without proportionally increasing device complexity, as one core module handles multiple tasks.

Inventive Principle:
Principle #6Universality (Multi-functionality)
