Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual operation is used for blowing-suction machine, then the machine structure can be simple, but the cleaning efficiency and self-propelled effect are poor
Solution Approach 1:
The patent implements self-service by enabling the blowing-suction machine to propel itself through the integration of an engine-driven wheel self-propelled device. The engine power is transmitted to the wheels via a transmission system, allowing the machine to move autonomously without manual pushing, thereby significantly improving cleaning efficiency while maintaining reasonable structural complexity through systematic power transmission design.
2Ease of operation
If manual operation is used, then the device complexity is low, but the operation convenience and cleaning capability are very inconvenient
Solution Approach 1:
The machine achieves self-service capability through the integration of a self-propelled device powered by the engine. The transmission system transfers power from the engine to the wheels, enabling autonomous movement that greatly enhances operation convenience. The structured power transmission design ensures that this automation is achieved without excessive structural complexity.
3Adaptability or versatility
If conventional blowing-suction machine is used, then the structure is simple, but it cannot separate garbage or walk on lawn effectively
Solution Approach 1:
The patent applies merging by combining multiple functional devices into one integrated system: the wheel self-propelled device enables movement on various surfaces including lawns, the rolling-sweeping-combing device handles different types of debris separation, and the vacuum device performs suction. This integration of multiple functions into a single machine structure achieves high adaptability and cleaning capability while managing structural complexity through systematic design.
Solution Approach 2:
The machine achieves universality through multi-functional components that can handle various cleaning scenarios. The rolling-sweeping-combing device can process different types of debris (leaves, grass, dirt), the wheel self-propelled device can traverse different terrains (lawns, pavement), and the vacuum system can collect various materials, making the machine adaptable to diverse cleaning requirements without requiring multiple separate devices.
