Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electrical wiring is used to control components, then reliable power and control signal transmission is achieved, but device complexity increases and design flexibility is limited
Solution Approach 1:
The patent replaces the mechanical electrical wiring system with a wireless communication system. The controller wirelessly transmits control signals to the suction source, motor, and lights, eliminating the need for physical electrical connections between these components and the controller, thereby reducing device complexity while maintaining control reliability
Solution Approach 2:
The patent introduces a wireless communication intermediary (wireless transceiver system) between the controller and the controlled components. This intermediary enables control signal transmission without direct electrical wiring, resolving the contradiction between reliable transmission and reduced complexity
2Reliability
If electrical wiring is used to connect components, then stable power supply is ensured, but design flexibility and positioning freedom are reduced
Solution Approach 1:
The patent substitutes fixed electrical wiring with wireless power transmission technology. The controller can wirelessly supply power to components regardless of their physical position or orientation, enabling greater design flexibility while maintaining stable power delivery through wireless communication protocols
3Ease of operation
If wireless communication devices are integrated, then design flexibility and ease of operation are improved, but device complexity increases due to additional components
Solution Approach 1:
The patent merges the wireless communication functionality into the existing controller unit. The controller integrates both control signal generation and wireless transmission capabilities, eliminating the need for separate wireless communication modules and reducing overall device complexity while maintaining ease of operation
Solution Approach 2:
The controller is designed with multi-functionality, serving both as the control unit and the wireless communication device. This universal design allows the same component to perform multiple functions (control signal generation, wireless transmission, power management), reducing the total number of components and simplifying the system
