Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If a slip ring is used to enable endless panning, then the camera can perform continuous rotation operations, but the structure becomes complex and the number of operation times is limited due to mechanical contact wear
Solution Approach 1:
The patent replaces the mechanical contact-based slip ring system with a wireless power transmission system using electromagnetic fields. The power transmitter and power receiver enable contactless power and signal transmission, eliminating mechanical wear and structural complexity while allowing endless rotation operations.
2Reliability
If a slip ring with multiple rotating terminals is used, then power and signals can be transmitted during rotation, but the manufacturing cost increases due to high precision requirements
Solution Approach 1:
The patent substitutes the complex mechanical slip ring assembly with wireless electromagnetic power transmission components. This eliminates the need for high-precision mechanical manufacturing of multiple rotating terminals while maintaining reliable power and signal transmission through electromagnetic coupling between the power transmitter and power receiver.
3Duration of action of stationary object
If mechanical contacts are used for power and signal transmission, then continuous power supply is achieved, but the reliability decreases due to contact wear and limitation on operation times
Solution Approach 1:
The patent replaces mechanical contact-based power transmission with wireless electromagnetic power transmission. The power transmitter and power receiver enable continuous power supply without mechanical wear, eliminating the reliability limitations inherent in contact-based systems while maintaining endless rotation capability.
