Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wireless communication and power supply are implemented without physical wiring, then freedom of arrangement and reliability are improved, but system complexity increases
Solution Approach 1:
The patent combines wireless communication functionality and wireless power supply functionality into an integrated system. The base wireless device simultaneously handles both data communication and power transmission to remote wireless devices and sensor devices, eliminating the need for separate wired connections and reducing overall system complexity despite adding wireless capabilities.
Solution Approach 2:
The base wireless device is designed with multi-functionality, serving as both a communication hub and a power supply unit. It can communicate with multiple types of devices (remote wireless devices and sensor devices) and perform both data transmission and wireless power supply, reducing the need for specialized components and simplifying system architecture.
2Reliability
If wireless power supply is used instead of wired power supply, then reliability is improved by eliminating wiring disconnection risks, but energy loss increases
Solution Approach 1:
The patent replaces the mechanical wired power supply system with a wireless electromagnetic field-based power transmission system. This substitution eliminates physical contact points that are prone to disconnection and wear, significantly improving reliability. The system uses electromagnetic induction or radiation to transfer power without physical connectors.
3Adaptability or versatility
If multiple wireless devices are deployed without centralized control, then adaptability is improved, but system coordination becomes difficult
Solution Approach 1:
The patent segments the wireless system into a centralized base wireless device and multiple remote wireless devices/sensor devices. The base device acts as a coordinator managing power allocation and communication, while remote devices focus on specific functions. This segmentation allows flexible deployment of multiple devices while maintaining centralized control for coordination.
Solution Approach 2:
The system implements feedback mechanisms where remote wireless devices and sensor devices report their status, power needs, and environmental data back to the base wireless device. The base device uses this feedback information to dynamically adjust power distribution and communication strategies, enabling coordinated operation of multiple devices without complex manual configuration.
