Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the conventional receiver stores electrical energy in an energy storage element before outputting to the energy consuming device, then the receiver can provide stable power supply, but the electrical energy loss increases and energy usage efficiency decreases
Solution Approach 1:
The patent segments the energy transfer process into two distinct modes: a first mode where energy flows directly from the RF generator module to the energy consuming device, and a second mode where energy flows through the energy storage element. The energy management module dynamically selects between these segments based on power conditions, thereby reducing unnecessary energy loss while maintaining stable power supply when needed.
Solution Approach 2:
The patent implements dynamic energy transfer by allowing the energy management module to switch between different energy transfer paths based on real-time power conditions. When the RF generator module's output power is sufficient, direct transfer is used; when insufficient, the energy storage element is engaged. This dynamic adaptation resolves the contradiction between energy efficiency and power stability.
2Stability of the object's composition
If the conventional receiver always performs electrical energy transfer twice through the energy storage element, then the receiver can maintain consistent operation, but the energy usage efficiency becomes low
Solution Approach 1:
The patent transforms the static, fixed energy transfer path into a dynamic system where the energy management module adjusts the transfer path based on real-time power conditions. This dynamic approach maintains operational consistency through intelligent control while improving energy usage efficiency by avoiding unnecessary double transfer when the RF generator module can directly satisfy the power demand.
Solution Approach 2:
The patent changes the operational parameters of the energy transfer system by introducing conditional logic based on power output levels. The energy management module monitors power parameters and adjusts the transfer configuration accordingly, switching between direct transfer and stored transfer modes to optimize energy usage efficiency while maintaining consistent operation.

AI summary
A wireless energy extracting device includes: a radio frequency (RF) generator module for wirelessly receiving an RF charging signal to generate electrical energy; a capacitor module; and an energy management module coupled to the RF generator module and the capacitor module, and used to be coupled further to an energy consuming device. The energy management module performs electrical energy transfer from at least the RF generator module to at least the energy consuming device. Therefore, the wireless energy extracting device has relatively low electrical energy loss and thus relatively high energy usage efficiency.
