Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If electromagnetic signal power is boosted to increase received power over distance, then received signal power is improved, but energy wastage increases and hazardous effects occur
Solution Approach 1:
The patent applies local quality by creating concentrated energy pockets at specific spatial locations where receivers are positioned, rather than broadcasting energy uniformly in all directions. The transmitter forms localized high-energy regions through constructive interference of RF waves, ensuring that energy is delivered precisely where needed while minimizing energy wastage in surrounding areas.
Solution Approach 2:
The patent transitions from traditional two-dimensional planar energy distribution to three-dimensional energy pocket formation. By manipulating RF waves in three-dimensional space and creating volumetric energy pockets, the system achieves more efficient energy delivery and reduces overall energy consumption while maintaining effective power transmission over distance.
2Productivity
If directional power transmission is used to enhance transmission efficiency, then power transmission efficiency is improved, but device location tracking and alignment complexity increase
Solution Approach 1:
The patent implements self-service by enabling receivers to autonomously communicate their locations to the transmitter using Bluetooth or similar communication protocols. The transmitter automatically tracks receiver positions and dynamically adjusts energy pocket formation without requiring manual alignment or complex user intervention, thereby maintaining high transmission efficiency while simplifying operation.
Solution Approach 2:
The system employs feedback mechanisms where receivers continuously report their positions to the transmitter via communication protocols. The transmitter uses this feedback information to dynamically adjust and reform energy pockets in real-time, ensuring optimal power transmission efficiency while automatically adapting to device movement and position changes.
3Adaptability or versatility
If a predetermined number of communication channels are used to communicate with multiple wireless power receivers, then communication capability is improved, but channel allocation complexity and interference management increase
Solution Approach 1:
The patent applies universality by using a predetermined set of communication channels for multiple purposes: initial receiver identification, location reporting, power transmission coordination, and acknowledgment signaling. This multi-functional use of limited channels simplifies the communication architecture while maintaining the ability to serve multiple receivers simultaneously, reducing overall system complexity.
Solution Approach 2:
The system employs periodic action through time-division multiplexing of communication channels, where channels are allocated to different receivers in alternating time slots. This periodic channel allocation allows the transmitter to communicate with multiple receivers using a predetermined number of channels without causing interference, as each receiver receives dedicated time windows for communication.
