Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wireless power is transmitted in all directions to ensure coverage, then device charging reliability is improved, but electromagnetic interference increases
Solution Approach 1:
The patent applies local quality by transmitting electromagnetic energy directionally toward specific target devices rather than omnidirectionally. The system determines device locations and orientations, then directs power beams only where needed, reducing electromagnetic interference in non-target areas while maintaining charging reliability for identified devices.
2Object-generated harmful factors
If power beams are statically directed to fixed positions, then electromagnetic interference is reduced, but charging efficiency decreases when devices move
Solution Approach 1:
The patent implements dynamics by continuously tracking device locations and orientations, then dynamically adjusting the direction of power beams in real-time. This allows the system to maintain efficient charging for moving devices while keeping beams narrowly directed to minimize electromagnetic interference, resolving the contradiction between static beam stability and dynamic charging efficiency.
3Object-generated harmful factors
If directional power beams are used to reduce interference, then electromagnetic interference is minimized, but the system complexity increases
Solution Approach 1:
The patent employs feedback mechanisms where devices communicate their location and orientation information to the power transmission system. This feedback loop enables the system to automatically calculate and adjust beam directions without manual intervention, managing the complexity through automated control algorithms that respond to real-time device states.
4Adaptability or versatility
If the system continuously tracks and redirects power beams to moving devices, then charging adaptability is improved, but energy loss increases
Solution Approach 1:
The patent applies preliminary action by predicting or pre-determining device trajectories and orientations, then proactively adjusting power beam directions before devices move out of optimal charging positions. This reduces the need for frequent, energy-intensive beam redirections while maintaining charging adaptability, thereby reducing overall energy loss.
