Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If wireless power transmitters use fixed transmission paths, then system complexity is reduced, but energy transfer efficiency deteriorates when receivers move along networks of interlinked prescribed paths
Solution Approach 1:
The patent implements dynamic beam steering capability in wireless power transmitters, allowing the transmission paths to be adjusted in real-time based on the receiver's position within the network of interlinked prescribed paths. This dynamic adaptation enables efficient energy transfer across multiple interconnected paths without requiring fixed transmitter-receiver alignments, thereby resolving the contradiction between maintaining simple system architecture and achieving high energy transfer efficiency in complex path networks.
Solution Approach 2:
The system incorporates position tracking of wireless power receivers and uses this feedback information to dynamically control the steering of transmission beams. The feedback loop continuously monitors receiver location and adjusts transmitter beam directions accordingly, enabling the system to maintain optimal energy transfer efficiency as receivers move through the network of interlinked paths while managing system complexity through automated control.
2Productivity
If wireless power transmitters dynamically adjust energy transmission based on receiver position, then energy transfer efficiency improves, but device complexity increases
Solution Approach 1:
The patent pre-establishes a network of interlinked prescribed paths with known geometric configurations and pre-configures the wireless power transmitters with the capability to serve multiple paths. By preparing the system in advance with predetermined path information and multi-path transmission capabilities, the system can efficiently handle dynamic receiver positions without requiring complex real-time calculations, thus improving energy transfer efficiency while managing transmitter control complexity.
Solution Approach 2:
The wireless power transmitters are designed with multi-functionality to serve multiple interlinked prescribed paths simultaneously or sequentially. Each transmitter is equipped with steerable beams that can be directed along different paths, allowing a single transmitter to handle various receiver positions and path configurations. This universal design improves energy transfer efficiency across the network while avoiding the need for dedicated transmitters for each path, thereby controlling overall system complexity.
3Reliability
If steerable beams are used to track receiver position, then uninterrupted power supply is achieved, but loss of energy increases due to beam steering requirements
Solution Approach 1:
The patent implements continuous beam steering along prescribed paths to maintain uninterrupted power transfer to moving receivers. By continuously adjusting the beam direction to track the receiver's position along the network of interlinked paths, the system ensures continuous energy delivery without interruptions. This continuous useful action maintains reliability of power supply while minimizing energy loss by avoiding complete beam reconfiguration and maintaining optimal transmission conditions throughout the receiver's movement.
