Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless power transmission is implemented using inductive pads or resonating coils, then wireless charging capability is provided, but electronic devices must be placed in a specific place for powering which compromises mobility and portability
Solution Approach 1:
The system divides the house into multiple zones, each with its own transmitter unit that can independently operate. This segmentation allows devices to be charged wirelessly in any zone without being confined to a single charging location, thereby maintaining mobility while providing wireless charging capability.
Solution Approach 2:
Each transmitter unit is designed to be universally applicable across different zones and can serve multiple functions: wireless power transmission, communication with receivers, and coordination with the base station. This multi-functionality enables devices to be charged wirelessly throughout the entire house, not just at fixed locations.
2Adaptability or versatility
If multiple transmitters are deployed across different locations for multiple room coverage, then wireless power availability is improved, but system complexity and cost increase
Solution Approach 1:
Multiple transmitter units are merged into a unified system through a central base station that coordinates their operation. The base station manages power distribution, communication protocols, and pocket-forming operations across all transmitters, reducing overall system complexity despite the distributed architecture.
Solution Approach 2:
Each transmitter unit operates autonomously to some extent, managing its own communication with receivers and coordinating with the base station only when necessary. This self-service capability reduces the control burden on the central base station and simplifies the overall system architecture.
3Reliability
If cables and conduit infrastructure are installed for power transmission, then reliable power delivery is achieved, but maintenance cost increases and aesthetic quality deteriorates
Solution Approach 1:
The patent replaces the mechanical cable and conduit infrastructure with a wireless electromagnetic field-based power transmission system. Transmitters generate RF signals that create power pockets in the air, eliminating the need for physical cable installation through walls and conduits, thereby reducing installation and maintenance costs while maintaining aesthetic quality.
4Adaptability or versatility
If wireless power transmission allows devices to remain portable during charging, then mobility is maintained, but power transmission reliability and efficiency decrease
Solution Approach 1:
The system continuously monitors the position, power consumption, and charging status of receivers through bidirectional communication. The base station uses this feedback to dynamically adjust pocket-forming parameters, signal power, and transmitter coordination, ensuring reliable power transmission even as devices move freely throughout the house.
