Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wired charging stations are deployed in crowded areas, then power charging capability is provided, but the stations become crowded and spots are scarce making charging inconvenient
Solution Approach 1:
The patent segments the charging function from centralized stations to distributed mobile devices. Each mobile device becomes an independent charging unit that can provide power to others, effectively multiplying the number of available charging spots from a limited number of physical stations to potentially hundreds of user devices in the area.
Solution Approach 2:
Users with extra battery power automatically become charging providers for others in need. The system enables peer-to-peer power sharing where devices with sufficient charge can autonomously or on-request provide power to devices needing charge, eliminating the need to queue at centralized stations.
2Ease of operation
If mobile devices transmit controlled RF waves for power sharing, then wireless power transmission is enabled, but energy consumption increases
Solution Approach 1:
The system uses partial action by transmitting RF waves only when and where needed rather than continuously. Power is transmitted in targeted bursts to specific receivers that have established connections and demonstrated need, rather than maintaining constant transmission fields across the entire area, thus reducing overall energy consumption.
Solution Approach 2:
The patent implements local quality by creating focused pockets of RF energy at specific locations where receivers are positioned, rather than broadcasting energy uniformly across all space. The transmitters adjust their radiation patterns and power levels to concentrate energy only in the immediate vicinity of active receivers, minimizing wasteful energy dispersion.
