Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless charging is implemented without environment change detection standards, then wireless charging convenience is improved, but safety and reliability deteriorate due to potential over-powering from rogue objects or moisture exposure
Solution Approach 1:
The patent implements a feedback mechanism where the wireless power receiving unit detects environment changes (such as wired charging connection status) and notifies the wireless power transmitting unit. The transmitting unit then adjusts or stops power transmission based on this feedback, preventing over-powering while maintaining wireless charging convenience.
Solution Approach 2:
The patent applies preliminary action by detecting environment changes before harmful effects occur. The receiving unit continuously monitors for conditions like wired charging connections and notifies the transmitting unit in advance, allowing the system to prevent over-powering before it damages the device.
2Device complexity
If wireless charging system lacks environment change notification capability, then system simplicity is maintained, but charging efficiency deteriorates due to inability to adapt to environment changes
Solution Approach 1:
The patent introduces a feedback channel where the receiving unit notifies the transmitting unit of environment changes. This allows the system to adapt charging parameters to current conditions, improving charging efficiency without significantly increasing system complexity through standardized notification protocols.
Solution Approach 2:
The patent implements dynamics by enabling the charging system to adapt to changing environments. The transmitting unit dynamically adjusts power transmission based on real-time environment change notifications from the receiving unit, optimizing charging efficiency under varying conditions.
3Duration of action of moving object
If wireless charging continues without detecting wired charging connection, then continuous power transmission is maintained, but harmful effects occur due to over-powering
Solution Approach 1:
The patent applies preliminary anti-action by detecting wired charging connections before over-powering damage can occur. When the receiving unit detects a wired charging connection, it notifies the transmitting unit to stop or reduce power transmission, preventing harmful over-powering effects.
Solution Approach 2:
The patent uses feedback to prevent over-powering by continuously monitoring environment changes and communicating them from the receiving unit to the transmitting unit. This feedback loop enables the system to stop power transmission when wired charging is detected, eliminating the harmful effect of simultaneous dual charging.
