Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If higher power is received for charging, then charging speed is improved, but communication signal quality deteriorates due to increased noise
Solution Approach 1:
The patent implements dynamic adjustment of power reception levels based on real-time communication signal quality monitoring. The electronic device continuously monitors communication signal quality and adjusts the power reception level accordingly, transitioning between different power reception states (first, second, third levels) to maintain optimal performance. This dynamic control resolves the contradiction by making power reception adaptive rather than fixed, allowing the system to optimize both charging speed and communication quality in real-time
Solution Approach 2:
The patent employs a feedback mechanism where the electronic device monitors communication signal quality and uses this information to control power reception levels. The processor determines whether to maintain, increase, or decrease power reception based on feedback from signal quality measurements. This closed-loop feedback system enables the device to automatically balance charging efficiency and communication reliability, resolving the technical contradiction through continuous monitoring and adjustment
2Power
If power reception is increased to perform high-power charging, then charging efficiency is improved, but noise level increases affecting communication
Solution Approach 1:
The patent changes the power reception parameter dynamically based on communication signal conditions. The system defines multiple power reception levels (first, second, third levels) and transitions between them based on monitored signal quality. This parameter change approach allows the device to operate at high power when communication conditions permit, while reducing power (and thus noise) when communication quality degrades, effectively resolving the contradiction between power reception and noise generation
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables high-power charging while maintaining good communication signal quality by adjusting power reception in response to signal quality, reducing noise and improving overall performance.
Implementation Method 1
Power transmission by electromagnetic induction may be made by power transmission between a primary coil and a secondary coil. According to the phenomenon in which a moving magnet near the coils generates an induction current, the magnetic field may be generated at a transmitting end, and a current may be induced due to a change in the magnetic field at a receiving end
Implementation Method 2
The wireless charging system of an MIT team uses the physical concept of a resonance, such as when a wine glass near a vibrating tuning fork oscillates in the same frequency as the tuning fork. The team has used electromagnetic waves containing electrical energy instead of sounds.
