Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wired power supply is used, then reliable energy transmission is achieved, but mobility and location independence are restricted
Solution Approach 1:
The patent replaces the mechanical wired connection system with a wireless electromagnetic energy transmission system. The mechanical plug-and-socket connection is substituted by electromagnetic fields that can transmit energy through air space, eliminating the need for physical contact and enabling mobile devices to receive power without being tethered to power outlets.
Solution Approach 2:
The patent introduces electromagnetic fields as an intermediary medium to transfer energy between the power source and the device. Instead of direct electrical contact through cables, the electromagnetic field acts as a mediator that carries energy across the air interface, enabling wireless power transfer while maintaining reliable energy transmission.
2Ease of operation
If battery power is used, then mobility is improved, but continuous operation is limited by battery capacity and replacement needs
Solution Approach 1:
The patent enables continuous operation by providing uninterrupted wireless power supply. Instead of relying on finite battery capacity that requires periodic replacement or recharging, the system continuously transmits electromagnetic energy to the device, allowing it to operate indefinitely as long as it remains within the power transmission range and the power source is active.
3Ease of operation
If wireless charging systems are used, then mobility during charging is improved, but precise positioning requirements reduce flexibility
Solution Approach 1:
The patent employs dynamic tracking and adjustment mechanisms that allow the system to adapt to changing positions of mobile devices. The wireless power transmission system dynamically adjusts beam direction, focus, and intensity to maintain effective power transfer even as devices move, eliminating the need for fixed positioning while ensuring reliable charging.
