Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional wireless power transmitting apparatus transmits power to multiple devices simultaneously, then the number of devices served increases, but the total power exceeds the maximum power capacity of the apparatus
Solution Approach 1:
The patent implements dynamic power adjustment by continuously monitoring the power requirements of multiple wireless devices and adjusting the transmission power in real-time. The control unit dynamically allocates power among devices based on their current needs, ensuring the total power remains within the maximum capacity while serving multiple devices simultaneously. This resolves the contradiction by making the power transmission system adaptable rather than fixed.
Solution Approach 2:
The system changes the power transmission parameter (power level) based on the number and requirements of connected devices. When multiple devices are detected, the apparatus adjusts the power transmission parameters to distribute available power efficiently, preventing total power from exceeding maximum capacity while still enabling service to multiple devices. This parameter adaptation resolves the contradiction between serving more devices and maintaining power within limits.
2Loss of energy
If wireless power transmitting apparatus adjusts operating power to fit multiple devices, then power utilization efficiency improves, but control complexity increases
Solution Approach 1:
The patent employs feedback mechanisms where the control unit continuously monitors power consumption of each wireless device and adjusts transmission power accordingly. This feedback loop enables efficient power utilization by matching supply with actual demand, reducing energy waste. The automated feedback-based control manages the complexity by using systematic monitoring and adjustment rather than manual intervention.
Solution Approach 2:
The wireless power transmitting apparatus performs self-adjustment of power levels based on automatic detection of device requirements. The system independently monitors power consumption patterns and adjusts transmission parameters without external intervention, improving power utilization efficiency while managing control complexity through autonomous operation.
3Adaptability or versatility
If wireless power transmitting apparatus serves multiple devices with different power requirements, then versatility improves, but difficulty in power allocation increases
Solution Approach 1:
The patent implements preliminary detection of device power requirements before full power transmission begins. The control unit预先 identifies the power needs of each wireless device type and prepares appropriate power allocation strategies in advance. This preliminary action simplifies the subsequent power allocation process by having pre-established parameters for different device types, reducing the difficulty of real-time power distribution while maintaining versatility.
Solution Approach 2:
The system segments power allocation into discrete levels or zones based on device types and power requirements. By dividing the power distribution into manageable segments rather than continuous adjustment, the apparatus handles diverse device requirements more easily. Each segment corresponds to specific power levels suitable for different device categories, simplifying the allocation process while maintaining adaptability to various device types.
