Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a shared wireless charging apparatus is used to charge multiple electronic devices, then device versatility and user convenience are improved, but charging management complexity and power distribution efficiency deteriorate
Solution Approach 1:
The patent introduces an authentication server as an intermediary between the wireless charging apparatus and multiple electronic devices. The server manages authentication requests, device identification, and charging authorization, thereby offloading the management complexity from the charging apparatus itself while enabling support for multiple devices.
Solution Approach 2:
The charging system is segmented into distinct functional modules: the wireless charging apparatus handles power transmission, the authentication server manages device verification and charging rights, and individual electronic devices provide their own power information. This segmentation distributes the management complexity across separate components.
2Productivity
If charging priorities are assigned based on power information for multiple devices, then charging efficiency is improved, but system complexity and authentication overhead increase
Solution Approach 1:
The patent uses power information parameters (such as remaining battery level, power consumption rate, and charging urgency) as changeable variables to dynamically determine charging priorities. The authentication server compares these parameters across multiple devices and adjusts charging allocation accordingly, enabling efficient power distribution without requiring complex hard-coded priority rules.
3Reliability
If authentication is required for wireless charging service, then charging stability and power management are improved, but charging speed and user convenience deteriorate
Solution Approach 1:
The authentication server performs preliminary verification of device identities and charging eligibility before power transmission begins. By pre-establishing authentication status and charging rights, the system avoids repeated authentication delays during the charging process, thereby maintaining stability while reducing time loss.
4Ease of operation
If power is wirelessly transmitted to authenticated devices, then user convenience and device portability are improved, but power transmission efficiency and energy loss increase
Solution Approach 1:
The system implements feedback mechanisms where electronic devices transmit their power reception status and efficiency information back to the authentication server. The server uses this feedback to monitor and adjust power allocation, identifying and stopping power transmission to devices with poor coupling or excessive energy loss, thereby reducing overall energy waste while maintaining wireless convenience.
