Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If existing wireless charging technology is used, then charging convenience is improved, but power distribution efficiency deteriorates
Solution Approach 1:
The patent implements dynamic power distribution by continuously monitoring the usage states of multiple wearable devices and adjusting charging parameters in real-time. The charging device dynamically determines charging orders and power allocation based on current device states, transforming static charging into an adaptive, responsive system that optimizes power distribution efficiency while maintaining charging convenience.
Solution Approach 2:
The system establishes a feedback mechanism where the charging device receives usage state information from wearable devices, processes this data to determine optimal power distribution, and sends control instructions back to the devices. This closed-loop feedback enables continuous optimization of power allocation, resolving the contradiction between convenience and efficiency by making the system responsive to actual power needs.
2Duration of action of moving object
If battery capacity is increased to extend standby time, then usage duration is improved, but device weight increases
Solution Approach 1:
The patent merges multiple wearable devices into a single charging ecosystem where power is shared and coordinated. Instead of each device independently requiring large battery capacity for extended standby, the system combines the power resources and charging capabilities across multiple devices, allowing smaller batteries to achieve effective extended usage through coordinated power management and multiple charging sources.
Solution Approach 2:
The charging device serves multiple wearable devices simultaneously, providing universal power supply functionality. This multi-functional charging system allows each wearable device to have reduced battery capacity since the charging device can service multiple devices, effectively extending the operational duration of each device without increasing individual device weight.
3Speed
If wireless charging power is increased, then charging speed is improved, but power consumption control deteriorates
Solution Approach 1:
The patent implements precise control over charging parameters including power level, charging current, and magnetic field strength. The charging device adjusts these parameters dynamically based on the wearable device's usage state, battery level, and power requirements. This parameter optimization enables high charging speeds when needed while reducing power consumption during low-demand periods, resolving the contradiction between charging speed and power consumption control.
