Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Long-distance wireless charging technologies face challenges in reducing radiation exposure to human safety, as higher power signals required for efficient charging can exceed safety regulations when a living body is present.
Innovation Solution
A wireless charging transmitter equipped with a detection component to identify the presence of a living body within a preset range, adjusting the transmitting power from a higher first power to a lower second power that complies with safety regulations, using a ranging component to determine the distance and adjust the power accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If high-power radiation signal is used for long-distance wireless charging, then charging efficiency is improved, but radiation impact on human safety worsens
Solution Approach 1:
The patent implements dynamic adjustment of transmitting power based on real-time detection of living bodies. The system transitions from static high-power transmission to dynamic power control, switching between first transmitting power (higher) and second transmitting power (lower) depending on whether a living body is detected within the preset range. This resolves the contradiction by making the system adaptive rather than fixed.
Solution Approach 2:
The patent introduces a detection component that provides feedback about the presence of living bodies to the power control mechanism. This feedback loop enables the system to automatically adjust transmitting power levels based on detected conditions, ensuring safety while maintaining charging efficiency when appropriate. The feedback mechanism directly addresses the safety concern while preserving productivity.
2Object-affected harmful factors
If transmitting power is reduced to comply with safety regulations, then radiation impact on human safety is reduced, but charging efficiency worsens
Solution Approach 1:
The system dynamically switches between two power levels based on detection results. When no living body is detected, the system operates at first transmitting power (higher efficiency). When a living body is detected, it switches to second transmitting power (lower radiation). This dynamic approach ensures safety compliance while maximizing charging efficiency when safe to do so.
Solution Approach 2:
The detection and power adjustment occurs periodically or continuously, allowing the system to alternate between high-power charging mode and low-power safety mode as conditions dictate. This periodic monitoring and adjustment ensures that safety requirements are met while maintaining optimal charging performance during safe operating periods.

AI summary
A wireless charging transmitter (100), a method for wireless charging and a storage medium. The method is applied to a transmitting component (110) for transmitting a wireless charging signal to a terminal to be charged to wirelessly charge the terminal. A detection component (120) is configured to detect whether there is a living body that has entered a preset range associated with the wireless charging transmitter (100), and generate a detection signal. An adjustment component (130) is connected to the transmitting component (110), and configured to adjust a first transmitting power of the transmitting component to a second transmitting power when the detection signal indicates that there is a living body that has entered the preset range, the second transmitting power is smaller than the first transmitting power..
