Solution Overview
Problem
Existing wireless charging devices are unreliable as they fail to securely hold portable electronic devices during charging, leading to a risk of the devices falling and being damaged.
Innovation Solution
A wireless charging device with a charging panel featuring through holes and slippery mats for stability, along with absorbent units equipped with vacuum suction cups to securely position and absorb the device, preventing it from falling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a portable electronic device is arranged on a charging panel of a wireless charging device, then wireless charging can be performed, but the device is easy to fall from the charging panel and may be damaged
Solution Approach 1:
The patent applies pneumatic suction cups to create a vacuum-based holding mechanism. The suction cups generate negative pressure to吸附 (adsorb/hold) the portable electronic device on the charging panel, preventing it from falling during wireless charging. This pneumatic approach directly addresses the reliability issue by providing secure mechanical retention without adding complex mechanical structures.
2Reliability
If absorbent units with vacuum suction cups are added to secure the device, then the device can be held firmly, but the device complexity increases
Solution Approach 1:
The charging panel is designed with multi-functionality: it serves both as the wireless charging surface and as the mounting structure for the suction cups. The panel integrates multiple suction cups that can simultaneously hold different types of portable devices. This universal design approach increases reliability without proportionally increasing complexity, as the same panel structure supports both charging and securing functions.
