Innovation Solution
A charger with a moveable platform and electronic processor that positions devices within a charging coil for efficient wireless charging, determines charge levels, and moves devices out when they reach a predetermined threshold to charge other devices in a sequence, ensuring all devices are charged efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a wireless charging system charges multiple devices simultaneously, then charging efficiency is improved, but device complexity and status monitoring difficulty increase
Solution Approach 1:
The system divides multiple devices into separate charging zones (first charging zone with first charging coil, second charging zone with second charging coil) that can operate independently. Each zone has its own charging coil and control logic, allowing the system to manage multiple devices without overwhelming complexity by treating them as separate manageable units rather than a single complex charging process
2Productivity
If a wireless charging system charges multiple devices simultaneously, then charging throughput is improved, but monitoring charge status becomes difficult
Solution Approach 1:
The system incorporates detection circuits in each charging zone that continuously monitor the charge status of devices. The electronic controller receives feedback signals from these detection circuits about the charge levels of devices in both charging zones, enabling automatic control of the charging process including switching between zones based on real-time charge status without requiring manual monitoring
Solution Approach 2:
The system automatically manages the charging process without user intervention. The electronic controller autonomously determines when to switch between charging zones based on detected charge levels, and automatically positions devices using the moveable platform. Users simply place devices on the charging surface and the system handles all monitoring and control independently
3Volume of moving object
If a compact charger design is used, then portability is improved, but space for multiple devices is limited
Solution Approach 1:
The system employs a moveable platform that can dynamically reposition devices between charging zones. This dynamic positioning capability allows a single compact charging coil to serve multiple devices sequentially by moving them into position, effectively increasing the number of devices that can be charged without requiring proportionally more charging coils or increasing the overall charger size
Solution Approach 2:
Each charging zone is designed to be universal and can charge different types of devices that support wireless charging. The moveable platform serves multiple functions: positioning devices for charging, transitioning between charging zones, and managing device placement. This multi-functionality allows the compact charger to handle multiple devices of various types without requiring dedicated charging areas for each device type
