Solution Overview
Problem
Current battery technology often fails to meet the charge capacity and discharge rate demands of mobile electronic devices, limiting their range and requiring devices to be tethered to a fixed charging source, which restricts movement and causes 'cord clutter' as multiple devices charge simultaneously.
Innovation Solution
A wireless charging infrastructure that enables automated, price-negotiated wireless charging for devices, allowing them to charge automatically in various environments through a system of resonant wireless energy transfer, where devices can identify and negotiate with nearby transmitters for energy transfer based on real-time pricing and availability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wired charging is used to recharge devices, then charging reliability is improved, but device mobility and ease of operation deteriorate due to physical connections required
Solution Approach 1:
The patent replaces the mechanical wired charging system with a wireless electromagnetic field-based charging system. The transmitter generates an electromagnetic field that induces current in the receiver coil, eliminating the need for physical plug-and-play connections while maintaining charging functionality. This substitution directly resolves the contradiction by removing the mechanical constraint that limited device mobility.
Solution Approach 2:
The patent introduces an electromagnetic field as an intermediary medium between the power source and the device battery. Instead of direct electrical contact through wires, the electromagnetic field serves as the energy transfer medium, allowing charging to occur without physical connection. This intermediary approach maintains charging reliability while enabling device freedom of movement.
2Productivity
If multiple devices are connected to a charging source simultaneously, then charging productivity is improved, but cord clutter and system complexity increase
Solution Approach 1:
By replacing multiple physical charging cables with a single wireless electromagnetic field generation system, the patent eliminates cord clutter while maintaining the ability to charge multiple devices simultaneously. The transmitter can serve multiple receivers within its electromagnetic field range without requiring separate physical connections for each device.
Solution Approach 2:
The wireless charging transmitter is designed to serve multiple functions and multiple devices simultaneously within its operational range. A single transmitter can charge multiple receivers at once, making the system universal and eliminating the need for multiple separate charging sources or cables, thus reducing overall system complexity.
3Use of energy by moving object
If battery capacity is increased to meet power demands, then energy storage is improved, but device weight and volume increase
Solution Approach 1:
The wireless charging system performs preliminary action by continuously or periodically recharging the device battery while the device is in use, rather than waiting for the battery to deplete. This allows the battery to maintain a smaller capacity since it doesn't need to store enough energy for extended periods between charging sessions, thereby reducing device weight.
Solution Approach 2:
The patent enables continuous charging action through the wireless power transfer system, where energy is transferred continuously or periodically to the device battery during normal operation. This continuous energy replenishment allows for smaller battery capacity while maintaining adequate power supply, thus reducing device weight and volume.
