Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless peripheral devices, such as computer mice, often require cumbersome charging cables due to poor battery life, which defeats the purpose of wireless technology, especially for devices that require constant use and movement.
Innovation Solution
A removable modular insert with magnetic and electrical coupling is used within a host device, allowing for wireless charging via a conductive coil when the device is placed on a powered base, such as a computer mouse pad, enabling continuous operation without auxiliary power sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If a charging cable is used to extend battery life, then the device can operate longer, but the device loses portability and convenience
Solution Approach 1:
The patent replaces the mechanical connection of a charging cable with an electromagnetic field-based wireless power transfer system. The base device generates an electromagnetic field that inductively couples with a coil in the portable device, eliminating the need for physical cable connection while enabling power transfer for extended operation.
2Ease of operation
If a wireless charging base is used to charge the device, then the device can be recharged without cables, but the device must remain immobile on the base
Solution Approach 1:
The patent implements a system where the base device continuously generates an electromagnetic field while the portable device moves across its surface. The portable device's coil continuously inductively couples with this field, enabling ongoing power transfer and charging throughout the device's operational period, not just when stationary on the base.
3Adaptability or versatility
If the portable device moves away from the base device, then the device gains mobility, but the electromagnetic coupling and power transfer are lost
Solution Approach 1:
The patent creates a dynamic power transfer system where the base device continuously emits electromagnetic energy across its entire surface area. As the portable device moves across the base, it maintains inductive coupling with the electromagnetic field at different locations, allowing continuous power transfer throughout the movement range rather than requiring a fixed position.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables continuous operation of wireless peripheral devices like computer mice by maintaining electromagnetic power emission even when communication is lost temporarily, ensuring uninterrupted charging during use and movement.
Implementation Method 1
A conductive coil can be coupled to the modular insert to electromagnetically receive power from a base device having a surface
Implementation Method 2
The apparatus can include one or more conductive contacts disposed on the removable modular insert to magnetically couple to the one or more magnets and secure the modular insert within the housing of the host device

AI summary
An apparatus including a removable modular insert disposed within a housing of a host device, the housing including one or more magnets, and one or more conductive contacts disposed on the removable modular insert to magnetically couple to the one or more magnets and secure the modular insert within the housing of the host device, and electrically couple the modular insert to the host device. A conductive coil can be coupled to the modular insert to electromagnetically receive power from a base device having a surface, where the host device moves and operates along the surface of the base device. The apparatus can include a communication device and a processor to control the communication device for communication between the modular insert and the host device, and control operation of the conductive coil. The communication device further controls the electromagnetic coupling between the modular insert and the base device.
