Tablet Keyboard Stylus Charging Cradle for Secure Wireless Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless charging solutions for electronic styluses in tablet computers result in poor portability due to the stylus falling off and the need for separate handling, compromising the integrity and aesthetics of the system.
Innovation Solution
A wireless charging system integrating a tablet computer, wireless keyboard, and electronic stylus with multiple wireless charging coils and control modules, allowing for both forward and reverse wireless charging, and a receiving cavity for stylus storage, enhancing portability and convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wireless charging coils are arranged in both tablet computer and electronic stylus for wireless charging, then wireless charging function is achieved, but the electronic stylus tends to fall off from the tablet computer due to weak attraction
Solution Approach 1:
The patent combines the wireless charging function with the stylus receiving function by integrating wireless charging coils into the keyboard body that can simultaneously charge and retain the stylus. The keyboard body includes a receiving cavity with wireless charging coils that provide both magnetic attraction for retention and wireless power transfer, merging two functions into one integrated system.
2Reliability
If electronic stylus is separately received and charged from tablet computer and wireless keyboard, then charging function is achieved, but portability of the entire system deteriorates
Solution Approach 1:
The keyboard body is designed with multi-functionality: it serves as both an input device and a charging station for the stylus. The receiving cavity in the keyboard body can receive and wirelessly charge the stylus, eliminating the need for separate charging devices and improving system portability by consolidating functions.
3Adaptability or versatility
If receiving cavity is arranged in wireless keyboard for stylus storage, then integration of receiving and wireless charging is achieved, but device complexity increases
Solution Approach 1:
The patent merges the receiving cavity structure with the wireless charging coil assembly in the keyboard body. The same cavity that receives the stylus also houses the wireless charging coils, combining structural support and charging functionality into a single integrated component rather than adding separate systems.
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
The system enables simultaneous wireless charging of the wireless keyboard and electronic stylus, improving portability and integration by allowing the stylus to be received and charged within the keyboard, ensuring stable voltage and current management.
Implementation Method 1
the first wireless output coil is connected to the first wireless output control module... the first wireless receiving coil receives an electromagnetic signal sent by the first wireless output coil
