Innovation Solution
A wireless charging system that integrates a tablet computer, a wireless keyboard, and an electronic stylus, where the wireless keyboard includes a support for the tablet computer and a connection portion to adjustably connect the keyboard body and the support, allowing for wireless charging of the stylus while it is accommodated.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wireless charging is implemented with tablet computer and electronic stylus each being provided with a wireless charging coil, then wireless charging function is achieved, but the electronic stylus is apt to fall off due to weak adhesion
Solution Approach 1:
The patent combines the accommodation function and wireless charging function into a single integrated structure. The wireless keyboard's connection portion serves dual purposes: it accommodates the electronic stylus and provides wireless charging through an integrated wireless charging coil, eliminating the need for separate adhesion mechanisms while ensuring reliable stylus retention during charging.
Solution Approach 2:
The connection portion of the wireless keyboard is designed with multi-functionality, serving as both an accommodation cavity for the electronic stylus and a wireless charging device. This universal design allows the same structure to perform multiple functions (storage and charging), reducing overall system complexity while maintaining reliable stylus retention.
2Adaptability or versatility
If wireless keyboard and electronic stylus are accommodated as accessories, then functionality is enhanced, but portability deteriorates due to additional accommodation requirements
Solution Approach 1:
The wireless keyboard is designed with multi-functionality, integrating the stylus accommodation and wireless charging capabilities into its existing structure. The connection portion serves as both a structural element and an accommodation cavity, eliminating the need for separate stylus storage compartments and maintaining portability while enhancing accessory functionality.
Solution Approach 2:
The patent merges the stylus accommodation function with the wireless charging function in a single integrated component (the connection portion). This combination reduces the overall number of separate components and their associated weights, improving portability while maintaining full accessory functionality.
3Reliability
If multiple chips are disposed in charging link, then charging control is improved, but costs increase
Solution Approach 1:
The patent combines multiple charging control functions into a single integrated wireless charging coil in the connection portion. This unified design consolidates what would traditionally require multiple separate chips and components, reducing manufacturing complexity and cost while maintaining reliable charging control through the integrated structure.
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

AI summary
This application discloses a wireless charging system, and relates to the field of terminal technologies. The wireless charging system has a function of wirelessly charging an electronic stylus while accommodating the electronic stylus, so that integration of accommodation and wireless charging is implemented. In addition, a length of a wireless charging link is reduced, and a quantity of chips used in the link is reduced, thereby improving charging efficiency and reliability and reducing costs. The wireless charging system includes a tablet computer, a wireless keyboard, and the electronic stylus. The wireless keyboard includes a keyboard body, a support, and a connection portion. The connection portion includes an accommodation cavity provided with an opening at one end. A first sending apparatus is disposed in the tablet computer. A first receiving apparatus is disposed in the keyboard body. A second sending apparatus is disposed in the accommodation cavity. The first receiving apparatus receives an alternating current signal sent by the first sending apparatus, and then directly transmits the alternating current signal to the second sending apparatus. The second sending apparatus is configured to wirelessly charge the electronic stylus accommodated in the accommodation cavity.
