Wireless Keyboard Stylus Charging Coil Layout for Blind Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in quickly charging styluses due to the need for multiple alignments of wireless charging coils, which slows down the charging process.
Innovation Solution
A wireless keyboard with a circle-shaped charging coil in its accommodating portion and a corresponding circle-shaped charging coil in the stylus, allowing for 360° blind insertion charging, eliminating the need for coil alignment during charging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If traditional linear charging coils are used, then charging function is achieved, but multiple alignments are required which increases operation time and reduces charging speed
Solution Approach 1:
The patent applies circular coil structures instead of traditional linear coils. The first circular coil is disposed on the inner wall of the accommodating portion, and the second circular coil is disposed in the stylus. This circular configuration enables 360° blind insertion charging, eliminating the need for precise alignment operations and significantly reducing charging time.
2Productivity
If precise coil alignment is required, then charging efficiency can be maximized, but the device complexity increases due to alignment mechanisms
Solution Approach 1:
By using circular coils disposed at specific positions (first circular coil on the accommodating portion inner wall, second circular coil in the stylus), the patent achieves automatic alignment through the circular geometry itself. This maintains high charging efficiency while eliminating complex alignment mechanisms, as the circular shape naturally guides proper coil coupling during insertion.
3Ease of operation
If traditional charging coil configuration is used, then charging is possible, but user convenience deteriorates due to repeated alignment attempts
Solution Approach 1:
The circular coil configuration enables blind insertion charging where users simply insert the stylus into the accommodating portion without any alignment operations. The circular geometry ensures that the coils couple properly regardless of rotational orientation, eliminating repeated alignment attempts and improving user convenience.

Function Achieved in This Case
Enables rapid and convenient charging of the stylus by allowing it to be inserted without aligning the charging coils, improving portability and charging efficiency.
Implementation Method 1
a first charging coil is disposed on an inner wall of the accommodating portion, and a second charging coil corresponding to the first charging coil is disposed in the stylus

AI summary
Embodiments of this application provide an electronic device component. A first charging coil and a second charging coil are respectively disposed in a wireless keyboard and a stylus. At least one of the first charging coil and the second charging coil is a circle coil, and the circle coil is disposed around circumference of an accommodating portion or the stylus. The stylus can be charged when the stylus is blindly inserted into the accommodating portion, to resolve a prior-art problem that a user cannot quickly charge the stylus because the charging coils need to be aligned for a plurality of times when the stylus is charged.
