Magnetic Clip Charger Alignment for Reliable Wearable Charging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic device-charger sets lack efficient and stable interlocking mechanisms for charging devices, particularly those with wearable designs, which can lead to positional misalignment and unreliable connections.
Innovation Solution
The electronic device-charger set incorporates a magnetically attracted clip system where a magnet on the device interacts with an opposing magnet on the charger, ensuring secure interlocking and stable charging by using shaped portions to guide the clip into a recessed area, facilitating easy and accurate alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a magnetic attraction system is implemented for interlocking the electronic device with the charger, then the reliability of connection is improved, but the device complexity increases due to additional magnetic components
Solution Approach 1:
The patent replaces traditional mechanical interlocking mechanisms with a magnetic field-based attraction system. Magnets are embedded in both the electronic device and the charger, creating a magnetic field that automatically attracts and secures the device to the charger during charging, eliminating the need for complex mechanical clips or latches
Solution Approach 2:
The patent utilizes magnetic field strength as a controllable parameter to achieve reliable connection. By adjusting the magnetic attraction force through carefully positioned magnets, the system ensures stable interlocking between the device and charger without requiring additional mechanical fastening components
2Manufacturing precision
If shaped portions are added to guide the clip into a recess, then the manufacturing precision of alignment is improved, but the device complexity increases due to additional structural components
Solution Approach 1:
The patent incorporates pre-formed shaped portions (protrusions and recesses) on the clip and charger body that guide the alignment process before the magnetic attraction takes full effect. These guiding features are created during the molding process, ensuring precise positioning without requiring additional assembly steps or complex adjustment mechanisms
Solution Approach 2:
The patent merges the alignment guidance function with the existing clip structure by integrating shaped portions directly into the clip and charger body designs. This combines multiple functions (mechanical support, alignment guidance, and magnetic mounting) into a unified structure, reducing the need for separate alignment components
