Charging Station Electrode Layout for Sequential Safe Recharging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic devices with charging stations pose safety concerns due to the risk of spark generation and electric shock from the simultaneous contact of positive and negative conducting strips, and the need for precise alignment during recharging.
Innovation Solution
The electronic device features a charging station with electrodes on different planes, allowing the main unit to connect first with one electrode and then the other, preventing simultaneous contact and reducing the risk of electric shocks, while also enhancing safety by positioning the electrodes on distinct surfaces to avoid accidental touch.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the positive and negative conducting strips are arranged on the same plane for recharging, then the recharging connection can be established, but spark generation and short circuit risks occur due to simultaneous contact of both electrodes
Solution Approach 1:
The patent transitions from a two-dimensional same-plane arrangement to a three-dimensional configuration where positive and negative electrodes are positioned on different planes or surfaces. This spatial separation in multiple dimensions prevents simultaneous contact during connection, eliminating spark generation while maintaining effective recharging connection.
2Ease of operation
If the positive and negative conducting strips are arranged on the same plane, then electrical connection can be established, but user safety is compromised due to risk of accidental electric shock from simultaneous contact
Solution Approach 1:
By positioning electrodes on different planes or surfaces, the patent creates a three-dimensional safety barrier that prevents user fingers from simultaneously contacting both positive and negative terminals. This spatial separation maintains ease of connection while eliminating the electric shock hazard associated with same-plane arrangements.
3Reliability
If precise alignment is required for recharging connection, then reliable electrical contact is achieved, but positioning difficulty and operational complexity increase
Solution Approach 1:
The patent divides the connection interface into distinct spatial zones with positive and negative electrodes separated on different planes. This segmentation allows for independent, simplified alignment of each electrode contact point rather than requiring precise simultaneous alignment of multiple contacts, reducing positioning difficulty while maintaining connection reliability.

AI summary
An electronic device includes a charging station and a main unit. The charging station has a first electrode and a second electrode. The first electrode and the second electrode form an angle therebetween, and the main unit has a third electrode and a fourth electrode. When the main unit is connected to the charging station, the main unit firstly contacts the second electrode with the fourth electrode, and then contacts the first electrode with the third electrode, so as to be recharged by the charging station.
