Magnetic Charging Cable and Stand for Portable Terminal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable terminal devices are difficult to use while charging, as charging stands often obstruct visual display and input operations, requiring users to interrupt work to charge the device.
Innovation Solution
A charging system comprising a charging stand and cable with magnetic attraction mechanisms that allow the device to be charged without being physically obstructed, enabling continued use during charging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the portable terminal device is placed on the charging stand to be charged, then the battery can be charged, but it becomes difficult to visually recognize the display and perform input operations
Solution Approach 1:
The charging system is divided into two independent charging methods: stand charging (for stationary charging) and cable charging (for mobile charging). This segmentation allows users to choose the appropriate charging method based on whether they need to use the device during charging, thereby resolving the contradiction between charging reliability and ease of operation.
Solution Approach 2:
The charging cable acts as an intermediary that enables charging while allowing the device to remain mobile and accessible. By introducing this intermediate charging solution, the system allows users to charge the device without placing it on the stand, thus maintaining display visibility and input operation capability.
2Reliability
If the portable terminal device is placed on the charging stand, then charging can occur, but the device must be removed from the stand to be used
Solution Approach 1:
The charging system is divided into two independent charging methods: stand charging (for stationary charging) and cable charging (for mobile charging). This segmentation allows users to choose the appropriate charging method based on whether they need to use the device during charging, thereby resolving the contradiction between charging reliability and ease of operation.
Solution Approach 2:
The device is preliminarily equipped with a charged terminal that can accept both stand charging and cable charging. This preliminary preparation allows users to switch between charging methods without interruption, preventing work interruptions and reducing time loss.
3Ease of operation
If the charging cable is mounted to the portable terminal device, then the device can be charged while mobile, but the terminal housing must be securely attached
Solution Approach 1:
The mechanical mounting connection between the terminal housing and the portable terminal device is replaced with a magnetic field-based attraction. The attracting portion in the terminal housing and the attracted portion in the device create a magnetic force that secures the connection, providing both ease of attachment and sufficient connection strength.
Solution Approach 2:
The mounting mechanism uses magnetic field strength as a controllable parameter. By adjusting the magnetic attraction force, the system achieves both easy attachment (low force required) and secure connection (sufficient holding force), resolving the contradiction between ease of operation and connection strength.
