Multi-Output Charging Housing With Protected Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional charging devices have limited output specifications, allowing only single-device charging at a time, leading to inefficiencies when multiple devices need to be charged simultaneously and are exposed to the environment, risking short circuits.
Innovation Solution
A charging device with multiple output terminals and a versatile design that includes a housing, circuit board, input, and output parts, allowing for various charging scenarios and methods, including wall-mounted configurations, to charge multiple devices simultaneously while protecting against environmental exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional charging devices provide single output specification, then device structure is simple, but charging efficiency is low when multiple devices need to be charged
Solution Approach 1:
The charging device is designed with multiple output terminals including USB Type-C interfaces and wireless charging coils, enabling it to charge different types of electronic devices simultaneously through various charging methods (wired and wireless), thus improving charging efficiency without requiring multiple separate charging devices
Solution Approach 2:
The charging device divides its output capabilities into separate independent terminals (first output terminal, second output terminal, third output terminal), each capable of operating independently to charge different devices simultaneously, allowing the system to handle multiple charging tasks in parallel
2Reliability
If terminals are exposed to air for connection, then ease of operation is improved, but reliability decreases due to short circuit risks
Solution Approach 1:
A protective cover structure is provided that can cover the exposed terminals when not in use, protecting them from environmental factors and potential short circuits, while allowing easy access when charging is needed
Solution Approach 2:
The protective cover is designed to prevent potential harmful effects (short circuits, dust, moisture) before they can occur by covering the terminals when the device is not being charged, thus proactively protecting against reliability issues
3Productivity
If multiple output terminals are provided for simultaneous charging, then charging efficiency is improved, but device complexity increases
Solution Approach 1:
The circuit board is designed with integrated charging circuits that can handle multiple charging protocols (wired charging, wireless charging) through a unified architecture, reducing the complexity that would otherwise result from having separate dedicated circuits for each charging method
Solution Approach 2:
Multiple charging functions (wired output, wireless output) are merged into a single integrated charging device with a common power input and control system, allowing simultaneous operation of multiple outputs while maintaining a relatively simple overall structure
