Wireless Headset Detachable Interface Charging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless headsets face challenges in charging, especially in situations where a power source is not readily available, such as during travel, due to the need for a separate charging cable and the inability to easily connect to a power supply.
Innovation Solution
A wireless headset design featuring a detachable interface that allows charging through a connected electronic device, such as a smartphone, using a USB-C connector, which eliminates the need for an additional charging cable and enables charging in various scenarios.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a separate charging cable is used to charge the wireless headset, then the battery can be charged, but the user must carry additional charging equipment and cannot charge conveniently when traveling
Solution Approach 1:
The patent merges the charging function with the audio transmission function by integrating a charging interface into the headset structure. The same interface that connects to the electronic device for audio output also serves as the charging port, eliminating the need for separate charging cables and equipment.
Solution Approach 2:
The headset interface is designed to perform multiple functions: it serves as both the audio transmission connection and the charging port. This multi-functional design allows the user to charge the headset simply by connecting it to any electronic device, without requiring dedicated charging equipment.
2Reliability
If the wireless headset uses a dedicated charging port, then charging is reliable, but the headset cannot be charged in situations where power outlets are unavailable
Solution Approach 1:
By making the audio connection interface also serve as the charging port, the headset can be charged from any electronic device with a compatible interface, greatly expanding the charging scenarios from fixed power outlets to any portable electronic device.
Solution Approach 2:
The electronic device that the user already carries and uses for audio playback also serves as the power source for charging. The user leverages existing resources (the electronic device) to fulfill the charging need, eliminating dependency on external power infrastructure.
3Use of energy by moving object
If the headset interface is always connected to the electronic device, then charging can occur, but audio transmission cannot function properly
Solution Approach 1:
The system dynamically switches between charging mode and audio transmission mode based on the connection state. When the interface is connected to an electronic device, the system can operate in either mode depending on the operational context, allowing flexible transition between charging and audio playback functions.

AI summary
A wireless headset includes a first headset part and a second headset part. The first headset part includes a first earplug, a battery box, and a first part of a cable control box. The first part of the cable control box includes a first interface, a first wireless chip configured to receive and send a wireless signal, and a processor configured to process the wireless signal. The battery box includes a first battery. The second headset part includes a second earplug and a second part of the cable control box, and the second part of the cable control box includes a second interface. The first interface is detachably connected to the second interface. When the first interface is electrically connected to the second interface, a data path is formed between the second earplug and the processor, and the first battery supplies power to the second earplug.
