Mobile Device Wireless Earphone Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile devices with wireless earphones face issues of convenience in carrying and charging, as the earphones can be easily lost and require separate power sources, leading to inconvenience when power is low.
Innovation Solution
A mobile device design with a detachable wireless earphone that includes an accommodating recess for storage, where the earphone's electrical connectors switch on/off communication units based on attachment/detachment, allowing for convenient pairing and charging directly from the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the wireless earphone is kept separate from the mobile device, then the wireless earphone can work independently with its own power source, but the wireless earphone may be lost easily and the user may forget to carry it
Solution Approach 1:
The patent integrates the wireless earphone with the mobile device by providing an accommodating recess in the device body where the earphone can be stored. The earphone includes positioning structures that fit into corresponding structures in the recess, effectively combining the earphone with the device during non-use periods to prevent loss and ensure availability.
2Reliability
If the wireless earphone is kept separate from the mobile device, then the wireless earphone can work independently, but when the user needs to use the wireless earphone temporarily, the user has to take it out from a backpack or other containers which is inconvenient
Solution Approach 1:
The accommodating recess provides a dedicated storage location on the mobile device itself, eliminating the need to retrieve the earphone from separate containers. The earphone can be quickly accessed by simply removing it from the recess, significantly reducing retrieval time while maintaining independence when not in use.
3Reliability
If the wireless earphone works through an individual power source, then the wireless earphone can operate independently, but when the power of the wireless earphone is insufficient and cannot be charged in time, the user may be upset
Solution Approach 1:
The patent enables the mobile device to serve as a charging source for the wireless earphone through the accommodating recess structure. When the earphone is placed in the recess, electrical contacts allow power transfer from the device's power source to the earphone's battery, providing convenient charging without requiring separate charging equipment.
4Ease of operation
If the wireless earphone is integrated with the mobile device for charging and storage, then charging convenience is improved and loss is prevented, but the device structure becomes more complex
Solution Approach 1:
The patent divides the integration function into separate components: the accommodating recess in the device body for storage and charging, and the corresponding positioning structures on the earphone. This segmentation allows the complex functionality to be achieved through modular design, where each component has a specific role, reducing overall structural complexity while maintaining convenience.

AI summary
A mobile device includes a device body and a wireless earphone. A back of the device body has an accommodating recess. The device body includes a first processing unit, a first wireless communication unit and a first electrical connector. The first electrical connector is disposed in the accommodating recess. The wireless earphone includes a second processing unit, a second wireless communication unit and a second electrical connector. The wireless earphone is configured to be detachably accommodated in the accommodating recess of the device body. When the wireless earphone is detached from the accommodating recess, the first electrical connector and the second electrical connector are separated from each other, the first processing unit switches on the first wireless communication unit, and the second processing unit switches on the second wireless communication unit, such that the first wireless communication unit and the second wireless communication unit are paired with each other.
