Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current TWS earphones lack effective identification mechanisms, allowing unauthorized users to access and potentially eavesdrop on calls, compromising user privacy and experience.
Innovation Solution
An earphone wearing detection method that acquires ear data using 3D LiDAR, identifies the owner by matching collected data with pre-stored data, and controls the earphone to enter a normal or off state based on the user's proximity, ensuring only the owner can use it, while also analyzing age group and audio content suitability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If earphone connection is enabled without identification, then ease of operation is improved, but security and privacy protection deteriorate
Solution Approach 1:
The system performs preliminary identification of the user through ear detection before enabling earphone connection. The 3D LiDAR scans and recognizes the user's ear structure in advance, storing biometric data for future authentication, ensuring that only authorized users can connect and use the earphones.
Solution Approach 2:
The patent replaces traditional mechanical or manual identification methods with optical field-based 3D LiDAR technology. The LiDAR emits laser beams to scan the ear's three-dimensional structure, using light reflection and time-of-flight measurements to create precise spatial maps for biometric authentication.
2Reliability
If 3D LiDAR ear scanning is implemented, then security and privacy protection are improved, but device complexity increases
Solution Approach 1:
The 3D LiDAR module serves multiple functions: it scans the ear's three-dimensional structure for biometric identification, measures the distance between the ear and earphone for wearing detection, and provides spatial positioning information. This multi-functionality reduces the need for separate sensors and systems.
Solution Approach 2:
The patent combines the ear scanning, distance measurement, and identification functions into a single integrated 3D LiDAR system. The same optical sensor array and processing unit that capture ear geometry also measure proximity, eliminating the need for separate mechanical or optical sensors for each function.
3Reliability
If continuous distance monitoring is performed, then privacy protection is improved, but use of energy increases
Solution Approach 1:
Instead of continuous monitoring, the system performs distance detection at periodic intervals using the 3D LiDAR. The earphone periodically scans the ear's position and compares it with the stored biometric data, enabling privacy protection while reducing energy consumption compared to continuous real-time monitoring.

AI summary
The present disclosure discloses an earphone wearing detection method, device, apparatus, and computer-readable storage medium. The method comprising: acquiring ear data of a user collected during a wearing process of an earphone; identifying the user based on the ear data of the user and pre-stored ear data of an owner of the earphone, to judge whether the user is the owner: if the user is the owner, judging whether a distance between an ear thereof and the earphone is decreasing, if the distance is decreasing, controlling the earphone to enter a normal using state; or if the distance is not decreasing, controlling the earphone to enter an off state.
