Bone Conduction Earbud with Adhesive Tape Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current headsets and earphone devices are uncomfortable for users when lying down, often causing pain and dislodging due to their size and bulkiness, which limits their use for wireless audio transmission.
Innovation Solution
A wireless earbud device system using bone conduction technology, where a top cover housing a printed circuit board and battery is secured to a male bottom cover with tape attached to a female bottom cover, allowing secure attachment to the skin outside the ear for comfortable listening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional in-ear headsets are used, then wireless audio transmission is achieved, but user comfort deteriorates when lying down due to pressure on the ear
Solution Approach 1:
The patent moves the audio transmission device from inside the ear canal to the outer surface of the ear, utilizing the skin surface as a new dimension for device placement. This dimensional shift allows the device to transmit audio vibrations through the skull bone without pressing into the ear canal, thereby eliminating ear pain while maintaining wireless audio functionality.
Solution Approach 2:
The patent replaces the traditional mechanical in-ear insertion method with bone conduction technology. Instead of mechanically inserting the device into the ear canal, the device uses vibrational energy transmission through the skull bone to deliver audio signals, substituting a mechanical insertion system with a vibration-based transmission system.
2Reliability
If traditional in-ear headsets are used, then audio transmission is achieved, but device stability deteriorates as headsets fall out during activities
Solution Approach 1:
The patent divides the headset system into two separate components: a reusable audio transmission unit and a disposable adhesive tape component. The adhesive tape is applied to the skin first, and the audio unit is then attached to the tape. This segmentation allows the adhesive component to be optimized for skin attachment while the audio unit remains separate and replaceable.
Solution Approach 2:
The patent applies adhesive tape to the skin surface before attaching the audio transmission device. This preliminary action of securing the tape to the skin creates a stable base that prevents the device from falling out during physical activities, ensuring device retention without requiring the device itself to have adhesive properties.
3Ease of operation
If bone conduction technology is used, then user comfort is improved, but device complexity increases due to additional components
Solution Approach 1:
The patent extracts the adhesive attachment function from the main audio device body and places it on a separate disposable tape component. This extraction simplifies the main device structure, as it no longer needs to integrate adhesive mechanisms, while still achieving the goal of secure skin attachment through the separate tape component.
