Intraoral Bone Conduction Hearing Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Surgical implanted bone anchor hearing aids have a large intraoral device volume due to the placement of electronic and vibration components outside the molar, affecting user experience and requiring complex connections and sealing.
Innovation Solution
The bone conduction hearing device places an electronic assembly and vibration component inside an accommodation space between adjacent molars and the alveolar bone, reducing device size and eliminating the need for complex connections and separate sealing, with the battery optionally located inside or outside this space for convenience and comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the electronic assembly and vibration component are placed outside the molar, then the components can be easily connected and sealed, but the intraoral device volume becomes large affecting user experience
Solution Approach 1:
The electronic assembly and vibration component are nested within the accommodation space formed by adjacent molars and alveolar bone, placing components inside the oral cavity rather than outside, thereby reducing intraoral device volume while maintaining connectability through the accommodation space opening
Solution Approach 2:
The solution transitions from a two-dimensional external placement (outside the molar) to a three-dimensional internal placement (within the accommodation space between molars and alveolar bone), utilizing the available spatial dimension to reduce overall device volume
2Volume of moving object
If the electronic assembly and vibration component are placed inside the accommodation space between molars and alveolar bone, then the intraoral device volume is reduced, but the connection and sealing become more complex
Solution Approach 1:
The accommodation space serves multiple functions: it accommodates the electronic assembly and vibration component, provides a pathway for connection, and enables sealing through its anatomical boundaries, thereby simplifying the overall system despite internal placement
Solution Approach 2:
The accommodation space acts as an intermediary structure that facilitates connection between components placed inside the oral cavity and external elements, while the anatomical boundaries of the space itself provide natural sealing surfaces
