Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the pressure of the bone conduction vibrator in contact with the wearing object is increased to ensure continuous contact and signal transmission, then the signal transmission effect is improved, but it may cause discomfort to the wearing object
Solution Approach 1:
The patent employs an elastic fixing portion that can dynamically adjust its tension state. The elastic band allows the fixing assembly to adapt to different wearing conditions and head shapes, maintaining optimal contact pressure without being excessively tight. This dynamic elasticity resolves the contradiction by enabling the system to self-adjust between ensuring reliable contact and avoiding discomfort.
Solution Approach 2:
The patent changes the physical parameter of the elastic fixing portion by selecting appropriate elastic coefficients and tensioning forces. By controlling the elastic properties and pre-tension within specific ranges, the system achieves the right balance between contact pressure for signal transmission and comfort for the wearing object, thus resolving the contradiction through parameter optimization.
2Object-affected harmful factors
If the pressure of the bone conduction vibrator in contact with the wearing object is decreased to improve comfort, then the wearing comfort is improved, but the signal transmission effect becomes poor
Solution Approach 1:
The elastic fixing portion provides dynamic adaptation, allowing the system to maintain sufficient contact pressure for signal transmission while adapting to comfort requirements. The elasticity enables the assembly to conform to the wearing object's shape without requiring excessive tightness, thus achieving both good signal transmission and comfort.
Solution Approach 2:
By optimizing the elastic coefficient and pre-tension force parameters of the fixing portion, the patent achieves a balance where the contact pressure is sufficient for signal transmission but not excessive to cause discomfort. This parameter optimization resolves the contradiction between comfort and signal transmission effectiveness.
3Stability of the object's composition
If the elastic fixing portion is made tighter to ensure consistent contact pressure, then the signal transmission stability is improved, but the adjustability for different users is reduced
Solution Approach 1:
The fixing portion is segmented into an elastic band with defined tensioning characteristics. This segmentation allows the elastic portion to be designed with specific mechanical properties that provide consistent tension across different sizes and shapes, ensuring stable contact pressure while accommodating user variations through the inherent flexibility of the elastic material.
4Ease of manufacture
If a fixed pressure structure is used to maintain consistent contact, then the manufacturing complexity is reduced, but the ability to precisely adjust pressure for different users is lost
Solution Approach 1:
The patent employs an elastic fixing portion with controllable elastic coefficients and pre-tension forces. By adjusting these physical parameters during manufacturing, the system achieves precise pressure control for different users without requiring complex adjustable mechanisms. This parameter-based approach maintains manufacturing simplicity while enabling pressure adaptability.

AI summary
The present disclosure provides a fixing assembly and a wearing device of a bone conduction vibrator, comprising: an elastic fixing portion, the elastic fixing portion being in a form of a band structure, the elastic fixing portion including a first position and a second position, the first position and the second position being disposed at intervals along a length direction of the elastic fixing portion; and a fixing member, configured to fix the elastic fixing portion around a wearing object, so that the bone conduction vibrator is located between the elastic fixing portion and the wearing object. When the elastic fixing portion surrounds the wearing object and is in a natural state, the fixing member fits into the first position of the elastic fixing portion; when the fixing member fits into the second position, the elastic fixing portion provides the bone conduction vibrator with a pressure acting on the wearing object, and the pressure is within a preset pressure range.
