Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional securing mechanisms for space access devices, particularly audio transmitting devices, face issues such as easy dislodgment, lack of self-adjustment to internal space shapes, no fluid flow, and inability to modulate audio signal amplitudes or frequencies, leading to discomfort and inadequate fitting range for varying degrees of hearing loss.
Innovation Solution
A securing mechanism with adjustable, outwardly projecting members, such as leaflets, that transition from a relaxed to a securing state, providing differential acoustic impedance and allowing fluid flow, while conforming to the internal space and modulating audio signals, ensuring secure engagement and comfort over extended periods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional securing means (securing rings, compliant outer layers) are used, then the device can be secured in the internal space, but the device is easily dislodged and provides inadequate fitting range
Solution Approach 1:
The securing mechanism employs adjustable outwardly projecting members that can transition between retracted and extended positions, allowing dynamic adaptation to different internal space geometries. This dynamic adjustment capability enables the same device to securely fit various ear canal shapes and sizes while maintaining reliable securing effectiveness.
Solution Approach 2:
The outwardly projecting members can change their physical parameters (extension distance, orientation, contact pressure) to match different internal space characteristics. By adjusting these parameters, the device adapts to varying degrees of hearing loss and different anatomical configurations, expanding the fitting range while ensuring reliable retention.
2Device complexity
If conventional securing means are used, then the device structure is simple, but there is no fluid flow through the device
Solution Approach 1:
The outwardly projecting members are designed as flexible elements that can deform and conform to the internal space geometry. This flexibility allows the creation of sealing surfaces that enable fluid flow control while maintaining a relatively simple overall device structure. The flexible nature of these members provides the necessary manufacturing precision for fluid flow capability without significantly increasing structural complexity.
3Ease of manufacture
If conventional securing means are used, then the device is easy to manufacture, but it does not self-adjust or self-conform to the shape of the internal space
Solution Approach 1:
The outwardly projecting members are designed to automatically self-adjust and self-conform to the internal space shape through their inherent flexibility and mechanical compliance. When inserted, these members naturally deform to match the ear canal geometry without requiring external adjustment mechanisms or complex manufacturing processes. This self-service capability maintains ease of manufacture while providing excellent adaptability.
4Device complexity
If conventional securing means are used, then the device structure is simple, but it does not provide means for modulating audio signal amplitude and frequency
Solution Approach 1:
The outwardly projecting members serve multiple functions: they provide mechanical securing, enable fluid flow control, and facilitate audio signal modulation. By integrating these diverse functions into a single adjustable mechanism, the device achieves audio signal modulation capability without proportionally increasing structural complexity. The same mechanical elements that secure the device also create the acoustic seal necessary for signal modulation.

AI summary
Securing mechanisms for space access devices, such as an audio signal transmitting device, include a plurality of flattened members that are configured to transition from a relaxed state to a securing state when the space access device is inserted into an internal space or opening that has an inside diameter smaller than an outside diameter of the flattened members in the relaxed state. The flattened members securely engage a surface of the internal space and conform to the shape and size of the internal space. An amount of force applied by the flattened members to the surface of the internal space can be tuned by changing a stiffness of a rib supporting the flattened member.
