Hearing Aid Eyeglass Adapter Cable Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for integrating hearing aids with eyeglasses face challenges in cable adjustment, as the electrical cable length is fixed, leading to suboptimal placement and aesthetics due to either being too short or too long, causing discomfort and visibility issues.
Innovation Solution
A spectacle sleeve with a recess and a conduit that forms a trough-like structure, allowing the cable to be pinched at multiple points, enabling adjustable cable length by cutting the sleeve to fit the user's profile, ensuring the cable is neither too short nor too long, and maintaining aesthetics by routing it above the tragus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed-length cable is used in the hearing aid, then the device structure is simple and manufacturing is easy, but the cable cannot be adjusted to fit different user profiles, resulting in suboptimal placement and aesthetics
Solution Approach 1:
The sleeve is designed as a segmented structure with a conduit that has variable cross-section along its length, creating multiple pinching positions for the cable. This segmentation allows the cable to be secured at different locations within the sleeve, providing adjustable effective cable length while maintaining a single integrated sleeve component.
Solution Approach 2:
The conduit within the sleeve has non-uniform cross-sectional dimensions, with the distance between opposite walls varying at different positions. This local variation in geometry creates specific pinching zones where the cable can be secured, allowing customization of cable length without requiring multiple different sleeves.
2Reliability
If the cable is too short, then the device structure is simple, but the earpiece cannot be placed perfectly in the user's ear, causing discomfort
Solution Approach 1:
The sleeve design provides dynamic adaptability by allowing the cable to be pinned at different positions along the conduit's length. This enables the effective cable length to be adjusted to match the specific distance from the hearing aid body to the user's ear canal, ensuring reliable earpiece placement for different user profiles.
3Ease of operation
If the cable is too long, then the cable can reach the ear, but it hangs along the ear which is unsightly and inconvenient for the user
Solution Approach 1:
The sleeve is pre-configured with a conduit that has predetermined pinching positions at optimal locations. This preliminary structuring allows the cable to be secured at the correct position to prevent hanging along the ear, achieving proper cable routing without requiring post-installation adjustments or additional components.
4Adaptability or versatility
If a fixed cable length is used, then manufacturing is simple, but the cable cannot be concealed properly above the tragus, affecting user discretion
Solution Approach 1:
The sleeve is designed as a universal component that can accommodate different cable lengths through its variable-cross-section conduit. A single sleeve design serves multiple functions by allowing cables of different effective lengths to be secured at different pinching positions, making it adaptable to various user profiles while maintaining simple manufacturing processes.

AI summary
The invention relates to a temple tip (15) for spectacles intended for containing a portion of a hearing aid near the ear of the user wearing said spectacles, said temple tip including a recess (19), capable of receiving and securely holding the aforementioned portion of the hearing aid, and being drilled with a duct (14) extending away from the recess and opening at the lower surface (16) of said temple tip, said duct (14) being intended for receiving the wire (10) connecting the power source (4), housed alone or with the transmitter in the recess (19), to the other portion of the hearing aid arranged in the auditory canal of the user. Such a temple tip is characterised in that the duct (14) extends in the form of a trough (17) made in the lower surface (16) of the temple tip, the width of the opening on the outside (11) of said trough being smaller in at least two locations than the diameter of the wire (10) such as to offer at least two positions for clamping the wire (10) between the two converging edges (12) of said opening (11).
