Behind-Ear Hearing Device Three-Shell Housing Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hearing device designs with two-part housings are complex and expensive, making it difficult to change the color of the lower shell without affecting sensitive electronics and requiring a complex frame, limiting design flexibility and user preference.
Innovation Solution
A hearing device design featuring an upper shell, a first lower shell, and a second lower shell that can be releasably fastened using a frictional connection, allowing for easy assembly and disassembly, and enabling complete or partial color changes without altering the sensitive electronics, with the second lower shell being made of elastic material for a 'click-cover' effect and optional nano-coating for contamination resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a two-part housing design with housing shell halves is used, then the hearing device can be assembled, but the housing becomes complex and expensive to manufacture and modify
Solution Approach 1:
The housing is divided into three independent segments: upper shell, first lower shell, and second lower shell. This segmentation allows each part to be manufactured separately and simplifies the overall structure, enabling easy assembly and disassembly without complex fastening mechanisms.
Solution Approach 2:
The second lower shell is designed to be placed over the first lower shell, with the first lower shell nested inside the second lower shell. This nesting arrangement allows the second lower shell to cover and protect the first lower shell while maintaining a compact overall structure.
2Adaptability or versatility
If the housing shells are fastened against the frame in various shapes or colors, then design customization is possible, but the mounting becomes difficult and expensive
Solution Approach 1:
The housing is segmented into replaceable colored parts (upper shell, first lower shell, second lower shell) that can be independently manufactured in different colors and designs. This allows users to customize the appearance without affecting the internal structure or electronics.
Solution Approach 2:
The design allows for easy replacement of the second lower shell, which can be removed and replaced with a different colored or designed shell. This enables users to change the appearance of the hearing device without replacing the entire housing or affecting the internal components.
3Adaptability or versatility
If only the upper shell is exchanged for color change, then the electronics are protected, but the lower shell remains neutrally colored and the design is compromised
Solution Approach 1:
The lower housing is divided into two separate shells (first lower shell and second lower shell), allowing the outer second lower shell to be replaced for color customization while the first lower shell remains in place to protect the electronics. This eliminates the need for a complex frame construction.
Solution Approach 2:
The first lower shell is nested inside the second lower shell, with the electronics mounted in the first lower shell. The second lower shell can be replaced for color changes while the first lower shell with electronics remains protected inside, achieving complete color customization without complex frame construction.
4Device complexity
If a complex frame is used to mount housing shells, then the housing can be assembled, but the device becomes expensive and difficult to modify
Solution Approach 1:
The housing is segmented into three independent parts that can be assembled without a complex frame. The upper shell, first lower shell, and second lower shell can be joined using simple connection methods, eliminating the need for expensive and complex frame structures.
Solution Approach 2:
The housing design allows for dynamic reconfiguration and easy modification. The second lower shell can be easily removed and replaced, and the upper shell can be exchanged, enabling flexible modifications without requiring complex frame construction or high manufacturing costs.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates simple and cost-effective color changes and design customization, including two-tone combinations, while protecting sensitive electronics and preventing the device from appearing larger, with the option of individualized shape adjustment and easy cleaning.
Implementation Method 1
the second lower shell and the first lower shell are releasably connected to one another by means of a frictional connection
Implementation Method 2
This can be effected by means of an elastic deformation of the second lower shell
Implementation Method 3
optional nano-coating for contamination resistance
