Cushioned Support Mount for Electronic Components
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cushioned support mounts for electronic components in miniaturized devices, such as hearing aids, are costly to produce and have inconsistent material properties, making them difficult to assemble and prone to acoustic feedback due to the combination of shock absorption and vibration isolation functions in a single component.
Innovation Solution
A cushioned support system integrated into the device enclosure with elastic and flexible retaining elements, such as thermoplastic elastomers, providing distinct support sections for vibration isolation and shock absorption, allowing for separation of these functions and optimized design for specific components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional rubber mounts are used to hold electronic components, then the component is isolated from mechanical surroundings and protected against impact, but the production cost increases and material properties become inconsistent
Solution Approach 1:
The patent changes the material parameter from traditional rubber to thermoplastic elastomer, which allows for more consistent material properties and easier manufacturing while maintaining the required vibration isolation and shock absorption performance. The thermoplastic elastomer can be precisely controlled during injection molding to achieve uniform material properties throughout the component.
Solution Approach 2:
The patent uses composite material structure by integrating the mounting enclosure and cushioning element as a single integrated component made from thermoplastic elastomer. This composite approach combines the structural support function with the cushioning function in one material system, improving both manufacturing consistency and performance reliability.
2Reliability
If rubber parts are attached to transducers, then shock absorption and vibration isolation are provided, but the assembly process becomes extremely complicated and time-consuming
Solution Approach 1:
The patent merges the mounting enclosure and cushioning element into a single integrated component. The thermoplastic elastomer mounting enclosure is injection molded with built-in cushioning features, eliminating the need to separately attach rubber parts to transducers. This integration dramatically simplifies the assembly process while maintaining all required protective functions.
Solution Approach 2:
The integrated thermoplastic elastomer mounting enclosure serves multiple functions simultaneously: it provides structural support, vibration isolation, shock absorption, and component positioning. This multi-functional design eliminates the need for multiple separate components and assembly steps, improving productivity without sacrificing protective performance.
3Device complexity
If the same material is used for both shock absorption and vibration isolation, then component simplicity is maintained, but the ability to optimize each function separately is lost
Solution Approach 1:
The patent applies local quality by creating different regions within the integrated mounting enclosure with different cushioning characteristics. The thermoplastic elastomer is molded with varying wall thicknesses and density distributions to provide optimized shock absorption in impact-prone areas and optimized vibration isolation in areas requiring frequency damping, all within a single material system.
Solution Approach 2:
The patent segments the mounting enclosure into functional zones with different cushioning properties. The integrated component includes distinct regions for shock absorption and vibration isolation, achieved through varied material distribution and geometric features in the thermoplastic elastomer structure, allowing each function to be optimized independently while maintaining overall component simplicity.
