Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices face issues with high production costs, cumbersome assembly processes, misalignment of parts leading to poor sealing, and interference from ambient noise affecting acoustic performance due to inadequate pressing force.
Innovation Solution
A sealing mechanism comprising a sealing body and a sealing ring with differing hardness levels, where the sealing ring is softer than the body, integrated as a one-piece member, providing improved sealing and acoustic features through reduced part count and simplified assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple parts are used for assembling the electronic device, then the sealing capability can be enhanced, but the production cost increases and the assembly process becomes cumbersome
Solution Approach 1:
The patent combines multiple sealing components (sealing body, sealing ring, and pressing structure) into a single integrated sealing mechanism. This merging reduces the number of parts while maintaining the sealing capability, directly resolving the contradiction between enhanced sealing and reduced device complexity.
2Reliability
If multiple parts are used for assembling the electronic device, then the sealing capability can be enhanced, but the assembly process becomes cumbersome and time-consuming
Solution Approach 1:
By integrating the sealing body, sealing ring, and pressing structure into one unit, the assembly process is simplified from multiple discrete assembly steps to a single installation operation, significantly improving productivity while maintaining sealing effectiveness.
3Reliability
If pressing force is increased to improve air tightness, then the sealing capability is enhanced, but the acoustic performance is degraded
Solution Approach 1:
The sealing ring is designed with localized soft material properties at the sealing interface to achieve effective sealing with minimal pressing force, while the overall structure maintains acoustic performance. This local quality differentiation resolves the contradiction between air tightness and acoustic performance.
Solution Approach 2:
The patent changes the material parameter (hardness) of the sealing ring to be softer than the sealing body, enabling the sealing ring to deform and conform to the acoustic membrane, achieving effective sealing with reduced pressing force that does not degrade acoustic performance.
4Reliability
If multiple parts are assembled together, then the sealing capability can be improved, but misalignment between parts occurs leading to poor sealing
Solution Approach 1:
By combining the sealing body and sealing ring into an integrated structure with pre-established positional relationships, the patent eliminates alignment errors that would occur during assembly of separate parts, ensuring precise positioning and effective sealing.

AI summary
An electronic device includes a chassis, a voice receiving unit, an acoustic membrane, and a sealing mechanism. The chassis has a through hole. The sealing mechanism includes a sealing body and a sealing ring. The sealing body has an accommodation portion and a channel. One of two ends of the channel is in communication with the accommodation portion, and the other end has a first opening. The accommodation portion accommodates the voice receiving unit. The sealing ring is between the sealing body and the acoustic membrane, and has a penetration hole. The penetration hole, the through hole and the first opening correspond to each other. A ring hardness of the sealing ring is less than a body hardness of the sealing body.
