Silicone Waterproof Structure for Inclined Headset Housings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing waterproof structures for headsets are limited in reducing overall size and ensuring effective sealing, particularly in TWS designs, where space efficiency and manufacturing convenience are crucial without compromising functionality.
Innovation Solution
A waterproof structure featuring a front and rear housing with an inclined coupling and a flexible silicone sealing member, integrally molded with the housing using an insert injection process, which provides enhanced sealing by compressing an insert to form a tight seal between the housings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a sealing member is disposed outside the speaker body to provide waterproofing, then waterproof function is improved, but the overall size of the audio equipment increases
Solution Approach 1:
The sealing member is nested within the speaker body structure rather than being disposed outside. The insert molded sealing member is integrated into the speaker body's internal cavity, allowing the waterproofing function to be achieved without increasing the external dimensions of the audio equipment.
Solution Approach 2:
The sealing member is merged with the speaker body through insert molding, creating an integrated structure where the waterproofing function is combined with the speaker housing. This eliminates the need for separate external sealing components and reduces overall device volume.
2Reliability
If multiple separate components are used to form a waterproof structure, then sealing effectiveness is improved, but manufacturing complexity increases
Solution Approach 1:
The sealing member and speaker body are combined into a single integrated component through insert molding. The process involves placing a pre-formed sealing member insert into a mold, then molding the speaker body material around it, creating a unified structure with enhanced sealing effectiveness while simplifying manufacturing to a single-step process.
Solution Approach 2:
The sealing member is prepared as a pre-formed insert before the main molding process. This preliminary preparation allows the sealing component to be precisely formed with appropriate elasticity and geometry, ensuring effective sealing while the subsequent molding process integrates it seamlessly into the speaker body.
