Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Speaker sound holes in electronic devices, such as laptop computers, are prone to liquid penetration, which can damage internal components.
Innovation Solution
A liquid-blocking structure comprising a bracket body with a guide channel and a liquid collection tank, which directs liquid away from the speaker holes to a collection point, preventing internal damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If speaker holes are provided for sound output, then sound quality is improved, but liquid penetration risk increases
Solution Approach 1:
The speaker hole array is segmented into multiple individual holes rather than a single large opening, reducing the risk of liquid penetration while maintaining sound output quality. The bracket body is also segmented with multiple guide channels corresponding to different speaker hole regions, allowing localized liquid management.
Solution Approach 2:
The bracket body acts as an intermediary structure between the speaker holes and the internal electronic components. It includes guide channels that intercept liquid before it reaches the electronics, and a collection tank that accumulates the collected liquid, preventing direct contact with sensitive components.
2Reliability
If liquid-blocking structure is added to prevent liquid penetration, then reliability is improved, but device complexity increases
Solution Approach 1:
The liquid-blocking function is merged with the existing speaker hole structure by integrating the bracket body directly beneath the speaker array. The guide channels and collection tank are combined into a single unified component rather than separate elements, reducing overall structural complexity while maintaining effective liquid protection.
Solution Approach 2:
The bracket body serves multiple functions: it provides structural support for the speaker array, acts as a liquid collection system with guide channels, and functions as a barrier preventing liquid penetration to internal components. This multi-functionality reduces the need for additional separate protection structures.
3Productivity
If guide channel and collection tank are integrated, then liquid collection efficiency is improved, but manufacturing difficulty increases
Solution Approach 1:
The bracket body is designed with segmented guide channels that correspond to different regions of the speaker hole array. Each guide channel independently directs liquid from its corresponding speaker region to the collection tank, improving liquid collection efficiency while allowing modular manufacturing of the channel structures.
Solution Approach 2:
The collection tank is designed as a flexible or thin-walled structure that can be formed through injection molding or similar processes. This allows the tank to be integrated with the rigid bracket body in a single manufacturing step, reducing assembly complexity despite the integrated design.

AI summary
A liquid-blocking structure for an electronic device is provided in this disclosure. A cover frame of the electronic device has an array of speaker holes. The liquid-blocking structure comprises a bracket body and a pad component. The bracket body is arranged corresponding to the array of speaker holes and includes a guide channel and a liquid collection tank. The pad component is disposed between the cover frame and the bracket body. The bracket body encompasses a range of the array of speaker holes. When liquid flows into the array of speaker holes, the guide channel receives the liquid and guides the liquid to the liquid collection tank.
