Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices are susceptible to damage or malfunction when moisture enters through openings, particularly affecting speakers and microphones, leading to potential circuit damage or corrosion.
Innovation Solution
The electronic device utilizes multiple speakers to identify moisture introduction and guides a tilting direction for moisture discharge, enabling efficient moisture removal through controlled speaker operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple speakers are used to detect moisture, then moisture detection precision is improved, but device complexity increases
Solution Approach 1:
The speaker serves dual functions: it acts as both an audio output device and a moisture detection sensor. By utilizing the existing speaker components (voice coil, diaphragm, air cavity) for both sound production and moisture sensing, the patent eliminates the need for separate detection hardware, thereby improving moisture detection precision without increasing device complexity
Solution Approach 2:
The speaker system performs self-diagnosis by monitoring its own operational parameters (impedance changes, sound output variations) to detect moisture presence. This self-service approach allows the device to detect moisture using its existing components without requiring additional external sensors or complex detection systems
2Reliability
If moisture discharge function is enabled, then reliability is improved, but device complexity increases
Solution Approach 1:
The patent converts the harmful effect of moisture accumulation into a beneficial discharge mechanism. By detecting moisture through speaker performance degradation and then using the speaker system itself to generate vibrations and heat that evaporate and expel the moisture, the harmful moisture becomes the trigger for its own removal, improving reliability without adding complex discharge hardware
Solution Approach 2:
The moisture discharge function operates periodically based on detection results. When moisture is detected, the system activates the speaker to perform discharge operations at specific intervals, allowing moisture to be gradually evaporated and expelled through controlled periodic cycles rather than requiring continuous complex intervention
