AR Wearable Case Audio Conduit Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable electronic devices, when accommodated in cases, often lose their audio functionality due to the inability to utilize the integrated microphone and speaker components effectively.
Innovation Solution
A case design that includes rotatable support parts and conduits to maintain audio functionality by connecting internal microphone and speaker holes with external holes, allowing sound input and output even when the device is enclosed, along with a processor for mode switching based on external device identification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electronic device is accommodated in a case for protection and portability, then the device is protected from damage and easier to carry, but the audio function (microphone and speaker) cannot be utilized
Solution Approach 1:
The case is segmented into multiple functional components: a body part for protection, support parts for positioning, and conduit parts for audio transmission. This segmentation allows each part to serve its specific function while collectively enabling both protection and audio functionality.
Solution Approach 2:
Conduit parts act as intermediaries between the electronic device's audio components (microphone and speaker) and the external environment. These conduits transmit sound waves through the case structure, enabling audio functions while maintaining device enclosure for protection.
2Reliability
If the case is designed to fully enclose the electronic device for maximum protection, then device security is improved, but audio signal transmission is blocked
Solution Approach 1:
The conduit parts are designed as flexible sound transmission pathways that can be integrated into the case structure. These conduits allow sound waves to pass through the enclosed case while maintaining the protective enclosure, effectively creating selective permeability for acoustic signals.
3Ease of manufacture
If the case structure is simplified for ease of manufacture, then production cost is reduced, but audio function integration becomes difficult
Solution Approach 1:
The case combines multiple functions into a single integrated structure: the body part provides protection, the support parts enable positioning, and the conduit parts facilitate audio transmission. This merging of functions into one structure simplifies manufacturing compared to assembling multiple separate components while maintaining all required functionalities.
Solution Approach 2:
The case is designed as a multi-functional accessory that simultaneously provides device protection, positioning support, and audio transmission capabilities. This universal design allows a single case structure to fulfill multiple purposes without requiring separate components for each function.
