Wireless USB Storage for Offline Media Playback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Devices without wireless communication interfaces, such as high-fidelity channels and optical players, face challenges in accessing and playing media content due to limited local storage capacity and inability to connect directly to cloud computing services, resulting in slow content delivery and compromised ergonomics.
Innovation Solution
A removable storage device equipped with a processor, non-volatile flash memory, and a USB connector, along with a wireless communication interface, detects incomplete media content and establishes a connection with a remote gateway to download complementary content, allowing seamless playback by concatenating incomplete and complete media content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If cloud computing services are used to store media content, then storage capacity is improved, but access speed deteriorates due to download time delays
Solution Approach 1:
The system pre-loads media content from cloud storage into the portable storage device before playback is needed. The processor detects when media content is requested and automatically downloads it to local storage in advance, eliminating wait time during actual playback and resolving the contradiction between cloud storage capacity and access speed.
2Adaptability or versatility
If devices are equipped with wireless communication interfaces to access cloud services, then connectivity is improved, but device complexity increases
Solution Approach 1:
The wireless communication interface and cloud access functionality are extracted from the main playback device and placed into a separate portable storage device. This allows the main device to remain simple without wireless interfaces while still gaining cloud connectivity capabilities through the portable device's USB connection.
3Speed
If media content is stored locally on devices, then playback speed is improved, but storage capacity is limited
Solution Approach 1:
A portable storage device acts as an intermediary between cloud storage and the main playback device. It receives media content from cloud services via USB connection and stores it locally, enabling fast playback from local storage while bypassing the storage capacity limitations of the main device.
