Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience when adding, replacing, or deleting contents data on a portable player connected to a broadcasting receiving apparatus, as they need to frequently detach and reconnect the player from the apparatus to a personal computer.
Innovation Solution
A broadcasting receiving apparatus with connectors for both portable players and personal computers, including a switching control unit that allows data transfer and mode switching between reproduction and communication modes without requiring the player to be detached, enabling data management directly while connected.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the portable player is connected to the broadcasting receiving apparatus for audio/video output, then the user can enjoy high-quality playback, but the user cannot add or manage contents data without detaching and reconnecting to the PC
Solution Approach 1:
The broadcasting receiving apparatus serves as an intermediary device between the portable player and the PC. It includes a USB connector for PC connection and can establish communication pathways that allow the PC to access and manage contents data on the portable player without requiring direct physical connection between the PC and portable player, thus eliminating the need for repeated detachment and reconnection operations
Solution Approach 2:
The broadcasting receiving apparatus is designed with multi-functionality: it can simultaneously function as an audio/video output device for the portable player and as a communication bridge for contents data management. The device includes both audio signal processing capabilities and USB communication interfaces, allowing it to handle both playback functions and data management functions through a single connection setup
2Adaptability or versatility
If the portable player is disconnected from the broadcasting receiving apparatus to connect to the PC for contents management, then data transfer can be performed, but the user loses access to high-quality audio/video playback

AI summary
The portable player is connected to a first connector, and the PC is connected to a second connector. A first connection detecting unit detects whether the portable player is connected, and a second connection detecting unit detects whether the PC is connected. A central processing unit (CPU) switches to a reproduction mode in which an audio signal based on audio data reproduced by the portable player is supplied by the audio processing unit to the speaker, or a PC communication mode in which the portable player and the PC are connected to be in a state in which they can communicate with each other.
