Optical Disc Player External USB Port Firmware Update
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current optical disc players are limited in updating and expanding content, requiring labor-intensive processes for firmware updates and lacking the capability for complex interactions or 3D presentations, with restricted storage for additional data.
Innovation Solution
An optical disc player with a standard digital port for coupling to an external device, such as a USB thumb drive, allowing for data transfer and firmware updates, enabling enhanced functionality, additional content, and interactive features by using external data storage to augment or replace disc content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If firmware updates are performed through traditional mechanisms (returning to retailer, using update discs, or online download), then firmware can be updated, but the process is labor intensive and inconvenient for users
Solution Approach 1:
The patent introduces an external storage device as an intermediary medium between the firmware source and the disc player. The external storage device stores firmware update files and interfaces with the disc player through a standard port, enabling users to update firmware by simply connecting the storage device without needing to return to retailers, use special update discs, or rely on online connections. This intermediary approach simplifies the update process while maintaining reliable firmware updating capability.
2Reliability
If optical discs use ROM structure, then content can be reliably stored, but content cannot be changed or updated
Solution Approach 1:
The patent segments the content storage system into two parts: the original ROM optical disc that provides stable, unchangeable content storage, and an external storage device that provides updateable content. The disc player can load content from either source or combine them, allowing the system to maintain the reliability of ROM storage while gaining the adaptability of updatable content through the external storage device.
3Device complexity
If disc players have limited internal storage, then device complexity is reduced, but complex manipulations and additional content cannot be supported
Solution Approach 1:
The patent makes the external storage device serve multiple functions: storing additional content, providing firmware updates, and enabling complex manipulations. By using a universal external storage device that can be connected through a standard port, the system gains enhanced content manipulation capability and additional storage capacity without increasing the complexity of the disc player's internal storage architecture.
