Optical Disc Player External Storage Firmware Update
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current optical disc players are limited in updating and expanding content, requiring labor-intensive processes such as returning devices for firmware updates or relying on internet connections, and lack the capability for complex interactions and 3D image presentation.
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 storage and firmware updates, enabling the addition of new content, applications, and enhanced functionality, including interactive games and 3D images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If firmware updates are performed through traditional methods (returning device to retailer or service center), then firmware can be updated, but the process is labor-intensive and time-consuming
Solution Approach 1:
The patent introduces an external storage device as an intermediary carrier to transfer firmware updates. Instead of directly updating the player through complex service center processes, the firmware is first stored on an external storage device, which then serves as a bridge to update the player's internal memory, significantly simplifying the update process and reducing time requirements
Solution Approach 2:
The patent enables preliminary downloading and storage of firmware updates on external storage devices before the actual update is needed. Users can obtain update files in advance and store them on external storage, so when updates are required, the process can begin immediately without waiting for service center appointments or complex download procedures
2Quantity of substance
If internal memory storage is increased to provide more content and applications, then device functionality is enhanced, but device complexity and cost increase
Solution Approach 1:
The patent divides the storage system into two segments: internal memory for essential firmware and core applications, and external storage devices for additional content and applications. This segmentation allows the player to maintain simple internal architecture while accessing expanded functionality through external storage, avoiding the need to increase internal memory capacity
Solution Approach 2:
The patent makes the external storage device serve multiple functions: storing additional content applications, providing firmware updates, and expanding the player's functionality. This multi-functional approach allows a single external storage device to provide content expansion without requiring separate systems for each function, thereby avoiding increased device complexity
3Loss of information
If ROM-based optical discs are used for content delivery, then content can be delivered, but content cannot be changed or updated
Solution Approach 1:
The patent introduces external storage devices as intermediaries between the original ROM content and the player. These external storage devices carry update files and additional content that can be transferred to the player's internal memory, allowing ROM-based discs to be updated without changing the physical disc structure itself
Solution Approach 2:
The patent enables copying of update files and additional content from external storage devices to the player's internal memory. This copying mechanism allows the player to acquire updated content and applications without modifying the original ROM disc, maintaining disc stability while enabling content updates through memory-based copies
