Removable Media Player Memory Card for Mobile Phones
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile phones that integrate portable digital media-player functionality are limited by requiring a specific model, preventing users from transferring the media-player between devices, and do not efficiently utilize mobile phone resources such as the battery, screen, communication functionality, and audio system.
Innovation Solution
A digital media device with a reversibly deployable memory card that includes a digital media-player application, allowing playback of media files using the mobile phone's operating system, user controls, visual display, and audio system, and enabling seamless transfer between mobile phones by storing the application on read-only or writable non-volatile memory.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a mobile phone integrates PDMP functionality internally, then the media-player functionality is available, but the user cannot transfer the media-player to another phone and must use a specific model
Solution Approach 1:
The patent divides the PDMP functionality into a separate, removable module (memory card) that can be independently transferred between devices. The media-player application, media library, and DRM components are segmented from the phone's internal memory and placed on a removable card, allowing the user to carry the media-player functionality separately from any specific phone model.
Solution Approach 2:
The memory card is designed to be universally compatible with multiple phone models and operating systems. By placing the PDMP application and necessary components on the removable card rather than embedding them in a specific phone's firmware, the solution achieves multi-functionality across different devices and platforms.
2Reliability
If PDMP functionality is built into a specific phone model, then the media-player works reliably, but the user is locked to that specific model and cannot port it elsewhere
Solution Approach 1:
The removable memory card acts as an intermediary that carries the PDMP application and media library between different phones. Instead of relying on the phone's internal storage, the media-player functionality is mediated through this portable card that can be inserted into any compatible phone, maintaining reliability while enabling portability.
3Adaptability or versatility
If the media-player application is stored on the memory card, then it can be transferred between phones, but the phone's internal resources (battery, screen, audio system) must be utilized
Solution Approach 1:
The patent merges the portable media card with the phone's existing resources. The memory card provides the application and media library, while the phone contributes its battery, screen, audio system, and processing power. This combination allows the transferred application to operate seamlessly using the phone's built-in resources without requiring separate power or display systems.
