Solution Overview
Problem
Existing systems and devices, such as in-vehicle head units and medical devices, lack the ability to easily access external networks and receive frequent software updates, limiting their network access and multimedia capabilities due to processing limitations and device-specific software constraints.
Innovation Solution
A system that utilizes mobile devices to provide extended network access and multimedia functionality to external systems by allowing third-party applications to be executed on these devices using web and native technologies, with a configurable infrastructure for application delivery and rendering, supporting different devices with varying capabilities, and providing a common programming interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If external systems use device-specific software with limited processing capability, then device simplicity and cost-effectiveness are maintained, but network access capability and software update frequency are limited
Solution Approach 1:
The patent introduces a mobile device as an intermediary between the external system and the network. The mobile device handles complex network communication, web browsing, and application execution, while the external system remains simple and focused on its core function. This mediator approach allows the external system to access networks and run diverse applications without adding complexity to its own architecture.
Solution Approach 2:
The mobile device serves multiple functions: it acts as a network gateway, application server, rendering engine, and user interface provider. By consolidating these diverse functions in a single universal device, the system avoids the need to build multiple specialized components, thereby maintaining simplicity in the external system while achieving high adaptability and network access capability.
2Productivity
If external systems execute device-specific software, then hardware requirements are reduced, but software update frequency and ease of updates are limited
Solution Approach 1:
Instead of updating software on the external system's hardware, the patent uses a mobile device to copy and execute application software. Applications are downloaded, installed, and updated on the mobile device's operating system, which then renders and streams them to the external system. This copying approach allows frequent software updates without modifying the external system's hardware or embedded software.
Solution Approach 2:
The system dynamically adapts software updates by leveraging the mobile device's flexible operating system environment. Applications can be installed, updated, removed, or modified at any time on the mobile device, and these changes are immediately reflected in the external system's functionality. This dynamic approach contrasts with static embedded software that requires complex reprogramming and hardware modifications for updates.
3Adaptability or versatility
If external systems access networks with limited software, then device cost is reduced, but multimedia performance and network access functionality are limited
Solution Approach 1:
The mobile device acts as an intermediary that handles all multimedia processing, web browsing, and network communication. The external system simply displays content rendered by the mobile device. This separation allows high-performance multimedia capabilities to be achieved through the mobile device's powerful processor, graphics hardware, and operating system, while the external system remains simple and cost-effective.
Solution Approach 2:
The patent replaces the need for complex hardware and embedded software in the external system with a software-based solution running on the mobile device. Web technologies (HTML5, JavaScript, CSS) and native mobile applications substitute for dedicated multimedia hardware, allowing flexible, upgradable multimedia performance without adding physical complexity to the external system.
