Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle bus protocols are inadequate for non-safety communications due to low bandwidth and transmission speed, limiting information flow, data security, and remote access while maintaining security against unauthorized parties.
Innovation Solution
A vehicle middleware system that enables real-time forwarding of displayed objects, such as streaming video or applications, between vehicle displays or computational devices within the vehicle using a microprocessor executable module, allowing for improved data stream management and integration, interoperability, and secure networking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If existing vehicle bus protocols are used for non-safety communications, then device complexity is reduced and ease of operation is maintained, but bandwidth and transmission speed are insufficient leading to poor data sharing performance
Solution Approach 1:
The patent segments the communication system into multiple layers: existing vehicle bus protocols handle safety-critical communications while a new middleware layer handles non-safety communications. This allows high-performance data sharing for entertainment and information systems without compromising safety systems, resolving the contradiction by dividing the communication domain into specialized segments.
Solution Approach 2:
The patent introduces a middleware system as an intermediary layer between the existing vehicle bus protocols and the high-bandwidth communication requirements. This middleware acts as a bridge that translates and manages data flows, enabling fast data sharing for non-safety applications while maintaining compatibility with legacy safety-critical bus protocols.
2Speed
If vehicle bus protocols are used for non-safety communications, then security implementation is simpler, but transmission speed and bandwidth are limited
Solution Approach 1:
The patent implements dynamic communication protocols that adapt transmission methods based on data priority and type. High-speed transmissions are used for non-safety entertainment content while safety-critical data uses more conservative, reliable protocols. This dynamic adaptation allows the system to achieve high transmission speeds when needed without permanently increasing protocol complexity.
3Reliability
If existing bus protocols are used for all communications, then system integration is simpler, but remote access and data security are compromised
Solution Approach 1:
The patent applies different security and communication qualities to different parts of the system. Safety-critical systems maintain their existing robust but simple protocols, while non-safety systems benefit from enhanced security features and remote access capabilities. This localized differentiation allows advanced security measures to be implemented only where needed, without increasing overall system complexity unnecessarily.
4Loss of information
If high-bandwidth communication is implemented for non-safety systems, then information flow improves, but energy consumption increases
Solution Approach 1:
The patent implements periodic communication cycles where high-bandwidth data transmission occurs in bursts rather than continuously. Entertainment and information systems use high-speed protocols during active content delivery, then enter low-power states between transmissions. This periodic action pattern maintains excellent information flow when needed while significantly reducing average energy consumption compared to continuous high-speed communication.
