Innovation Solution
A system utilizing a mobile data processing device as a network node to translate control commands from a motion detection device into instructions for the infotainment system via different communication interfaces, such as Bluetooth Low Energy and wireless fidelity, allowing for versatile control and feedback without requiring tailored interfaces on the infotainment system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If infotainment systems use limited communication interfaces, then system complexity is reduced, but adaptability to different control devices is worsened
Solution Approach 1:
The mobile device acts as an intermediary between the motion detection device and the infotainment system. It receives control commands from the motion detection device via first communication interface, translates them into appropriate instructions, and transmits them to the infotainment system via second communication interface. This mediator approach allows the infotainment system to maintain simple interfaces while achieving high adaptability to various control devices.
2Device complexity
If motion detection devices use limited communication interfaces, then device complexity is reduced, but ease of operation with infotainment systems is worsened
Solution Approach 1:
The mobile device serves as a mediator that bridges the communication gap between the simple motion detection device and the infotainment system. It handles the complexity of interface compatibility, protocol translation, and command mapping, allowing the motion detection device to remain simple while maintaining ease of operation with the infotainment system.
3Adaptability or versatility
If infotainment systems provide multiple communication interfaces, then adaptability to external devices is improved, but device complexity is worsened
Solution Approach 1:
Instead of equipping the infotainment system with multiple communication interfaces, the system uses a mobile device as an intermediary that handles multiple interface protocols. This approach achieves high adaptability while keeping the infotainment system architecture simple, as the interface complexity is shifted to the mobile device.
4Speed
If control commands are directly transmitted between motion detection device and infotainment system, then transmission speed is improved, but adaptability to different device pairs is worsened
Solution Approach 1:
The mobile device acts as a translation intermediary that receives control commands from various motion detection devices and converts them into standardized instructions for the infotainment system. This maintains fast transmission by using direct wireless communication while achieving broad device compatibility through protocol translation at the mobile device level.
