Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional hardwired security systems are used to connect to individual vehicle devices, then reliable control and alarm functions are achieved, but wiring complexity and system installation difficulty increase significantly
Solution Approach 1:
The patent replaces the mechanical hardwired connection system with a wireless communication system. The remote function device communicates with vehicle devices through wireless transceivers and data communications bus, eliminating the need for physical wire connections between the security system and individual vehicle components while maintaining reliable control and alarm functions
Solution Approach 2:
The patent introduces a data communications bus as an intermediary between the remote function device and vehicle devices. This bus serves as a communication medium that allows the security system to interact with multiple vehicle devices without direct hardwired connections, thereby reducing wiring complexity while maintaining system reliability
2Reliability
If hardwired connections are made by splicing into vehicle wiring harnesses, then direct control of vehicle devices is achieved, but installation time and labor costs increase
Solution Approach 1:
The patent replaces mechanical splicing operations with wireless communication. The remote function device establishes communication with the vehicle through wireless transceivers and interfaces with the data communications bus, eliminating the need for technicians to physically splice into existing wiring harnesses and significantly reducing installation time
Solution Approach 2:
The patent creates a universal interface that can work with multiple vehicle models and manufacturers through the standardized data communications bus protocol. This universal approach allows the same remote function device to control various vehicle devices across different vehicle platforms without requiring model-specific hardwired connections, reducing both installation time and complexity
3Adaptability or versatility
If multiple T-harnesses and connectors are used to interface with vehicle devices, then adaptability to different vehicle configurations is achieved, but the number of components and wiring complexity increase
Solution Approach 1:
The patent implements a universal data communications bus interface that can communicate with multiple different vehicle devices and protocols through a single wireless connection point. This universal interface eliminates the need for multiple T-harnesses and connectors while maintaining adaptability to different vehicle configurations through software-based protocol compatibility
Solution Approach 2:
The patent extracts the communication interface from the physical wiring domain and places it in the wireless communication domain. By removing the need for physical T-harnesses and connectors and replacing them with wireless transceivers that interface with the data communications bus, the system maintains vehicle configuration adaptability while significantly reducing the number of physical components

AI summary
A remote function control system is for a vehicle including a data communications bus extending throughout the vehicle and coupled to a plurality of vehicle devices, and a wired vehicle electrical power system. The system may include a remote function device coupled to the data communications bus and including an interior wireless device to wirelessly communicate within the vehicle, an exterior wireless device to wirelessly communicate with a remote control device away from the vehicle, and a controller coupled to the interior and exterior wireless devices to permit communication between the remote control device and at least one vehicle device coupled to the vehicle data communications bus. The system may further include a wireless security sensor positioned within the vehicle and coupled to the wired vehicle electrical power system, with the wireless security sensor being configured to wirelessly communicate within the vehicle to the interior wireless device.
