Innovation Solution
A system comprising first and second object devices with high-frequency interfaces and a control system to determine the range of a remote device by transmitting and receiving communication signals via a physical medium, using a device signaling protocol, and utilizing high-frequency circuitry for signal processing and communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wireless transmissions are used to transmit sensor information from sensors to another device, then the system can determine the location of the remote device, but environmental interference adversely affects the reliability and repeatability of the location determining system
Solution Approach 1:
The patent introduces a wired communication intermediary (physical medium such as cables or buses) between the sensors and the processing device. This intermediary shields the signal transmission from environmental interference while still allowing the sensor information to reach the device that determines location, thus resolving the contradiction between reliability and environmental susceptibility.
2Ease of operation
If wireless communications are used for transmitting sensor data, then the system can operate without physical connections, but the vehicle and environment generate interference that adversely affects wireless transmissions
Solution Approach 1:
The patent uses a physical medium as an intermediary transmission channel that is immune to electromagnetic interference generated by the vehicle and environment. This allows the system to maintain ease of operation while eliminating the harmful effects of interference that plagues wireless communications.
3Measurement precision
If signal strength is used as a basis for determining distance between remote device and vehicle, then location can be determined, but the strength of communications drops off as distance increases reducing accuracy
Solution Approach 1:
The patent employs a wired physical medium as an intermediary that does not suffer from signal attenuation with distance in the same way wireless signals do. This intermediary maintains signal strength throughout the transmission path, enabling more precise distance and location measurements without the energy loss that plagues wireless communications.
