Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If customized transmission devices are provided at driver's and passenger's seats, then communication between driver and passenger is enabled, but equipment cost increases
Solution Approach 1:
The patent applies universality by using standard mobile phones with existing communication functions (WeChat audio, connecting and calling) instead of customized transmission devices. The mobile phones serve multiple purposes including communication, navigation, and entertainment, eliminating the need for dedicated communication equipment while maintaining communication stability between driver and passenger.
Solution Approach 2:
The system enables self-service communication by allowing driver and passenger to use their own mobile phones with pre-installed communication apps. The头戴式耳机 (headset) connects directly to the mobile phone's audio jack, enabling autonomous communication without requiring specialized transmission devices or external infrastructure.
2Device complexity
If mobile phones with third-party software are used for communication, then equipment cost is reduced, but communication stability deteriorates in remote areas
Solution Approach 1:
The patent introduces the mobile phone as an intermediary device that bridges the communication gap between driver and passenger. The headset acts as a mediator between the mobile phone's audio output and the user's ear, enabling clear communication without relying on network infrastructure. This intermediary approach allows communication to function independently of mobile network coverage.
3Reliability
If driver and passenger physically manipulate mobile phone buttons, then communication functions are accessed, but operation convenience decreases and safety hazards increase
Solution Approach 1:
The patent replaces mechanical button manipulation with voice-based or touchless control mechanisms. The driver can initiate calls, send messages, or access communication functions through voice commands or by simply touching the headset, eliminating the need to physically handle mobile phone buttons while maintaining communication availability and improving safety.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables low-cost, stable, and convenient communication between drivers and passengers without relying on mobile networks, reducing the risk of interruptions and improving safety during travel.
Implementation Method 1
The communication module is capable of transmitting signals with a first wearable device and a second wearable device... The communication module of the centralized control system may be connected to the first wearable device and the second wearable device through short distance wireless communication; wherein the short distance wireless communication includes one of the following: Bluetooth communication, ZigBee communication, Wi-Fi communication, UWB communication, Radio frequency communication, and Infrared communication.

AI summary
A centralized control system in an information interaction system has a communication module capable of transmitting audio signals such as by Bluetooth with a first and a second wearable device. When a user of the first wearable device is on a driver's seat and a user of the second wearable device is on a passenger's seat of a vehicle the centralized control system is capable of transmitting audio signals for the driver and passenger to speak to each other. The information interaction system can include a display screen and/or button for connecting, or rejecting incoming, calls through a mobile terminal. The information interaction system can also have voice command recognition functions, such as to control certain equipment of the vehicle or to make and answer queries through the mobile terminal.
