Vehicular Communication System with Dual Control Circuits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems for vehicles do not provide seamless, hands-free two-way communication between individuals inside and outside a vehicle, limiting convenience and safety.
Innovation Solution
A vehicular communication system comprising a primary control circuit mounted within the vehicle's cab and an external control circuit on the vehicle's exterior, utilizing wireless communication links (e.g., WiFi™ or Bluetooth™ protocols) to enable hands-free operation of personal data devices both inside and outside the vehicle, allowing for audio signal conversion and transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a communication system is provided inside the vehicle cab only, then hands-free operation within the cab is enabled, but communication from the exterior of the vehicle is not supported
Solution Approach 1:
The communication system is segmented into two independent control circuits: a primary control circuit mounted inside the cab and a secondary control circuit mounted on the exterior surface. Each circuit can independently receive and process communications, allowing the system to provide hands-free operation both inside and outside the vehicle without interference between the two functions.
Solution Approach 2:
The secondary control circuit acts as an intermediary that receives communications from external sources and relays them to the primary control circuit inside the cab. This mediator enables exterior communication capability while maintaining the existing interior hands-free system, effectively extending the communication coverage area without compromising the original functionality.
2Ease of operation
If wireless communication links are implemented for hands-free operation, then convenience is improved, but system complexity increases
Solution Approach 1:
Both the primary and secondary control circuits are designed with multi-functionality, capable of receiving communications from multiple sources including mobile phones, personal data assistants, and other portable communication devices. This universal design allows each circuit to handle various communication protocols and devices, reducing the need for separate specialized systems and thereby limiting the increase in overall system complexity.

AI summary
The vehicular communication system is a communication device. The vehicular communication system incorporates a primary control circuit, an exterior control circuit, and a vehicle. The vehicle further comprises a cab and an exterior surface. The primary control circuit mounts within the cab of the vehicle. The external control circuit mounts on the exterior surface of the vehicle. The primary control circuit forms a first wireless communication link with a personal data device. The primary control circuit enables hands free operation of the personal data device within the cab of the vehicle. The primary control circuit forms a second wireless communication link with the external control circuit. The external control circuit enables hands free operation of the personal data device from the exterior of the vehicle.
