Solution Overview

Problem

Existing in-vehicle emergency report systems face delays in transmitting emergency report signals due to the need to disconnect wireless communications links for non-emergency usage, leading to delayed emergency reporting.

Innovation Solution

An in-vehicle emergency report apparatus that secures a wireless communications resource for emergency reports when a collision possibility is detected and an emergency report is not in progress, allowing for prompt transmission of emergency signals without disconnecting existing links.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the wireless communications device disconnects the wireless communications link for other usage to transmit emergency report signal, then the emergency report signal can be transmitted via mobile communications network, but the transmission is delayed by the time needed to disconnect and reconnect links

Engineering Contradiction:
Improveemergency report transmission reliabilityVSAvoidemergency report transmission delay
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The control circuit pre-secures a wireless communications resource for emergency report before an actual emergency occurs. When a collision possibility is detected and no emergency report is being executed, the system proactively reserves the communication resource, so that when an emergency trigger occurs, the transmission can begin immediately without delay for link disconnection or resource allocation.

Inventive Principle:
Principle #10Preliminary action

2Productivity

If the wireless communications device maintains continuous wireless communications for other usage, then communication resources are utilized efficiently, but emergency report signal transmission is delayed when collision occurs

Engineering Contradiction:
Improvewireless communications resource utilizationVSAvoidemergency report transmission speed
Core Design Contradiction:
ProductivityVSSpeed

Solution Approach 1:

The wireless communications resource allocation is made dynamic rather than static. The control circuit monitors collision possibility and emergency report status, and dynamically adjusts the wireless communications resource state between secured and released. This allows the system to optimize for normal communication efficiency while ensuring rapid emergency response when needed.

Inventive Principle:
Principle #15Dynamics

3Loss of time

If the control circuit secures wireless communications resource when collision possibility is detected and no emergency report is executing, then emergency report signal can be transmitted promptly, but wireless communications resources are occupied during non-emergency periods

Engineering Contradiction:
Improveemergency report transmission delayVSAvoidwireless communications resource occupation
Core Design Contradiction:
Loss of timeVSLoss of energy

Solution Approach 1:

The control circuit continuously monitors the execution status of emergency reports and the detected collision possibility. Based on this feedback, it dynamically releases the secured wireless communications resource when no emergency is being executed and no collision threat exists, and re-secures it when conditions warrant. This feedback mechanism ensures resources are occupied only when necessary for safety or imminent emergency response.

Inventive Principle:
Principle #23Feedback

AI summary

When determining a collision possibility of a vehicle while an emergency report is not being executed, an in-vehicle emergency report apparatus secures a wireless communications resource by one of the following: (i) Rejecting a connection request for connecting a wireless communications link from a navigation system to a wireless communications device in respect of another use other than an emergency report; (ii) Disconnecting the wireless communications link connected by the wireless communications device according to a connection request from the navigation system in respect of another use other than an emergency report; (iii) Notifying the navigation system of prohibition of connecting the wireless communications link by the wireless communications device in another use other than an emergency report; and (iv) Restricting a connection band of the wireless communications link in the wireless communications device in respect of another use other than an emergency report from the navigation system.
