In-Vehicle Imaging Call Routing by Impact Severity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing in-vehicle imaging devices face challenges in efficiently routing emergency calls to appropriate call centers based on the severity of an accident or detected conditions, leading to potential overload and difficulty in handling diverse call types.
Innovation Solution
An in-vehicle imaging device equipped with an impact detecting unit to differentiate between high and low-impact events, and an operation detecting unit to prioritize call routing to specific call centers based on user input, ensuring appropriate connection to either emergency or non-emergency services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all calls (accident and non-accident) are routed to the same call center, then call center coverage is maintained, but call center burden increases and connection reliability decreases
Solution Approach 1:
The patent segments call routing into two distinct paths: high-priority routing for accident calls (impact ≥ threshold) and low-priority routing for non-accident calls (impact < threshold). This segmentation separates emergency traffic from non-emergency traffic, ensuring that accident calls receive immediate attention while non-accident calls are handled during available capacity, thereby improving connection reliability without overwhelming the call center.
Solution Approach 2:
The patent changes the parameter of call priority by using impact magnitude as a classification criterion. Calls are transformed from a single queue into two priority levels based on the detected impact parameter. This parameter-based differentiation allows the system to dynamically adjust routing behavior, improving reliability for critical calls while managing overall call center load.
2Ease of operation
If automatic connection is used for all calls, then user operation simplicity is improved, but call center burden increases due to lack of call type differentiation
Solution Approach 1:
The system performs self-service by automatically detecting impact magnitude and determining call priority without requiring user input. The impact detection unit and connection processing unit work together to autonomously classify calls and select appropriate routing paths. This self-service mechanism maintains ease of operation while preventing call center overload by filtering non-accident calls from the emergency queue.
3Productivity
If impact-based priority routing is implemented, then call center burden is reduced, but device complexity increases
Solution Approach 1:
The in-vehicle imaging device performs multiple functions: it serves as both an impact detection system and a call routing system. The connection processing unit integrates both impact analysis and call management capabilities, allowing the same device to monitor vehicle conditions and automatically initiate appropriate calls. This multi-functionality improves call handling efficiency without requiring separate dedicated systems.

AI summary
An in-vehicle imaging device includes an impact detecting unit configured to detect an impact on a vehicle, a connection processing unit configured to connect to a first phone contact when the impact detected by the impact detecting unit is equal to or greater than a predetermined magnitude and to set a second phone contact as a destination of a connection when the impact is less than the predetermined magnitude, and an operation detecting unit configured to detect a user's operation. The connection processing unit connects to the second phone contact when the impact is less than the predetermined magnitude and the operation detecting unit detects an operation for connecting to a phone contact.
