Abnormality Notification Routing for Vehicles and Drones
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for notifying abnormalities in vehicles and drones fail to appropriately target notifications based on the type of abnormality, leading to unnecessary communication loads and ineffective external notifications.
Innovation Solution
A notification apparatus and method that detects abnormalities and determines appropriate notification destinations based on the type of abnormality, generating tailored notification messages to be sent via narrow and wide area communication units, ensuring relevant parties are informed without overwhelming unaffected parties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If communication output is increased to reliably notify other vehicles of abnormalities, then notification reliability is improved, but communication amount and processing load on receiving side increase
Solution Approach 1:
The patent applies local quality by differentiating notification strategies based on abnormality type. Safety abnormalities (affecting vehicle control) trigger notifications to vehicles in the periphery area, while security abnormalities (external attacks) trigger notifications to a broader wide area. This localized differentiation ensures reliable notification to affected parties without unnecessarily increasing communication load on all receiving vehicles.
Solution Approach 2:
The patent changes the parameter of notification scope based on abnormality type. By detecting whether an abnormality is a safety or security type, the system dynamically adjusts the notification area parameter - using periphery area for safety abnormalities and wide area for security abnormalities. This parameter change resolves the contradiction by optimizing communication amount according to the specific abnormality scenario.
2Loss of information
If notification is sent to all vehicles regardless of abnormality type, then notification coverage is improved, but processing load on receiving vehicles increases
Solution Approach 1:
The patent implements local quality by creating different notification zones based on abnormality type. For safety abnormalities, notifications are limited to the periphery area where affected vehicles are most likely to be located. For security abnormalities, notifications are sent to the wide area. This approach maintains comprehensive notification coverage for each abnormality type while minimizing unnecessary processing load on vehicles outside the relevant notification zone.
3Productivity
If notification scope is limited to periphery area only, then communication efficiency is improved, but notification coverage for remote partners deteriorates
Solution Approach 1:
The patent applies dynamics by making the notification scope flexible and adaptive rather than fixed. The notification area dynamically changes based on the detected abnormality type - expanding to wide area for security abnormalities and contracting to periphery area for safety abnormalities. This dynamic adjustment resolves the contradiction by optimizing both communication efficiency and notification coverage according to the specific abnormality scenario.

AI summary
A notification apparatus comprises a detection means for detecting an abnormality in a mounting apparatus with the notification apparatus mounted therein, and a notification means for notifying an external notification destination decided in accordance with the abnormality detected by the detection means of the abnormality.
