Impact Determination System for Road Structures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies do not provide a method to accurately determine the impact of events, such as construction, on structures like roads, which experience displacement over time due to natural deterioration.
Innovation Solution
An impact determination system that includes a predicted state acquisition means to predict the surface layer state of a structure after an event based on pre-event sensor information, a sensor information acquisition means to acquire post-event sensor information, a state determination means to determine the post-event surface layer state, and an impact determination means to assess the event's impact on the structure by comparing predicted and actual states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If post-event sensor information alone is used to assess structure condition, then measurement simplicity is maintained, but impact determination accuracy deteriorates due to inability to distinguish event-induced changes from natural deterioration
Solution Approach 1:
The system performs preliminary measurement of sensor information before the event occurs to establish a baseline state. This pre-event data is stored and later used for comparison with post-event measurements, enabling accurate isolation of event-induced changes from natural deterioration without requiring complex real-time monitoring systems.
Solution Approach 2:
The system implements a feedback mechanism where pre-event sensor information is fed into the impact determination process alongside post-event information. This feedback loop enables the system to compare actual post-event state with predicted state, accurately determining the event's impact while maintaining system simplicity through algorithmic processing rather than hardware complexity.
2Measurement precision
If pre-event sensor information is measured and used for comparison, then impact determination accuracy is improved, but loss of time increases due to requirement for additional measurement period
Solution Approach 1:
Sensor information is measured and stored in advance before the event occurs, establishing a baseline state without extending the actual impact assessment time. The pre-event measurement captures the structure's initial condition, enabling rapid post-event comparison and acceleration of the determination process.
Solution Approach 2:
The system uses the structure's own pre-event sensor information as the reference baseline, eliminating the need for external reference structures or prolonged monitoring periods. This self-service approach allows the structure to provide its own comparison data, reducing overall measurement time while maintaining accuracy.

AI summary
An impact determination system according to the present invention includes: a memory configured to store instructions; and one or more processors configured to execute the instructions to: acquire a predicted surface layer state of a structure after an event, the predicted surface layer state being sensor information related to a surface of the structure on a ground surface and having been predicted based on pre-event sensor information measured before the event related to a ground of the structure; acquire post-event sensor information measured after the event; determine a post-event surface layer state of the structure based on the post-event sensor information; and determine an impact of the event on the structure based on the predicted surface layer state and the post-event surface layer state.
