Dangerous Goods Route Management Under Point-Value Limits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge lies in managing the quantity and type of dangerous goods carried by vehicles or containers to adhere to regulatory limits, particularly in scenarios where picking up additional goods could exceed maximum allowable thresholds, leading to increased costs and customer dissatisfaction due to potential route alterations or delays.
Innovation Solution
A system that calculates a 'point value' for dangerous goods based on type and quantity, allowing for real-time tracking and dynamic route adjustments to ensure the total point value remains below a predetermined threshold, thereby avoiding the need for additional vehicles or delayed pickups by recalculating delivery routes as goods are delivered and picked up.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the vehicle/container picks up additional items containing dangerous goods along the scheduled delivery route, then the quantity of dangerous goods increases, but the total volume/quantity may exceed the maximum allowable volume/quantity
Solution Approach 1:
The system dynamically recalculates the total volume/quantity of dangerous goods on the vehicle/container in real-time as items are picked up and delivered. The routing system adjusts delivery routes dynamically based on current cargo composition and regulatory limits, allowing flexible adaptation to changing conditions while maintaining compliance.
Solution Approach 2:
The system continuously monitors the volume/quantity of dangerous goods carried and provides feedback to the routing system. This feedback loop enables the system to identify when the maximum allowable volume/quantity is approaching and automatically adjust routes or dispatch additional vehicles before violations occur.
2Reliability
If the vehicle/container cannot pick up items containing dangerous goods due to volume/quantity limits, then regulatory compliance is maintained, but additional vehicles need to be dispatched or pickups delayed
Solution Approach 1:
The system proactively monitors the volume/quantity of dangerous goods and predicts when regulatory limits will be reached. By taking preliminary action to adjust routes or dispatch additional vehicles before limits are exceeded, the system maintains compliance while minimizing disruptions to delivery operations.
Solution Approach 2:
The routing system acts as an intermediary between cargo management and delivery operations. It coordinates between the need to maintain regulatory compliance and the desire to maintain efficient delivery operations by optimizing route assignments and vehicle dispatch decisions.
3Reliability
If the system monitors and manages dangerous goods volume/quantity in real-time, then regulatory compliance is ensured, but system complexity increases
Solution Approach 1:
The routing system performs multiple functions: it optimizes delivery routes, tracks dangerous goods volume/quantity, ensures regulatory compliance, and coordinates vehicle dispatch. By consolidating these functions into a single multi-functional system, the patent reduces overall system complexity while maintaining comprehensive monitoring and compliance capabilities.

AI summary
As deliveries of items containing dangerous goods are made from a vehicle/container, systems update stored information to reflect the reduced number of points of dangerous goods currently on the vehicle/container. Conversely, when the vehicle/container picks up dangerous goods, the systems update the information to reflect the increased number of points of dangerous goods currently on the vehicle/container. The systems identify potential delivery routes, such that the vehicle/container may deliver items containing dangerous goods prior to picking up new items, so as to maintain the total points of dangerous goods on the vehicle/container below a predetermined threshold.
