Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing systems for dispensing urea solutions in diesel vehicles face challenges such as deposits in exhaust pipes, complicating the management of containers, and impracticality in transporting large containers to remote locations, especially where service stations are scarce, making it difficult to distribute urea solutions with or without additives effectively.
Innovation Solution
A transportable container system that includes separate compartments for urea solution and additives, with fluidic circuits and valves allowing for mixing and distribution of urea solutions with or without additives at the point of use, enabling flexible and efficient distribution without the need for large containers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the additive is added to the urea solution at a production facility, then the urea solution can be prepared with additives, but the management of containers for both urea solution and additive becomes complicated
Solution Approach 1:
The system divides the urea solution storage into separate containers: a first container for pure urea solution and a second container for additive. This segmentation allows independent management of each substance while maintaining the ability to mix them when needed, thereby simplifying container management while ensuring solution quality.
2Reliability
If large containers are transported to remote locations, then urea solution with additives can be distributed, but transporting large containers to remote, hard-to-reach locations becomes impractical
Solution Approach 1:
The system uses multiple smaller containers (first container for urea solution, second container for additive) instead of one large container. These smaller containers can be easily transported to remote locations and then combined to provide the full distribution capability, thus improving transportability while maintaining distribution capability.
Solution Approach 2:
The system combines the contents of the first container (urea solution) and second container (additive) at the point of use through fluid circuits and mixing mechanisms. This merging allows the system to provide the full functionality of a large container system while using smaller, more transportable individual containers.
3Adaptability or versatility
If urea solution is distributed in areas with few or no gas stations, then remote area distribution is enabled, but the infrastructure requirement of gas stations is eliminated making distribution more difficult
Solution Approach 1:
The system is designed to be self-contained with all necessary components (urea solution container, additive container, mixing mechanism, distribution outlets) integrated into a single unit that can operate independently without external gas station infrastructure. This self-service capability enables distribution in remote areas while managing system complexity through integration.
4Adaptability or versatility
If small quantity of urea solution is prepared for individual consumers, then personalized distribution is enabled, but the preparation of small quantities becomes more complex
Solution Approach 1:
The system incorporates adjustable fluid circuits and valves that allow dynamic control of the mixing ratio and quantity of urea solution and additive. This dynamic adjustment capability enables preparation of small or large quantities as needed while managing complexity through standardized control mechanisms that can be operated simply by the end user.
