Disposable Additive Capsule for Simultaneous Fuel Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for delivering gaseous fuel and additives to motor vehicle gas systems require separate operations and involve the use of pressurized cylinders, which are cumbersome, require careful handling, and can lead to incorrect additive dosing if not used properly.
Innovation Solution
A delivery unit that incorporates a disposable capsule containing additive, which is inserted into a feed duct and opened by fuel pressure, allowing simultaneous delivery of gaseous fuel and additive through a supply pipe connected to the gas system, eliminating the need for separate operations and pressurized cylinders.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pressurized cylinders are used to deliver additive, then the additive can be supplied to the gas system, but the cylinders require careful handling, temperature control, and must be stored separately, increasing operational complexity and time
Solution Approach 1:
The patent combines the additive delivery function with the existing fuel delivery infrastructure by integrating the additive capsule into the fuel tank. This merging eliminates the need for separate pressurized cylinder storage and handling, while maintaining reliable additive delivery through the shared fuel delivery system.
Solution Approach 2:
The patent employs disposable capsules containing the additive, which are inserted into the fuel tank and then discarded after use. This approach replaces the need for reusable pressurized cylinders, simplifying storage and handling requirements while ensuring reliable additive delivery.
2Adaptability or versatility
If separate operations are used for additive delivery and fuel refueling, then each operation can be performed independently, but the refueling process becomes more time-consuming and operationally complex
Solution Approach 1:
The patent merges the additive delivery operation with the fuel refueling operation by inserting the additive capsule into the fuel tank during the refueling process. This allows both operations to be performed simultaneously, eliminating the time loss associated with separate operations while maintaining operational flexibility.
Solution Approach 2:
The additive capsule is inserted into the fuel tank before the refueling operation begins. This preliminary action ensures that the additive is ready for delivery when fuel flow starts, allowing simultaneous operation and reducing overall refueling time without compromising operational flexibility.
3Reliability
If pressurized cylinders are used for additive delivery, then the additive can be supplied under pressure, but the cylinders must be stored at controlled temperatures and handled carefully, increasing storage requirements and operational difficulty
Solution Approach 1:
The patent replaces pressurized cylinders with disposable capsules that do not require pressure control or temperature maintenance. These capsules are simply inserted into the fuel tank, eliminating the ease of operation problems associated with storing and handling pressurized cylinders while maintaining reliable additive delivery.
Solution Approach 2:
The patent extracts the pressure control requirement from the additive delivery system by removing the pressurized cylinder component. The additive is delivered through the existing fuel delivery system without requiring separate pressure control mechanisms, significantly improving ease of operation while maintaining delivery reliability.
4Adaptability or versatility
If multiple separate operations are required for additive and fuel delivery, then each component can be delivered independently, but the overall process becomes more complex and time-consuming
Solution Approach 1:
The patent merges the additive delivery system with the fuel delivery system, allowing both substances to be delivered simultaneously through the same infrastructure. This integration maintains the versatility of the delivery system while significantly improving refueling efficiency by eliminating sequential operations.
