Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for supplying gaseous fuel and additive products to motor vehicles are not user-friendly, leading to increased time required for refilling operations.
Innovation Solution
A device with refillable inserting means that can be partially inserted into the fuel supply conduit to release a dose of additive product, allowing for quick and simple refilling, and are extractable when the dose is finished, facilitating efficient handling and operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If existing devices for supplying gaseous fuel and additive products are used, then the refilling operation can be performed, but the time required for refilling operations increases and ease of use deteriorates
Solution Approach 1:
The device is divided into distinct functional segments: a reusable holder (7) that remains outside the conduit and disposable inserting means (202) that are inserted into the supply conduit (6). This segmentation allows the complex refilling operation to be simplified into straightforward steps of inserting and extracting, significantly improving ease of operation while reducing refilling time.
Solution Approach 2:
The inserting means (202) are designed as disposable single-use components that are inserted into the supply conduit, deliver the additive product, and then extracted and discarded. This eliminates the need for complex cleaning and preparation procedures between uses, making the device extremely easy to operate and dramatically reducing the time required for successive refilling operations.
2Ease of operation
If the inserting means are made extractable from the supply conduit, then ease of operation improves, but device complexity increases
Solution Approach 1:
The inserting means (202) are designed to be completely extractable from the supply conduit (6) after delivering the additive product. This extraction capability simplifies the operation by eliminating the need for complex internal mechanisms to retain or reset components, while the simple insert-and-extract motion actually reduces overall device complexity compared to systems requiring in-conduit manipulation.
Solution Approach 2:
The extracting means (204) are designed to automatically engage with the inserting means (202) when the holder (7) is removed from the supply conduit (6), causing the inserting means to be pulled out automatically. This self-service extraction mechanism eliminates the need for manual manipulation or complex actuation systems, improving ease of operation while maintaining simple device architecture.
