Threaded Fuel Cap Holder for Secure Retention During Fueling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fuel cap holding mechanisms in vehicles are either ineffective in securely retaining the fuel cap or are difficult to use, leading to potential damage to the vehicle and spills during fueling.
Innovation Solution
A threaded fuel cap holder with a receptacle having a threaded inner surface to receive the fuel cap and mounts such as through holes and grooves for secure attachment to the vehicle's fuel panel, ensuring easy installation and intuitive use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fuel cap holding mechanism is implemented, then the fuel cap can be securely retained during fueling, but the device complexity increases
Solution Approach 1:
The fuel cap holder utilizes the existing fuel panel structure and fastening holes to secure itself, requiring no additional active components or complex mechanisms. The holder simply engages with the fuel panel's built-in features, allowing the system to serve itself without external intervention or complex control systems.
Solution Approach 2:
The fuel cap holder serves multiple functions: it provides fuel cap retention, covers sharp flanges on the fuel panel, and utilizes existing fastening holes for installation. This multi-functionality reduces the need for separate components and simplifies the overall system design.
2Ease of operation
If a threaded fuel cap holder with mounts is used, then the installation becomes secure and easy, but the manufacturing complexity increases
Solution Approach 1:
The fuel cap holder is divided into distinct functional segments: the holder body with threaded receptacle, the mount features with fastening holes, and the flange coverage elements. This segmentation allows each part to be manufactured independently using standard processes, then assembled together, simplifying both manufacturing and installation.
Solution Approach 2:
The holder is designed with pre-formed mount features including fastening holes and engagement protrusions that are created during the molding process. This preliminary formation of installation features eliminates the need for post-manufacturing drilling or complex assembly operations, making both manufacturing and installation easier.
