Gas Tank Neck Mount with Adjustable Thread Engagement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gas tank designs require high torque for removal of the neck mount, making it difficult to detach the tank from the apparatus.
Innovation Solution
A gas tank design featuring a neck mount and mount plate with adjustable thread engagement, allowing easy detachment by deviating the thread grooves from an integral multiple of the pitch, and a second neck with a slide collar and cover plate for supporting the tank body while allowing expansion and contraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the first and second attachments are tightened in close contact with each other to fix the neck mount, then the neck mount is securely fixed to the tank body, but a large torque is required when removing them
Solution Approach 1:
The attachment structure is divided into multiple attachments (first attachment, second attachment, third attachment) that can be independently adjusted. This segmentation allows each attachment to be positioned at different angular orientations, enabling secure fixing during operation while allowing easy removal by simply loosening the fastening elements without requiring large torque to overcome fully engaged threads.
Solution Approach 2:
The attachment system transitions from a static fully-tightened state to a dynamic adjustable state. The attachments can be rotated to different angular positions and secured at any orientation, providing flexibility in both installation and removal. This dynamic positioning capability eliminates the need for large removal torque while maintaining secure fixing during use.
2Reliability
If multiple attachments are used to secure the neck mount, then the fixing reliability is improved, but the device complexity increases
Solution Approach 1:
Each attachment is designed with universal functionality to perform multiple roles: securing the neck mount to the tank body, allowing angular adjustment, and enabling easy removal. The attachments use standardized fastening elements and thread engagements that can be independently adjusted, providing reliable fixing without requiring complex specialized mechanisms for each component.
Solution Approach 2:
The attachment structure merges the functions of securing, positioning, and adjusting into a single integrated assembly. The first, second, and third attachments work together as a coordinated system where each component contributes to both the reliability of fixing and the simplicity of the overall structure, avoiding the need for separate complex mechanisms for each function.

AI summary
The gas tank disclosed herein includes a tank body, a first neck, a neck mount, a mount plate, and a plate bolt. The first neck extends from one end of the tank body along its axis and is provided with external threads on its outer periphery. The neck mount is a component for fixing the tank body to the apparatus, and has a first female screw hole that is screwed into the male screw of the first neck. The mount plate has a second female screw hole screwed into the male screw and faces the neck mount. The plate bolt presses the mount plate against the neck mount along the axis.
