Gas Torch Joint Assembly for Multi-Tank Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gas torch designs lack a secure handhold and are limited to connecting with only one type of gas tank, making them inconvenient for various uses and prone to dropping.
Innovation Solution
A gas torch design featuring a torch head assembly, engagement plate, and joint assembly that allows the engagement plate to tilt outwardly for secure hand placement and rotate for adjustable angles, and includes a joint assembly that can connect to different types of gas tanks through various joint assemblies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If no holding component is provided on the gas torch, then the structure remains simple, but the user cannot hold the torch firmly and it may drop on the ground
Solution Approach 1:
The engagement plate merges multiple functions: it serves as both a structural connector between the joint assembly and torch head assembly, and as a user handhold component. The tilted engagement plate creates a compartment that naturally receives and secures the user's hand, combining safety functionality with structural support without adding separate components.
Solution Approach 2:
The engagement plate performs multiple roles simultaneously: it provides mechanical engagement for the joint assembly, creates a user handhold compartment, and serves as a safety feature to prevent dropping. This multi-functionality resolves the contradiction by improving ease of operation without proportionally increasing device complexity.
2Adaptability or versatility
If the gas torch is designed to connect to only one kind of gas tank, then the connection structure is simple, but it is not convenient to use on different occasions
Solution Approach 1:
The joint assembly is designed with universal adaptability to connect to different types of gas tanks (propane, butane, isobutane). The joint members can be rotated and adjusted to accommodate various tank configurations, allowing a single torch design to work with multiple gas tank types without requiring separate connection mechanisms for each tank type.
Solution Approach 2:
The joint members are designed to be rotatable and adjustable, providing dynamic adaptation to different gas tank types. This mobility allows the connection structure to reconfigure itself for different tank geometries and connection interfaces, achieving versatility without complex fixed mechanisms for each tank type.
3Adaptability or versatility
If the torch head is fixed in one position, then the structure is stable, but it cannot be positioned at various angles for different uses
Solution Approach 1:
The engagement plate is designed to be rotatable with respect to the connected portion of the torch head assembly, allowing the torch head to be positioned at various angles. This dynamic capability enables users to adjust the torch head orientation for different application needs while maintaining structural integrity through the engagement plate's connection mechanism.

AI summary
A gas torch includes a torch head assembly including a coupled base and a connected portion coupled to an outer periphery of the coupled base. A joint assembly, which is coupled to the coupled base and adapted for connecting to a nozzle of a bottled gas tank, includes a first joint member and a second joint member communicating with the first joint member. Two fasteners are inserted through the first and second joint members and engaged with the coupled base of the torch head. The joint assembly enables the torch head assembly to connect to different kinds of gas tanks.
