Hand Torch Regulator Assembly for One-Handed Flame Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing torch systems for one-handed use lack efficient control mechanisms for adjusting flame size and ignition, requiring two-handed operation for flame adjustment and ignition, which limits usability and precision.
Innovation Solution
A torch system with a body having angled portions for comfortable grip, a control knob for adjusting fuel flow, and a trigger for one-handed ignition, featuring a regulator with a valve assembly and ramp assembly that allows for flame size adjustment without extinguishing the flame, enabling one-handed operation and precise flame control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If existing torch systems are used for one-handed operation, then portability and ease of use are improved, but flame adjustment and ignition require two-handed operation reducing precision and usability
Solution Approach 1:
The patent combines the ignition trigger and flame adjustment control into a single integrated control mechanism on the torch handle. This allows both ignition and flame size adjustment to be performed with one hand, eliminating the need for two-handed operation while maintaining precise control over the flame.
Solution Approach 2:
The control mechanism is designed to perform multiple functions through a single interface. The same control element that initiates ignition also enables continuous flame adjustment, making the device universally controllable with one hand for all operational requirements.
2Measurement precision
If a control knob is added for flame adjustment, then flame size control precision is improved, but the device becomes more complex requiring additional components
Solution Approach 1:
The control knob is integrated into the existing torch structure, combining flame adjustment functionality with the handle assembly. This merging approach provides precise flame size control through a single rotational mechanism without adding separate complex subsystems.
3Productivity
If the regulator allows flame adjustment without extinguishing, then operational continuity is improved, but the valve assembly becomes more complex
Solution Approach 1:
The valve assembly is designed with dynamic control capability, allowing continuous adjustment of fuel flow during operation. The ramp assembly enables the valve to transition smoothly between fully closed and fully open positions, permitting flame size adjustment without extinguishing while maintaining operational continuity.
Solution Approach 2:
The ramp assembly acts as an intermediary mechanism between the control knob and the valve assembly. It translates rotational motion into linear valve movement, enabling smooth, progressive opening of the valve to adjust flame size without abrupt changes or flame extinction.
