Igniter Safety Mechanism with Dual-Hand Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional igniters, such as torch burners, pose a safety risk when used by children due to ease of operation, and existing safety devices are either ineffective or compromise usability for adults.
Innovation Solution
An igniter design featuring a safety mechanism that requires both hands to operate, utilizing a movement restricting section and permitting section, where the movement restricting section is controlled by an operating section on the opposite side of the ignition operating section, making it difficult for children to activate while maintaining usability for adults.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a simple trigger mechanism is used for ignition, then ease of operation is improved, but safety is worsened due to children being able to operate it easily
Solution Approach 1:
The patent introduces a movement restricting section as an intermediary mechanism between the child user and the ignition trigger. This section includes restricting sections that physically block the trigger from moving to the ignition position, and a permitting section that must be actively engaged to allow trigger movement. The intermediary mechanism effectively filters out unintended activation by children while maintaining operational simplicity for adults.
2Object-affected harmful factors
If a complex safety device structure is used to prevent child operation, then safety is improved, but ease of operation is worsened for adult users
Solution Approach 1:
The safety device is segmented into distinct functional sections: restricting sections that block trigger movement, a permitting section that allows movement, and a movement restricting section operating section that controls the transition between restricted and permitted states. This segmentation allows each component to perform its specific function with simple geometry, avoiding the need for a complex integrated mechanism while achieving effective child protection.
3Object-affected harmful factors
If a movement restricting section with restricting sections and permitting section is introduced, then safety is improved by preventing child operation, but device complexity is worsened
Solution Approach 1:
The movement restricting section is designed as a dynamic component that can shift between positions to either restrict or permit trigger movement. The operating section allows users to dynamically change the state of the safety mechanism from restricted to permitted and back. This dynamic design enables a single component to perform multiple safety functions without requiring separate fixed restricting and permitting mechanisms, thereby reducing overall device complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design effectively prevents children from accidentally igniting the device while allowing adults to use it safely and easily by requiring coordinated two-handed operation, ensuring high safety standards are met.
Implementation Method 1
a spark discharge is then induced in the gas thus taken in, by using a piezoelectric material or the like, thereby igniting the gas

AI summary
An igniter can include a safety mechanism which is easily operated by an adult but is difficult for a child to release. In particular, an igniter can include: a nozzle section which emits a flame; a fuel introduction section; an ignition section which ignites the introduced fuel, wherein the ignition section is configured in such a manner that the fuel is ignited by movement of an ignition operating section to an ignition position; a movement restricting section having restricting sections which restrict the movement of the ignition operating section; and a permitting section which permits movement. When moving the movement restricting section, either the restricting sections or the permitting section can be disposed so as to correspond to the direction of movement of the ignition operating section.
