Gas Lighter Roller-Rotation Restraining Part for Child Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional gas lighters pose a fire hazard due to their ease of ignition, which can be accidentally triggered by children, as they require minimal force to rotate the roller, leading to unintended ignition and potential accidents.
Innovation Solution
A gas lighter design incorporating a roller-rotation restraining part that extends from the cap to contact the roller, increasing the required finger grasp force for ignition by adding a rotation-restraining force, making it difficult for children to ignite the lighter.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the roller is designed to rotate easily with minimal force, then the ease of operation is improved, but the safety against child accident is worsened
Solution Approach 1:
The patent changes the rotational resistance parameter of the roller by introducing a roller-rotation restraining part that engages with the roller during rotation. This restraining part increases the rotational friction and requires greater finger grasp force to rotate the roller, thereby preventing child accident while maintaining ease of operation for adults
2Object-affected harmful factors
If a roller-rotation restraining part is added to increase rotation-restraining force, then the safety against child accident is improved, but the device complexity is worsened
Solution Approach 1:
The roller-rotation restraining part is merged with the cap structure, combining the restraining function with the existing cap component. This integration approach adds the safety function without requiring a completely separate complex mechanism, thus limiting the increase in device complexity while maintaining effectiveness against child accident
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 accidental ignition by children by requiring a larger force for ignition, thereby reducing the risk of fire hazards while still allowing adults to easily ignite the lighter.
Implementation Method 1
a roller-rotation restraining part which is caught to and brought in contact with the roller, so that a certain rotation-restraining force is added to the rotation of the roller

AI summary
The present invention relates to a gas lighter with a roller-rotation restraining part, extending toward a roller from one side of a top surface of a cap for surrounding a nozzle of the gas lighter so that the roller-rotation restraining part is caught by and brought in contact with the roller. Thus, a certain rotation-restraining force is added to the rotation of the roller by means of the roller-rotation restraining part which is caught by and brought in contact with the roller during the rotation of the roller for ignition to increase a finger grasp force required for the ignition of the gas lighter through the rotation of the roller, thereby being capable of preventing an accident, should the lighter get into the hands of a child.
