Gas Combustor Safety Switch with Spring-Locked Swing Arm
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional gas combustors lack effective safety mechanisms to prevent accidental ignition by children, as the design of ignition switches is too easy to operate, leading to potential fire hazards.
Innovation Solution
A safety switch with dual functions of manual unlocking and automatic locking is integrated into the gas combustor, featuring a locking member, swing arm, and spring mechanisms that prevent accidental activation by children, allowing for secure operation and easy unlocking by adults.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a safety switch with manual unlocking mechanism is added to the gas combustor, then safety against child operation is improved, but device complexity increases
Solution Approach 1:
The safety switch integrates multiple components (locking member, swing arm, longitudinal spring, transversal spring, locking hook, latching hook) into a unified mechanism that combines manual unlocking capability with automatic locking function, resolving the contradiction by merging safety functions into a single integrated device rather than separate components
Solution Approach 2:
The safety switch employs spring mechanisms (longitudinal spring and transversal spring) that automatically reset the locking mechanism after use, and the swing arm automatically returns to the locked position after being actuated, eliminating the need for additional power sources or complex control systems while maintaining safety
2Reliability
If a locked status mechanism is implemented, then prevention of accidental ignition is improved, but ease of operation deteriorates
Solution Approach 1:
The safety switch is pre-configured with the locking member in a locked position by default, and the spring mechanisms are pre-loaded to automatically reset the lock after actuation, allowing adults to easily operate it when needed while preventing child operation
Solution Approach 2:
The swing arm provides dynamic movement between locked and unlocked positions, and the spring mechanisms provide dynamic resetting action, making the device adaptable to both safety requirements and legitimate user needs
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 safety switch enhances operational safety and durability by making accidental ignition more difficult for children, thereby reducing fire hazards and complying with safety regulations.
Implementation Method 1
the main body has a push piece protruded from the rear opening... when the push piece is longitudinally and downwardly pressed, the longitudinal spring is compressed... the locking member is upwardly displaced through an energy releasing effect of the longitudinal spring
Implementation Method 2
a transversal spring is disposed between an extending sheet below the swing arm and the inner wall of the gas combustor

AI summary
A safety switch for use in a gas combustor is disposed on a gas combustor having a rear opening, and a press button is arranged adjacent to the rear opening; the safety switch includes a locking member and a swing arm, the locking member has a main body sleeved with a longitudinal spring, and a locking hook protruded from a location towards a latching hook arranged above the swing arm, wherein a transversal spring is disposed between an extending sheet below the swing arm and the inner wall of the gas combustor; when the locking member is not pressed, the locking hook is abutted against the latching hook, a locking bolt protruded from a bottom end of the press button is abutted against the locking hook, so that the press button is unable to be pressed, thereby forming a locked status.
