Automatically locking, releasable, safety knob assembly systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing safety knob assemblies for stoves either rely on cumbersome manual locking mechanisms or complex electronic locking systems, neither of which provides a reliable and convenient solution for preventing accidental stove activation.
Innovation Solution
An automatically locking, releasable safety knob assembly that incorporates a slidable button and a resiliently biased automatic locking arm, which engages and disengages from a locking notch to transition between locked and unlocked configurations, allowing the knob to freely rotate when unlocked, thereby preventing unintentional stove activation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual locking mechanisms are used, then the safety knob provides a certain level of safety, but it requires additional components and user manipulation making it cumbersome and inconvenient
Solution Approach 1:
The locking mechanism automatically engages and disengages without requiring user manipulation. The spring-loaded locking arm self-activates when the knob is rotated to the locked position, and the release button provides a simple single-action operation to unlock, eliminating the need for complex manual manipulation of multiple components
Solution Approach 2:
The invention removes unnecessary components from traditional manual locking mechanisms. By using a spring-loaded automatic locking arm that engages with a locking notch, the design eliminates the need for separate pins, levers, or multiple buttons, simplifying the overall structure while maintaining safety functionality
2Extent of automation
If complex electronic locking mechanisms are used, then automatic locking is achieved, but the device becomes overly complicated, expensive to manufacture, and prone to mechanical failures or malfunctions
Solution Approach 1:
The invention replaces complex electronic locking mechanisms with a simple mechanical system. A spring-loaded locking arm with a locking notch provides automatic locking through pure mechanical means, eliminating electronics, sensors, and control circuits while achieving reliable automatic locking functionality
Solution Approach 2:
The mechanical locking arm automatically engages with the locking notch when the knob is rotated to the locked position, and automatically disengages when the release button is pressed. This self-activating mechanical system requires no electronic control, power source, or complex programming, reducing complexity while maintaining automation
3Reliability
If traditional locking mechanisms are used, then the knob is secured, but the user cannot easily access the stove when quick and easy access is required
Solution Approach 1:
The release button provides a quick single-action operation that immediately disengages the locking arm from the locking notch, allowing rapid access to the stove when needed. The automatic locking engages seamlessly when the knob is rotated, requiring no additional time for manual locking operations
Solution Approach 2:
The locking mechanism is automatically engaged when the knob is rotated to the locked position, so the safety lock is already in place before the user needs to use the stove. This eliminates the need for separate locking actions and reduces access time when the stove needs to be quickly activated
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 solution effectively reduces the risk of accidental stove activation by providing a convenient and reliable mechanism that automatically locks the knob in the 'off' position, preventing unintentional movement and reducing the risk of fires and gas leaks.

AI summary
The present technology relates to an automatically locking, releasable, safety knob assembly for a stove. The assembly includes a base with a locking notch. An adapter mates with the stove's valve stem and has a head, a tubular middle section, and an adapter base with a central aperture for receiving the valve stem. The knob includes a housing with a housing disk covering the base, an arm movement channel aligned with the locking notch in the locked configuration, and a central aperture for receiving the adapter head. The assembly further includes a sub-assembly with a slidable button allowing free rotation of the knob in the unlocked configuration, an automatic locking arm biased with the slidable button, and engagement with the button causing the arm to disengage from the locking notch and move in the arm movement channel, enabling the knob to freely rotate and rotate the valve stem.
