Vaping Device Child-Proofing Mechanism with Spring-Loaded Tabs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vaping devices lack a method to prevent disposable liquid pods from being removed and ingested by infants or children, posing a risk of serious injury or death.
Innovation Solution
A compact vaping device with a child-proofing mechanism featuring a rotatable lid with a hidden revolute joint and spring-loaded plunger, requiring significant force to open, and spring-loaded tabs that secure the pod, making it difficult for children to access and remove the pod.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the pod is securely retained inside the casing using spring loaded tabs and retention forces, then the child safety is improved, but the ease of operation deteriorates
Solution Approach 1:
The push-hole feature is pre-configured in the casing to guide the user's finger for pod removal. This preliminary design element ensures that while the pod is securely retained during normal use, the removal action can be easily performed by an adult by simply pushing through the pre-positioned hole, thus resolving the contradiction between secure retention and ease of operation.
2Reliability
If the rotatable lid requires significant force to open via hidden revolute joint and spring loaded plunger, then the child safety is improved, but the device complexity increases
Solution Approach 1:
The spring-loaded plunger mechanism is extracted as a separate functional component within the lid assembly, allowing it to be independently optimized for child safety while maintaining the overall simplicity of the device. The hidden revolute joint is also designed as a discrete mechanism that provides the required retention force without adding excessive complexity to the overall structure.
3Productivity
If the pod contains toxic liquid substance, then the vaping function is achieved, but the harmful factors increase
Solution Approach 1:
The child-proofing mechanism with spring-loaded tabs, retention forces, and push-hole design implements preliminary anti-action by preventing unauthorized access to the toxic liquid substance before ingestion can occur. The mechanism is designed to withstand children's attempts to access the pod while allowing intentional access by adults, thus neutralizing the harmful potential of the toxic substance.
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 device effectively prevents accidental ingestion by children due to the combination of high retention force, dexterity requirements, and orientation-dependent pod removal, ensuring the pod can only be removed with deliberate adult action.
Implementation Method 1
the pod is securely held inside the front portion of the casing via a pair of spring loaded tabs frictionally engaged with bulged pads on the outer surface of the pod
Implementation Method 2
a spring loaded plunger on the rotatable lid is provided, wherein the spring loaded plunger is configured to seat inside a cavity positioned on the front portion of the casing
Implementation Method 3
the pod contains a substance configured to be heated via the heating coil turning the substance into a vapor as it passes through the mouthpiece

AI summary
A compact vaping device with a child proofing mechanism is provided. The vaping device includes a mouthpiece, battery, vaping liquid pod cartridge, and heating coil. During operation, a user takes a drag on the mouthpiece, the battery heats up the coil which turns the liquid into vapor which may be inhaled by the user. The child proofing mechanism provides solutions preventing the tamper and unauthorized use of the device.
