E-liquid Bottle Control Switch for Child-Safe Refilling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing e-liquid bottles and electronic cigarettes pose a risk of accidental ingestion by children due to easy-open designs, allowing access to e-liquid.
Innovation Solution
An e-liquid bottle with a control switch that seals and unseals a liquid outlet, featuring a button switch, liquid stopper, and restoring members to ensure safe e-liquid injection into an electronic cigarette, preventing unintended e-liquid flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the mouthpiece structure is made easy to remove for convenient e-liquid refilling, then the ease of operation is improved, but children can easily open it and accidentally ingest e-liquid, worsening safety
Solution Approach 1:
The mouthpiece incorporates a dynamic control switch that transitions between locked and unlocked states. The control switch includes a button that, when pressed, actuates a liquid stopper to open the liquid outlet for refilling. When released, a restoring member returns the button to its original position and the liquid stopper seals the outlet, dynamically adapting the system's accessibility based on user intent
Solution Approach 2:
The control switch mechanism changes the physical state of the liquid outlet from sealed to open through controlled parameter changes. The liquid stopper moves between blocking and non-blocking positions, controlled by the button switch mechanism. This parameter change (open/closed state) is triggered only by deliberate pressing action, preventing accidental opening while enabling convenient refilling when intentionally activated
2Ease of operation
If the liquid outlet remains open for easy e-liquid injection, then the ease of operation is improved, but e-liquid may leak or be accessed unintentionally, worsening reliability
Solution Approach 1:
The liquid outlet is preliminarily sealed by the liquid stopper before any refilling operation. The control switch mechanism is pre-configured with the liquid stopper in the closed position. When refilling is needed, the user first presses the button to activate the opening mechanism, ensuring the outlet is intentionally opened before e-liquid injection begins, preventing premature leakage
Solution Approach 2:
The restoring member provides continuous feedback to the button switch, automatically returning it to the closed position after pressing. This feedback mechanism ensures the liquid outlet closes automatically after refilling, maintaining reliability by preventing unintended e-liquid flow. The system self-regulates the open/closed state based on user interaction
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 prevents accidental e-liquid exposure by ensuring the liquid outlet is closed when not in use, enhancing safety and security for children.
Implementation Method 1
the first restoring member provides a force such that the button switch restores to its original state and the liquid stopper seals the liquid outlet
Implementation Method 2
the liquid stopper is located on an inner side of the cover and is connected to the button switch and seals an inner end of the liquid outlet
