Tamper-Indicating Dispenser with Child-Proof Lock Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dispensers for tablets or powders lack effective mechanisms to ensure the container is filled with original products and are accessible only to adults, while preventing children from opening or accessing the contents.
Innovation Solution
The dispenser incorporates a tamper-indicating device connected to the cap and stator, a child-proof lock with elastically deformable materials and hooks, and a design that requires simultaneous pressure and turning to open, combined with a receptacle for a drying agent as a safety measure, to prevent unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the container is made easily accessible, then ease of operation is improved, but children can access the contents and product safety deteriorates
Solution Approach 1:
The child-proof lock changes the operational parameters by requiring simultaneous pressing and turning actions, transforming a simple rotational opening into a coordinated multi-step operation that children cannot perform but adults can
Solution Approach 2:
The lock mechanism uses elastic deformation of the rotor material dynamically - the rotor deforms elastically when pressure is applied and returns to its original shape when pressure is released, enabling the press-and-turn opening mechanism
2Object-affected harmful factors
If the container is sealed securely, then product safety is improved, but ease of operation deteriorates
Solution Approach 1:
The elastic rotor provides dynamic response to user input - it deforms under pressure and automatically returns to its original position, creating a secure seal that can be opened through coordinated pressing and turning actions
Solution Approach 2:
The opening mechanism merges two actions (pressing and turning) into a single operational sequence, where both actions must be performed together to overcome the child-proof lock and open the container
3Ease of operation
If the container is opened without detection, then ease of operation is improved, but reliability deteriorates
Solution Approach 1:
The tamper-indicating device performs preliminary detection - it is pre-configured to detect and record any unauthorized opening attempts or tampering actions, providing immediate visibility of container integrity status
Solution Approach 2:
The tamper-indicating device uses color changes or visual indicators to communicate the integrity status of the container, allowing users to immediately see if the container has been tampered with or opened
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 ensures the container is not opened without notice, prevents accidental or child access, and guarantees the original product is used by ensuring the cap is removed only once, thus maintaining product integrity and safety.
Implementation Method 1
the rotor must thus be deformed elastically to form an oval
Implementation Method 2
cooperating with a resilient arm arranged on the rotor in such a way that after moving the arm past the protrusion a turning-back is blocked

AI summary
Dispenser for dosing tablets or powders includes a container configured to hold the tablets or the powders. A dosing device is mounted to the container and being configured to allow the tablets or the powders to be dosed via an outlet. The dosing device includes a stator having an axis and a rotor that is connected to the stator and that can rotate about the axis of the stator. The rotor has a passage opening and a bottom portion that covers an upper portion of the stator. A cap is configured to at least cover the rotor. A first tamper-indicating device connects the cap to the stator. A second tamper-indicating device connects the stator to the container. A child-proof lock is utilized.
