Child Resistant Container with Integrated Audio Device and Bayonet Lock
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional childproof containers are often difficult for adults to open and lack smooth surfaces for efficient storage, while existing solutions do not effectively incorporate a musical feature to deter children from ingesting harmful substances.
Innovation Solution
A child-resistant container with a bayonet lock mechanism and an integrated audio device, featuring radially spaced slots and pins, and a compartment for a sound-emitting device, which forms a closed electrical circuit when the lid is secured, optionally including a protective screen and gasket for sealing and alert functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a childproof lock mechanism is implemented, then child safety is improved, but ease of operation for adults deteriorates
Solution Approach 1:
The lock mechanism is divided into distinct functional segments: a child-resistant bayonet lock system with radially spaced slots and pins, and a separate audio alert system. This segmentation allows the mechanical locking function to be optimized for child safety while the audio component provides additional deterrence without interfering with adult access capability
Solution Approach 2:
The audio device serves as an intermediary element that provides feedback when the container is opened. The musical notes or alert tones act as a mediator between the mechanical locking system and the user, providing an additional layer of child deterrence while not preventing adults from opening the container using the proper technique
2Reliability
If a musical device is added to the container, then child deterrence is improved, but device complexity increases
Solution Approach 1:
The container lid is designed to serve multiple functions: it provides the primary child-resistant locking mechanism through the bayonet lock system, houses the audio alert device for additional child deterrence, and maintains a compact cylindrical form factor. This multi-functionality allows the addition of the musical device without proportionally increasing overall complexity
Solution Approach 2:
The audio device is nested within the container lid structure, specifically housed in a compartment formed in the lid. This nesting approach allows the musical component to be integrated into the existing container design without requiring separate external components, thereby minimizing the increase in device complexity
3Reliability
If a bayonet lock mechanism with slots and pins is used, then child resistance is improved, but manufacturing precision requirements increase
Solution Approach 1:
The bayonet lock mechanism employs asymmetric radially spaced slots in the neck and corresponding pins in the cuff that are positioned at specific angular intervals. This asymmetric arrangement provides inherent alignment guidance during assembly, reducing the need for high-precision manufacturing while maintaining effective child-resistant locking functionality
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 container effectively prevents children from opening it while allowing adults to access the contents easily, with the musical feature providing an additional deterrent and alert functionality for secure storage.
Implementation Method 1
A sound emitting device is housed in the compartment. The pins and slots engage to form a bayonet lock mechanism for removably securing the cap to the top of the container.

AI summary
A container having a child resistant lock and an audio device has a bottom, an outer wall, and a neck extending upward from its top. The neck has one or more slots formed by a vertical channel and a slanted channel leading to a seat. The slanted channel has two opposing protuberances where it joins the seat. A lid has a cuff configured to fit over the neck. The inside wall of the cuff has one or more pins complementary to the one or more channels which together form bayonet lock mechanisms. And gasket at the inside top of the cuff seals the container when the bayonet lock mechanisms are engaged and provide an upward bias to the cuff, thereby securing it in place. The outer wall of the cuff and outer wall of the canister lie flush with each other when the bayonet lock mechanisms are engaged. The top of the lid has a removable screen covering a compartment in the lid which houses an audio device. A plurality of apertures in the plate allow sound to emit from the music box.
