Dual-Cap Child-Resistant Closure With Usage Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing child-resistant packages lack effective mechanisms to prevent premature opening by children while ensuring timely access by adults, and there is a need for a system to track and record usage data for improved safety and compliance.
Innovation Solution
A child-resistant package design featuring a dual-cap closure with an electronic system that requires a two-step process of downward force and rotation to unlock, accompanied by an electronic system that tracks and stores data on usage, providing indicators for timely access and compliance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a child-resistant closure mechanism is used, then safety against premature opening is improved, but ease of operation deteriorates
Solution Approach 1:
The closure is divided into an outer cap and an inner cap that function independently. The outer cap provides child-resistant protection requiring a specific two-step operation, while the inner cap contains the actual product access mechanism. This segmentation allows the outer cap to focus on safety while the inner cap handles the opening function, resolving the contradiction between safety and ease of operation.
Solution Approach 2:
The outer cap must be removed before the inner cap can be accessed. This preliminary action of removing the outer cap first creates a sequential operation that ensures child-resistant safety is maintained while ultimately allowing authorized users to access the product through the inner cap, balancing safety requirements with operational feasibility.
2Loss of information
If electronic tracking system is added, then monitoring of timely access is improved, but device complexity increases
Solution Approach 1:
The outer cap serves multiple functions: it provides child-resistant protection, acts as a handle for the two-step operation, and houses the electronic tracking system. By making the outer cap multi-functional, the electronic tracking capability is added without requiring a separate dedicated component, thus reducing the overall device complexity while still achieving usage monitoring.
Solution Approach 2:
The electronic tracking system is merged with the outer cap structure rather than being a separate component. The processor, memory, and sensor elements are integrated into the outer cap assembly, combining the mechanical closure function with electronic monitoring in a single integrated unit, thereby minimizing additional complexity.

AI summary
A package comprises a container and a closure. The container includes a body formed to include a product-receiving space, a filler neck coupled to the body, and a thread coupled to the filler neck. The closure includes an outer cap, an inner cap arranged radially inward of the outer cap, and an electronic system arranged between the outer cap and the inner cap.
