Lockable Sliding Tray for Child-Resistant Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current child-resistant containers do not effectively prevent access to articles, especially when secondary containers are opened, allowing children to access dangerous quantities of medications and other consumables, and there is a need for a cost-effective, reusable solution with a slidable, compartmentalized tray that requires coordinated motions to unlock.
Innovation Solution
A lockable package with a sliding compartmentalized tray that includes a locking mechanism and releasing mechanism, where the sliding element is locked within a sleeve using locking posts and apertures, requiring coordinated motions to unlock, and is designed to be inexpensive to manufacture and reusable.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a typical paperboard box holding primary containers is opened, then all articles are immediately available, but children who can open such containers may have access to dangerous quantities of articles
Solution Approach 1:
The package is divided into multiple compartments within a sliding tray, allowing articles to be segmented and stored separately. The tray itself is divided into multiple compartments that can hold different primary containers, creating a segmented structure that requires sequential access rather than immediate access to all articles.
Solution Approach 2:
The package incorporates a dynamic sliding tray mechanism that moves along guide rails within the package body. The tray transitions between locked and unlocked positions, and between retracted and extended positions, requiring coordinated motions to access articles. This dynamic mechanism prevents simple opening while maintaining child-resistance.
2Object-affected harmful factors
If a locking mechanism requiring coordinated alignment and tipping is used, then access is inhibited, but the mechanism complexity increases
Solution Approach 1:
The locking mechanism merges multiple functions into a single integrated system. The tab engages with both the locking posts (providing lock/unlock function) and the guide rails (providing sliding guidance). The release button combines the unlocking action with the tray release mechanism, reducing overall complexity while maintaining child-resistance.
Solution Approach 2:
The locking mechanism is designed to be self-latching through the engagement of the tab with locking posts. Once the tray is pushed to the locked position, the tab automatically engages with the posts without requiring additional locking actions. The mechanism serves itself by using the sliding motion to both position and secure the tray.
3Object-affected harmful factors
If a slidable compartmentalized tray with child-resistant features is created, then effective child-resistant storage is achieved, but manufacturing cost may increase
Solution Approach 1:
The sliding tray serves multiple functions: it provides the child-resistant locking mechanism, it creates compartmentalized storage, it enables sequential article dispensing, and it provides structural support for primary containers. This multi-functionality reduces the need for separate components, potentially lowering manufacturing costs while maintaining effectiveness.
Solution Approach 2:
The package utilizes a flexible or semi-flexible sliding tray that can be made from thin plastic or composite materials. The tray's flexibility allows it to engage with the locking posts and guide rails while maintaining structural integrity. Using thin materials reduces material costs and simplifies manufacturing processes.

AI summary
An exemplary lockable package holds a sliding element within a lockable sleeve. The sleeve comprises a base and a top. The base includes a release button defined by a release surround and a hinge that connects the release button to the base. The release button also includes a free end. Pushing inwardly on the release button urges the free end inwardly to disengage a locked sliding element. The sliding element comprises a sliding base, a sliding top, and an article cover that spans the primary containers. For example, the primary containers are pouches that hold consumable articles, such as vitamins, or personal care articles, such as contact lenses.
