Child-Proof Package Wall With Sliding Selector Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing child-proof packages have complex structures and locking systems that can be easily circumvented, failing to provide a suitable level of safety and prevent children younger than 5 from opening the package.
Innovation Solution
A wall made of sheet material with a flexible, compact, and strong structure, featuring a selector mechanism that moves between operative positions to control access through the package, ensuring it can be easily opened by adults while remaining secure from children.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a locking system is implemented to prevent children from opening the package, then safety is improved, but the structure becomes complex and the locking system can be easily circumvented
Solution Approach 1:
The wall is divided into an outer panel and an inner panel that can move relative to each other. The selector element is segmented into a body and a selective portion that can be positioned in different locations. This segmentation allows the wall to provide child-proof protection while maintaining simplicity in the overall structure.
Solution Approach 2:
The wall transitions from a static structure to a dynamic one where the inner panel can move relative to the outer panel, and the selector element can be repositioned. This dynamic capability enables the wall to adapt to different user needs while maintaining child-safe design.
2Reliability
If a locking system is implemented to prevent children from opening the package, then safety is improved, but the locking system can be easily circumvented by children
Solution Approach 1:
The selector element has a specific local quality with a gripping portion that is accessible from the exterior but cannot be manipulated by children. The selective portion can be positioned in different locations to control access, providing localized functionality that prevents child circumvention while allowing adult use.
Solution Approach 2:
The selector element acts as an intermediary between the user and the wall's locking mechanism. It provides a controlled interface that adults can use to open the package while preventing children from directly interacting with or circumventing the locking system.
3Strength
If the wall structure is made compact and strong, then structural integrity is improved, but flexibility for use is reduced
Solution Approach 1:
The wall is segmented into an outer panel and an inner panel that can move relative to each other. This segmentation provides structural integrity when closed while allowing flexibility for use when the panels are separated, resolving the contradiction between strength and operational flexibility.
Solution Approach 2:
The wall structure dynamically transitions between a compact, strong closed state and a flexible open state. The ability of the inner panel to move relative to the outer panel provides both structural integrity during normal use and flexibility when opening or closing the package.

AI summary
A wall (60) made of sheet material including an outer panel (61) having a through opening (61a), an inner panel (62) engaged with the outer panel (61) and a through opening (62a). The wall includes a selector (90) engaged in interposition between the outer panel and the inner panel. The selector includes a through opening (91) and is moveable relative to the outer and inner panels between: a first operative position wherein the through opening of the selector faces the through openings of the outer and inner panels to define, essentially with the latter through openings, a single passage passing through the wall; a second operative position wherein the through opening of the selector is offset with respect to the through openings of the outer and inner panels to prevent the communication between the through openings of the outer and inner panels.
