Locking Inner-Outer Box Container for Child-Resistant Opening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing containers for storing fragile or medication goods lack reliable protection against unintentional opening, particularly by children, as existing locking mechanisms can be easily disengaged.
Innovation Solution
A container design featuring movable inner and outer boxes with locking tabs that require a specific sequence of active and passive pressure fields to open, including tactile elements for ease of use, and reinforcing tabs for stability, made from materials like cardboard or corrugated board.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If locking tabs are used to secure the inner box to the outer box, then the container is protected against unintentional opening, but the locking mechanism can be easily disengaged by simple action
Solution Approach 1:
The pressure-sensitive field is divided into multiple independent pressure-sensitive elements arranged in a code pattern. Each element corresponds to a specific digit or symbol, and only the correct sequence of pressed elements will release the locking tabs. This segmentation transforms a single vulnerable locking point into multiple interdependent locking points that must be activated in a specific sequence.
Solution Approach 2:
A pressure-sensitive field acts as an intermediary between the user and the locking tabs. When the correct code is entered by pressing the appropriate elements, the field activates a release mechanism that allows the inner box to be pulled out. This intermediary layer prevents direct access to the locking tabs while maintaining controlled accessibility.
2Reliability
If multiple locking positions are provided for the locking tabs, then security against unintentional opening is improved, but the device complexity increases
Solution Approach 1:
Multiple locking positions are merged into a single integrated pressure-sensitive field that controls all locking points simultaneously. The field contains multiple pressure-sensitive elements that, when pressed in the correct sequence, collectively activate the release mechanism for all locking tabs. This merging reduces mechanical complexity while maintaining multiple security positions.
Solution Approach 2:
The pressure-sensitive field automatically manages the locking and unlocking sequence without requiring manual intervention at each locking point. When the correct code is entered, the field self-activates the release mechanism, and the inner box can be removed by simple pulling motion. This self-service approach reduces the complexity of manual locking operations.
3Reliability
If a code-based opening mechanism is implemented, then protection against unintentional opening is enhanced, but the ease of operation in confined spaces or poor lighting is reduced
Solution Approach 1:
The pressure-sensitive elements are arranged to form visible numbers or symbols that constitute the opening code. These visual indicators guide users to press the correct elements in the correct sequence. The visual feedback mechanism allows users to identify and press the required elements without confusion, even in confined spaces or poor lighting conditions.
Solution Approach 2:
The pressure-sensitive field is designed with a curved or contoured surface that accommodates the palm and fingers of the user. This ergonomic design allows easy access and pressing of the code elements even when the container is held in confined spaces. The curved surface provides natural finger placement and reduces the effort required to press the elements.
