Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current child-resistant packaging containers often fail to securely prevent access by children while being easily openable by adults, lacking effective mechanisms to ensure safety standards for age-sensitive contents.
Innovation Solution
A child-resistant packaging container design featuring a base section with spaced inner and outer wall segments, a deformable laterally extending flange, and a cover section with inwardly protruding sections and apertures, allowing secure closure and easy adult-opening through a specific mechanism involving apertures and projections, aligned with child safety standards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a simple closure mechanism is used, then ease of operation is improved, but child safety is worsened
Solution Approach 1:
The patent changes the mechanical parameters of the closure system by introducing a flange that must be deformed beyond its elastic limit to release the projection from the aperture. This requires applying sufficient force to permanently deform the flange structure, thereby preventing children from opening the container while allowing adults to do so easily.
Solution Approach 2:
The patent employs composite structural design combining the flange (deformable component) and the projection-aperture locking mechanism. The flange is designed with specific deformability characteristics that allow it to maintain engagement under normal conditions but release when sufficient force is applied, creating a composite system that satisfies both safety and ease-of-operation requirements.
2Reliability
If a secure locking mechanism is used, then child safety is improved, but ease of operation is worsened
Solution Approach 1:
The patent introduces a dynamic element - the deformable flange - that changes its mechanical state based on applied force. Under normal conditions, the flange maintains a rigid engagement with the projection in the aperture. When sufficient force is applied, the flange dynamically deforms to release the engagement, providing both security and ease of opening.
Solution Approach 2:
The flange structure serves itself by using its own deformability as the locking and release mechanism. The same flange that provides the locking function also provides the release function when sufficient force is applied, eliminating the need for separate locking and unlocking components.
3Strength
If the wall segments are closely spaced, then structural strength is improved, but ease of opening is worsened
Solution Approach 1:
The patent divides the wall structure into spaced inner and outer wall segments, creating a composite wall structure. This segmentation allows the outer wall segment to include the deformable flange while maintaining overall structural strength through the combined wall system. The spacing between segments provides the necessary space for the flange mechanism while the combined structure maintains strength.
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 design effectively secures contents from children while allowing adults to open the container easily, meeting safety standards by requiring appropriate force and alignment for opening, thus preventing accidental access by young children.
Implementation Method 1
The at least one projection is released from the aperture by depressing the deformable flange and applying inward pressure to the outer wall segment

AI summary
A child resistant packaging container having a closure and release mechanism is provided having a base section and a cover section, with the cover section adapted to cover the base section when in a closed state. The closure and release mechanism includes an inner aperture formed within an inner wall segment of the base section and an outer aperture formed within an outer wall segment of the base section, which is aligned with the inner aperture. A projection extending inwardly from a side wall portion of the cover section is also provided for engaging the outer aperture and the inner aperture of the base section. Thus, the closure and release mechanism retains the cover section over the base section and secures the packaging container in a closed position. The projection is released from the outer aperture by depressing a deformable flange and applying inward pressure to the outer wall, thereby opening the packaging container.
