Child-Safe Packaging with Concealed Gripping Edge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging for consumer goods like smoking materials and medication is not adequately child-safe, as children can inadvertently access and open them, posing a risk.
Innovation Solution
A child-safe packaging design featuring a box with a hingedly attached lid and a casing that conceals the gripping edge, requiring manipulation to access and open, made from synthetic or biopolymer materials, allowing adult-only access through compression or pushing of the casing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the packaging is made with a simple openable lid, then ease of operation is improved, but child safety deteriorates as children can easily open it
Solution Approach 1:
A casing is introduced as an intermediary element between the hand and the gripping edge of the lid. The casing initially conceals the gripping edge, preventing direct access, and must be manipulated (pushed down or compressed) by an adult to expose the gripping edge for opening the lid
Solution Approach 2:
The packaging is divided into separate functional components: the box with lid and hinge as one unit, and the casing as a separate protective element. This segmentation allows the casing to independently control access to the gripping edge without interfering with the lid opening mechanism itself
2Ease of operation
If the gripping edge is made accessible for easy opening, then ease of operation is improved, but child safety deteriorates as children can access it
Solution Approach 1:
The casing is designed to be manipulated in advance (pushed down or compressed) to expose the gripping edge before the lid can be opened. This preliminary action by an adult prepares the packaging for opening while preventing children from directly accessing the gripping edge
Solution Approach 2:
The casing acts as a mediator that controls the timing and accessibility of the gripping edge, requiring a specific adult manipulation action to transition from concealed to accessible state
3Object-affected harmful factors
If the casing is added to conceal the gripping edge, then child safety is improved, but device complexity increases
Solution Approach 1:
The casing is made from flexible plastic material that can be easily molded and manufactured. This flexibility allows the casing to be designed as a simple wraparound structure that conceals the gripping edge without requiring complex mechanical components
Solution Approach 2:
By separating the casing from the box-lid-hinge assembly, the complexity is distributed. The casing can be manufactured independently as a simple protective shell, while the box-lid-hinge maintains its original simple structure
4Ease of operation
If the lid is hingedly attached to the box, then ease of operation is improved, but manufacturing complexity increases
Solution Approach 1:
The hinge is integrated directly into the injection-molded box-lid assembly, merging the hinge function with the structural components. This eliminates the need for separate hinge components and simplifies manufacturing through a single injection-molding process

AI summary
Packaging from synthetic material or biopolymers, consisting of a box with lid, whereby the lid is hingedly attached on one side to the box and on the other side is provided with a gripping edge, with which the lid can be lifted to open the lid, whereby the gripping edge is made inaccessible by a casing located around the box, said casing having to be manipulated to make the gripping edge accessible, after which the lid can be manually lifted.
