Concealed Elastic Locking Packing Box
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lockable packaging for children's safety has an exposed and complex locking structure with weak elasticity, making it difficult to prevent accidental opening by children.
Innovation Solution
A packing box design featuring an outer and inner box with an elastic protruding portion that abuts against a first abutting portion to lock the boxes, allowing easy unlocking by pressing the elastic protruding portion with external force, and a concealed locking mechanism to prevent accidental opening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a locking structure is used in conventional packaging, then the packaging can be secured, but the locking position becomes exposed and the structure becomes complex
Solution Approach 1:
The locking structure is merged with the box body itself. The elastic protruding portion is formed from the box wall material, and the abutting portion is integrated into the box structure, eliminating separate locking components and simplifying the overall structure while maintaining security functionality
Solution Approach 2:
The locking mechanism is nested within the box structure. The elastic protruding portion is positioned inside the box body, and the abutting portion is recessed into the box wall, concealing the locking mechanism within the box rather than exposing it on the exterior surface
2Reliability
If a locking structure with strong elasticity is used, then the locking function is improved, but the opening position becomes more exposed
Solution Approach 1:
The locking mechanism is nested within the box structure. The elastic protruding portion is positioned inside the box body, and the abutting portion is recessed into the box wall, concealing the locking mechanism within the box rather than exposing it on the exterior surface where children could access it
Solution Approach 2:
Different regions of the box have different functional properties. The locking mechanism is localized to specific positions (protruding portion in one location, abutting portion in another), with the elastic property concentrated only where needed for locking, while other areas maintain their structural or protective functions
3Reliability
If a complex locking structure is used, then the security is improved, but the manufacturing cost increases
Solution Approach 1:
The locking structure is merged with the box body itself. The elastic protruding portion is formed from the box wall material, and the abutting portion is integrated into the box structure, eliminating separate locking components and reducing manufacturing steps, tooling requirements, and assembly operations while maintaining security functionality
Solution Approach 2:
The box structure provides its own locking function through the elastic protruding portion and abutting portion integration. The material itself performs the locking function without requiring additional components or complex assembly processes, reducing manufacturing complexity and cost
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 packing box provides a simple and effective locking mechanism that is easy to unlock with minimal force, keeping the locking position concealed to prevent children from opening it accidentally, while being environmentally friendly and cost-effective.
Implementation Method 1
an elastic protruding portion is arranged on an outer wall of the inner box; when the inner box is accommodated in the first accommodating cavity, the elastic protruding portion abuts against the first abutting portion
Implementation Method 2
when the elastic protruding portion is pressed by using an external force, the elastic protruding portion moves to the first accommodating cavity and is staggered with the first abutting portion

AI summary
A packing box includes an inner box and an outer box, where an inner wall of the outer box is provided with a first abutting portion, an outer side wall of the inner box is provided with an elastic protruding portion, and when the inner box is accommodated in a first accommodating cavity of the outer box, the elastic protruding portion abuts against the first abutting portion in a pull-out direction so that the packing box is in an locked state; when the elastic protruding portion is pressed by using an external force, the elastic protruding portion is staggered with the first abutting portion, so that the inner box and the outer box are in an unlocked state. A locking structure is formed by using the elastic protruding portion and the first abutting portion. The locked state can be released by pressing the elastic protruding portion by using a finger.
