Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cardboard packages for shipping personal hygiene products are complex, difficult to open and re-close, and require excessive packaging material, often resulting in damage during handling and distribution.
Innovation Solution
A unitarily formed cardboard package with hinged lid sections and a reinforcing panel, allowing easy opening and re-closing, and minimizing the need for additional packaging materials, while providing stability to protect the product during shipping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional cardboard packages are used with protective padding and multiple components, then product protection during shipping is improved, but package complexity and amount of packaging material increase
Solution Approach 1:
The patent combines the protective packaging function directly into the cardboard package structure itself through integrated flaps and recesses, eliminating the need for separate protective padding materials. The recesses in the base wall and corresponding flaps create built-in cushioning and securement mechanisms that protect the product without requiring additional packaging components.
Solution Approach 2:
The cardboard package structure serves multiple functions simultaneously: the flaps provide both closure and protective cushioning, the recesses provide both structural support and product securement, and the overall design provides both shipping protection and reuse capability. This multi-functionality reduces package complexity by eliminating dedicated separate components for each function.
2Reliability
If conventional packages are sealed with wire or tape, then secure closure is achieved, but ease of opening and re-closing is reduced
Solution Approach 1:
The patent employs dynamic hinged flaps that can be easily opened and closed multiple times without damage. The flaps are designed to fold and unfold smoothly, providing secure closure when closed while allowing effortless opening when needed. This dynamic design replaces static wire or tape sealing with a flexible, reusable mechanical closure system.
Solution Approach 2:
The hinged flap structure is self-contained and requires no additional tools or materials for opening or closing. The user can simply fold the flaps to open or close the package, with the structure itself providing the sealing function through its geometry and friction, eliminating the need for wire, tape, or other external fastening materials.
3Reliability
If conventional packages are designed for single use, then product protection is ensured, but environmental impact and material usage increase
Solution Approach 1:
The patent designs the cardboard package to be recoverable and reusable after its initial shipping function. The durable cardboard construction and simple hinged flap closure allow the package to be opened, the product removed, and the package itself retained for subsequent reuse as storage or shipping container, thereby recovering the packaging material instead of discarding it after single use.
Solution Approach 2:
The package transitions from a single-use shipping container to a reusable storage container through its durable construction. The cardboard material and structural design maintain sufficient integrity after opening to allow the package to serve additional functions, changing its lifecycle from disposable to multi-purpose, thereby reducing overall material waste.

AI summary
A package unitarily formed from a cardboard blank includes a back wall, two hinged lid sections to open and close the package, and a first and second pairs of side walls extending from the back wall. One hinged lid section extends from one of the side walls of the first pair and the other from the other side wall of the first pair. A panel having at least one aperture for receiving the product extends from one side wall to the other side wall of the second pair and is arranged between the back wall and the hinged lid sections when the package is closed. The panel includes at least one reinforcing brace extending substantially perpendicular from the panel towards the back wall.
