| <color #ed1c24>Describe and add the load and stress analysis of the structure (3D model) using the materials chosen for the product.</color> | Introduction |
| | |
| | To evaluate the structural performance of the cocoon design, a static simulation was performed in SOLIDWORKS, Figure {{ref>fig:stress}}. The cocoon was modeled using copper as the selected material. The analysis focused on the stress distribution and displacement behavior under the applied loads. The goal was to determine whether the structure is strong and rigid enough to withstand external forces without failure or excessive deformation. |

| | Conclusion |
| | |
| | The simulation results show that the copper cocoon structure performs safely under the applied load conditions. The maximum stress remains far below the material yield strength, while the displacement is extremely small. This indicates that the design is highly rigid and experiences minimal deformation, confirming that the structure is mechanically stable and suitable for its intended use. |

| To achieve this, in addition to cardboard packaging, we want to use a single, effective type of cushioning material that can be used in all product packaging and is also reusable and biodegradable. | To achieve this, in addition to cardboard packaging, we want to use a single, effective type of cushioning material that can be used in all product packaging and is also reusable and biodegradable. |

| Since our product is intended for children, our packaging will include cushioning material made from particles manufactured from cornstarch. These particles are an environmentally friendly and biodegradable alternative. Furthermore, they can later be used as craft material for children in the waiting room: with a little water, these particles stick together, allowing children to express their creativity and build structures and figures. | Since our product is intended for children, our packaging will include cushioning material made from particles manufactured from cornstarch.

| Our final choice of position is to transport the cocoon panels vertically, in order to avoid overlapping the panels and risking them colliding with each other in the event of a vertical fall. The Figure {{ref>fig:packaging_drafts}} shows the main box containing the system hardware box and the panels. The drawing on the right of the figure shows the assembly of the cardboard insert. | Our final choice of position is to transport the cocoon panels vertically, in order to avoid overlapping the panels and risking them colliding with each other in the event of a vertical fall.

| | __Main box__: |
| | |
| | The Figure {{ref>fig:mainbox_detailed_drawings}} shows the detailed and simplified design of the main box, viewed from above. It also shows the panel layout and the necessary box dimensions. |
| | The Figure {{ref>fig:mainbox_template}} shows the folding box template for the main box, with the dimensions added on it. This folding cardboard is based on the FEFCO 0201 standard [(Pack2025)], this heavy duty design uses extended flaps and strong side panels to improve stacking performance and impact resistance. |

| | __Hardware system box__: |
| | |
| | The Figure {{ref>fig:template_hardware}} shows the folding box template for the hardware system, with the dimensions and the logo added on it. This folding cardboard is based on the FEFCO 0427 standard [(Pack2025)], featuring a hinged lid that extends from the rear panel and folds over the front for closure. Designed without glue, the structure relies on interlocking tabs to secure the base instead of adhesive. Unlike conventional tuck-end boxes, the assembly method of the bottom is what makes it distinctive: the side panels are folded inward first, followed by the longer bottom flaps that lock into place over them. When assembled in the correct order, the box snaps together quickly and efficiently. |
