 +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.

-Include and explain in detail the:  +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.

 ==== Prototype ==== ==== Prototype ====
  
-Refer main changes in relation to the designed solution.+Several modifications were made when translating the final design into a physical prototype. The prototype was developed mainly to validate the shape, proportions, and accessibility concept, rather than to demonstrate the complete functionality of the final product. 
 + 
 +Compared to the designed solution, the prototype is structurally downscaled and simplified. The final product is intended to include integrated electronics, such as a projection system, speakers, sensors, lighting, and a QR-controlled application. These components were omitted from the prototype, as the immersive experience will instead be demonstrated using an external projector.

-Detail and explain any changes made in relation to the designed solution, including structural downscaling, different materials, parts, etc.+ 
 +The prototype was scaled down to approximately 65 cm in height and 60 cm in diameter. Instead of the intended materials and manufacturing methods of the final product, a lightweight structure was created using bent PVC tubes. These tubes were connected with custom connectors designed in SolidWorks and produced using 3D printing. 
 + 
 +To create the curved shell, strips of paper were cut and attached to the frame. This solution was chosen because it is lightweight, inexpensive, and suitable for quickly visualizing the overall shape. 
 + 
 +Several parts of the final design were intentionally omitted, including the electronic components, interior finishes, and control interface. The prototype therefore focuses purely on the exterior form and accessibility of the cocoon. 
 + 
 +Overall, the prototype differs significantly from the final product in terms of scale, materials, and functionality. While the final product will consist of durable materials and integrated technology, the prototype serves primarily as a proof of concept to communicate the design intent and validate the overall structure.

-//Provide here the conclusions of this chapter and make the bridge to the next chapter.//+The Healing Cocoon is an evidence-based, multisensory environment designed to alleviate pre-appointment anxiety in pediatric patients. By combining immersive projection, spatial audio, and calming scents in a wheelchair-accessible, semi-enclosed structure, the project provides a hygienic, wearable-free alternative to VR. The team successfully developed the structural design, a functional web application, and hardware integration plans within a €100 budget , prioritizing eco-efficiency and patient safety.
