| Immediately following the initial presentation, the group gathered to evaluate the proposed project tracks and reach a consensus. Our approach was rooted in an open brainstorming session where we weighed our individual strengths against the potential of each topic. It quickly became clear that the "Smartification of Objects" was the path that generated the most genuine enthusiasm among us. | Immediately following the initial presentation, the group gathered to evaluate the proposed project tracks and reach a consensus.

| | Finite Element Analysis (FEA) was carried out in SolidWorks to evaluate the bottle's mechanical behavior under two specific scenarios. First, a lateral static load of 100 N was applied to simulate a firm physical grip. The resulting maximum von Mises stress was only 0.203 MPa, showing that daily handling forces are mechanically negligible. |
| | |
| | Next, a 1.5-meter drop test was simulated. In this dynamic scenario, the maximum stress peaked at 133.7 MPa, with the impact forces heavily concentrated along the bottom edge of the bottle. To properly protect the internal electronics, two variations for the 0.8–1.0 mm aluminum body were analyzed. When using standard Aluminum the Factor of Safety (FoS) is 1.08. This prevents catastrophic structural failure but leaves a very tight margin against plastic deformation like cosmetic denting. Upgrading the main body to Aluminum (yield strength of approx. 276 MPa) increases the FoS to 2.06, providing a much safer margin. |
