 Once the micro-break capsule was chosen as our final concept, we moved into a Design Thinking phase to explore its phisical form. To do this, we developed five quick sketches, each representing a different approach to how the capsule could look and function. These initial ideas, shown in Figure {{ref>fig:whatsapp_image_2026-03-25_at_17.30.52}}, allowed us to visualize various layouts and user experiences. Once the micro-break capsule was chosen as our final concept, we moved into a Design Thinking phase to explore its phisical form.

 The final concept developed for this project is an egg-shaped capsule designed to integrate seamlessly into modern corporative environments, such as large halls or corridors. Our goal was to create a private sanctuary for "micro-breaks" during long working hours, a space where employees can scape the pressure of the office to perform a "power nap", meditate, strech or even release tension in total privacy. The final concept developed for this project is an egg-shaped capsule designed to integrate seamlessly into modern corporative environments, such as large halls or corridors.

 The structure is dimensioned to be inclusive, providing enough space for a person to of average height to stand, lie down, or practice yoga confortably. A core principle of design is total isolation. The capsule is engineered to be both visually and acoustically opaque, ensuring that nothing can be seen or heard from the outside, and vice versa. This crates a true "break from the world" for the user. The structure is dimensioned to be inclusive, providing enough space for a person to of average height to stand, lie down, or practice yoga confortably.

 Functionality is also integrated into the exterior through a smart lighting system that iluminates when the capsule is occupied, signaling to others that the space is in use. Furthermore, Bloem is designed to be part of a larger digital ecosystem; it will be liked to a user interface for reservations and can provide helpful "newsletters" or guidance on mental healh and physical well-being. This ensures the capsule is not just a physical space but a proactive tool for workplace health. Functionality is also integrated into the exterior through a smart lighting system that iluminates when the capsule is occupied, signaling to others that the space is in use.

-The skeletal framework of Bloem draws deep inspiration from traditional Japanese joinery, a caftsmanship philosophy that prioritizes the assembly of wooden structures without the use of nails, screws, or industrial adhesives. By relying on interlocking joints, the structure benefits from a superior level of durability and flexibility. Unlike rigid mechanical fasteners that can weaken wood over time, these traditional techniques allow the material to expand and contract naturally, ensuring a long-lasting structural integrity. As seen in figure {{ref>fig:structural_drawings}} the structural drawings, the capsule is built around a series of vertical wooden ribs that converge at a central ring. This "puzzle like" assembly that is both an engineering feat and a warm, organic alternative to industrial frames.+The skeletal framework of Bloem draws deep inspiration from traditional Japanese joinery, a craftsmanship philosophy that prioritizes the assembly of wooden structures without the use of nails, screws, or industrial adhesives.

 This structural choice is also fundamental commitment to sustainability and circular design. By eliminating metal fasteners and chemical adhesives, the capsule becomes a mono-material system that is significantly easier to disassemble and recycle at the end of its life cycle. This design ensures that each wooden component can be individually repaired or repurposed without damaging the rest of the frame, drastically reducing the project's carbon footprint. Ultimatelly, by merging ancestral assembly techniques with modern professional needs, the structure of Bloem stands as a durable, low-impact solution that respects both natural resources and high-quality craftmanship. This structural choice is also fundamental commitment to sustainability and circular design.

-The structural drawings of Bloem illustrate a highly engineered system designed to balance formal elegance with technical performance. The assembly is built around a primary wooden skeleton, as detailed in Figure {{ref>fig:structural_drawings}}, wich utilizes a central compression ring to secure the vertical ribs. This radial configuration allows for a self-supporting dome structure that maximizes internal volume while maintaining a compact footprint within the office environment. By relying on traditional joinery as shown in the components of figure {{ref>fig:structural_drawings}}, the frame remains flexible yet stable without the need for mechanical fasteners. +The structural drawings of Bloem illustrate a highly engineered system designed to balance formal elegance with technical performance.

-The capsule uses a 12V RGB LED strip with four connections: a 12V supply line and three control lines for red, green, and blue. The color and brightness are controlled using pulse-width modulation (PWM). Each control signal is generated by a digital output pin on the ESP32 and passes through a resistor and a logic-level N-channel MOSFET. This setup allows the low-voltage ESP32 to safely control the higher voltage and current required by the LED strip. +The capsule uses a 12 V RGB LED strip with four connections: a 12 V supply line and three control lines for red, green, and blue.

 +The power budget analysis shows that the system has an estimated total power consumption of approximately 45 W, where the RGB LED strip constitutes the primary load. In comparison, the ESP32 and connected sensors contribute only a minor portion of the overall consumption, while losses in the voltage regulation stage are relatively small but included in the calculation.
 +Based on this analysis, the system requires a 12 V power supply capable of delivering at least 3.8 A. To ensure stable operation under varying load conditions, a safety margin should be applied. Therefore, a power supply in the range of 5–6 A (60–72 W) is recommended.
 +Overall, the power budget confirms that the system design is r well-justified in terms of power requirements.
