3D Model Machine Exploration

From requirements to realization: navigating shapes, colors, and finishes

With the list of requirements provided by the company and users, along with the internal technological elements essential for its operation, our team embarked on the exploration of the machine's design. This involved experimenting with various shapes, colors, finishes, and the arrangement of elements. The team meticulously considered different design aspects to ensure a comprehensive and aesthetically pleasing outcome.

Wireframes Machine Interface

Crafting user experiences: integrating physical and digital dimensions in machine design

While one segment of the team focused on the physical design of the machine, another segment handled the creation of instructions and the digital user experience via the touchscreen interface. Initial wireframes were crafted, outlining the messages to be displayed at each stage of the process to guide the user. Subsequently, these wireframes were tested in conjunction with the pretotype to thoroughly assess the overall user experience.

User Testing- Concept Validation

Evaluating machine functionality and visual appeal

To gather user feedback and assess the proposed concept, we conducted a two-stage test involving 10 potential users.

Left arrow icon

Test A

Accordion icon
  • Objective: To gauge the user's understanding of the machine's functionality and identify its constituent parts.
  • Activity: Users will be presented with an image of the machine and asked to outline a series of actions or steps they believe are necessary for recycling their garbage correctly.

Test B

Accordion icon
  • Objective: To evaluate the aesthetic appeal of the machine and determine if it effectively communicates the desired aspects.
  • Activity: Users will be shown the three finalist designs and asked to select from a provided list of adjectives those that they believe best describe each design.

Redesign

Enhancement checklist: refining design elements

Checklist

  • Remove side lights.
  • Alter the machine's color.
  • Rearrange the screen position.
  • Round the corners of the machine.
  • Distinguish between the garbage inlet and outlet.
  • Bring the machine game to the forefront.

Usability Testing

Enhancing prototype interaction and ergonomics

For this validation, we utilized a life-size cardboard model to assess the front casing of the prototype. The objective was to analyze user interaction and adjust element positions for optimal comfort. Users were provided with various types of garbage and instructed to place them in what they deemed the correct space. Subsequently, we evaluated the screen's position, ensuring it was easily reachable and provided comfortable viewing during interactions.

Design changes implemented based on validation

  • We relocated the waste entry and return, initially positioned on the left side, to the right side.ectively communicates the desired aspects.
  • The game component of the machine was also moved closer to the user for improved accessibility.
  • Additionally, based on validation insights, we introduced a lever to initiate the game.

3D Models - Evolution

Iterative design progression: refinement for improved usability

  • Initially, we prioritized bringing the game to the forefront, allowing for more space around the containers.
  • Although we relocated the garbage inlet and outlet, maintaining the same shape proved to be still confusing.
  • In our latest design iteration, we centralized the screen and moved the garbage inlet and outlet to the right side of the machine, enhancing usability and accessibility to functions.
  • Additionally, we revamped the colors and rounded the corners to present a more appealing and approachable image of the machine.
  • To address confusion regarding the entrance and exit points, we implemented distinct shapes, drawing inspiration from vending or ticket machine systems for clearer user navigation.

Scale 1:3 Physical Prototype Process

Scale model construction: Botti's prototype overview

Botti's prototype was created at a 1:3 scale primarily using laser-cut MDF boards. These boards were utilized for external components such as the casing, the game interface, and the containers. Other elements were 3D printed based on the models. Following the fabrication of all parts, assemblies were constructed using a combination of glue, hinges, and screws. For the external design, 3D printing facilitated the creation of the curved surface where the cell phone would be inserted to display the application. Additionally, an acrylic sheet was employed to simulate the glass panel, which would showcase the game dynamics.

Programming and Training

Programming the garbage detection and sorting process

  • To effectively train the computer for product detection, photographs of the three materials were taken from various angles and perspectives.
  • A webcam integrated into the Raspberry Pi is utilized to identify the type of garbage placed on the main platform. This information triggers a message to the Arduino, instructing it to execute the corresponding action for each material.
  • In the event that the garbage is deemed unacceptable, the first servomotor controlling the platform activates, prompting the garbage's return through the lower door.
  • If the garbage is identified as a can or Tetra Pak, the platform's servomotor allows the garbage to pass onto the conveyor belt, driven by a DC motor for transfer. During this process, a second servomotor engages, pushing the garbage towards its designated container, where it is subsequently crushed by a shaft driven by another DC motor.
  • For glass materials, the aforementioned process is repeated, with the exception that no servomotor is activated for pushing. The garbage is solely transported by the belt until it reaches the end wall, where it then slides into its designated container.
