Yogi

Yogi began as a response to the way college students struggle to maintain consistent cooking habits around changing schedules, shared kitchens, limited storage, cleanup burden, ingredient waste, and planning fatigue.

The goal was not just to make another lunchbox, but to create a system that could support cooking from raw ingredients with less time pressure and fewer barriers to follow-through.

Research pointed toward a recurring gap between intention and follow-through. Students wanted to cook and meal prep, but time constraints, cleanup, ingredient waste, and decision fatigue often made eating out or choosing convenience food feel easier.

This pushed the project toward an efficient, low-effort, adaptable system that could support busy schedules and reduce the number of decisions required before eating.

Personas were used to understand how different students experience the same meal prep problem through different constraints, including diabetes management, stomach sensitivities, chronic stress, limited dorm kitchens, inconsistent motivation, and limited prep time.

Across these situations, the strongest opportunities centered on reducing friction, improving accessibility, supporting adaptability, and preventing meal prep from becoming repetitive or restrictive.

Early design directions explored three different approaches: a carb meter scanner, a modular lunchbox, and a portable cooking top. Each direction addressed prevention, treatment, or preparation from a different angle.

The modular lunchbox and portable cooking concepts became the strongest foundation because they directly addressed mobility, cleanup, portioning, cooking flexibility, and the need for a system that could work around student routines.

The refined concept became a sleek, modular lunchbox designed for college students that can cook and prepare meals on the go, paired with an app offering meal tracking, ingredient preservation tips, and personalized recipe suggestions.

The physical product handled portability, cooking, heat insulation, storage, and modularity, while the app handled ingredients, recipes, onboarding, cooking control, and feedback.

The system needed to work as both a physical product and a digital service. Storyboards and task flows mapped how a student would check ingredients, choose a recipe, prep food, load the lunchbox, cook later, and receive status updates.

The interaction model balanced visible actions, like carrying, loading, and cooking, with less visible system behavior, like ingredient tracking, Bluetooth connection, cooking status, and recipe suggestions.

Physical development moved through sketching, CAD, and mid-fidelity prototyping. The lunchbox needed to feel familiar enough to carry, but capable enough to cook, insulate, and organize food without adding another complicated object to a student’s routine.

The mid-fidelity model helped define the structure, handle, casing, control panel, removable tray, and material strategy before the final visual design was refined.

The app supported the lunchbox by helping users track ingredients, discover recipes, control cooking, and maintain meal-prep routines. Early wireframes focused on structure and task flow before moving into a more polished visual system.

The mid-fidelity screens were used to test whether users could understand the main flows before the final interface was developed.

User testing evaluated the concept as a combined physical and digital system. Participants interacted with the physical prototype and app screens to test clarity, perceived usefulness, portability, recipe discovery, ingredient tracking, and cooking setup.

Feedback showed that users liked the modular lunchbox and found the app useful for ingredient tracking and recipes, but the system needed clearer usability details, simpler navigation, and refinement around hot parts, container fit, and portability.

After testing, the physical design was refined into a softer rectangular form with a visible control panel, strap-based portability, rounded edges, insulated surfaces, and a material palette that felt more like a lunch object than a kitchen appliance.

The final form emphasized portability, cleanability, heat protection, and a familiar object language so the cooking function would feel approachable in student spaces.

The final interface used a brighter food-focused visual direction, recipe imagery, freshness tips, meal-prep streaks, profile settings, ingredient tracking, and cooking controls to make the system feel more approachable and motivating.

The app acts as the planning and feedback layer for the lunchbox, helping students move from ingredients to recipes to cooking with fewer decisions.

The final concept pairs a portable cooking lunchbox with a companion app that helps students track ingredients, receive freshness tips, find personalized recipes, and control cooking around their schedules.

Yogi demonstrates product-system thinking across research, physical product design, app design, prototyping, usability testing, and visual communication.
