Lunch Box
This project rethinks the lunchbox as a wearable food system designed for movement. While traveling with food is a daily behavior, most lunch containers are built for stationary use—meant to be set down, fully opened, and consumed at once. Through market research, I identified a gap between portability and accessibility: products prioritize containment, insulation, and subdivision, but rarely support eating, sharing, or hydrating while in motion. In response, I designed a selectively accessible system with a single fold-back lid and magnetically attached components for quick, intuitive access to food, utensils, and a water bottle while wearing it. The hybrid construction—fabric wrapped around more rigid silicone and foam—balances structure, comfort, insulation, and machine washability. The result is a lunch system optimized not just for carrying food, but for using it efficiently throughout the day.
Context
Inspiration for Research
For this project, I wanted to design a lunch box that allowed its users to eat while they walked. My goal was to create a container that was most importantly, quick to access. I noted that other lunch boxes on the market rarely focused on this kind of on-the-move access.
I was inspired by a coding student whom I saw walking through campus who was simultaneously holding his laptop up to his face and coding. While I would encourage a world where people sit down to eat, the reality is that we don't always have time to slow down. I wanted to create a lunch box that was suited for this kind of moment. But first, I needed to find out if this was something that people actually wanted or needed, so I proceeded to do research on the topic of lunchboxes.
Market Research
For this initial phase of the project, I identified some of the types of lunch boxes that were popular on the market and categorized them based on what they aimed to offer their users. I wanted to create a lunch box that addressed some unmet needs.
Research Summary
1. Gap: Access is designed for one person in a stillness enviroment, not in movement.
Most lunchboxes assume you will stop, set them down, and open multiple container for one person.
Solution: A wearable, front-facing system with a single fold-back lid instead of multiple tiny closures.
The attached lid simplifies interaction and allows controlled access while in motion. Magnetically
stabilized container for security. Access makes sharing more comfortable.
2. Gap: Water, utensils, and food are treated as separate elements.
Hydration and tools are often external or awkwardly stored.
Solution: Fully integrated magnetic system:
-
Water bottle straps in magnetically for secure, quick access
-
Main container seats magnetically into an indented silicone base for stability
-
Utensils mount magnetically inside the lid for intuitive retrieval
3. Gap: Opening systems, disrupts structure, and increases spill risk.
Traditional systems have many small and complex lids or one lid that exposes all contents and relies on heavy sealing.
Solution: A single foldable lid with rounded geometry allowing one section to be accessed without shifting or spilling the others.
4. Gap: Material choices not optimal.
Rigid plastic boxes lack comfort and gather bacteria. Soft bags have no strcutural integrety making things harder to access. Silicones and Woods trap bacteria and are harder to clean.
Solution: Hybrid construction—machine-washable fabric wrapping a hard foam, combined with a more rigid outer layer for structure and comfortable wearability.

Packing Meal
When at home, open and fill the container and water bottle with the desired meal and snacks. Shut the carrier and close the clips around each side to secure it. Put on your lunch box and you are ready to go!
Out in the World
As you walk, you can slip your water bottle out the side of the lunchbox for easy hydration. When you are ready to eat your meal, simply pull the lid upwards and hook it to the carrier case. You can either grab your spork or go in with your hand to access your meal, a system that makes it easy to share food and eat on the go.
1. Front-Facing Access
The windowed compartment visually communicates access:
-
“You can use it from here.”
-
“This is meant to be used while worn.”
-
Can grab utensil from lid and water bottle from side
-
Magnetized accessories make access even more easy
2. Attached Lid That Hooks Back
Key to accessing the food and utensils securely
-
Open and close container in movement
-
No nowhere-to-put-the-lid problem
-
No Two-handed awkwardness
-
No Surface dependency
3. Layered Subdivisions
The foldable lid solves for:
-
Sequential access
-
Partial exposure
-
Spill isolation
4. Material Strategy
Removable fabric exterior + hard foam interior is the right instinct for:
-
Soft and secure against body
-
Machine washable
-
Structured enough to contain food stable in movement
Parts
The system consists of a wearable outer shell made from machine-washable fabric layered over foam insulation and a rigid structural exterior. A removable food container seats within a rounded silicone cradle to maintain stability during movement. The interior is vertically subdivided for sequential access, controlled by a single attached fold-back lid. Utensils mount magnetically to the inside of the lid, and a water bottle attaches magnetically to the exterior for integrated, on-body access. Rounded internal geometries reduce residue buildup and simplify cleaning while maintaining structural containment..
Ideation
This part of the process was about ideating as many possible solutions for an easily accessible, compact, and travel-friendly meal experience. I explored a range of collapsable, flexible, and modular designs. I wanted to include. the storage and protection of both liquid and solid foods, as well asequally accessible cutlery and a single-handed efficient opening mechanism.
Preliminary Models
Exploratory Model of its Components
Here, I wanted to illustrate the different components of my lunch box. Its main parts; are the food container, the carrier case around it, and the straps (+ clips) that allow the lunch box to attach to the user's body.
In this model, I explored a version of the food container that had an extruded portion that went beyond the gap in the carrier case. This gap is meant to create a place for the user to access the food while the lunch box is still attached to the body. The extrusion combined with the gap is meant to allow ample space for the hand to easily access the open container.
Explorations in flexible materials
Preliminary material explorations made in different bendable materials to acchive a desired stiffness.
Exploratory Model of Cointainer
In this set of models, I wanted to prototype the food container with its curvature and proportions. I discovered that the milling machine and the foam I was using were not very compatible and so I had to create the next container by hand sanding. For each model, I translated my discoveries into notes.
Explorations in stiffness and bendability
preliminary material explorations made in cardboard, fabric, rubber and foam
Exploratory Model of seams and details
In this model, I wanted to illustrate a couple more details than in the previous model, such as the handle of the lunch box and the shapes it might take, the way that the food container lid opens and closes within the carrier case, and how the lid how might attach to the carrier case while remaining open. I also explored a set of possible materials and the desired stiffness of its parts.
Fabric and Foam model
preliminary material explorations made in fabric and foam
Fabric model was too flimsy to hold the hook for the lid to open, harder flex materials required in further explorations
This model was made out of crafting foam, lined with fabric. I made the handle part of the overall form, added the hook for the lid, and used the seams to enhance its overall form.
Process
Paper model was too stiff in some areas, needed to be scored so it could be bent, and was too weak to hold the heavyness of the container.
preliminary material explorations made of laser cut paper
Paper
model
This model was made out of lasered cut paper stock, I wanted to
explore what parts of the model would benefit from the the stiffness of this material. In this variation, I cut out the base of the lunchbox to observe how the container might fit in this gap and make the design more sturdy. I also experimented with a different kind of lid, this one was made out of foam, and while this lid was more flexible than my previous one, it wasn't sturdy enough to model the feeling of a snap fit.
"on the go " Lunch Box
Throughout the development process, I explored multiple structural and material prototypes using foam, paper, cardboard, fabric, and 3D-printed components to test form, subdivision logic, and wearable configuration. These iterations helped clarify the balance between flexibility and structure, as well as how the system could maintain stability while being accessed in motion. While the core architecture was validated, further refinement is needed—particularly in strap design and load distribution, which were not fully user-tested. Market research played a critical role in shaping the direction of the project, revealing a clear gap between portability and accessibility in existing lunch systems. This process reinforced the importance of aligning mechanical decisions with real behavioral patterns, and highlighted the need for continued material exploration and user feedback to bring the system to full resolution.
