Hello, this is the revised version of our third proposal——Foldable Portable Food Container for Stray Animals

The following are the detail drawings, three views and dimensions.

Sorry for the delay in sending this. We actually designed three proposals in total. Although you’ve already selected the second one, we hope this can still provide you with a bit more help.

Based on the customer’s needs, we have provided 9 design concepts.These concepts, developed from diverse perspectives and directions, aim to meet the core requirements proposed by the customer—When feeding stray animals, it should be easy for the elderly to carry, capable of withstanding harsh weather conditions, and able to prevent the internal food from rotting in a short period of time.

Liu Yahui's Initial Design Concepts

CONCEPT 1 Portable Self – Sensing Pet Bowl.

创新点：

• It has a hip rope for the elderly to carry it around easily, freeing their hands.
• A front detection camera can automatically open when it senses an animal approaching and close automatically when the animal leaves, preventing food from being contaminated.
• An internal self – lifting food container can adapt to the animal’s height.
• The internal material is food – grade silicone, and the shell is made of environmentally friendly plastic, which is easy to clean and lightweight.
• Dimensions: 200*200*80mm
• Food Capacity: 0.5kg

Innovation Points:

• It adopts a cart form, which is convenient for the elderly to transport food and reduce physical burden.
• The feeding area is integrated into the cart, making it more convenient to move and reducing the impact on the community environment.
• The feeding bowls adopt a modular design, which can be flexibly increased or decreased according to the number of animals.
• The feeding bowls can be reused, reducing plastic pollution in the neighborhood.
• Dimensions: 800*500*900mm
• Food Capacity: 2-5kg

CONCEPT 3 Folding Pet Bowl

创新之处：采用折叠式遮阳篷设计，晴天可遮阴，雨天可挡雨，刮风时可防止食物被吹倒。

• 尺寸：300* 300* 100毫米
• Food Capacity: 1kg

Liu Xiaqing's Initial Design Concepts

CONCEPT 1 Crossbody Stray Animal Feeding Bag

This is a portable single-shoulder bag, whose main body consists of a PP-material box designed for food storage. When laid flat, the box transforms into a temporary feeding container for stray animals. Once the animals have finished eating, simply reassemble the container with its shoulder strap, then sling it over your shoulder for easy transport.

CONCEPT 2 Portable Food Container for Stray Animals

This is a handheld feeding container for stray animals. Its two semicircular compartments can be detached from the main body to act as individual bowls for the animals. These bowls are completely separate (non-communicating) and crafted from PP material—when the container is sealed shut, it can hold both liquid and solid food at the same time. It also features a built-in handle for effortless carrying.

CONCEPT 3 Foldable Portable Food Container for Stray Animals

This is a hand-carried feeding container for stray animals. Its two side panels can be rotated open and flattened to function as feeding bowls for the animals. When the two parts are closed together, they remain fully non-communicating. Crafted from PP material, the sealed container allows for simultaneous storage of liquid and solid food, and it is equipped with a handle for effortless portability.

Zhao Yichen's Initial Design Concepts

CONCEPT 1 Foldable Insulated Trolley with Modular FeedingModules

This is a foldable insulated trolley with modular feeding modules, composed of a foldable aluminum alloy frame trolley, modular “feeding boxes” (slide-in type), a detachable lightweight foldable cage for cats and dogs on the side (for emergency transportation), a rainproof retractable awning, and a chassis equipped with drainage holes and a detachable base tray. The inner liner of the food compartment is fully detachable via quick-release buttons and can be placed in a household dishwasher or rinsed with a high-pressure water gun. Designed to be easy for the elderly to use with minimal burden, this trolley offers large storage capacity and relatively easy maintenance, allowing for simultaneous transportation of water, food, and a portable cage.

CONCEPT 2 Wearable Modular Backpack with a Foldable Tray

This is a wearable modular backpack with a foldable tray, suitable for urban environments with numerous alleys and staircases. It features a backpack system with multiple shoulder straps to distribute the load, along with three modular slots: a thermal food module (equipped with heat-insulating aluminum film), a foldable water bladder (fitted with a press-type faucet), and a detachable and washable stainless steel bowl set. It also comes with a pull-out foldable tray/two-wheeled hand cart; the tray can be pulled out when needed to place food on, reducing the need for bending over. The backpack is machine-washable (after removing the internal modules), while the food module and bowls can be detached for cleaning in a dishwasher or by hand rinsing; the water bladder can be turned inside out for rinsing and air-drying. This product is flexible, staircase-friendly, low-cost, and easier for the elderly to use.

CONCEPT 3 Solar-powered Street Feeding Box

This solar-powered street feeding box integrates gentle ventilation and fresh-keeping features, making it ideal for street locations requiring minimal frequent maintenance. It adopts passive/micro-active measures to slow down food spoilage and reduce the frequency of cleaning and refilling for the elderly. The box comprises a small street feeding unit with a transparent observation window, internal removable layered trays (each independently detachable for easy rotation and removal), plus a top-mounted solar panel that powers a low-energy small fan and ventilation grilles—these work together during daytime to dissipate heat and lower humidity. Additionally, it is equipped with a temperature and humidity display and a warning light, which activates to alert users against placing perishable food when temperatures exceed a preset threshold. This design not only reduces the need for the elderly to carry large amounts of food daily but also enhances street hygiene.
