Automatic Wet Pet Food Dispenser with Refrigerated Sealed Pouches
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic pet feeders require significant manual involvement and have limited capacity for wet pet food, leading to rapid bacterial growth and reduced shelf life, while dry food solutions are unsuitable for pet health.
Innovation Solution
An automated pet food dispenser that uses sealed cartridges, a processing system, and a load cell to measure and regulate food quantity, combined with refrigeration to maintain freshness and extend shelf life, allowing for customizable feeding schedules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If wet pet food is stored in contemporary automatic feeders, then the food can be dispensed automatically, but the shelf life is rapidly reduced and bacterial growth increases
Solution Approach 1:
The food storage system is segmented into individual sealed pouches, each containing a complete meal. This segmentation prevents contamination between meals and maintains the integrity of each pouch until dispensing, thereby preserving shelf life and preventing bacterial growth while enabling automatic feeding.
Solution Approach 2:
A refrigeration unit is introduced as an intermediary component to maintain the pouches at optimal storage temperature. This intermediary system preserves food freshness and inhibits bacterial growth, resolving the contradiction between automation and food reliability.
2Ease of operation
If wet pet food is removed from sealed containers, then it can be dispensed, but the shelf life is reduced and bacterial growth increases rapidly
Solution Approach 1:
The system performs preliminary sealing of individual pouches to preserve food quality. Each pouch remains sealed until the moment of dispensing, preventing premature exposure to contaminants and maintaining food safety while enabling convenient automatic dispensing.
Solution Approach 2:
The refrigeration unit acts as an intermediary that maintains optimal storage conditions for sealed pouches, preserving food safety and shelf life while the dispensing mechanism provides ease of operation.
3Extent of automation
If dry pet food is used in automatic feeders, then feeding is automated, but the solution is not suited to pet digestive health
Solution Approach 1:
The system changes the physical state parameter of the food from dry to wet, providing nutrition that is appropriate for pet digestive health while maintaining automation through the dispensing mechanism. The wet food in sealed pouches can be automatically dispensed without compromising pet health.
4Productivity
If manual scooping of wet pet food is required, then some automation is achieved, but labor-intensive handling remains
Solution Approach 1:
The system is designed to be self-service, with the dispensing mechanism automatically retrieving and dispensing food from sealed pouches without requiring manual scooping or handling. The user simply loads the pouches, and the system handles all subsequent feeding operations autonomously.
Solution Approach 2:
The manual mechanical action of scooping is replaced with an automated dispensing mechanism that uses controlled mechanical movement to transfer food from the pouch to the bowl, eliminating labor-intensive handling while maintaining feeding efficiency.
5Ease of operation
If small carry capacity chambers are used, then manual scooping is possible, but the meal capacity is limited
Solution Approach 1:
The system transitions from a single small chamber design to a multi-dimensional storage solution using multiple sealed pouches that can be stacked or arranged vertically. This dimensional change increases the total food capacity while maintaining ease of operation through simple pouch insertion and removal.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The dispenser maintains wet pet food freshness for up to a week with reduced bacterial growth and increased meal capacity, eliminating manual handling and ensuring proper nutrition for pets.
Implementation Method 1
One aspect includes a refrigeration unit that maintains the wet pet food at a temperature that is lower than an ambient temperature
Implementation Method 2
A load cell or other weighing mechanism may be used to measure a weight of a dispensed quantity of wet pet food

AI summary
Systems and methods for automated pet food dispensing are described. One apparatus includes a receptacle configured to hold a sealed container containing wet pet food. The apparatus may include an electrically-operated plunger configured to interface with the receptacle. A processing system may be connected to the electrically-operated plunger. In one aspect, the processing system is configured to initiate a pet feeding event by actuating the plunger to interface with the receptacle, puncture the sealed container, and dispense the wet pet food into the food bowl. The processing system may maintain a time history to determine one or more future pet feeding events.
