Solution Overview

Problem

Existing automatic feeding devices for pets using RFID technology often result in food spillage and are less appetizing due to the use of pelleted food, which also has a shorter shelf life compared to hermetic food, and lack the ability to ensure regular feeding when pets are alone.

Innovation Solution

An automatic feeding device equipped with an RFID reader and magazines for hermetically sealed portion packages of various pet foods, featuring an automatic opening mechanism using a knife or steel wire, and a compression system to manage packaging, allowing for varied and healthy feeding schedules, even in the absence of supervision.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If pelleted food is used in automatic feeding devices, then the feeding process is automated and convenient, but food spillage occurs and the food becomes less appetizing

Engineering Contradiction:
Improveautomation of feedingVSAvoidfood spillage
Core Design Contradiction:
Extent of automationVSObject-generated harmful factors

Solution Approach 1:

The food is segmented into individual portion packages (6) that are distributed one at a time. Each package is a self-contained unit that prevents spillage during handling and dispensing, while still enabling automated feeding through the magazine system

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The portion packages utilize flexible packaging materials that can be sealed hermetically. The flexible nature allows the packages to be compressed after use, reducing volume in the magazine, while the sealed structure prevents spillage and maintains food quality

Inventive Principle:
Principle #30Flexible shells and thin films

2Extent of automation

If pelleted food is used in automatic feeding devices, then the feeding process is automated, but the food has shorter shelf life compared to hermetic food

Engineering Contradiction:
Improveautomation of feedingVSAvoidshelf life of food
Core Design Contradiction:
Extent of automationVSDuration of action of stationary object

Solution Approach 1:

The food supply is divided into multiple sealed portion packages rather than one large open container. Each package maintains hermetic sealing until use, preventing degradation and extending the effective shelf life of the food in the automatic feeder

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The portion packages are hermetically sealed to create a protective environment that excludes oxygen and moisture, preventing food degradation and extending shelf life while enabling automated storage and dispensing

Inventive Principle:
Principle #39Inert atmosphere (Inert environment)

3Reliability

If portion packages are used in the automatic feeding device, then food freshness is maintained, but the device complexity increases due to the need for opening and compression mechanisms

Engineering Contradiction:
Improvefood freshnessVSAvoidopening and compression mechanisms
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The portion packages are designed to be automatically opened by the existing magazine mechanism without requiring separate complex opening devices. The package structure itself facilitates easy opening through the magazine's normal operation

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

After the portion package is emptied, the compression mechanism compacts the empty packaging material. This reduces the volume occupied by waste packages in the magazine, effectively increasing storage capacity without adding significant complexity

Inventive Principle:
Principle #34Discarding and recovering

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 device ensures efficient, spill-free, and appetizing feeding by automatically opening and compressing hermetic food packages, maintaining food freshness and variety, while monitoring food intake and alerting owners to maintenance needs through WiFi connectivity.
