Solution Overview

Problem

Existing pet feeders are limited to a single food bin, unable to simultaneously feed multiple pets or provide various foods in one meal, leading to issues like food pollution and pet discomfort.

Innovation Solution

A pet feeder with multiple non-communicating food distribution bins, each paired with a dedicated feeding assembly, featuring movable food conveying mechanisms and control assemblies to independently distribute different foods to a pet eating position, controlled by a sensing and detection system.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single food bin is used, then the device complexity is reduced, but the adaptability to feed multiple pets or provide various foods is insufficient

Engineering Contradiction:

Improveability to feed multiple pets or provide various foodsVSAvoidstructure complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The food container assembly is divided into multiple independent food distribution bins (first food distribution bin, second food distribution bin, etc.), each capable of storing different types of food. This segmentation allows the feeder to provide various foods to multiple pets simultaneously while maintaining independent control over each food type, thus improving adaptability without excessive complexity increase.

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If multiple food distribution bins are provided with separate feeding assemblies, then the ability to independently convey different foods is improved, but the device complexity increases

Engineering Contradiction:

Improveindependent food distribution capabilityVSAvoidfeeding assembly structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Multiple feeding assemblies are designed with identical or similar structures, each capable of independently conveying different food types from respective distribution bins to feeding positions. This universal design approach allows independent control over each food type while using standardized components, improving adaptability without proportionally increasing overall system complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Object-affected harmful factors

If food distribution bins are in communication with each other, then the structure is simplified, but food pollution occurs between different food types

Engineering Contradiction:

Improvefood pollutionVSAvoidfood channel structure

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The food distribution bins are designed as non-communicating independent chambers, each with its own separate food outlet and feeding assembly. This complete segmentation prevents different food types from mixing or contaminating each other, effectively eliminating food pollution issues while maintaining manageable structural complexity through modular design.

Inventive Principle:

Principle #1Segmentation

4Object-affected harmful factors

If a single food channel is shared, then the device complexity is reduced, but food contamination between different foods occurs

Engineering Contradiction:

Improvefood contaminationVSAvoidfood channel structure

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

Each food distribution bin is equipped with its own dedicated food channel that does not communicate with other food channels. This segmentation ensures complete isolation between different food types throughout the conveying process, preventing contamination while maintaining manageable complexity through standardized independent channel designs.

Inventive Principle:

Principle #1Segmentation

5Manufacturing precision

If food conveying mechanisms are stationary, then the device complexity is reduced, but the control precision over food conveying amount is insufficient

Engineering Contradiction:

Improvefood conveying amount controlVSAvoidcontrol system structure

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

Food conveying mechanisms are designed to move between different positions (first position for receiving food, second position for dispensing food). This dynamic positioning capability allows precise control over the amount of food conveyed by adjusting the movement distance and timing, achieving accurate portion control while maintaining relatively simple control system architecture through straightforward motion control.

Inventive Principle:

Principle #15Dynamics

AI summary

The present application relates to a pet feeder. The pet feeder includes: a food container assembly, feeding assemblies and a base, in which, the food container assembly and the feeding assemblies are connected to the base; the food container assembly is used for storing food, and the feeding assemblies are used for conveying the food stored in the food container assembly to a pet eating position; the food container assembly includes at least two food distribution bins which are not in communication with each other; and the feeding assemblies correspond to the food distribution bins in quantity and are matched with the food distribution bins one by one, so that any food distribution bin can independently convey the food by means of the corresponding feeding assembly.
