Pet Feeder Quantitative Dispensing and Moisture Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pet feeders lack quantitative food dispensing, are prone to moisture deterioration due to lack of moisture-proofing, and often result in food blocking, leading to inadequate or excessive feeding and potential health issues for pets.
Innovation Solution
A pet feeder design featuring a shell with a fodder vessel, a driving mechanism, and vanes that divide the vessel into equal blanking grooves for controlled food dispensing, along with moisture-proofing measures such as a seal ring and dryer packages for absorption, and an anti-blocking mechanism to prevent food jams.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If food is directly discharged without quantitative control, then the device complexity is reduced, but the feeding precision deteriorates leading to insufficient or excessive food dispensing
Solution Approach 1:
The fodder vessel is divided into multiple equal blanking grooves by vanes, with each groove serving as an independent quantitative unit. This segmentation allows precise control of food portions while keeping the overall structure simple and manufacturable.
2Reliability
If no moisture-proof measures are implemented, then the device complexity is reduced, but the food quality deteriorates due to moisture deterioration
Solution Approach 1:
A removable seal ring is installed at the bottom of the fodder vessel to isolate the food storage area from moisture. The seal ring can be taken out for cleaning or replacement, providing effective moisture protection while maintaining simple device structure.
3Reliability
If no anti-blocking mechanism is provided, then the device complexity is reduced, but the feeding reliability deteriorates due to food blocking
Solution Approach 1:
The vanes are designed to extend slightly beyond the blanking grooves to form guide surfaces that preliminarily direct food flow before discharge. This preliminary action prevents food blocking by ensuring smooth flow paths, while adding minimal structural complexity.
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
Enables precise, quantitative food dispensing, prevents moisture-related issues, and ensures continuous feeding by using a driving mechanism with vanes and moisture-absorbing components, while the anti-blocking feature prevents food jams, ensuring pets receive the right amount of food consistently.
Implementation Method 1
a driving mechanism, a driving medium and a micro switch are set on the mounting base; the driving mechanism drives the driving medium to rotate... the driving medium is provide with a rotation shaft connected with and driven itself, and many even-distributed vanes are set on the rotation shaft
Implementation Method 2
the driving mechanism is composed of a motor, a first pulley, a second pulley and a worm; the motor is connected with the first pulley through a first belt; the first pulley is connected with the second pulley through a second belt, the worm is fixed to the central position of the second pulley, and the turbine engages with the worm
Implementation Method 3
a blanking tube is also set inside the shell, and an infrared sensor is set on the blanking tube
