Pet Feeder Using Original Packaging Bag as Main Container
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pet feeders require manual transfer of feed from packaging bags to smaller storage bins, necessitating multiple refills and re-closing, which is time-consuming, labor-intensive, and prone to leakage and pest attraction.
Innovation Solution
A pet feeding machine that uses the original feed packaging bag as the main container, equipped with a funnel, hole opener, and baffle to facilitate automatic feeding without the need for repeated refilling or re-closing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of stationary object
If the original feed packaging bag is used as the main container, then the storage capacity is improved and multiple refilling operations are eliminated, but the device structure becomes more complex requiring additional components like funnel and hole opener
Solution Approach 1:
The patent places the original feed packaging bag inside the funnel structure, which is nested within the material box. The hole opener is positioned inside the funnel, creating a nested arrangement where smaller components are housed within larger ones. This nesting approach allows the system to accommodate the large-volume packaging bag while integrating multiple functions (opening, funneling, storage) into a compact overall structure.
Solution Approach 2:
The funnel serves multiple functions: it acts as a structural support for the packaging bag, provides a chute for feed flow, and houses the hole opener mechanism. The material box simultaneously serves as the storage container and the base structure for the entire feeding system. This multi-functionality reduces the need for separate components, thereby managing device complexity while maintaining large storage capacity.
2Device complexity
If manual transfer of feed from packaging bag to storage bin is performed, then the device structure remains simple, but time consumption and labor intensity increase due to multiple refilling operations
Solution Approach 1:
The system is pre-configured with the funnel and hole opener positioned to receive the packaging bag. The hole opener is designed to automatically create an opening in the bag when placed in position. This preliminary arrangement of components eliminates the need for manual intervention during the feeding process, allowing the user to simply place the bag and initiate operation, thereby saving time without requiring complex automated mechanisms.
Solution Approach 2:
The hole opener automatically creates the opening in the packaging bag when the bag is placed in the funnel. The funnel structure naturally guides the feed flow from the bag to the material box without requiring manual pouring or transfer operations. This self-service mechanism eliminates repetitive manual refilling actions, significantly reducing time consumption while maintaining a relatively simple device structure.
3Ease of operation
If the packaging bag is opened and left unsealed, then feed access is improved, but leakage and pest attraction problems worsen
Solution Approach 1:
The patent extracts the opening function from the general bag structure by incorporating a dedicated hole opener mechanism. This specialized component creates a controlled opening specifically for feed dispensing, separating the feeding function from the storage function. The opening is precisely where needed (at the bottom of the funnel) and is created in a controlled manner, preventing uncontrolled leakage while maintaining easy feed access during operation.
Solution Approach 2:
The funnel acts as an intermediary structure between the packaging bag and the material box. It controls the feed flow path, guiding feed from the opened bag through the funnel chute to the storage box. This intermediary structure prevents feed from leaking outside the intended path and protects against pest attraction by containing the feed within the controlled funnel-maternal box system, while still allowing easy access to the bag for refilling.
4Device complexity
If manual pouring of feed is performed, then no additional components are needed, but control precision and energy expenditure increase due to the need for strength and precise control
Solution Approach 1:
The patent replaces the manual mechanical action of lifting and pouring the bag with a gravity-based flow system. The funnel structure utilizes gravity to naturally guide feed from the bag through the chute to the material box. The hole opener creates an opening that allows feed to flow freely under gravity's influence, eliminating the need for the user to exert strength or maintain precise control during the transfer process. This substitution of manual mechanical control with passive gravitational flow significantly improves ease of operation while keeping the device structure simple.
