Adjustable Discharging Hole in Pet Feeder via Movable Baffle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional automatic pet feeding apparatuses have a fixed discharging hole size, which cannot be adjusted, leading to issues with pet food of different sizes becoming lodged and an inability to control the amount of food ejected, limiting their functionality.
Innovation Solution
A discharging adjustment structure comprising a movable baffle and fixing member within the storage chamber, allowing the size of the discharging hole to be adjusted by moving the baffle relative to the fixing member, enabling the apparatus to accommodate pet food of varying sizes and adjust the ejection amount.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the discharging hole size is kept constant, then the structure is simple, but the apparatus cannot accommodate pet food of different sizes and cannot adjust the ejection amount
Solution Approach 1:
The patent applies the dynamics principle by making the baffle movable rather than fixed. The baffle can be adjusted to different positions to change the discharging hole size, transforming a static structure into a dynamic one that adapts to different pet food sizes while maintaining reasonable structural complexity
Solution Approach 2:
The patent implements parameter changes by allowing the discharging hole size to be variable through baffle adjustment. This enables the system to change the critical parameter of hole size to accommodate different pet food dimensions and control ejection amounts, directly resolving the adaptability issue
2Quantity of substance
If a small amount of pet food is ejected, then the apparatus prevents food from becoming stuck, but the apparatus cannot reward pets with larger amounts of food
Solution Approach 1:
The patent uses parameter changes by varying the discharging hole size through baffle adjustment to control the quantity of pet food ejected. By changing the hole size parameter, the system can eject different amounts of food without modifying the ejection mechanism itself, thus avoiding increased complexity
3Adaptability or versatility
If the discharging hole size is not adjustable, then the manufacturing is simple, but pet food of different brands and types easily become lodged
Solution Approach 1:
The patent applies dynamics by implementing a movable baffle that allows the discharging hole size to be adjusted. This dynamic adjustment capability enables the apparatus to accommodate different pet food types and brands without complicating the manufacturing process, as the adjustment mechanism is integrated into the existing structure

AI summary
A feeding apparatus includes a storage chamber, an ejection channel and a discharging adjustment structure. The storage chamber has a discharging hole. The ejection channel communicates with the storage chamber through the discharging hole. The discharging adjustment structure is disposed in the storage chamber and includes a fixing member and a baffle. The fixing member is disposed on a side wall of the storage chamber and is adjacent to the discharging hole. The baffle is movably disposed on the fixing member, and one end of the baffle is adjacent to the discharging hole.
