Solution Overview
Problem
Existing pet feeders have complex structures, are difficult to transport, prone to grain jamming, and lack effective moisture-proof and insect-proof properties.
Innovation Solution
An intelligent push-pull anti-cockroach automatic pet feeder with a simplified design featuring a gear box-driven grain conveying system, infrared inductor, stainless-steel basin, and anti-cockroach sealing strip, which ensures easy grain output and prevents insect and moisture ingress, allowing for compact stacking and transportation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If existing pet feeder structures are used, then feeding function is achieved, but structure complexity increases and transportation becomes difficult
Solution Approach 1:
The feeding bowl is nested within the grain barrel, and the grain barrel is nested within the base assembly. This nested configuration allows the entire feeder to be compacted to a minimal volume for transportation and storage, while still providing full feeding functionality when deployed.
Solution Approach 2:
The base serves multiple functions: it houses the driving device for grain conveyance, provides structural support for the nested components, and acts as the outer container when the feeder is compacted for transport. This multi-functionality reduces the number of separate parts needed.
2Productivity
If complex grain conveying systems are used, then grain output is achieved, but grain jamming occurs
Solution Approach 1:
The grain toggling sheet extracts the grain jamming problem by providing a smooth, continuous surface that guides grain flow from the grain barrel to the feeding bowl, preventing grain from getting stuck at transition points. The toggling sheet acts as a dedicated grain flow path separate from the mechanical conveying components.
Solution Approach 2:
The grain conveying push block features a grain leakage-preventing blocking sheet at its front end, creating a localized sealing quality that prevents grain from leaking or jamming at the outlet interface while allowing smooth grain flow during the pushing action.
3Ease of operation
If open grain outlets are used, then grain access is easy, but insect and moisture ingress occurs
Solution Approach 1:
The anti-cockroach sealing strip uses a flexible sealing mechanism that maintains contact between the grain conveying push block and the grain barrel opening. This flexible seal prevents insects and moisture from entering while allowing the push block to move freely during grain conveyance operations.
Solution Approach 2:
The sealing system is self-regulating: when the grain conveying push block moves forward to discharge grain, the sealing strip automatically maintains contact to prevent infiltration. The system provides its own sealing action through the mechanical interaction of components without requiring additional active sealing mechanisms.
