Rotatable Pet Feeder Bowl for Contamination Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pet feeding bowls in automatic feeders are fixed, leading to contamination issues due to pets urinating or defecating in them, which affects the cleanliness of the eating environment.
Innovation Solution
A rotatable feeding bowl device with a base and a feeding bowl that can be rotated to a position where the pet cannot eat when not in use, equipped with a driving mechanism and sensors to automate the rotation based on the pet's presence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the feeding bowl is fixedly arranged at the bottom area of the feeder, then the pet can eat during the feeding time, but the feeding bowl cannot be put away, which may cause the pelvic cavity of the feeding bowl to be contaminated by the pet
Solution Approach 1:
The feeding bowl is changed from a fixed structure to a rotatable structure that can dynamically adjust its position between a feeding position (where the pet can eat) and a storage position (where the pet cannot access it). This dynamic positioning resolves the contradiction by allowing the bowl to be accessible when needed and inaccessible when not in use, preventing contamination while maintaining feeding convenience.
Solution Approach 2:
The solution introduces a rotational dimension to the feeding bowl's positioning, allowing it to move between different spatial locations. By adding this rotational degree of freedom, the system can transition the bowl from a static contaminated state to a dynamic state where it can be rotated away from the pet's reach, thus preventing contamination while preserving ease of operation during feeding time.
2Object-affected harmful factors
If the feeding bowl is rotatably connected to the base, then the feeding bowl can be rotated to a position where the pet cannot eat, but the device requires a driving mechanism and sensors
Solution Approach 1:
The system employs sensors to detect the pet's presence and automatically controls the driving mechanism to rotate the feeding bowl to the appropriate position. This self-service automation reduces the need for manual operation and simplifies the control logic, as the system autonomously manages the rotation based on detected conditions, thereby preventing contamination without requiring complex manual control mechanisms.
Solution Approach 2:
The sensor-based detection system provides feedback about the pet's presence to the control mechanism, which then adjusts the feeding bowl's position accordingly. This feedback loop enables the system to automatically respond to the pet's needs, rotating the bowl to a safe position when the pet is absent and to a feeding position when the pet is present, thus preventing contamination while maintaining relatively simple device architecture.

AI summary
The present disclosure provides a rotatable feeding bowl device and pet feeder, comprising a base and a feeding bowl; wherein the base is disposed on the pet feeder; one end of the feeding bowl is rotatably connected to the base, so that the feeding bowl is enabled to be rotated on the pet feeder to a first preset position where a pet cannot eat, or to a second preset position where a pet can eat. It is only put down when a pet is eating and put away when a pet is not eating, which is conducive to keeping the feeding bowl clean and preventing a pet from polluting the feeding bowl when a pet is not eating, thereby ensuring the cleanliness of pet's feeding environment and avoiding affecting pet's health.
