Pet Feeder Sealing Cover Rotation and Control Interface Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pet feeders lack control over food distribution quantity, are cumbersome for multi-meal loading, fail to stimulate pets' appetite, and have complex, inconvenient interfaces that can be accidentally triggered by pets, leading to unintended shutdowns and feeding issues.
Innovation Solution
A timed calling type pet feeder with multiple food storage boxes, a rotating mechanism driven by a motor and gear set, an appetite stimulating module with sound playback, and a control module for timed feeding, combined with a sterilization module and key self-locking function to prevent accidental operation, ensuring precise and safe feeding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple food compartments are used to enable multi-meal loading, then the feeder can store food for multiple meals at once, but the device complexity increases and the interface becomes more prone to accidental triggering
Solution Approach 1:
The control interface is segmented into a main operation area and a separate timed calling operation area, with the timed calling area positioned away from the main interface. This spatial segmentation allows the feeder to have multiple food compartments and complex functionality while preventing accidental triggering by isolating critical controls from areas where pets might inadvertently touch.
2Ease of operation
If the control interface is positioned for easy human access, then ease of operation improves, but pets can more easily accidentally trigger the keys
Solution Approach 1:
The timed calling operation interface is positioned in a different spatial dimension - specifically, it is located away from the main control panel in a separate area that is less accessible to pets but still convenient for human operation. This dimensional separation resolves the contradiction by allowing the interface to be easily accessible to humans while being less accessible to pets.
3Device complexity
If a single food container is used, then the device complexity is reduced, but the feeder can only be loaded with food for one meal at a time
Solution Approach 1:
The food storage system is segmented into multiple compartments, each capable of holding food for separate meals. This segmentation allows the feeder to provide multiple meals throughout the day without requiring manual intervention for each loading, significantly improving feeding efficiency while maintaining manageable device complexity through modular design.
4Device complexity
If the feeder provides only automatic opening function, then the device complexity is minimized, but it cannot control the amount of food distributed each time
Solution Approach 1:
The feeder incorporates a timed calling function that allows pets to independently trigger feeding at scheduled times by interacting with a dedicated button. This self-service mechanism enables precise control over food distribution timing and amount without requiring complex automated sensors or monitoring systems, as the pet itself activates the feeding process at predetermined intervals.
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
The feeder provides automatic and manual feeding options, stimulates pets' appetite, prevents accidental operation, maintains food freshness through sterilization, and ensures accurate and timely feeding, enhancing pet health and owner convenience.
Implementation Method 1
The rotating mechanism includes a rotary casing, a driving motor, and a gear set fixedly connected to an output shaft of the driving motor
Implementation Method 2
The gear set is meshed with the internal teeth through multiple decelerations

AI summary
A timed calling type pet feeder capable of preventing mistaken touch includes a bottom shell. A feeding tray matching with the bottom shell and embedded in the bottom shell is arranged on the bottom shell. N food storage boxes are uniformly arranged on the feeding tray along a circumferential direction in a sunken manner. The N is a positive integer greater than or equal to 3. A sealing cover configured to seal N−1 food storage boxes is arranged on the bottom shell. A rotating mechanism configured to drive the sealing cover to rotate, a control module configured to drive the rotating mechanism to operate, and an appetite stimulating module configured to cooperate with the control module to implement interaction are arranged in a center of the bottom shell. The control module includes a printed circuit board (PCB). The PCB is programmed with a timing module, a key module, and a display module. The appetite stimulating module includes a recording module configured to record a sound for urging a pet to eat and a speaker configured for timed playback of the sound.
