Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pet food elevating devices are not easily operable by individuals with reduced mobility and often require obtrusive installations, making it difficult for elderly persons to feed and water pets without bending or stooping.
Innovation Solution
A pet food elevating device featuring a food platform with a wheel assembly and vertical track, coupled with a pulley and rope system, allowing for easy height adjustment and secure positioning without requiring complex installation or heavy user effort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a pet food elevating device is designed to be easily operable by persons with reduced mobility, then ease of operation is improved, but device complexity may increase
Solution Approach 1:
The patent replaces complex mechanical control systems with a simple rope-and-pulley mechanism. Instead of using motors, gears, or electronic controls, the device uses a basic pulley system where a single rope pass through an upper pulley to raise and lower the food platform, dramatically simplifying the mechanical system while maintaining ease of operation for persons with reduced mobility
Solution Approach 2:
The device enables self-service operation through its simple rope mechanism that allows users to independently raise and lower the food platform without assistance. The projection-and-ring locking system further enables self-service by allowing users to securely position the platform at desired heights without requiring complex locking mechanisms or external help
2Shape
If the device is designed to be unobtrusive in installation, then aesthetic appearance is improved, but installation flexibility may worsen
Solution Approach 1:
The patent transitions from floor-based or wall-mounted installations to a vertical track system mounted on walls or door frames. This dimensional change allows the device to utilize vertical space efficiently, creating a sleek profile that is unobtrusive aesthetically while maintaining installation flexibility through adaptation to various vertical surfaces including walls and door frames
3Ease of operation
If the wheel assembly is designed to slide smoothly in the vertical track, then ease of operation is improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent introduces a rope as an intermediary element between the user's manual input and the food platform movement. Instead of requiring direct manual manipulation of the platform or complex mechanical controls, the rope serves as a mediator that transmits force smoothly through the pulley system, reducing the impact of manufacturing tolerances on operational smoothness while maintaining ease of use
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
Enables safe and convenient feeding of pets at elevated heights, reducing strain on users with mobility issues and allowing for easy cleaning of the area beneath, while being unobtrusive in design.
Implementation Method 1
an upper pulley, and a rope movably engaged with the pulley
Implementation Method 2
a wheel assembly having wheels coupled to the food platform, a vertical track for slidably receiving the wheels

AI summary
A pet food elevating device having a food platform and wheels coupled to the food platform with a vertical track positioned to slidably receive the wheels. A rope is movably engaged with an upper pulley positioned to allow the pet food elevating device to be raised to a desired elevation within the vertical track. A first end of the rope is coupled to the food platform, and a second end of the rope is available to a user of the pet food elevating device to raise or lower the food platform. The second end of the rope may be secured to hold the pet food elevating device at a desired elevation.
