Pet waste removal device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods of pet waste removal are time-consuming and labor-intensive, and do not adequately address the sanitation of areas where pet waste is located, which can contribute to the spread of harmful bacteria and pathogens.
Innovation Solution
A pet waste removal device equipped with a handlebar assembly, wheels, a waste collecting aperture, a reverse axle with rakes, a mesh waste catcher, an internal hose, a vacuum bag, and a sanitizer compartment to streamline the removal and sanitation process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional manual methods are used for pet waste removal, then the device complexity is low, but the productivity is low and labor intensity is high
Solution Approach 1:
The patent combines multiple functions (waste collection, vacuuming, and sanitization) into a single integrated device. The main body houses both the vacuum mechanism and sanitizer compartment, allowing simultaneous or sequential operation of waste removal and sanitation functions, thereby improving productivity without requiring multiple separate tools
Solution Approach 2:
The device performs multiple functions: the wheels propel the device forward, the reverse axle with rakes collects waste, the internal hose vacuums waste into the bag, and the sanitizer compartment disinfects the area. This multi-functional design increases productivity by eliminating the need for separate collection and sanitation steps
2Loss of time
If conventional manual removal methods are used, then the device complexity is low, but the time consumption is high
Solution Approach 1:
The device enables continuous operation where the wheels continuously propel the device forward, the reverse axle continuously rotates to gather waste, and the internal hose continuously vacuums waste into the bag. This continuous action reduces the time required compared to intermittent manual collection methods
Solution Approach 2:
The reverse axle with rakes preliminarily gathers and concentrates the pet waste onto the path of the internal hose, preparing it for efficient vacuuming. This preliminary gathering action reduces the time needed for the vacuuming process by pre-concentrating the waste in one location
3Object-affected harmful factors
If conventional removal methods are used, then the device complexity is low, but the sanitation function is insufficient
Solution Approach 1:
The patent merges the waste removal function with the sanitation function in a single device. The sanitizer compartment is integrated into the main body and can be activated to spray sanitizer on the area where waste was collected, providing immediate disinfection and reducing harmful factors without requiring a separate sanitation step
Solution Approach 2:
The device performs sanitation as a preliminary or immediate follow-up action to waste removal. The sanitizer compartment can be activated to disinfect the area before harmful factors have a chance to spread, preventing contamination rather than just removing waste
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 device efficiently collects and sanitizes pet waste, reducing the time and effort required for lawn care while protecting families and pets from harmful diseases, and is suitable for various surfaces and environments.
Implementation Method 1
a reverse axle including a plurality of rakes disposed on a surface of the reverse axle, wherein the reverse axle rotates in a direction opposite to the rotation of the plurality of wheels to allow the plurality of rakes to pick up the pet waste and introduce the pet waste through the waste collecting aperture
Implementation Method 2
an internal hose to suck the pet waste up from the mesh waste catcher, a vacuum bag connected to the main body to receive the pet waste therein, such that the internal hose directs the pet waste from the mesh waste catcher into the vacuum bag
Implementation Method 3
a sanitizer compartment to store sanitizer therein, the sanitizer compartment including a plurality of sanitizer compartment spray nozzles disposed at a bottom surface of the sanitizer compartment to spray the sanitizer out from the sanitizer compartment
