Pet Waste Disposal Device with Pheromone Reservoir and Filtration Pad
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Public areas where pets are walked often become fouled with pet waste, leading to unpleasant odors and the spread of disease-carrying germs, with existing solutions like dog poop bags being inadequate in addressing the issue of germ elimination and waste disposal.
Innovation Solution
A pet waste disposal device featuring a stabilization pillar with a pheromone reservoir to attract animals, an absorption pad, a filtration pad to eliminate germs, permeable openings for drainage, a probe for contamination monitoring, a poop bag container, a supply bin, leash fastening feature, pet waste scooper, and a solar panel for lighting and rainwater management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If containers with dog poop bags are installed, then waste collection capability is improved, but germ elimination capability deteriorates
Solution Approach 1:
The patent combines multiple functions into a single integrated device: waste collection (poop bag container), germ elimination (UV-C lighting system), absorption (absorption pad), and filtration (filtration pad) are merged into one unified pet waste disposal station, resolving the contradiction by making both waste collection and germ elimination capabilities available simultaneously
Solution Approach 2:
The device performs multiple functions: collecting feces with bags, absorbing urine with an absorption pad, filtering contaminants with a filtration pad, eliminating germs with UV-C lighting, and providing information through an e-paper display. This multi-functionality addresses both waste collection and germ elimination needs in a single system
2Object-affected harmful factors
If absorption pad and filtration pad are added, then germ elimination capability is improved, but device complexity deteriorates
Solution Approach 1:
The device is divided into distinct functional modules: an absorption pad for urine absorption, a filtration pad for contaminant removal, a UV-C lighting system for germ elimination, and a poop bag container for feces collection. Each module performs a specific function and can be independently maintained or replaced, reducing overall system complexity through functional segmentation
Solution Approach 2:
The filtration pad acts as an intermediary between the absorption pad and the drainage system, filtering contaminants from urine before it drains away. This intermediary component simplifies the overall system by handling filtration in a dedicated layer rather than requiring complex integrated filtration mechanisms
3Illumination intensity
If solar panel and lighting units are added, then illumination capability is improved, but energy consumption deteriorates
Solution Approach 1:
The lighting units operate periodically rather than continuously - they are activated by motion detection sensors when pets or people approach, and the UV-C germicidal lighting operates in cycles. This periodic operation provides necessary illumination while dramatically reducing overall energy consumption compared to continuous operation
Solution Approach 2:
The solar panel on the roof of the device structure generates electricity to power the lighting units and UV-C germicidal system, making the energy-consuming components self-sufficient. The e-paper display also uses minimal energy and can be updated wirelessly, further reducing the device's energy requirements
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
Effectively attracts pets, eliminates disease-carrying germs, ensures proper waste disposal, and provides a self-sustaining and illuminated waste management system that maintains cleanliness and safety in public areas.
Implementation Method 1
The bottom part of the pillar is fitted with a pheromone reservoir, which attracts the animals to the device
Implementation Method 2
The top part of the protection frame is fitted with an absorption pad
Implementation Method 3
underneath the absorption pad, at the bottom part of the stabilization pillar, a filtration pad is located, which eliminates disease-carrying germs and decreases the PH of urine
Implementation Method 4
Underneath the absorption pad, a probe is located, which checks the level of filtration pad contamination and signals the need to replace the filtration pad
Implementation Method 5
In the top part of the pillar, a plate is located, which can be used for advertising or placing information. Above the plate, a solar panel is located, which is connected to the batteries and lighting units
Implementation Method 6
lighting units used to illuminate the pet waste disposal device and the access road/path or sidewalk

AI summary
The pet waste disposal device has a stabilization pillar mounted in a protection frame. The bottom part of the pillar is fitted with a pheromone reservoir and the top part of the protection frame is fitted with an absorption pad and then a filtration pad. At the bottom of the frame, permeable openings are located, which are used to drain the filtered urine and the rainwater in the surrounding areas. Underneath the filtration pad, a probe is located, which checks the level of filtration pad contamination and signals the need to replace the filtration pad. The pillar is fitted with a frame with a container, in which a poop bag is attached. The pillar is also fitted with a supply bin, a feature used to fasten the leash to the pillar, and a pet waste scooper.
