Pet Waste Scoop Assembly With Space-Saving Pivot Door
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pet waste scoop assemblies are inefficient in handling pet waste disposal, particularly in urban environments where pets are confined indoors or outdoors, leading to odor issues and waste management challenges.
Innovation Solution
A pet waste scoop assembly with a scoop member featuring a frame, handle, receptacle, and pivotable door, designed to collect waste efficiently by allowing it to move into a bag or receptacle through angled tines and a door mechanism that opens as the scoop is lifted, utilizing paper or wax paper bags and a handle receiver for easy assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the door is made larger to improve waste discharge, then waste collection efficiency is improved, but door intrusion into the receptacle increases reducing storage space
Solution Approach 1:
The door is positioned forward of the central vertical axis of the frame, utilizing the forward dimension rather than extending rearward into the receptacle. This dimensional repositioning allows the door to achieve sufficient size for effective waste discharge while minimizing intrusion into the receptacle storage space.
2Adaptability or versatility
If the scoop member is designed to move through grass with tines, then versatility in waste collection is improved, but device complexity increases
Solution Approach 1:
The scoop member is designed with multiple functions: the frame provides structural support and defines the passageway, while the attached tines enable the scoop to penetrate grass and retrieve waste. This multi-functional design allows a single component to perform both structural and grass-penetration functions, reducing the need for separate components.
3Volume of moving object
If the door pivot connection is positioned forward of center, then door intrusion into receptacle is minimized, but door mechanism complexity increases
Solution Approach 1:
The door pivot connection is positioned asymmetrically forward of the central vertical axis rather than at the center. This asymmetric positioning creates an optimized balance between minimizing receptacle intrusion and maintaining door functionality, reducing the need for complex compensating mechanisms.

AI summary
A pet waste scoop assembly to collect pet waste is provided. The pet waste scoop assembly includes at least a scoop member, a receptacle, and a door. The pet waste scoop assembly may further include a handle. The pet waste scoop assembly may further include a bag. The scoop member may be aligned with a frame to thereby position at least one projection so that the door may freely swing without interruption from the bag that is inserted into the receptacle. The pet waste scoop assembly may be assembled in situ by connecting the scoop member and at least one of a handle and/or an adapter. The pet waste scoop may include tines that extend outward in an angled manner to collect or retrieve the pet waste material.
