Rotatable Handle Manure Scraper for Push-Pull Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing scraping devices are limited in their ability to efficiently push or pull manure towards a collection point, often requiring separate tools for each function.
Innovation Solution
A scraper device with a first portion forming an angle with a second portion, equipped with a handle that can be rotated to facilitate both pushing and pulling manure by adjusting its position on the support surface, allowing the same device to serve double duty.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single scraper device is used for both pushing and pulling manure, then device versatility is improved, but the structural complexity increases due to the need for rotatable handle mechanism
Solution Approach 1:
The scraper device incorporates a rotatable handle that can be positioned in multiple orientations (pushing position and pulling position) to enable a single device to perform multiple functions - both pushing and pulling manure - thereby achieving multi-functionality without requiring separate tools for each operation
Solution Approach 2:
The handle is designed with rotational capability, allowing it to dynamically change its orientation relative to the scraper body. This dynamic adjustment enables the same physical structure to adapt between different operational modes (pushing and pulling) by rotating the handle to the appropriate angle, thus resolving the contradiction between versatility and structural complexity
2Productivity
If separate tools are used for pushing and pulling manure, then operational simplicity is maintained, but productivity decreases due to the need to switch between multiple tools
Solution Approach 1:
The scraper device integrates both pushing and pulling capabilities into a single tool through the rotatable handle mechanism, eliminating the need to switch between separate pushing and pulling tools. This multi-functionality directly improves productivity by reducing tool-switching time and maintaining continuous operational flow
3Ease of operation
If the handle is fixed in position, then device simplicity is maintained, but ease of operation deteriorates as it cannot adapt to different scraping directions
Solution Approach 1:
The handle incorporates a rotational mechanism that allows it to be adjusted between different positions (pushing and pulling orientations). This dynamic capability enables the handle to adapt to different scraping directions and operational requirements, significantly improving ease of operation while adding only moderate structural complexity through the rotation mechanism

AI summary
A manure scraping assembly includes a scraper that has a first portion forming an angle with a second portion. The scraper is positionable in a pushing position to push manure on the support surface. Conversely, the scraper is positionable in a pulling position to pull manure on the support surface. A handle is removably attached to the scraper and the handle can be gripped by a user thereby facilitating the scraper to be pushed or pulled. The handle angles upwardly at a substantially diagonal axis with respect to the first portion of the scraper when the scraper is positioned in the pushing position. Moreover, the handle angles upwardly at a substantially diagonal axis with respect to the second portion of the scraper when the scraper is positioned in the pulling position.
