Standing Shovel Multi-Angled Lifting Structure Ergonomics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional shovels require users to bend over, making them difficult to use for people with mobility issues, and they are not easily stackable, leading to storage challenges.
Innovation Solution
A multi-angled lifting structure with a collection element and handle configuration that reduces bending requirements, along with a self-supporting stand and interchangeable brush member, allowing for efficient material collection, lifting, and stacking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional shovel with a long cylindrical handle is used, then the user can lift and scrape material, but the user must bend over which is difficult or painful for many people
Solution Approach 1:
The lifting structure is divided into three distinct segments (first segment extending from collection element, second segment forming obtuse angle, third segment extending parallel to first segment) connected by pivot points, allowing the handle to be configured in different angles and positions to reduce bending requirements
2Ease of manufacture
If conventional shovels are stacked in storage or on retail floor, then space is saved, but they easily fall over due to their shape
Solution Approach 1:
The multi-angled configuration of the lifting structure segments creates an asymmetric shape that allows shovels to be stacked neatly together in a stable arrangement, preventing them from falling over while maintaining compact storage

AI summary
A tool adapted to collect, lift, and move material has a lifting structure attached to a collection element and at least one handle attached to the lifting structure. The lifting structure may have two or three segments. Each segment may have rails spaced apart and substantially parallel to each other with at least one cross member disposed there-between. The segments are oriented relative to one another to reduce the amount of bending required to lift material in the collection element. Adjacent segments in the lifting structure may be pivotally attached to each other. This tool can be free standing when used as a dustpan.
