Shovel With Asymmetrical Tip And Segmented Head For Balance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional shovels often have small steps that limit user access and efficiency, particularly in tasks requiring deeper penetration or larger surface area for digging and debris removal.
Innovation Solution
The design includes a handle with strategically positioned grip portions and a head with a central spoon portion, intermediate planar portions, and outer planar portions, featuring a triangular spline and asymmetrical tip for enhanced penetration and a larger step area, allowing for improved balance and mechanical advantage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the step dimensions are increased to provide larger surface area, then user access and mechanical advantage are improved, but the shovel head becomes heavier and more complex
Solution Approach 1:
The shovel head is divided into distinct functional segments: a central spoon portion for digging, intermediate planar portions for step functionality, and outer planar portions for debris removal. This segmentation allows each portion to be optimized independently while maintaining overall structural integrity.
Solution Approach 2:
The step structure extends in multiple dimensions from the shovel head, creating a three-dimensional configuration that provides larger surface area for user access without significantly increasing the two-dimensional footprint of the shovel head.
2Productivity
If the tip is designed with asymmetrical angles for enhanced penetration, then digging efficiency is improved, but manufacturing precision requirements increase
Solution Approach 1:
The tip is designed with asymmetrical angles where the first side portion is oriented at a first angle relative to the axis and the second side portion is oriented at a second angle different from the first angle. This asymmetry enhances penetration capability by creating a more effective cutting edge configuration.
3Ease of operation
If the center of gravity is positioned at the handle for balanced handling, then ease of operation is improved, but the head must be heavier to compensate
Solution Approach 1:
The handle is designed with grip portions positioned to serve as counterweights, balancing the head weight. The first and second grip portions are strategically located to provide mechanical advantage and balance the center of gravity at the handle, compensating for the heavier head configuration.
4Adaptability or versatility
If multiple planar portions are added to the head for diverse functions, then versatility is improved, but device complexity increases
Solution Approach 1:
The shovel head is designed as a multi-functional tool where the central spoon portion handles digging, the intermediate planar portions provide step functionality for user access, and the outer planar portions facilitate debris removal. This universal design allows a single shovel head to perform multiple digging and debris removal tasks efficiently.

AI summary
A shovel including a handle and a head. The handle includes a first grip portion and a second grip portion spaced from the first grip portion and located adjacent the second end. The head includes a tip and a collar disposed opposite the tip and coupling the handle and the head together. The head extends along an axis passing through the tip and a rearward portion of the head adjacent the collar. A center of gravity of the shovel is coincident with the handle.
