Shovel Shaft Shock-Absorbing Coating for Uneven Snow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shovel assemblies are ineffective in removing snow from uneven or cracked surfaces without jarring the operator, as they fail to provide adequate protection and stability during use on such surfaces.
Innovation Solution
A shovel assembly comprising an elongated shaft with a shock-absorbing coating, a handle sub-assembly, and a blade implement with guide members that allow for smooth operation on uneven surfaces by distributing the force of the user's push parallel to the ground, reducing jarring and enhancing stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional shovel assembly is used on uneven or cracked surfaces, then snow removal function is achieved, but the operator experiences jarring and instability
Solution Approach 1:
The shovel assembly incorporates a shock-absorbing coating applied to the shaft before use. This coating is specifically designed to cushion impacts when the shovel encounters uneven or cracked surfaces, reducing the jarring transmitted to the operator's hands and arms.
Solution Approach 2:
The shock-absorbing coating acts as an intermediary layer between the rigid shaft and the operator's hands. This intermediate layer absorbs and dissipates impact forces, preventing direct transmission of shocks to the operator while maintaining the structural integrity of the shaft.
2Productivity
If the blade implement is designed for effective snow engagement, then snow removal efficiency is improved, but the blade may become unstable on uneven surfaces
Solution Approach 1:
The blade implement incorporates a flexible coating or film layer that allows the blade to conform to uneven surfaces. This flexible layer maintains stable contact between the blade edge and the ground, preventing bounce and instability while preserving the blade's cutting and pushing effectiveness.
Solution Approach 2:
The blade implement uses materials or coatings with specific physical properties (such as elasticity or damping characteristics) that change how the blade interacts with uneven surfaces. These parameter changes allow the blade to adapt to surface variations, maintaining stability without sacrificing snow engagement capability.
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
Enables the efficient removal of snow from uneven surfaces without jarring the operator, providing protection and stability through the use of shock-absorbing materials and guide members that facilitate smooth displacement over uneven terrain.
Implementation Method 1
The shaft is provided with a shock-absorbing coating that reduces the transmission of impact forces to the operator when the shovel blade encounters uneven or cracked surfaces
