Gouging Blade Undercut and Through-Opening Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing blades for peeling substrates, such as those used in gouging planes, face high friction and handling difficulties due to their design, leading to increased force requirements and safety concerns when removing weld seams.
Innovation Solution
The blade features an undercut with a depression in the side face and a through opening, reducing friction and enhancing mechanical stability, along with a sickle-shaped cutting edge that self-centers during cutting, allowing for safer and more efficient operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the blade has a large side surface facing the ground, then the blade provides sufficient contact area for cutting, but the friction between the blade and substrate increases
Solution Approach 1:
The blade incorporates a through-opening that creates a porous structure, allowing substrate material to pass through and reducing friction between the blade's lower side surface and the substrate. This maintains sufficient contact area for cutting while eliminating excessive friction forces.
Solution Approach 2:
The invention extracts material from the blade body to create an undercut and through-opening. This removal of material reduces the friction-generating surface area while preserving the necessary cutting contact area, directly addressing the contradiction between contact area and friction force.
2Productivity
If the cutting edge extends over the entire rear narrow side, then the cutting width is maximized, but the mechanical stability of the cutting edge decreases
Solution Approach 1:
The cutting edge is concentrated in a central area rather than distributed across the entire rear narrow side. This local concentration provides sufficient cutting width for effective operation while maintaining mechanical stability by reducing the length of the cutting edge that must be supported by the blade body.
3Adaptability or versatility
If the recess increases in depth and width counter to the cutting direction, then elastic springback of compressed material is accommodated, but the blade structure becomes more complex
Solution Approach 1:
The recess is designed to increase in depth and width counter to the cutting direction, utilizing the third dimension (depth) to accommodate elastic springback of compressed material. This dimensional approach provides adaptability without significantly increasing overall structural complexity.
