Blade Sharpening Assembly Guide Portion Angle Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing knife sharpening methods struggle to maintain a precise and consistent angle, which is crucial for achieving the desired sharpness and durability of a knife edge.
Innovation Solution
A blade sharpening assembly that includes a shuttle with a guide portion and a hold portion, configured to hold a blade edge against a sharpening surface and align it at a consistent angle, allowing for precise sharpening strokes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional sharpening methods are used without guidance mechanisms, then the sharpening process is simpler and easier to operate, but the angle consistency and precision of the blade edge deteriorates
Solution Approach 1:
The patent introduces a guide portion as an intermediary element between the blade and sharpening stone. This guide portion maintains a predetermined angle relative to the sharpening stone surface, serving as a mediator that ensures consistent blade positioning and angle during sharpening, thereby resolving the contradiction between precision and complexity.
Solution Approach 2:
The hold portion is designed to automatically position and secure the blade against the guide portion and sharpening stone without requiring additional adjustment mechanisms. The blade itself serves to define the gap dimension when positioned between the hold portion and guide portion, eliminating the need for complex external positioning devices.
2Adaptability or versatility
If the hold portion is fixed in position, then the assembly structure is simpler, but the adaptability to blades of different thicknesses deteriorates
Solution Approach 1:
The hold portion is designed with dynamic adjustability, allowing its position to be changed along the shuttle to accommodate blades of different thicknesses. This dynamic positioning capability enables the gap between the hold portion and guide portion to be adjusted, providing versatility for different blade dimensions while maintaining a relatively simple overall structure.
