Solution Overview
Problem
Existing blade sharpening methods, such as using rotation grinding stones or fixed jigs, are imprecise and lack adaptability to accommodate blades of different shapes and sizes, leading to inconsistent grinding angles and quality over time.
Innovation Solution
An adjustable blade sharpening fixture system that uses magnets for blade fixation, a tiltable table, and a pivotable linkage head with exchangeable grinding blocks to ensure precise and repeatable grinding angles, accommodating various blade shapes and sizes with minimal height difference and obstruction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a rotation grinding stone is used, then the sharpening process is simple, but the grinding angle is imprecise and inconsistent
Solution Approach 1:
The system employs a dynamically adjustable linkage head that can pivot and tilt to different angles, allowing the grinding block to be positioned at precise, variable angles relative to the blade. This replaces the static, inconsistent hand-held approach with a controlled mechanical system that maintains precise angular relationships while remaining adaptable to different blade types.
Solution Approach 2:
The patent introduces a linkage head as an intermediary mechanical element between the grinding block and the base. This linkage head with its pivot and tilt capabilities serves as a mediator that translates simple base movements into precise, controlled grinding motions at specific angles, eliminating the need for complex direct manipulation while maintaining accuracy.
2Manufacturing precision
If a fixed jig is used to hold the blade, then the grinding angle is consistent, but the system lacks adaptability for different blade shapes
Solution Approach 1:
The system replaces fixed, static jigs with a dynamic, adjustable linkage head that can pivot and tilt to accommodate different blade geometries. The linkage head's ability to change angles and positions allows the same base system to adapt to various blade shapes while maintaining consistent grinding angles through controlled mechanical motion.
Solution Approach 2:
The patent creates a universal sharpening system where the base with the adjustable linkage head can handle multiple blade types and shapes. Instead of requiring different fixed jigs for different blades, the single adjustable system provides multi-functionality by allowing angle and position adjustments to suit various blade configurations while maintaining grinding precision.
3Stability of the object's composition
If a clamp is used to fixate the blade, then the blade is securely held, but the clamp obstructs the grinding block path and may damage the blade
Solution Approach 1:
The patent replaces traditional mechanical clamps with a magnetic fixation system. Magnets embedded in the base hold the blade securely without physical contact from clamps, eliminating obstruction of the grinding block path and removing the risk of clamp-induced blade damage while maintaining stable blade positioning during the grinding process.
