Multi-Axis Sharpener Mechanism for Stable Angle Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sharpeners have limited adjustable ranges and cumbersome adjustment mechanisms, making it difficult to adapt to different cutter shapes and sharpening requirements, and often fail to maintain a fixed angle during the sharpening process.
Innovation Solution
A sharpener with a cutter holder mechanism, sharpening stick mechanism, and attitude adjusting mechanism, featuring a vertical rail, sliding body, and rotating body, allowing for multi-dimensional adjustments of the sharpening stick and cutter angle, including stepless and preset angle adjustments, to accommodate various cutter shapes and sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional threaded adjustment or pin fixation is used to adjust sharpening stick height, then angle adjustment is achieved, but the adjustment structure becomes complicated and adjustment speed decreases
Solution Approach 1:
The patent transforms the static, discrete adjustment mechanism into a dynamic continuous adjustment system. The sharpening stick can be adjusted to any angle within a range by sliding along the guide rail, eliminating the need for threaded adjustments or pin fixation at discrete positions. This dynamic adjustment capability provides both wide adaptability and structural simplicity.
Solution Approach 2:
The adjustment function is separated into independent components: the guide rail provides the adjustment path, the sharpening stick provides the cutting function, and the locking mechanism provides position fixation. This segmentation allows each component to perform its specific function efficiently without adding overall system complexity.
2Adaptability or versatility
If conventional threaded adjustment or pin fixation is used to adjust sharpening stick height, then angle adjustment is achieved, but adjustment speed decreases and user experience deteriorates
Solution Approach 1:
The continuous sliding adjustment mechanism allows rapid repositioning of the sharpening stick to any desired angle within the adjustment range, eliminating the time-consuming threaded rotation or pin insertion/removal operations. The user can quickly adapt the sharpening angle to match different cutter requirements.
Solution Approach 2:
The guide rail is pre-configured with the complete adjustment path, allowing the sharpening stick to be directly positioned at the required angle without intermediate adjustment steps. The locking mechanism is pre-positioned to secure the stick once the desired angle is reached, enabling rapid one-step adjustment.
3Ease of operation
If conventional sharpeners are used, then cutter sharpening is achieved, but fixed angle cannot be maintained during moving and sharpening process
Solution Approach 1:
The dynamic locking mechanism maintains a fixed angle during the sharpening process by securing the sharpening stick at the desired position on the guide rail. This allows the stick to be rigidly held during the actual sharpening operation, ensuring angle consistency while still permitting easy repositioning between different sharpening tasks.

AI summary
The disclosure provides a sharpener, which includes a cutter holder mechanism, a sharpening stick mechanism and an attitude adjusting mechanism. The cutter holder mechanism includes a cutter holder assembly for holding a cutter and an angle adjusting assembly configured to adjust a rotation angle of the cutter on a first plane. The attitude adjusting mechanism includes a vertical rail, a sliding body and a rotating body. The sliding body is slidably installed on the vertical rail to enable the sharpening stick mechanism to be movably arranged in a first direction, the rotating body is connected with the vertical rail to enable the sharpening stick mechanism to be rotatable in a direction parallel to a second plane, an installation part for connecting the sharpening stick mechanism is provided on the sliding body, and the grindstone is movably arranged in a second direction relative to the installation part.
