Cutter Sharpener with Pivoting Support and Modular Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cutter sharpeners are inconvenient to assemble and disassemble, and they can only form a single sharpening angle, failing to meet the needs of different sharpening angles required by users.
Innovation Solution
A cutter sharpener design featuring a base with a receiving unit containing a pivoting portion and a mounting portion with positioning sections, along with supports that can be pivotally connected to the base, allowing for easy adjustment and installation of sharpening blocks to achieve desired sharpening angles, including the use of elastic deformation portions and vacuum suction cups for stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fastening members are used to fix the sharpening component to the base, then the sharpening component is securely fixed, but the assembly and disassembly process becomes inconvenient
Solution Approach 1:
The sharpening component is divided into separate modular parts (sharpening block, support, positioning section) that can be independently assembled and disassembled. The positioning section with positioning groove and positioning head allows for tool-free assembly by simply aligning and inserting the components, eliminating the need for fastening members while maintaining secure fixation.
2Adaptability or versatility
If a single sharpening angle is provided, then the device structure is simple, but it cannot meet the needs of different sharpening angles required by users
Solution Approach 1:
The base is designed with multiple pre-defined positioning sections at different angular positions (e.g., 15°, 30°, 45°, 60°, 75°). The support with positioning head can be inserted into any of these positioning sections to achieve different sharpening angles. This allows a single device to provide multiple sharpening angle functions without requiring multiple separate devices or complex adjustment mechanisms.
3Adaptability or versatility
If multiple sharpening angle configurations are created, then different sharpening angles can be achieved, but the assembly complexity and inconvenience remain the same
Solution Approach 1:
The positioning mechanism is designed to be self-aligning and self-llocking. The positioning head automatically engages with the positioning groove when inserted, and the elastic deformation portion provides automatic tension to maintain the connection. Users can easily switch between different sharpening angles by simply removing and reinserting the support into different positioning sections without requiring tools or complex assembly procedures.

Function Achieved in This Case
Facilitates easy installation and adjustment of sharpening components to provide the desired sharpening angle, improving usability and precision by allowing multiple sharpening angles and reducing shaking during the sharpening process.
Implementation Method 1
the support further comprises an elastic deformation portion connected between the sharpening block mounting portion and the positioning section
Implementation Method 2
a vacuum suction cup mounted on the base, and a vacuum suction cup operating member operable to drive the vacuum suction cup to suck
