Ceramic Cutter Tool Holder With Indexed Height Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cutting devices for manual ceramic-cutting machines face issues with the mounting, positioning, and fixation of the cutting tool, requiring manual adjustment and risking involuntary height changes during use.
Innovation Solution
A cutting device with a stem that moves between locking and releasing positions, featuring recesses and projections to secure the cutting tool at predetermined heights, and a spring mechanism to maintain position without manual holding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the cutting tool is mounted using a handle that acts as a lever, then the cutting tool can be tightened to the support, but the user must manually hold the cutting tool during mounting and adjustment, making the operation slow and cumbersome
Solution Approach 1:
The cutting tool mounting system employs a self-clamping mechanism where the cutting tool's own structure (front face with recesses) interacts with the stem and handle to automatically secure itself during mounting and adjustment, eliminating the need for manual holding throughout the process
Solution Approach 2:
The system pre-positions the cutting tool at predetermined heights using recesses and projections that engage before final tightening, allowing the tool to be automatically positioned correctly during mounting without requiring manual intervention to hold and adjust it
2Adaptability or versatility
If the handle is loosened to reposition the cutting tool, then the cutting tool height can be adjusted, but the cutting tool may be dropped as the pressure from the handle is released
Solution Approach 1:
The cutting tool automatically engages with the stem through its front face recesses, creating a self-retaining mechanism that holds the tool secure even when the handle is loosened for repositioning, preventing accidental drops
3Stability of the object's composition
If the cutting tool is tightened with the handle, then the cutting tool is fixed to the support, but slight involuntary rotation of the handle can occur during handling, reducing tightening force and causing involuntary height changes
Solution Approach 1:
The front face of the cutting tool incorporates specific local features (recesses) that engage with corresponding projections on the stem, creating localized mechanical interlocking that prevents rotation and maintains stable positioning independent of handle tightness
Solution Approach 2:
Instead of relying on the handle to prevent rotation through tightening force, the system inverts the approach by using the cutting tool's front face structure to actively engage with and lock onto the stem, making the positioning resistant to handle movement
4Device complexity
If the cutting tool has a smooth front face, then the mounting structure is simple, but the cutting tool can slip in an upward direction when the cutting wheel is pressed against the ceramic piece
Solution Approach 1:
The front face of the cutting tool incorporates specific local features (recesses) that engage with corresponding projections on the stem, creating localized mechanical interlocking that prevents upward slipping while maintaining overall structural simplicity
