Self-Centering Rotary Chuck for Inside Laser Engraving Clamping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional chuck-style rotary attachments for laser engraving are cumbersome and poorly suited for delicate articles, lack tilting capabilities, and struggle with clamping objects from the inside surface, often requiring additional alignment tools.
Innovation Solution
A chuck-style rotary attachment with self-centering jaws bases, a scroll wheel, and interchangeable jaws that allow for radial movement and adjustable stoppers, enabling secure clamping of delicate articles from the inside surface without additional alignment tools, and accommodating various sizes and shapes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional chuck-style rotary attachments use metal jaws to clamp articles, then articles can be securely held, but delicate articles such as glassware can be easily broken or deformed
Solution Approach 1:
The patent changes the material parameter of the clamping jaws from metal to rubber, transforming the physical properties to be gentler and more suitable for delicate articles. This material substitution maintains secure holding capability while eliminating damage risk to fragile objects like glassware.
Solution Approach 2:
The patent employs composite material construction for the rotary attachment, combining rubber clamping jaws with a structural body. This composite approach integrates the soft, non-damaging properties of rubber with the structural integrity needed for secure clamping and rotation.
2Reliability
If traditional chuck-style rotary attachments clamp articles on an outside surface, then articles can be held securely, but the maximum amount of the article's surface area is not available for engraving and the laser engraver head may collide with the jaws
Solution Approach 1:
The patent inverts the traditional clamping approach by clamping articles from the inside surface rather than the outside. This inversion allows the laser engraver head to access the maximum surface area for engraving without collision with clamping jaws, while still maintaining secure holding through the rubber jaws that conform to the article's interior geometry.
3Strength
If traditional chuck-style rotary attachments are designed for heavy metal parts, then they can handle robust work, but they become overly cumbersome and poorly suited for delicate articles
Solution Approach 1:
The patent changes the structural parameters of the rotary attachment by replacing heavy metal components with lighter materials and optimizing the geometry of the body and jaws. This reduces overall weight and complexity while maintaining sufficient strength for handling delicate articles through the rubber clamping mechanism.
4Device complexity
If traditional chuck-style rotary attachments lack tilting capabilities, then the structure remains simple, but tapered objects cannot be effectively engraved
Solution Approach 1:
The patent introduces dynamic adjustability to the rotary attachment body, enabling it to tilt and adapt to different article geometries. This dynamic capability allows the attachment to effectively hold and rotate tapered objects during laser engraving while maintaining reasonable structural simplicity through controlled degrees of freedom.
