Rotary Clamping Mechanism for Safe Blade Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cutter clamping devices pose difficulties in safely removing and storing sculpture blades, as direct hand contact leads to rust and potential scratches, and often requires two hands, making the process inconvenient and risky.
Innovation Solution
A rotary clamping mechanism with a cylinder and rotating connection members that allow for easy blade extraction and storage, preventing rust and finger scratches, and enabling single-handed operation by using a simple and efficient design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If direct hand contact is used to remove blades from cutter arbors, then the operation is simple and requires no additional tools, but the blades rust due to sweat and fingers are at risk of scratches
Solution Approach 1:
The patent introduces a rotary clamping mechanism as an intermediary tool between the user's hand and the blade. This mechanism includes a cylinder with rotating connection members that clamp onto the blade, allowing the user to remove blades without direct hand contact, thus preventing rust from sweat and scratches from sharp edges while maintaining ease of operation
Solution Approach 2:
The rotary clamping mechanism is designed to be self-contained and self-operating. The rotating connection members automatically clamp and release the blade through rotational motion, eliminating the need for complex manual manipulation or additional tools, thereby maintaining operational simplicity while protecting the user
2Reliability
If two hands are used to position and remove blades, then the operation is more controlled and safe, but the process becomes more complex and less convenient
Solution Approach 1:
The patent combines the functions of both hands into a single rotary clamping mechanism. The rotating connection members perform both the positioning and clamping functions that would traditionally require two hands, consolidating multiple operations into one tool that can be operated with a single hand, thus reducing operational complexity while maintaining control and safety
Solution Approach 2:
The rotary clamping mechanism is designed as a multi-functional tool that can both position and remove blades. The rotating connection members can adapt to different blade positions and orientations, providing universal functionality that replaces the need for separate positioning and removal actions, thereby simplifying the overall process while maintaining reliability
3Object-affected harmful factors
If a glove is worn to protect hands during blade removal, then scratches are prevented, but the glove may be ruined and dexterity is reduced
Solution Approach 1:
The rotary clamping mechanism serves as an intermediary tool that eliminates the need for protective gloves. By providing a dedicated tool for blade removal, the user's hands are completely isolated from contact with sharp blade edges, offering protection without the drawbacks of glove wear and reduced dexterity
Solution Approach 2:
The mechanism is designed to be self-contained and self-cleaning. The rotating connection members can be easily cleaned and maintained without requiring replacement gloves, and the tool itself protects the user without being consumed or damaged in the process, maintaining both protection and operational ease
