Tool Securing Interface With Protective Layers for Reliable Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tool securing devices in press brakes and similar machines are vulnerable to damage from protruding tool parts, dust, grease, and dirt, which can affect the operation of locating and communication means, leading to unreliable performance.
Innovation Solution
A protective layer is introduced to separate the locating and communication means from the receiving space, using materials with varying hardness levels to prevent damage and ensure reliable operation, and a second protective layer shields the communication elements on the tool, reducing exposure to environmental influences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the locating and communication means are placed in the receiving space for close interaction with the tool, then the positioning precision and communication reliability are improved, but the means become vulnerable to damage from protruding tool parts and contamination from dust and grease
Solution Approach 1:
A protective layer is introduced as an intermediary element between the locating/communication means and the receiving space. This layer allows the means to remain positioned close to the tool for accurate detection and communication while physically separating them from harmful factors such as protruding tool parts, dust, and grease that would otherwise cause damage or contamination
Solution Approach 2:
The protective layer is implemented as a thin film or shell structure that covers the locating and communication means. This thin protective barrier maintains the close positioning of the means relative to the tool while providing effective protection against mechanical damage and contamination from the receiving space environment
2Object-affected harmful factors
If the protective layer completely seals the locating and communication means, then protection against contamination is maximized, but communication capability may be impaired
Solution Approach 1:
The protective layer is designed with spatially varying properties: certain regions are sealed to provide maximum protection against dust and grease, while other regions are left open or transparent to allow communication signals to pass through. This local differentiation of protective quality ensures both contamination protection and maintained communication capability
