Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing laser processing heads lack a positioning mechanism, leading to deviations in the positional relationship between the tip end portion and the main body portion when they are separated and recoupled, affecting the processing accuracy.
Innovation Solution
A laser processing head with a first and second processing head unit coupled in a separable manner, featuring inclined surfaces with attraction members and movable pins to ensure precise positioning and prevent damage from impact forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the laser processing head is divided into separable first and second processing head units, then the impact force resistance is improved, but the positioning accuracy deteriorates
Solution Approach 1:
The laser processing head is divided into a first processing head unit and a second processing head unit that can be separated from each other. This segmentation allows the units to detach under impact force, preventing damage to the entire laser processing head while maintaining the ability to reassemble for precise positioning.
Solution Approach 2:
Positioning pins are provided in advance on the first processing head unit and corresponding positioning pin holes are provided on the second processing head unit. These positioning features are pre-configured to ensure that when the units are recoupled after separation, they automatically return to their correct relative positions without requiring complex alignment procedures.
2Ease of operation
If the processing head units are coupled in a separable manner with attraction members, then the ease of operation is improved, but the positioning accuracy deteriorates
Solution Approach 1:
The coupling mechanism combines multiple functions: attraction members (magnets) provide automatic attraction and holding force for easy coupling and decoupling, while positioning pins and positioning pin holes simultaneously ensure precise positional alignment. This merging of attraction-based coupling with mechanical positioning resolves the contradiction between ease of operation and positioning accuracy.
Solution Approach 2:
Positioning pins act as intermediary elements between the first and second processing head units. These pins fit into corresponding positioning pin holes to mediate the coupling process, ensuring that the units align precisely before the attraction members fully engage, thereby maintaining positioning accuracy while enabling easy operation.
3Strength
If inclined surfaces are provided on the processing head units, then the impact force relief is improved, but the positioning accuracy deteriorates
Solution Approach 1:
Inclined surfaces are provided on the first and second processing head units at specific angles. These asymmetric inclined surfaces allow the units to slide relative to each other during impact, relieving impact force, while the positioning pins and positioning pin holes maintain precise positioning by constraining the movement along the inclination direction.
