Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing laser processing apparatus faces challenges in moving the condensing lens orthogonal to its optical axis due to the fixed configuration of the laser irradiation mechanism, which can lead to physical interference and limited space for movement.
Innovation Solution
A laser processing head with a housing design that allows the condensing portion to be offset and moved orthogonal to its optical axis, utilizing a compact configuration with a shorter distance between specific wall portions, enabling efficient movement and reduced space occupation, and incorporating an adjustment and circuit portion to manage heat and optimize space usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the laser irradiation mechanism is fixed in the housing with configurations arranged on the optical path, then the structural stability is improved, but the condensing lens cannot move in the direction orthogonal to its optical axis
Solution Approach 1:
The patent divides the laser irradiation mechanism into separable components: the housing containing fixed configurations, and the condensing lens that can be independently positioned. This segmentation allows the housing to remain stable while the condensing lens gains movement capability in the direction orthogonal to its optical axis, resolving the contradiction between structural stability and adaptability.
2Adaptability or versatility
If the housing is moved in the direction orthogonal to the optical axis of the condensing lens, then the condensing lens can be repositioned, but physical interference between the housing and other configurations occurs
Solution Approach 1:
The patent extracts the condensing lens from the fixed housing structure, allowing it to be repositioned independently without moving the entire housing. This extraction eliminates the physical interference problem that would occur if the housing itself were moved, while still achieving the desired repositioning capability of the condensing lens.
3Volume of moving object
If the distance between wall portions is reduced to enable compact housing, then the space occupation is reduced, but the adjustment portion and condensing portion may interfere with each other
Solution Approach 1:
The patent applies local quality by creating an asymmetric housing structure where the distance between the third and fourth wall portions is specifically reduced compared to other dimensions. The condensing portion is offset toward the fourth wall portion, and the adjustment portion is positioned on the third wall portion side, ensuring sufficient local spacing between components while achieving overall compactness.

AI summary
A laser processing head includes: a housing; an entrance portion; an adjustment portion; and a condensing portion. A distance between a third wall portion and a fourth wall portion facing each other in a second direction is shorter than a distance between a first wall portion and a second wall portion facing each other in a first direction. The housing is configured to be attached to an attachment portion of a laser processing apparatus, with at least one of the first wall portion, the second wall portion, the third wall portion, and a fifth wall portion disposed on the side of the attachment portion. The condensing portion is disposed on a sixth wall portion, and is offset toward the fourth wall portion in the second direction.
