Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing laser processing devices inadequately cool the control member, leading to insufficient cooling of the laser beam source unit due to secondary cooling methods that do not effectively manage the heat generated by the control member.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single air flow system is used to cool both the laser beam source and control member, then the structure is simple, but the control member cannot be cooled sufficiently leading to temperature increase
Solution Approach 1:
The patent divides the cooling system into separate air flow paths: one for the laser beam source unit and another for the control member. This segmentation allows each component to receive dedicated cooling air flow, ensuring the control member is cooled sufficiently while maintaining manageable system complexity through modular design.
Solution Approach 2:
The patent introduces a dedicated air flow path as an intermediary cooling mechanism for the control member. This separate air flow acts as a mediator that specifically addresses the cooling needs of the control member without interfering with the laser beam source cooling, resolving the temperature issue through targeted thermal management.
2Device complexity
If secondary cooling is used for the control member, then the system is simple, but the cooling efficiency is insufficient
Solution Approach 1:
The patent segments the cooling function into primary cooling for the laser beam source and separate cooling for the control member. This segmentation transforms the secondary cooling approach into a dedicated cooling system, significantly improving cooling efficiency while maintaining system simplicity through functional separation.
Solution Approach 2:
The control member is equipped with its own dedicated air flow path, allowing it to serve its own cooling needs independently rather than relying on residual cooling from the laser beam source system. This self-service approach ensures sufficient cooling efficiency for the control member.
3Device complexity
If the control member heat is not adequately managed, then the system structure remains simple, but the laser beam source unit suffers from insufficient cooling
Solution Approach 1:
The patent segments the thermal management system into distinct cooling zones for the laser beam source and control member. This segmentation prevents heat from the control member from interfering with the laser beam source cooling, thereby improving cooling reliability while keeping the overall system design simple and manageable.
Solution Approach 2:
The patent introduces a dedicated air flow path as an intermediary that isolates the control member's heat from the laser beam source cooling system. This intermediary cooling path ensures that heat generated by the control member does not compromise the cooling effectiveness of the laser beam source, enhancing system reliability.
