Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the laser head or laser emitting unit is replaced, then the replacement work can be performed, but manual adjustment of the optical axis and divergence angle is required due to individual differences in optical fiber cables
Solution Approach 1:
The head connector performs self-adjustment of the optical axis and divergence angle through its built-in adjustment mechanisms (optical axis adjuster with first operation unit, and divergence angle adjuster with second operation unit), eliminating the need for manual adjustment by operators during replacement work
Solution Approach 2:
The head connector is pre-configured with adjustment mechanisms that automatically align the optical axis and divergence angle when components are replaced, performing the adjustment action before the replacement is complete and eliminating subsequent manual intervention
2Extent of automation
If adjustment mechanisms are added to the head connector, then automatic alignment is achieved, but the device complexity increases
Solution Approach 1:
The optical axis adjuster and divergence angle adjuster are integrated into the head connector as unified adjustment mechanisms, combining multiple functions (optical axis alignment and divergence angle control) into a single component structure rather than separate systems
Solution Approach 2:
The head connector serves multiple functions: it connects the optical fiber cable to the laser head, holds the fiber holder, and performs both optical axis adjustment and divergence angle adjustment through its integrated mechanisms, making it a multi-functional universal component

AI summary
In the present invention, a head connector comprises an optical axis adjustment unit that adjusts the optical axis of a laser beam emitted from a tip of an optical fiber cable, and a spread angle adjustment unit that adjusts the spread angle of emitted light. The optical axis adjustment unit comprises an operation unit configured to be operable from a lateral-surface side of the head connector, and a movement unit that moves a fiber holder within a plane orthogonal to the optical axis of the emitted light in response to an operation of the operation unit. The spread angle adjustment unit comprises an operation unit provided to an insertion unit to be inserted into a laser head, and a movement unit that moves a lens in response to the operation of the operation unit.
