Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In laser devices, replacing a faulty semiconductor laser beam source requires replacing the entire device due to fixed LD collimate units, leading to large-scale and cumbersome replacement work.
Innovation Solution
A light source device with a two-dimensional array of light source units, each comprising light sources and a support plate, detachably fixed to a base substrate using a fixing member, allowing for easy replacement of individual light source units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If LD collimate units are fixed to the LD holder by welding, then the structural strength and reliability are improved, but the ease of repair deteriorates because the entire laser device must be replaced when one semiconductor laser beam source fails
Solution Approach 1:
The invention divides the laser device into modular LD collimate units, each containing a semiconductor laser beam source and collimating optics. Each unit is independently replaceable, allowing faulty units to be replaced without affecting other units. The support plate with through holes enables individual unit replacement while maintaining overall device integrity.
Solution Approach 2:
The fixing member provides a dynamic, adjustable connection between LD collimate units and the support plate. The detachable fixing mechanism allows units to be easily attached and detached, transitioning from a fixed welded state to a movable replaceable state, facilitating maintenance while maintaining structural integrity during operation.
2Stability of the object's composition
If LD collimate units are fixed to the LD holder by welding, then the stability of the object's composition is improved, but the ease of operation deteriorates because replacement work becomes large-scale and cumbersome
Solution Approach 1:
The laser device is segmented into independent LD collimate units that can be individually handled and replaced. Each unit maintains its internal stability through the collimating optics and semiconductor laser beam source assembly, while the overall device composition remains stable through the support plate structure that holds all units in fixed positions.
Solution Approach 2:
The support plate acts as an intermediary between the LD collimate units and the device housing. It provides a stable mounting surface with through holes that accommodate fixing members, enabling easy unit replacement while maintaining the stability of the overall device composition during operation.
3Reliability
If the entire laser device must be replaced when one semiconductor laser beam source fails, then the reliability is maintained, but the loss of time increases due to large-scale replacement work
Solution Approach 1:
The laser device is divided into replaceable LD collimate units, allowing individual unit replacement instead of entire device replacement. This segmentation enables maintenance of overall device reliability while significantly reducing the time required for repairs by isolating and replacing only the faulty unit.
Solution Approach 2:
The invention enables selective replacement of only the faulty LD collimate unit while retaining and continuing to use the remaining functional units. This approach recovers the value of working units and avoids the time loss associated with replacing the entire device, while maintaining system reliability through the replacement of the defective component.
