Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fusion splicing devices struggle to perform discharge tests at appropriate timings, leading to inconsistent splicing quality due to varying fusion splicing conditions, which are influenced by factors like electrode wear, environmental changes, and user-determined test schedules.
Innovation Solution
A fusion splicing device equipped with a fusion splicing control unit that automatically triggers a discharge test when predetermined conditions are met, such as first use after shipment, electrode replacement, or environmental changes, using an imaging unit to assess splicing quality and adjust conditions accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If discharge tests are performed according to user-determined schedules, then operational flexibility is maintained, but splicing quality consistency deteriorates due to varying fusion splicing conditions
Solution Approach 1:
The system automatically triggers discharge tests based on real-time detection of electrode wear degree and environmental conditions. The control unit receives feedback from sensors monitoring electrode state and environmental parameters, then autonomously determines when discharge tests are necessary, eliminating the need for user judgment while maintaining consistent splicing quality.
Solution Approach 2:
The fusion splicing device performs self-diagnosis and self-adjustment by automatically initiating discharge tests when electrode wear or environmental changes are detected. The system serves itself by monitoring its own state and triggering appropriate maintenance operations without external intervention, ensuring optimal performance while reducing operational burden.
2Reliability
If discharge tests are performed frequently to maintain splicing quality, then splicing quality consistency is improved, but productivity deteriorates due to unnecessary operations
Solution Approach 1:
The system performs preliminary detection of electrode wear degree and environmental conditions before splicing operations. By anticipating when discharge tests will be needed based on pre-monitored electrode state and environmental parameters, the system triggers tests only when necessary, avoiding both premature and delayed testing that would respectively reduce productivity or compromise quality.
Solution Approach 2:
The system dynamically adjusts the discharge test triggering threshold based on detected electrode wear degree and environmental conditions. As electrodes wear, the system adapts the criteria for triggering discharge tests, ensuring tests are performed at optimal intervals rather than fixed schedules, thereby maintaining quality while maximizing productivity.

AI summary
A fusion splicing device includes a fusion splicing unit, a fusion splicing control unit, an imaging unit, and a notification unit. The fusion splicing unit fusion-splices optical fibers by discharge between a pair of electrode rods. The fusion splicing control unit controls an operation of the fusion splicing unit and has an operation mode for performing a discharge test. The imaging unit generates image data of a fusion spliced portion of the optical fibers. The notification unit notifies various kinds of information. The discharge test is to fusion-splice the optical fibers, to check a fusion-spliced state of the optical fibers on the basis of the image data, and to adjust a fusion splicing condition to be close to an optimum condition. When a predetermined start condition is satisfied, the fusion splicing control unit causes the notification unit to notify information for requesting execution of the discharge test.
