Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for aligning fiber optic connectors with detectors or emitters are time-consuming, prone to errors, and difficult to repeat consistently, as they rely on manual adjustment and frequent disconnection of the fiber optic cable, disrupting the alignment.
Innovation Solution
An apparatus comprising a stationary base and a mobile stage with orthogonally oriented adjustment screws, along with clearance slots, allows for precise alignment of the fiber optic connector with the detector or emitter without disconnecting the fiber optic cable, enabling secure positioning and easy removal of the alignment apparatus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual adjustment method is used to align fiber optic cable with transmitter or detector, then alignment can be achieved, but the process is time consuming and difficult to repeat consistently
Solution Approach 1:
The patent introduces an intermediary alignment tool with a V-block and adjustment mechanism that mediates between the fiber optic cable and the transmitter/detector. This tool provides a standardized interface and mechanical advantage, enabling precise alignment without direct manual manipulation, thereby reducing time while maintaining or improving alignment precision.
Solution Approach 2:
The patent replaces the manual mechanical adjustment method with a mechanism-driven system featuring adjustment screws, springs, and a V-block. This mechanical substitution automates the alignment process, providing consistent and repeatable results while significantly reducing the time required compared to manual observation and adjustment.
2Reliability
If manual adjustment method is used, then alignment can be achieved, but the process is prone to error
Solution Approach 1:
The alignment tool serves as a reliable intermediary device that standardizes the alignment process. By providing fixed reference surfaces, precise adjustment mechanisms, and a stable mounting system, it eliminates the variability and errors inherent in manual methods while maintaining manageable complexity through modular design.
Solution Approach 2:
The patent employs parameter changes through its adjustment mechanism, allowing precise control of the fiber optic cable position via threaded screws and spring pressure. This enables fine-tuning of alignment parameters (position, angle, pressure) to achieve reliable alignment while keeping the apparatus complexity controlled through standardized components.
3Ease of operation
If fiber optic cable is disconnected and reconnected during alignment, then adjustment can be made, but the alignment is disrupted and time is lost
Solution Approach 1:
The alignment tool is designed to perform preliminary alignment adjustments while the fiber optic cable remains connected. The V-block and adjustment mechanism allow the operator to make precise positional adjustments without disconnecting the cable, eliminating the need for repeated connection and disconnection cycles, thereby saving time and maintaining alignment continuity.
Solution Approach 2:
The patent enables continuous alignment operation by allowing adjustments to be made on the connected fiber optic cable. The mechanical adjustment system provides continuous fine-tuning capability without interruption, maintaining the useful action of signal transmission throughout the alignment process and eliminating time loss from disconnection/reconnection cycles.

AI summary
An apparatus for aligning a fiber optic connector with a detector or an emitter in a housing includes a stationary base mountable on the housing, a mobile stage movable relative to the stationary base, and spring-loaded adjustment screws on the stationary base oriented orthogonally relative to one another to adjust a position of the mobile stage in x and y directions. The stationary base and mobile stage include central openings that allow the adjustment mechanism to be positioned around the fiber optic connector. The stationary base and mobile stage also include lateral slots extending inwardly from their respective peripheral edges to their respective central openings to allow passage of a fiber optic cable when positioning or removing the apparatus.
