Optical Transceiver Movable Cover for Terminal Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing optical transceivers face challenges in protecting the electrical terminals due to the increased area of the electrical plug, which can lead to accidental human contact and electrical damage, especially with two-dimensional terminal arrangements.
Innovation Solution
An optical transceiver design featuring a housing with a movable cover that covers at least part of the electrical plug when not in use, sliding mechanisms, and a pull-tab mechanism to ensure safe extraction and insertion, preventing accidental exposure of the terminals during operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the area of the electrical plug is increased to accommodate more terminals, then the functionality of the optical transceiver is improved, but the possibility of accidental human contact with terminals increases
Solution Approach 1:
A cover member is introduced as an intermediary element between the electrical plug terminals and the external environment. This cover member includes a window portion that selectively exposes only specific terminals while covering others, thereby mediating the interaction between users and the electrical plug to prevent accidental contact while maintaining necessary functionality.
Solution Approach 2:
The cover member implements local quality by creating different exposure states for different terminals. The window portion can be positioned to expose only certain terminals that need to be accessed, while other terminals remain covered. This selective exposure approach allows the system to provide different levels of access to different parts of the electrical plug based on operational requirements.
2Area of moving object
If terminals are arranged in two dimensions to reduce outer shape, then the compactness is improved, but the area occupied by the electrical plug increases
Solution Approach 1:
The terminal arrangement transitions from a one-dimensional linear layout to a two-dimensional grid layout on the electrical plug. This dimensional change allows more terminals to be packed into a compact area, reducing the overall outer shape of the optical transceiver while accommodating increased functionality requirements.
Solution Approach 2:
The cover member is designed to nest over the electrical plug, with the window portion nested within the cover structure. This nesting approach allows the cover member to effectively manage the exposed area of the electrical plug without adding significant external dimensions to the overall device.

AI summary
An optical transceiver of an embodiment comprises a housing having a rectangular solid-like shape extending in a direction pluggable into the host system, an electrical plug provided on an end of the housing closer to the host system in the direction pluggable into the host system, the electrical plug being electrically connected with the host system when the optical transceiver is plugged into the host system, and a cover provided on the end of the housing, the cover covering at least a part of the electrical plug when the optical transceiver is extracted from the host system, the cover moving with respect to the housing toward an extraction direction opposite to a direction of inserting the optical transceiver into the host system when the optical transceiver is inserted into the host system.
