Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Optoelectronic modules for optical links face challenges in terms of size, assembly complexity, and tool-dependent disassembly, particularly in high-reliability environments like aerospace and telecommunications, where compactness, ease of assembly, and tool-free disassembly are critical, while also requiring robustness against temperature, shock, and humidity.
Innovation Solution
An optoelectronic module design incorporating a flexible metal blade for tool-free mounting and dismounting of optical contact elements, which transitions from an unlocked to a locked position without affecting the module's compactness, and serves as an electromagnetic shielding cover, allowing for easy integration and removal of optical contact elements without the need for specialized tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If locking systems are used to retain optical contact elements, then the reliability of connection is improved, but the size of the module increases and tool-free removal becomes difficult
Solution Approach 1:
The patent employs a flexible metallic blade instead of rigid locking systems. This blade can be bent to release the optical contact element and returns to its original position through elastic recovery, providing reliable retention while enabling tool-free removal and maintaining compact module size.
Solution Approach 2:
The locking mechanism transitions from a static rigid structure to a dynamic flexible blade that can change its state between locked and released positions. The blade's flexibility allows it to adapt during insertion and removal operations, solving the contradiction between secure retention and easy removal.
2Stability of the object's composition
If rigid locking mechanisms are used, then the stability of connection is improved, but the ease of operation for assembly and disassembly deteriorates
Solution Approach 1:
The flexible metallic blade provides stable connection during normal operation while allowing easy manipulation during assembly and disassembly. The blade's elasticity enables it to be bent by hand to release the optical contact element, then automatically returns to its locking position to maintain stable connection.
Solution Approach 2:
The flexible blade serves itself by automatically returning to its original locking position through elastic recovery after being bent to release the optical contact element. This self-resetting mechanism eliminates the need for additional tools or complex release procedures.
3Manufacturing precision
If specialized extraction tools are used, then the precision of removal is improved, but the device complexity and cost increase
Solution Approach 1:
The flexible blade enables the optical contact element to be removed by hand without requiring specialized extraction tools. The blade's design allows it to be easily bent to release the element, and it automatically returns to its locking position, eliminating the need for complex tooling.
Solution Approach 2:
The patent extracts the complex extraction tool from the system and replaces it with a simple flexible blade that can be manipulated by hand. The blade's elastic properties provide sufficient control for precise removal without requiring external specialized tools.

AI summary
The present invention relates to an optoelectronic module (M) designed to convert an electrical signal from a main electronic board into an optical signal, or vice versa. Essentially, it consists of integrating, within the optoelectronic module, a removable mounting device for an optical contact element. This element is a flexible blade whose flexibility allows it to move from an unlocked position, permitting passage of the element's body and optical ferrule, to a locking position, securing the element within the module housing once optical coupling with the module's optical ferrule has been achieved. A simple press, even a manual one, allows the element to move from a locked position to an unlocked position, permitting its removal from the module housing.
