Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optical modules face inadequate heat dissipation due to the photoelectric signal conversion circuit being located within the host, leading to inefficient thermal management.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the photoelectric signal conversion circuit is located inside the host, then the electrical connection is simplified, but the heat dissipation becomes insufficient
Solution Approach 1:
The device is divided into two separate modules: the optical module containing the photoelectric signal conversion circuit and the host containing the electrical connector. This segmentation allows the heat-generating component to be physically separated from the host, improving heat dissipation while maintaining electrical connection through the coupling structure.
Solution Approach 2:
An electrical coupling structure acts as an intermediary between the optical module and the host. This coupling structure provides both mechanical support for electrical connection and thermal isolation, allowing the photoelectric circuit to be externally located while maintaining functional connectivity.
2Temperature
If the optical module is located outside the host, then the heat dissipation is improved, but the device complexity increases
Solution Approach 1:
The electrical coupling structure serves multiple functions simultaneously: it provides mechanical support for the optical module, establishes electrical connections between components, and acts as a thermal barrier. This multi-functionality reduces the need for additional separate components, thereby limiting the increase in device complexity.
3Temperature
If the photoelectric signal conversion component is externally located, then the thermal management is improved, but the electrical connection reliability may deteriorate
Solution Approach 1:
The electrical coupling structure is pre-designed with built-in connection mechanisms that ensure reliable electrical contact before the optical module is installed. The coupling structure includes pre-positioned contact points and guiding features that facilitate proper alignment and connection, ensuring reliability from the outset.
