Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Optical connector housings can melt due to reflected light, which poses a risk of damage and safety concerns from leaked optical signals.
Innovation Solution
Incorporating a heat-resistant light-absorbing member within the housing to absorb reflected light, combined with a shutter that reflects optical signals and can open and close, preventing heat transfer to the housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a shutter with a reflecting portion is used to reflect optical signals, then optical signal reflection is achieved, but the housing may melt due to high temperature from reflected light
Solution Approach 1:
A light-absorbing member is introduced as an intermediary between the reflecting portion and the housing. This mediator absorbs the reflected optical signals and converts them to heat, preventing direct irradiation of the housing while maintaining the shutter's reflective function for optical signal containment
Solution Approach 2:
The heat-absorbing function is extracted from the housing structure and assigned to a dedicated light-absorbing member. This separates the thermal management function from the structural housing, allowing the housing to focus on mechanical protection while the specialized member handles thermal loads from reflected light
2Temperature
If a light-absorbing member is added to absorb reflected light, then housing melting is prevented, but device complexity increases
Solution Approach 1:
The light-absorbing member is designed to perform multiple functions: absorbing reflected optical signals, dissipating heat away from the housing, and potentially serving as a mounting structure for the shutter. This multi-functionality reduces the need for additional separate components, offsetting the complexity increase
Solution Approach 2:
The light-absorbing member combines several protective functions into a single integrated component, merging heat absorption, thermal management, and structural support roles that would otherwise require multiple separate elements, thereby minimizing the increase in device complexity

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Effectively suppresses housing melting and ensures eye safety by shielding optical signals, with the light-absorbing member maintaining functionality even with repeated attachment and detachment.
Implementation Method 1
a shutter having a reflecting portion that reflects an optical signal outputted from the optical transmission line
Implementation Method 2
