Solution Overview

Problem

Existing methodologies for securing and protecting optical fiber array belts are inadequate in terms of durability, reliability, and practicality, as they fail to effectively shield against electromagnetic interference (EMI), which can cause signal degradation and impact overall system performance.

Innovation Solution

A system utilizing a conductive clamp with a U-shaped chamber and a sealant with two ends, designed to receive the optical fiber array belt, where the clamp moves along the sealant to close the ends and establish an electrical connection, with arc-shaped wings and fixed supports to prevent downward movement, ensuring effective EMI leakage prevention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If existing methodologies for securing optical fiber array belts are used, then installation is simple, but EMI protection is insufficient leading to signal degradation

Engineering Contradiction:

ImproveEMI protectionVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The EMI protection system is divided into separate functional components: a sealant member that provides the sealing function and a clamp member that provides the clamping function. This segmentation allows each component to be optimized independently while maintaining overall system simplicity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The sealant member and clamp member are designed to work together as an integrated assembly, where the clamp member secures the sealant member to the fiber optic array belt. This merging of functions provides effective EMI protection without requiring complex multi-component systems.

Inventive Principle:

Principle #5Merging (Combining)

2Reliability

If existing protection systems are used, then the structure is simple, but durability and reliability are insufficient

Engineering Contradiction:

Improveprotection reliabilityVSAvoidstructural strength

Core Design Contradiction:

ReliabilityVSStrength

Solution Approach 1:

The sealant member is constructed from multiple materials with different properties: a flexible body portion for conforming to the fiber array, conductive rubber portions for EMI shielding, and a hard cover portion for mechanical protection. This composite structure provides both durability and structural strength.

Inventive Principle:

Principle #40Composite materials

Solution Approach 2:

The flexible body portion of the sealant member is designed to absorb mechanical stresses and protect the optical fibers from damage before external forces can affect them. This pre-cushioning approach enhances both durability and protection reliability.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

3Object-affected harmful factors

If existing sealing methods are used, then installation is straightforward, but EMI leakage prevention is inadequate

Engineering Contradiction:

Core Design Contradiction:

Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The sealant member uses a flexible body portion that can be easily wrapped around and secured to the fiber optic array belt. This flexibility simplifies installation while the conductive rubber portions ensure effective EMI leakage prevention through proper sealing contact.

Inventive Principle:

Principle #30Flexible shells and thin films

Solution Approach 2:

The clamp member is designed to be movable during installation, allowing it to be positioned and secured around the sealant member and fiber array. Once installed, it provides static clamping force to maintain the seal. This dynamic design ease of installation while ensuring effective EMI protection.

AI summary

A system for sealing EMI leakage from an optical fiber array belt includes a clamp made of a first conductive material, the clamp having a substantially U-shaped chamber; and a sealant having first and second ends to receive the optical fiber array belt in between. The clamp is movable from an upper portion of the sealant to a predetermined position on the sealant, thereby closing the first and second ends of the sealant to establish an electrical connection; and wherein the sealant prevents EMI leakage from the optical fiber array belt.
