Solution Overview

Problem

Current fiber optic cable network systems lack a compact and secure organization solution for excess fiber optic cables and splice trays, which can lead to cable damage and operational inefficiencies.

Innovation Solution

A cable storage system comprising a chassis with pivotally engaged splice tray holders, each with a retention portion and spring mechanism, that securely holds and organizes splice trays, preventing accidental disengagement and maintaining cable integrity during handling and installation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional cable storage methods are used, then cable organization is simple, but cable security and protection from damage are insufficient

Engineering Contradiction:
Improvecable securityVSAvoidstorage structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The storage system is divided into modular components: individual retention portions for each cable, separate spring portions for each retention portion, and distinct receiving grooves. This segmentation allows each cable to be independently secured while maintaining overall system simplicity

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The spring portions automatically engage with cables when inserted into the receiving grooves, providing self-securing functionality without requiring additional fastening operations. The springs maintain constant biasing force to ensure continuous cable retention

Inventive Principle:
Principle #25Self-service

2Volume of moving object

If compact cable organization is implemented, then space efficiency increases, but access difficulty increases

Engineering Contradiction:
Improvestorage space utilizationVSAvoidcable access ease
Core Design Contradiction:
Volume of moving objectVSEase of operation

Solution Approach 1:

The retention portions are designed to be dynamically adjustable along the length of the receiving grooves, allowing cables to be inserted at various positions and secured at optimal locations. This dynamic positioning maintains compact organization while facilitating easy cable access and installation

Inventive Principle:
Principle #15Dynamics

3Reliability

If secure engagement mechanisms are added, then accidental disengagement is prevented, but device complexity increases

Engineering Contradiction:
Improveengagement securityVSAvoidretention mechanism complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The biasing force function is extracted from the main retention structure and implemented through separate spring portions. This extraction allows the retention mechanism to achieve secure engagement through simple spring-cable interaction rather than complex locking mechanisms

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

All retention portions use identical spring-based mechanisms with uniform biasing forces, creating a homogeneous retention system. This homogeneity simplifies the overall design while ensuring consistent security across all cable positions

Inventive Principle:
Principle #33Homogeneity

AI summary

A splice tray holder includes a body with a first portion, a second portion, and a front surface. A retention portion is disposed on an outer periphery of each of the first and second portions and defines a receiving groove having an inner surface that faces toward the front surface of the body. A spring portion is disposed on each of the first and second portions, wherein the spring portion is adapted to provide a biasing force in a direction from the front surface of the body toward the inner surface of the receiving groove.
