Fiber Splice Cassette Adapter for Heat Shrink to Crimp Conversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fiber splice cassettes require separate molds and increased inventory costs due to the inability of heat shrink splice protectors to hold mechanical crimp splice protectors, necessitating the production of two different types of cassettes.
Innovation Solution
An adapter is designed to convert a heat shrink splice holder portion of a fiber splice cassette to hold a mechanical crimp splice protector by incorporating a base portion and a holding portion with a biasing mechanism that allows an interference fit, enabling the adapter to couple with the cassette and convert it to hold mechanical crimp splice protectors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two different fiber splice cassettes are manufactured to accommodate mechanical crimp splice protectors and heat shrink splice protectors, then both types of splice protectors can be held, but manufacturing costs and inventory costs increase
Solution Approach 1:
The adapter is designed with a universal interface that can accommodate both mechanical crimp splice protectors and heat shrink splice protectors. The adapter includes a receiving portion with biasing portions that can adapt to different shapes and sizes of splice protectors, allowing a single cassette design to support multiple types of protectors through the use of interchangeable adapters rather than requiring multiple specialized cassettes
Solution Approach 2:
The adapter serves as an intermediary component between the heat shrink splice holder portion of the cassette and the mechanical crimp splice protector. This mediator allows the holder designed for heat shrink protectors to also accommodate mechanical crimp protectors by providing an interface layer that adapts between the two different connector types
2Adaptability or versatility
If three molds are required for cassette and two removable holders, then both types of splice protectors can be accommodated, but manufacturing complexity and inventory requirements increase
Solution Approach 1:
The adapter design consolidates functionality by making the adapter itself interchangeable rather than requiring different holders for different protector types. The universal cassette design with interchangeable adapters reduces the number of molds needed compared to having separate specialized holders for each protector type
Solution Approach 2:
The system is segmented into three main components: the universal cassette body, the interchangeable adapter, and the splice protector. This segmentation allows flexibility where only the adapter portion needs to be changed to accommodate different protector types, rather than replacing entire holders or cassettes
3Device complexity
If a heat shrink splice holder portion is used, then the cassette structure is simplified, but mechanical crimp splice protectors cannot be held in an interference fit
Solution Approach 1:
The adapter acts as an intermediary that bridges the gap between the heat shrink holder design and mechanical crimp protector requirements. The adapter includes biasing portions that provide the necessary interference fit capability for mechanical crimp protectors while interfacing with the existing heat shrink holder portion of the cassette
Solution Approach 2:
The adapter incorporates biasing portions that can change their physical parameters (position, shape) to accommodate different types of splice protectors. The biasing mechanism allows the adapter to adjust its dimensions and apply appropriate force for interference fit with mechanical crimp protectors, while maintaining compatibility with the heat shrink holder interface
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The adapter reduces manufacturing and inventory costs by allowing a single cassette to accommodate both types of splice protectors, enhancing flexibility and cost-effectiveness in fiber management systems.
Implementation Method 1
The biasing portion may be configured to hold a mechanical crimp splice protector in an interference fit and to include opposed wall portions that are biased toward one another to hold a fiber splice protector there between

AI summary
An adapter configured to permit a heat shrink splice holder portion of a fiber splice cassette to hold a mechanical crimp splice protector includes a base portion and a holding portion configured to extend from the base portion The holding portion may be configured to hold a first splice protector, and the base portion may be configured to include a receiving feature that may be configured to couple the adapter with a fiber splice cassette. The receiving feature may be configured to couple the adapter with a splice protector holder portion of a fiber splice cassette that is unable to hold the first splice protector so as to convert the splice protector holder portion to a splice protector holder portion that may be configured to hold the first splice protector.
