Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for stripping the outer layers from hybrid cables to expose the optical conductor are inefficient, often requiring excessive force that can damage the cable and disrupt the optical signal, due to high static and kinetic friction between the layers, which complicates installation and increases costs.
Innovation Solution
A method that reduces friction by incorporating an adhesion-reducing material characteristic in the intermediate layer, such as porosity, roughness, or geometrical form, allowing for easier stripping of the outer layers with lower energy expenditure, while maintaining the integrity of the optical conductor and reducing installation time and costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional stripping methods are used on hybrid cables, then the outer layers can be removed, but excessive force is required that damages the optical conductor and disrupts the optical signal
Solution Approach 1:
The patent introduces an intermediate layer positioned between the outer electrical conductor layer and the inner optical conductor layer. This intermediate layer acts as a mediator that reduces the friction and adhesion between these layers, allowing the outer layer to be stripped away with minimal force applied to the optical conductor, thereby preventing damage while facilitating easy stripping.
Solution Approach 2:
The intermediate layer is designed with a porous structure that reduces adhesion and friction between the outer electrical conductor layer and the inner optical conductor layer. The porosity creates a low-friction interface that enables the outer layer to slide off easily during stripping without requiring excessive force that could damage the delicate optical conductor.
2Reliability
If the cable structure is designed with thick conductors for loop resistance and grounding requirements, then electrical performance is improved, but stripping becomes more difficult requiring higher longitudinal force
Solution Approach 1:
The intermediate layer serves as a mediator between the thick outer electrical conductor layer (required for loop resistance and grounding) and the inner optical conductor layer. It reduces the adhesion and friction between these layers, allowing the thick outer layer to be stripped away easily without requiring excessive longitudinal force that would damage the optical conductor.
Solution Approach 2:
The porous structure of the intermediate layer creates a low-friction interface between the thick outer electrical conductor layer and the inner optical conductor layer. This porosity reduces adhesion forces, enabling easy stripping of the substantial outer layer while protecting the delicate optical conductor from damage during the stripping process.
3Stability of the object's composition
If adhesion between layers is high for structural stability, then cable integrity is maintained, but stripping requires excessive force and energy expenditure
Solution Approach 1:
The patent applies different adhesion characteristics to different regions of the cable structure. The intermediate layer has low adhesion to the outer electrical conductor layer to facilitate easy stripping, while maintaining adequate adhesion to the optical conductor layer for structural stability. This local differentiation of adhesion properties enables both easy stripping and cable integrity.
Solution Approach 2:
The porous intermediate layer provides a dual-function structure: it maintains structural stability by holding the cable layers together during installation, while simultaneously providing a low-friction, low-adhesion interface that enables easy stripping when needed. The porosity creates air gaps that reduce adhesion forces without compromising overall cable integrity.
