Rollable Ribbon Separator With Angled Blade for Fiber Node Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for separating fibers in rollable ribbon cables often result in damage due to aggressive adhesive bonds, as they either require delicate handling to avoid separation or cause damage when attempting to separate nodes manually.
Innovation Solution
A rollable ribbon separator tool featuring an angled blade and guiding support, allowing controlled separation of aggressively bonded fibers by positioning the blade at an acute angle to the guide surface, which slices the nodes before separating the fibers, minimizing damage to the outer coating.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If aggressive adhesive bond is used to create robust node configuration, then the rollable matrix retains its configuration during handling, but the fiber outer coating is damaged when attempting to separate nodes by hand
Solution Approach 1:
The patent introduces a separator tool as an intermediary device between the user and the aggressively bonded nodes. The tool includes a blade that mechanically cuts through the adhesive bond at the nodes, allowing separation without direct manual pulling that would damage the fiber coating. The guide surface serves as an intermediary structure that positions and supports the fiber during the separation process.
Solution Approach 2:
The patent replaces the manual mechanical separation method (pulling nodes apart by hand) with a controlled cutting mechanism. The blade systematically cuts the adhesive bond, substituting the harmful pulling force with a precise cutting action that separates nodes without damaging the fiber coating.
2Ease of operation
If weak adhesive bond is used to allow easy node separation by hand, then the installer can separate nodes without special tools, but the nodes accidentally separate through normal handling of the ribbon matrix
Solution Approach 1:
The separator tool acts as an intermediary that enables controlled separation without requiring weak bonds. The blade provides the necessary mechanical advantage to cut through strong adhesive bonds on demand, eliminating the need to compromise bond strength for ease of separation.
Solution Approach 2:
The patent changes the separation mechanism from direct manual pulling to controlled cutting. This parameter change in the separation method allows the use of strong adhesive bonds while maintaining ease of separation through the proper tool, resolving the contradiction between bond strength and separation ease.
3Stability of the object's composition
If manual node separation is attempted with strong adhesive bonds, then the node configuration remains stable during handling, but the outer coating layer is pulled away from the cladding causing unacceptable damage
Solution Approach 1:
The patent substitutes the harmful manual pulling mechanism with a controlled cutting mechanism. The blade cuts through the adhesive bond at the nodes, replacing the mechanical stress that causes coating delamination with a precise cutting action that preserves fiber integrity.
Solution Approach 2:
The separator tool with its blade and guide surface serves as an intermediary system that mediates between the strong adhesive bond and the fiber. It provides a controlled separation path that cuts the bond without transmitting damaging forces to the fiber coating.

AI summary
A rollable ribbon separator tool for separating fibers in a rollable ribbon, the rollable ribbon separator including a chassis having a length and a guide surface along the chassis length for receiving a first portion of a rollable ribbon in a flattened position, the guide surface for positioning the first portion of the rollable ribbon having a first node with selected fibers to be separated, the selected fibers being positioned flat on the guide surface. The rollable ribbon separator includes a blade securable to the chassis, the blade having a cutting edge positioned toward the guide surface at an acute angle to the guide surface. The angle of the blade cutting edge with respect to the guide surface allows the cutting edge to urge the first portion of the flattened ribbon fibers against the guide surface when the fibers are drawn through the chassis along the guide surface.
