Innovation Solution
A method of intermittently bonding optical fibers using a pseudorandom number sequence to generate a unique bonding pattern, ensuring structural integrity, planar alignment, and flexibility, applied via a specialized printer or thermal process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If adhesive is applied continuously along the length of optical fibers, then structural integrity is maintained, but the optical fiber ribbons cannot be rolled and density is reduced
Solution Approach 1:
The continuous adhesive application is segmented into discrete intermittent bonding zones along the length of the optical fibers. This segmentation allows the ribbon to maintain structural integrity at bonded points while remaining flexible and rollable in unbonded sections, directly resolving the contradiction between structural stability and rolling capability.
2Productivity
If adhesive is applied in random patterns, then rolling is enabled, but structural integrity and planar alignment are compromised
Solution Approach 1:
Different regions of the optical fiber ribbon are assigned different bonding characteristics through specifically designed intermittent bonding patterns. The bonding zones are strategically positioned to provide structural support where needed while leaving other regions unbonded to enable rolling, achieving both structural integrity and rolling capability through localized quality variation.
3Ease of manufacture
If bonding pattern is not unique, then manufacturing is simplified, but the ability to acquire rolling capability in perpendicular direction is reduced
Solution Approach 1:
The bonding pattern incorporates asymmetric design elements that enable the ribbon to acquire rolling capability in perpendicular directions. The non-uniform distribution of bonding zones creates directional flexibility that would not be achievable with symmetric or random patterns, while still maintaining manufacturing feasibility through defined patterns.

AI summary
A method of deriving a bonding pattern for intermittently bonding optical fibers includes generating a random number, which is an integer, converting the integer into a binary series corresponding to a width-bonding pattern, applying the width-bonding pattern at a predefined position along a width of the intermittently bonded optical fiber ribbon (100) and repeating to obtain a subsequent predefined position on the intermittently bonded optical fiber ribbon (100). In particular, '0' represents the unbonded region if '1' represents the bonded region and '0' represents the bonded region if '1' represents the unbonded region.
