And i can't explain how The red jacket Uniforms stayed in service from Kirk's era to Picards younger life era, Yet all uniforms after lasted 2-3 years or a tad longer before being constantly replaced..I also can't explain why Kung FU: the legend continues lasted more than one season on Tv..ah well..life's full of Mysteries.
Actually..if i had to be tasked with explaining it for some fiction, i would say this- It's very conceivable that engineers aboard the generational Klingon ship would have the same "visions" of ideas as the ones back home, Klingon designs aren't exactly 'complex or dynamic" they are pretty stale and static, It stands to reason even light years across the galaxy, similar patterns of architecture, ship designs, and fashion, would occur. It isn't very far fetched at all, asian culture even spread out across the globe, had ancestral roots and designs for things that were very similar to one another.
