Narrative:

Air carrier X was inbound to cvg and was handed off descending to FL240 without a crossing to sector 26. My d-side took a point out on air carrier Y climbing off of cvg to FL230. We called sector 85 to let them know we were not going to descend air carrier X and let him go over air carrier Y. Sector 83 took the hand off on air carrier Y and climbed the aircraft to FL310 and put the aircraft on sector 85's frequency. Sector 85 had to stop the aircraft at FL230 when the two aircraft got closer air carrier X advised they were responding to a TCAS alert and climbed. Separation was never lost since air carrier Y leveled off at FL230. This is the second time in a week that I have had an issue with cvg departures and cvg arrivals transitioning the rhomm SID and gavnn STAR. Recommendation; having the arrival stream cross the departure stream right where four to five different sectors could potentially become involved seems to become unnecessarily complex at times. A procedure change or airspace reconfiguration could be used.
