Perhaps you should try some spelling variations:
"Computer-mixed design" » "Computer-based design"
"computer-timed design" » "computer-timed designs", "computer-time design", "computer-timer design"
"computer-aided design" » "computer-added design", "computer-aimed design"

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (("computer-aided design") OR ((("Computer-mixed design") OR ("computer-timed design")))).
• Removing quotes may allow a broader search: (( computer-aided design ) or ((( Computer-mixed design ) or ( computer-timed design )))).
• Adding a wildcard symbol may retrieve word variants: (("computer-aided design") or ((("Computer-mixed design") or ("computer-timed design"))))*.
