A　conceptual　design　model　is　established　by　integrating　theory　of　innovation　problem　solving　(TRIZ)　and　axiomatic　design　(AD)　to　solve　problems　for　product　innovation.　Firstly,　under　the　constraints,　TRIZ　and　AD　are　applied　to　construct　the　mapping　relation　of　function-structure,　and　then　establish　and　resolve　the　original　design　matrix.　Secondly,　judge　whether　the　original　matrix　is　coupled　or　not　with　axiomatic　design　theory,　if　not,　the　innovation　scheme　is　generated.　If　it　is　a　coupling　matrix,　then　TRIZ　toolbox　turn　the　real　problem　into　standard　engineering　parameters　to　achieve　the　purpose　of　eliminating　coupling.　Then,　feasibility　of　the　optimal　scheme　is　verified　to　make　virtual　simulation　using　ADAMS　on　seaweed　planter　manipulator.　Above　all,　the　reliability　about　the　key　parts　of　the　seaweed　planter　manipulator　is　analyzed　using　weighted　linear　response　surface　method,　and　the　size　of　the　corresponding　reliability　is　obtained,　then　the　reliability　is　verified　for　the　design　result.　©　2016　Journal　of　Mechanical　Engineering.
