In　order　to　solve　design　contradiction　between　high　productivity　and　complexity　of　the　Device,　innovation　theory　TRIZ　has　been　introduced　into　design　process.　Using　TRIZ　theory,　a　technical　analysis　of　automatic　transplanting　machine　is　conducted.　Aiming　at　the　agency＇s　objective　function　features,　innovative　solution　is　achieved　by　system　functional　analysis　of　the　institution,　and　the　engineering　features　and　contradiction　matrix　has　been　extracted.　Through　the　contradiction　matrix　table,　40　innovative　principles,　and　39　engineering　parameters　of　the　TRIZ　innovation　principles,　combined　with　the　characteristics　of　the　automatic　transplanting　machine,　innovative　design　of　transplanting　mechanism　has　been　made.　Shown　by　the　optimization　design,　the　matrix　diffusion　agency　can　improve　the　productivity　significantly.
