TRIZ　and　bionics　are　two　techniques　for　systematic　innovation　that　can　help　designers　achieve　innovative　product　solutions.　In　order　to　help　the　designer　to　determine　conflicts　happened　in　the　design　of　product,　an　adapted　TRIZ　method　is　proposed.　Bionics　is　a　new　developing　frontier　science　permeating　and　combine　biology,　mathematics　and　engineering　studies,　and　the　designer　can　attain　a　innovative　solution　by　adapting　bionics　method.　This　paper　describes　a　interactive　model　by　integrating　TRIZ　tools　with　coupling　bionics.　Firstly,　a　new　table　of　inventive　principles　based　on　biological　function　is　presented,　and　the　human–computer　interaction　query　interface　was　designed　by　MATLAB　tool.　After　design　conflicts　in　product　system　are　determined,　designer　or　group　of　ideation　chooses　from　the　bionic　template　which　is　attained　according　to　the　conflict　Matrix　2003　in　TRIZ,　The　biological　tree　model　is　built　to　analyze　biological　coupling　elements　of　the　bionic　template,　and　then　analytic　hierarchy　process　is　applied　to　figure　out　the　main　and　hypo-main　coupling　elements.　By　imitating　functions　of　the　main　and　hypo-main　coupling　elements,　different　kinds　of　bionic　coupling　models　for　product　can　be　established.　Finally,　the　designer　can　evaluate　and　judge　whether　the　innovative　solution　is　optimal　or　should　be　returned　to　design.　©　2016,　Springer-Verlag　France.
