Bionic　innovation　design　refers　to　the　innovative　design　of　products　by　extracting　biological　information　in　nature,　which　has　great　application　prospects.　The　traditional　bionic　innovative　design　method　mostly　applies　a　small　amount　of　biological　information,　which　is　difficult　to　efficiently　retrieve　a　large　amount　of　biological　information,　and　it　is　difficult　to　produce　innovative　design　solutions　due　to　the　limitations　of　designer＇s　thinking　and　related　professional　knowledge.　To　solve　the　above　problems,　it　is　necessary　to　propose　an　integrated　innovative　design　method　based　on　a　large　number　of　biological　texts　from　website　to　assist　designers　in　making　bionic　innovative　design.　Based　on　this,　an　innovative　design　method　was　proposed　for　mapping　network　biological　texts　by　user　requirements　to　obtain　multidisciplinary　requirements　and　multi-mapping　targets　design　scheme.　Firstly,　based　on　the　neural　network　model,　the　knowledge　in　the　internet　biological　text　was　extracted　and　stored　in　the　database.　Then,　the　keywords　of　product　design　were　obtained　according　to　the　multi-disciplinary　requirement　mapping　method,　which　was　mapped　to　internet　biological　texts　by　using　the　fuzzy　mapping　method　to　obtain　engineering　design　solutions.　Finally,　the　code　was　programmed　and　the　corresponding　user　interface　was　designed　according　to　the　above　method,　and　the　feasibility　of　proposed　method　was　verified　by　taking　the　innovative　design　of　the　tubeular　type　air　heater　as　an　example.　The　results　showed　that　the　heating　effect　of　optimized　tubular　type　air　heater　was　significantly　improved,　which　indicated　that　the　proposed　method　could　solve　the　current　key　problems　of　traditional　innovative　bionic　design,　such　as　the　lack　of　biological　text　information,　the　limitation　of　designer＇s　own　thinking,　the　lack　of　integrate　interdisciplinary　expertise　and　the　unsatisfactory　generation　of　product　solution.　The　proposed　method　can　assist　the　designer　to　complete　the　bionic　innovative　design　of　products.　©　2020,　Zhejiang　University　Press.
