In　the　current　era　of　deep　integration　of　artificial　intelligence　and　various　fields　effectively　using　AI　tools　for　innovation　in　intangible　cultural　heritage　revitalization　has　become　a　major　challenge　for　contemporary　inheritors.　Therefore　it　is　valuable　to　explore　ways　to　help　intangible　cultural　heritage　inheritors　and　their　collaborating　designers.　The　goal　is　to　enable　them　to　use　AI　tools　more　effectively　for　innovative　design.　This　exploration　contributes　significantly　to　the　inheritance　and　development　of　traditional　culture.　This　paper　focuses　on　the　innovative　design　of　traditional　patterns　using　Miao　embroidery　as　the　research　subject.　It　selects　reference　graphics　including　the　classic　Butterfly　Mother　pattern　the　traditional　fish　pattern　with　clear　semantics　and　the　multi-semantic　fish　pattern　containing　human　face　images.　These　graphics　serve　as　experimental　objects.　The　goal　is　to　transform　traditional　patterns　into　modern-style　designs.　From　the　perspective　of　intangible　cultural　heritage　inheritors　prompts　are　selected　from　representation　elements　to　innovate　traditional　patterns.　The　input　prompts　are　changed　based　on　conditions　including　changes　to　the　input　prompts　with　or　without　reference　pictures　and　different　types　of　reference　pictures.　The　representation　elements　to　be　presented　are　selected　as　prompts.　Both　the　foreign　Midjourney　and　domestic　Wenxin　Yige　AI　tools　are　used.　A　single-variable　control　method　is　adopted　to　generate　flat　patterns　and　three-dimensional　products　respectively.　Using　Pierce’　s　symbol　system　from　the　three　aspects　of　object　representation　and　interpretation　the　study　analyzes　the　correlation　between　the　generated　results　and　the　prompts　as　well　as　the　correlation　between　the　presence　or　absence　of　reference　pictures.　This　analysis　helps　identify　the　characteristics　of　AI　tools　from　different　cultures　both　domestically　and　abroad　in　the　innovative　design　of　intangible　cultural　heritage.　The　following　conclusions　are　drawn　through　the　experiment.　In　the　input　of　plane　pattern　creation　in　terms　of　prompts　when　the　input　prompts　are　keywords　containing　various　representational　elements　the　patterns　generated　by　Midjourney　and　Wenxin　Yige　are　more　consistent　with　the　content　of　the　prompts.　In　the　output　of　plane　pattern　creation　Wenxin　Yige　and　Midjourney　tend　to　transform　traditional　patterns　into　abstract　and　complex　patterns.　Although　the　effect　of　direct　use　on　modern　product　packaging　is　poor　it　can　be　used　as　a　decorative　pattern.　In　the　input　of　three-dimensional　product　creation　in　designing　three-dimensional　products　although　Midjourney　and　Wenxin　Yige　lack　the　creative　ability　Midjourney　performs　better　than　Wenxin　Yige　in　three-dimensional　product　design.　In　the　creative　output　of　three-dimensional　products　the　products　generated　by　Midjourney　and　Wenxin　Yige　are　both　poor　in　three-dimensional　effects.　When　the　plane　reference　image　is　input　the　generated　results　tend　to　be　flat.　Overall　Midjourney　and　Wenxin　Yige　select　the　self-representation　element　keyword-style　prompts　in　the　input　of　plane　pattern　and　three-dimensional　product　creation　which　has　a　greater　impact　on　the　production　effect.　In　the　creative　output　when　the　plane　reference　image　is　input　the　results　generated　by　both　tend　to　be　plane　patterns　but　the　results　created　by　Midjourney　are　more　realistic　and　Wenxin　Yige　has　a　more　painterly　feel.　Three　major　conclusions　are　drawn.　First　there　are　several　methods　for　intangible　cultural　heritage　inheritors　and　their　cooperating　designers　to　use　AI　tools　for　innovative　design　of　intangible　cultural　heritage　patterns.　In　terms　of　the　selection　of　reference　images　when　using　AI　for　innovative　pattern　design　intangible　cultural　heritage　inheritors　should　carefully　select　multi-semantic　patterns　that　contain　irrelevant　associations　as　reference　images　for　foreign　AI　tools.　In　terms　of　setting　prompts　intangible　cultural　heritage　inheritors　can　communicate　with　designers　starting　from　the　type　style　shape　color　material　style　cultural　attributes　function　target　users　traditional　pattern　content　and　meaning　of　the　target　product　and　select　keywords　as　prompts　according　to　the　design　goals.　In　terms　of　the　selection　of　AI　tools　intangible　cultural　heritage　inheritors　and　auxiliary　designers　can　choose　appropriate　domestic　and　foreign　AI　tools　according　to　the　goals　of　designing　flat　or　three-dimensional　products.　Second　the　prompt　formula　for　intangible　cultural　heritage　inheritors　to　effectively　use　AI　tools　for　intangible　cultural　heritage　innovation　design　based　on　the　reference　map　of　object　elements　and　the　prompts　of　representative　elements　is　Prompt　=　A1　+　B1　+　B2　+　B3　+　B4　+　C1　+　C2　+　D1　+　D2.　Third　the　AI　design　strategy　for　intangible　cultural　heritage　inheritors　to　use　AI　tools　to　transform　traditional　pattern　innovation　into　modern　flat　patterns　and　practical　products　is　proposed　design　innovation　strategy　that　integrates　cultural　con
