Create ONE single widescreen 16:9 landscape presentation-slide concept for a fictional Chinese engineering invention proposal. Premium hardware launch visual fused with precise industrial-design rendering, not a commercial pitch deck and not an existing real device. Use the attached reference image only for its dark graphite product-reveal mood, fine metal materials and exploded-depth craft; do NOT copy its smartphone, Apple logo, brand, text, components, specifications, or layout.

Exact Chinese copy to render on the slide, verbatim, and no other words:
small eyebrow: “科技创新作品答辩示例”
large product name: “桥迹”
large subtitle: “把疑点变成可复核的近距线索。”
descriptor: “桥梁表面裂缝低功耗巡检节点 · 概念设计”
small clear footer: “虚构项目 · 非赛事官方材料”

Composition: editorial title and generous calm negative space on the left; on the right, one striking but believable fictional compact sensor carriage shown very close above a rough concrete bridge surface with one fine visible surface fissure. Product is a concept, not documentary evidence: graphite housing, brushed titanium edges, a small amber inspection light, a compact lens, simple guide wheels. No dimensional markings, no numerical labels, no fabricated performance values. Show enough silhouette to understand a near-surface inspection idea, refined and manufacturable rather than sci-fi. Precise fine engineering rules and a subtle sectional contour may support the hero without adding text.

Palette: deep graphite / midnight navy, concrete gray, cool white typography, restrained amber detail. Sophisticated directional studio rim light, restrained metallic reflection, tactile concrete surface. Typography is large, elegant, highly legible Simplified Chinese with a clear hierarchy; footer remains readable. Full-bleed slide with a discreet borderless composition; no cards, no collage, no small spec panel.

Avoid extra Chinese/English text, garbled characters, pseudo-labels, interfaces, logos, watermarks, trophies, school names, patents, awards, real test claims, photoreal forensic-crack evidence, additional slides, or anything that implies official competition endorsement.
