<problem_data>
：电能转化为机械能的环节太多（电池>电机>传动>扑动），导致能量密度低，结构复杂。
</problem_data>
<solution_details>
- 新增/替换/删除了什么：删除旋转电机与所有传动机构；新增形状记忆合金丝作为直线致动器。
- 关键部件与构型：机翼主骨架为轻质碳杆，在机身两侧对称布置两根NiTi形状记忆合金丝，合金丝一端固定在机身顶部，另一端斜拉连接同侧机翼下表面的中段；机翼根部上方设置一根被动复位弹簧。
- 关键参数（至少 2 项）：SMA丝直径 0.15mm；单次通电收缩恢复力 15g。
- 核心工作机理：当脉冲电流通过SMA丝时，焦耳热使其发生奥氏体相变收缩，拉动机翼下扑；断电后，合金丝冷却变软，机翼在复位弹簧的拉力与气动升力作用下被拉回上抬位置。交替通电即可实现扑动。
- 动作时序与协同过程：左侧合金丝通电收缩（左侧下扑） -> 左侧断电冷却，右侧通电收缩（右侧下扑，左翼靠弹簧上抬） -> 交替循环。
- 适用边界与失效条件：SMA的散热速度决定了扑动频率上限，在高温环境下散热困难，会导致合金丝无法软化复位，扑动失效。
- **为什么可能有效**：实现了从电能到直线机械能的直接转化，去除了所有中间传动损耗，极致轻量化。
- **主要技术难点/风险**：SMA丝的响应频率较低（通常<10Hz），且长期交替拉伸易发生疲劳断裂。

【动画设计要求】
请结合 TRIZ 中的“最终理想解 (Ideal Final Result, IFR)”思想来设计并实现动画：
1. 聚焦理想状态：直接展示消除问题后的最终理想解状态及其运作原理，无需制作前后的状态对比。
2. 资源利用：突出展示方案是如何巧妙利用现有资源，在极少增加系统复杂度的前提下解决矛盾的。
3. 视觉引导：使用明确的视觉暗示（如高亮颜色、运动轨迹、透明度变化）引导用户关注核心创新点（即破除矛盾的关键动作）。
4. 交互性：如果适合，可增加简单的交互（如滑块、按钮）让用户手动控制动画的关键变量，深入体验理想解的动态原理。
5. 布局与尺寸：确保动画容器足够大（推荐合理设置 viewBox 并在外层容器使用 flex 居中对齐），让主体元素居中且尺寸适中，避免出现画面过小、偏离中心或被局部裁剪的问题。

这个动画实现了以下核心要素：
原理可视化
- SMA丝的颜色从冷蓝（
#2563eb）平滑过渡到热橙红（#ff4500），直观展示奥氏体相变过程 - 通电时SMA丝出现流动虚线动画模拟电流，并伴随蓝色粒子沿丝流动
- 冷却时从中段散发橙色上升热粒子，模拟散热过程
- 弹簧颜色随拉伸程度从绿变黄，线圈间距动态变化
IFR视觉引导
- 右上角半透明叉号标记"电机/齿轮/连杆"——被消除的组件
- 力箭头实时显示：橙色=SMA收缩拉力，绿色=弹簧复位力
- 底部面板直接对比传统四级传动链（删除线）与SMA两级直驱链
- 温度指示条实时反映两根SMA丝的热状态
交互控制
- 播放/暂停按钮
- 扑动频率滑块（0.3–4 Hz），体现SMA频率受限的现实约束
- 下扑角度滑块（10°–50°），可观察不同幅度下的力矩变化
- 左右SMA状态徽章实时高亮，配合中央相位文字说明当前动作阶段
积分规则：第一轮对话扣减6分，后续每轮扣4分
