About

This skill performs a structured trade study to evaluate and compare different levitation mechanisms—including magnetic, acoustic, aerodynamic, and electrostatic types—for a specific application. Use it when you need to select the most appropriate levitation approach for tasks like transport, precision measurement, or sample handling. It provides a systematic analysis to inform technical design decisions.

估浮法

以結構權衡,擇特用之最適浮法:定求、篩硬約、於軟準計分、錄決於可複權衡矩。

  • 擇新品或試之浮法
  • 較磁、聲、氣、電四法於非接取系
  • 於技閱或提中證設計
  • 求變後(如新載、環、費)重估舊浮系
  • 細設前行可行性查

  • :用述(所浮為何、何以須非接)
  • :載性(質域、材、幾、溫感)
  • :運境(溫域、氣、潔、震)
  • :功預(可用瓦)
  • :費標(原、產)
  • :精求(位準、剛、震隔)
  • :壽與維約

一:定用求

估前先立全求:

  1. 載規:質(最小至最大)、尺、材、磁性(鐵磁?導?抗磁?)、溫限(耐冷凍?熱?)、面感(接觸致污或損?)
  2. 性求:浮隙(毫米至米)、載容、位準、剛(N/m)、阻尼、動域(靜持對控動)
  3. 環約:運境之溫、氣組(空、真空、惰、液)、潔級(半導、生、工)、聲限、EMC 求
  4. 運約:可用功、殼(浮系自身大與重)、維週、壽、操員技
  5. 經約:原費、產單費、發期
## Requirements Summary
| Category | Requirement | Value | Priority |
|----------|------------|-------|----------|
| Payload mass | Range | [min - max] kg | Must have |
| Payload material | Magnetic class | [ferro/para/dia/non-magnetic] | Must have |
| Gap | Levitation height | [value] mm | Must have |
| Precision | Position accuracy | [value] um | Want |
| Temperature | Operating range | [min - max] C | Must have |
| Power | Budget | [value] W | Want |
| Cost | Unit cost target | [value] | Want |
| Environment | Cleanliness | [class or none] | Must have |
| Noise | Acoustic limit | [value] dB | Want |
| EMC | Field emission limit | [value or none] | Want |

得:求表,各標為「Must have」(硬約,過/敗)或「Want」(軟準,依刻分)。至少 5 求已定。

敗:用述過模不能設量求→訪利者或行邊析:各參定最寬可接域。無定求進行致權衡任意或偏。

二:列候浮法

列待估之浮法及其運理與本限:

  1. 被動抗磁浮:用浮物(或抗磁穩定者)於永磁場之抗磁感。無需功。僅小載(毫克至克)及強抗磁材(熱解石墨、鉍)。室溫運
  2. 主動電磁反饋:含位感與實時控之電磁。處克至百噸(maglev 列)。續需功與控系。適鐵磁與導載
  3. 超導浮:II 型超導以磁通釘被動無功浮並本穩。需冷凍(YBCO 於 77 K 用液氮,常規超導用液氦)。載限於超導大與臨流。極剛
  4. 聲駐波:超聲換能生壓節困小物。載限亞波長物(空氣 40 kHz 中常 <5 mm)。續需驅功。任材皆可無視磁電性。生可聞諧波與聲流
  5. 聲相陣:駐波浮之擴,多獨控換能。能 3D 操與重位。複與費高而活多
  6. 氣(氣軸):薄壓氣膜持物。用於精臺、氣桌、氣墊船。續需氣源。摩極低。精軸隙常 5-25 微米,氣墊船較大
  7. 氣(Coanda/Bernoulli):氣噴過曲面生低壓區以懸物。簡廉。精與剛低。用於示與工業搬
  8. 電(Coulomb):帶電極懸帶電或介物。力極低(微至毫牛)但真空中可用。用於空(引力波探、慣感)與 MEMS
  9. 電(離子阱):振電場(Paul 阱)或靜+磁(Penning 阱)困帶電粒。用於單離子至納粒。主為原子物理與質譜之實驗法
## Candidate Mechanisms
| # | Mechanism | Payload Range | Power | Temperature | Any Material? |
|---|-----------|--------------|-------|-------------|--------------|
| 1 | Passive diamagnetic | mg - g | None | Room temp | No (diamagnetic only) |
| 2 | Active EM feedback | g - 100+ t | Continuous | Room temp | No (ferro/conductive) |
| 3 | Superconducting | g - kg | Cryocooler | < 77 K | No (above SC) |
| 4 | Acoustic standing wave | ug - g | Continuous | Room temp | Yes |
| 5 | Acoustic phased array | ug - g | Continuous | Room temp | Yes |
| 6 | Air bearing | g - t | Air supply | Room temp | Yes |
| 7 | Coanda/Bernoulli | g - kg | Air supply | Room temp | Yes |
| 8 | Electrostatic Coulomb | ug - mg | Minimal | Any (vacuum ok) | No (charged/dielectric) |
| 9 | Ion trap | atoms - ug | RF power | Any (vacuum) | No (ions only) |

得:列諸物理可行浮法及其本性。含至少 4 法,跨至少 2 物理原理。

敗:某法本限不確→查文或用關析技(analyze-magnetic-levitation、design-acoustic-levitation)於篩前立之。勿依猜而篩。

三:篩硬約

去不合「Must have」之法:

  1. 各硬約為過/敗濾:諸法察每「Must have」求。單敗即去
  2. 常篩準
    • 質域:載逾本質限→去(如聲浮不能處公斤載)
    • 材容:載非磁而法需磁→去(如鐵磁物不能被動抗磁浮)
    • :環不可冷凍→去超導浮
    • 真空/氣:真空境→去氣法。EMC 禁磁場→去磁法
    • :氣軸需近平面(準接)。須真非接→去之
  3. 去時注因:錄去因以便求變時重估
## Screening Results
| # | Mechanism | Pass/Fail | Eliminating Constraint | Reason |
|---|-----------|-----------|----------------------|--------|
| 1 | Passive diamagnetic | [P/F] | [constraint or N/A] | [reason] |
| 2 | Active EM feedback | [P/F] | [constraint or N/A] | [reason] |
| ... | ... | ... | ... | ... |

得:減候列,各過諸硬約。至少一存;宜 2-4 留待評分。

敗:無法過諸硬約→求相悖。鬆最不要「Must have」(改為「Want」)並重篩。須鬆多求→或須混法(如磁主氣穩)。

四:計分於軟準

以權矩排存法:

  1. 定準與權:各「Want」改為準。依相重賦權(如 1-5 或和為 100%)。常準:
    • (原與單)
    • :件數、控電、對準要
    • :位準、剛、震隔
    • 功耗:運瓦、待瓦
    • :能處載域或大量產
    • 可控:動調隙、位、剛之易
    • :技備度、商件可用
    • :聲、電、震
  2. 各法計分:各法於各準以一致刻(如 1=劣、3=足、4=善、5=優)。基量數於 1-3 步而勿主觀
  3. 算權分:各法各準分乘權後和。最高者為首候
  4. 敏析:前 2-3 權變 ±20%,察排變否。若排感於權擇→記並示替於決者
## Scoring Matrix
| Criterion | Weight | Mech A | Mech B | Mech C |
|-----------|--------|--------|--------|--------|
| Cost | [w1] | [s1A] | [s1B] | [s1C] |
| Complexity | [w2] | [s2A] | [s2B] | [s2C] |
| Precision | [w3] | [s3A] | [s3B] | [s3C] |
| Power | [w4] | [s4A] | [s4B] | [s4C] |
| Scalability | [w5] | [s5A] | [s5B] | [s5C] |
| Controllability | [w6] | [s6A] | [s6B] | [s6C] |
| Maturity | [w7] | [s7A] | [s7B] | [s7C] |
| **Weighted Total** | | **[T_A]** | **[T_B]** | **[T_C]** |
| **Rank** | | [rank] | [rank] | [rank] |

得:全分矩,諸準有權,諸法有分。排明,首候識。敏析證排韌(或記何脆)。

敗:兩法分差 <10%→紙上難定。建兩法皆原而依實選,或識破結之鑒試。

五:錄建與權衡

出末權衡報:

  1. :述建法,一段理引分與關鑒準
  2. :識次名並釋何況下為首選(此為退策)
  3. 已去法:簡列被去法與去約以全
  4. 險與緩:建法之前 3 技險與建緩
  5. 下步:定須何細設(引適析技:磁用 analyze-magnetic-levitation、聲用 design-acoustic-levitation 等)
## Trade Study Summary

### Recommendation
**[Mechanism name]** is recommended for [application] because [2-3 sentence justification
referencing the key scoring advantages].

### Runner-Up
**[Mechanism name]** would be preferred if [condition changes, e.g., "cryogenics become
available" or "payload mass decreases below X grams"].

### Eliminated Mechanisms
- [Mechanism]: eliminated by [constraint]
- [Mechanism]: eliminated by [constraint]

### Risks
| Risk | Impact | Likelihood | Mitigation |
|------|--------|-----------|------------|
| [Risk 1] | [H/M/L] | [H/M/L] | [action] |
| [Risk 2] | [H/M/L] | [H/M/L] | [action] |
| [Risk 3] | [H/M/L] | [H/M/L] | [action] |

### Next Steps
1. [Detailed analysis using specific skill]
2. [Prototype or simulation task]
3. [Experimental validation milestone]

得:自足之權衡文,他工可閱、質、行。建可追至求與分,非未述偏好。

敗:建不能僅依分證(如首法有準未捕之致命)→回一步加缺求。勿於不錄因時覆分。

  • 用求以量值與級分定
  • 至少 4 法跨 2+ 物理原理已列
  • 硬約篩一致施並錄去
  • 至少 2 法存供有意較
  • 準有明權且諸分有理
  • 前 2-3 權因行敏析
  • 建含可追至分矩之理
  • 次與退策條件已錄
  • 險與緩於建法已識
  • 權衡足全使獨閱者可驗

  • 權衡前定錨於偏法:自結起反推求或權以支之。治:定求與權於估任法前。若已知欲擇之法→權衡為驗非選——誠告之
  • 漏生域:磁背景工忽聲法反之亦然。初列必含四大族各至少一(磁、聲、氣、電),縱多將被篩去
  • 硬軟約混:以偏為硬約致可行法早去。唯真不可談之求(安、物理限、規)為硬約。餘皆計分
  • 默平權:諸準同權為決——意諸準同重。利者宜明定先級。若拒→用配對較(AHP)取隱權
  • 忽系交互:浮法不孤存。聲浮生噪或損鄰器。主磁浮發時變場或違 EMC。超導浮需冷凍基。於系境中估
  • 無不確之單點分:於費計「4」意假精。可則分為域(如「3-5」)並傳不確至末排。兩法分域重→排非定

  • analyze-magnetic-levitation — 磁為建或候時之細析
  • design-acoustic-levitation — 擇聲時之細設
  • analyze-magnetic-field — 算磁估所需之磁場廓
  • argumentation — 適權衡之結構推與決證技
