項圈負責「是哪隻貓、在做什麼、跳到多高」，攝影機負責「拍下來、在家先判斷、只上傳片段」。兩者都是自有設計，零件、重量、成本都標為設計提案與粗估，打樣與詢價後更新。The collar tells us which cat, what it is doing and how high it jumped; the camera films it, decides at home and uploads only the clip. Both are our own designs. Every part, weight and cost here is a proposal or rough estimate, to be updated after prototyping and quotes.

核心機構Key mechanism
模組拆裝機制：勾一頭、壓一下Module mount: hook one end, press the other
卡座一直留在項圈上，充電時只拿下模組，不必解開項圈。磁鐵只負責把模組吸到正確位置，真正固定靠機械卡扣。The cradle never leaves the collar. To charge, only the module comes off, and the collar stays on. The magnet only guides the module into place; a mechanical latch holds it.
約 2 秒~2 s
取下Remove
一手扶著下巴前的模組Steady the module under the chin
拇指把側邊推鈕往外推約 2 mmThumb slides the side button out ~2 mm
模組右端微微翹起，捏起就拿下來The right end tips up; lift it off
約 1–1.5 小時充飽~1–1.5 h to full
充電Charge
背面朝下放上充電座Set it on the dock, back down
磁鐵自動對位，接點自動對準The magnet aligns it and the pads meet the pins
指示燈轉綠即充飽Light turns green when full
約 1 秒~1 s
裝回Clip back on
模組左端勾進卡座的固定勾Hook the left end under the fixed lip
往下壓右端，「喀」一聲輕響就扣好Press the right end down; a soft click and it's locked
方向不對放不進去，不會裝反It only fits one way round
快Fast
不解項圈、不用工具No unbuckling, no tools
取下約 2 秒、裝回約 1 秒（設計目標）~2 s off, ~1 s on (design target)
磁鐵把模組自己吸到位，不必對準The magnet pulls it into place; no aiming
方便Easy
單手就能完成One hand is enough
一頭固定勾、一頭彈簧卡榫，只有一個方向放得進去Fixed lip at one end, spring latch at the other, so it fits one way only
充電座同樣磁吸，放上去就充The dock is magnetic too; set it down and it charges
可加購第二顆模組輪流充電，貓身上永遠有一顆在記錄
An optional second module can swap in, so recording never stops
貓不抵觸Cat-friendly
全程不碰脖子、不拉扯項圈，只動下巴前那一小塊Nothing pulls on the neck; only the small piece under the chin moves
卡榫加阻尼，扣上時聲音小，不嚇到貓The latch is damped, so the click is quiet
全圓角、接縫小於 0.3 mm，不夾毛、不勾毛Fully rounded, seams under 0.3 mm: nothing pinches or snags fur
模組約 4 g、整條約 9.5 g；項圈一直戴著，貓習慣後拆裝幾乎沒感覺Module ~4 g, collar ~9.5 g; the collar stays on, so swaps go almost unnoticed
牢固可靠Secure
固定靠機械卡扣，不靠磁鐵Held by a mechanical latch, not the magnet
推鈕平貼側邊，要往特定方向推才開；抓、磨蹭、理毛都打不開The flush button only opens with a deliberate sideways push; scratching, rubbing and grooming can't open it
模組固定力目標 ≥ 3 kg，大於安全扣鬆開力（約 2 kg）：勾到東西時整條項圈先脫落，模組不會單獨掉出被誤食Module retention ≥ 3 kg, above the ~2 kg breakaway buckle: a snag releases the whole collar, and the module never comes off alone to be swallowed
會磨損的卡榫在卡座上，卡座便宜可換，模組不必換Wearing latch parts sit on the cheap, swappable cradle, not the module
待打樣驗證：推鈕力道、扣上的聲量、固定力與安全扣鬆開力的拉力測試，以及試用家庭的試戴反應。To verify at prototype: button force, click loudness, pull tests on retention vs. buckle release, and how trial cats react.

沿模組長邊切開。左端固定勾、右端彈簧卡榫卡進模組兩端的卡溝；磁鐵吸住卡座底部的鋼片做對位。Cut along the module's long side. The fixed lip (left) and the spring latch (right) engage grooves at each end; the magnet pulls toward the steel plate for alignment.轉頭裡是鏡頭、主晶片和上下馬達；底座裡是左右馬達、電源、喇叭和兩顆無線晶片。The head holds the lens, main chip and tilt motor; the base holds the pan motor, power, speaker and both radios.
零件清單與粗估成本Parts, weight & rough cost
成本以千台量、美元計，標「粗估」的項目都要向代工與供應商詢價後更新。點任一列會在 3D 裡標出該零件。Costs in USD at ~1,000 units. Every estimate must be updated with factory and supplier quotes. Tap a row to highlight the part in 3D.

依據與待確認Basis & open items
驗證期（第 1 階段）先用市售 Tapo C210：85.4 × 86.8 × 117.7 mm、182 g、左右 360°／上下 114°。它沒有藍牙接收功能，收不到項圈訊號，所以驗證時要另外放一個小型藍牙接收器。本頁畫的是打樣階段的自有版本，外型尺寸參考它。For Phase 1 validation we use an off-the-shelf Tapo C210: 85.4 × 86.8 × 117.7 mm, 182 g, 360° pan / 114° tilt. It has no Bluetooth receiver and cannot hear the collar, so validation adds a small separate receiver. This page shows our own prototype-stage camera, sized against it.
安全扣鬆開力：市售貓用安全扣常見約 2 kg（4.5 磅），一般建議落在 0.9–2.3 kg。元件價格沿用前期統合筆記；電池容量、續航都是估算，要打樣實測。Breakaway force: common cat buckles release at ~2 kg (4.5 lb); the usual guidance is 0.9–2.3 kg. Component prices carry over from the earlier synthesis notes; battery capacity and life are estimates pending prototype tests.
待確認：代工完整報價（電路板、外殼、模具、組裝）；NCC 等認證要選已認證的藍牙模組；氣壓計是否受開門與冷氣干擾；項圈與攝影機之間的室內收訊距離。Open: full factory quote (boards, housings, tooling, assembly); certification (choose pre-certified Bluetooth modules); barometer interference from doors and air-con; indoor collar-to-camera range.
