智慧項圈結構設計圖Smart Collar, Engineered
以上方概念圖為比例藍圖，帶寬 15 mm 為基準換算出每個部件的實際尺寸，拆成真實的零件：可拆核心、鈦框座、皮帶、安全扣、皮帶環與磁吸充電座。可以旋轉、透視、分解，點任一部件看它的做法與重量。The concept image above is the proportional blueprint. Every part is sized from it using a 15 mm strap as the reference, and split into real components: detachable core, titanium cradle, strap, breakaway clasp, keeper and magnetic dock. Rotate, see through, explode, and tap any part for how it is built and what it weighs.
概念圖做得出來嗎Can the concept be built?
換算後的尺寸與重量都在市售貓用追蹤器的範圍內：佩戴總重約 38 g，約為 4 kg 貓體重的 1%。對照 Weenect XS 追蹤器本體為 60.5 × 24.5 × 15 mm、27 g。以下四點需要在工程階段處理，但都不必改變外觀。Converted sizes and weight sit within the range of cat trackers on the market: about 38 g worn, roughly 1% of a 4 kg cat. For comparison the Weenect XS tracker body is 60.5 × 24.5 × 15 mm and 27 g. Four points need engineering attention, none of which change the look.
- 天線位置Antenna placement鈦框與核心的金屬側壁會遮蔽無線訊號。天線放在黑色玻璃下方，從正面發射，做法與智慧手錶相同。The titanium cradle and the core's metal side band shield radio signals. Put the antenna under the black glass and radiate through the front, as smartwatches do.
- 玻璃面板Glass face貓會抓、會撞家具。用化學強化玻璃或藍寶石鍍膜，邊緣做圓角倒邊，降低崩角。Cats scratch and bump furniture. Use chemically strengthened glass or a sapphire coating, with a rounded edge to avoid chipping.
- 皮帶材質Strap material真皮會吸汗、累積異味。改用防水處理皮或仿皮矽膠，外觀可維持皮革紋與車線。Untreated leather absorbs sweat and odour. Use water-resistant treated leather or leather-textured silicone, keeping the grain and stitching.
- 鈦框重量Cradle weight照圖的實心底板，鈦框約 11 g，是最重的單件。底板鏤空、壁厚控制在 1.5 mm，可降到約 8 g。With the solid floor shown, the cradle is about 11 g, the heaviest single part. A cut-out floor and 1.5 mm walls bring it to about 8 g.

從核心到整條項圈From core to collar
- 主板與電池Board and battery主板焊上晶片、加速度計與 LED，接上鋰聚合物電池。Populate the board with the radio chip, accelerometer and LED; connect the LiPo cell.
- 天線與底蓋Antenna and base天線軟板貼在玻璃下方；底蓋埋入兩顆磁鐵與充電彈簧針。Bond the antenna flex under the glass; set two magnets and the pogo pins into the base.
- 封裝核心Seal the core鈦側框、玻璃與底蓋以防水膠合，目標 IP67。Bond titanium band, glass and base with waterproof adhesive, targeting IP67.
- 鈦框座與按鍵Cradle and buttons鈦框座裝入兩側釋放按鍵、彈簧與卡榫。Fit the release buttons, springs and latches into the titanium cradle.
- 皮帶與扣具Strap and clasp皮帶兩端分別以隱藏插銷固定在框座與安全扣，再套上鈦皮帶環。Pin each strap end into the cradle and the clasp with hidden bars, then slide on the titanium keeper.
- 出廠測試Final tests安全扣脫開力、防水、跌落與充電對位測試。Clasp release force, water resistance, drop and charging alignment tests.
