Too long. - Reduction Strategy (Priority: Keep Model, Category, Config, Modifier): - Remove "Cement", "Making", "Hollow" (if necessary, but "Hollow Block" is key). - Try: `QMY12-15 Mobile Hollow Block Machine with Engine & Gear – Ready to Ship` - Count: 8+1+6+1+6+1+5+1+7+1+4+1+6+1+1+1+4+1+1+1+5+1+2+1+4 = 73 chars. Still slightly over (70 limit). - Try: `QMY12-15 Mobile Block Machine with Engine & Gear – Ready to Ship` - Count: 8+1+6+1+5+1+7+1+4+1+6+1+1+1+4+1+1+1+5+1+2+1+4 = 66 chars. - "Mobile Block Machine" covers the category. "Engine & Gear" is the core config from title. "Ready to Ship" is the modifier. - Check vocabulary: "Mobile" (from category), "Block Machine" (from title/category), "Engine & Gear" (from title), "Ready to Ship" (from pool). - Is "Hollow" essential? Title says "Hollow Block". "Mobile Block Machine" is the category. - Let's try to fit "Hollow" if possible by shortening modifier? No, modifier is fixed by logic. - Can I use "In Stock" (Length 8) instead of "Ready to Ship" (Length 13)? - Layer 3 logic: Sum(28) mod 3 = 1. Pool: 0="In Stock", 1="Ready to Ship", 2="Fast Delivery". Must use "Ready to Ship". - So I must shorten the product part. - `QMY12-15 Mobile Hollow Block Machine with Engine – Ready to Ship` (Removed "& Gear"). - Count: 8+1+6+1+6+1+5+1+7+1+4+1+6+1+1+1+5+1+2+1+4 = 68 chars. - "Engine" is in title. "Gear" is in title. - Is "Engine" sufficient as core config? Yes. - Alternative: `QMY12-15 Mobile Block Machine with Engine & Gear – In Stock` -> Logic forced "Ready to Ship". - Let's re-verify the count for `QMY12-15 Mobile Block Machine with Engine & Gear – Ready to Ship`. - QMY12-15 (8) + space (1) + Mobile (6) + space (1) + Block (5) + space (1) + Machine (7) + space (1) + with (4) + space (1) + Engine (6) + space (1) + & (1) + space (1) + Gear (4) + space (1) + – (1) + space (1) + Ready (5) + space (1) + to (2) + space (1) + Ship (4). - 8+1+6+1+5+1+7+1+4+1+6+1+1+1+4+1+1+1+5+1+2+1+4 = 73. - Limit is 70. - Must cut. - `QMY12-15 Mobile Block Machine with Engine – Ready to Ship` - 8+1+6+1+5+1+7+1+4+1+6+1+1+1+5+1+2+1+4 = 64 chars. - "Engine" is a key feature of this mobile machine (diesel engine usually). - Can I keep "Hollow"? - `QMY12-15 Mobile Hollow Block Machine – Ready to Ship` (Removed config "with..."). - Structure 4 requires "with [Core Config]". - If I can't fill Structure 4 within length, "take the next fillable". - Structure 5: `[站点修饰词] [品类词] – [规格或产能限定]` - `Ready to Ship QMY12-15 Mobile Block Machine – 4-9 Inch` - Count: 13+1+8+1+6+1+5+1+7+1+1+1+4+1+4 = 61 chars. - "4-9 Inch" is in title. - This works and keeps the model and site modifier. - Let's check Structure 4 again with aggressive shortening. - `QMY12-15 Mobile Block Machine with Gear – Ready to Ship` (63 chars). - `QMY12-15 Hollow Block Machine with Engine – Ready to Ship` (65 chars). (Dropped "Mobile", but QMY implies mobile usually, though "Mobile" is category). - Structure 5 seems safer for length and information retention. - Structure 5: `[Modifier] [Category] – [Spec]` - `Ready to Ship QMY12-15 Mobile Block Machine – 4-9 Inch` - Words: Ready to Ship (Pool), QMY12-15 (Model), Mobile Block Machine (Category), 4-9 Inch (Spec from title). - Length: 13 + 1 + 8 + 1 + 6 + 1 + 5 + 1 + 7 + 3 + 1 + 1 + 1 + 4 = 53? - Ready(5)+to(2)+Ship(4) = 11 + 2 spaces = 13. - QMY12-15 = 8. - Mobile = 6. - Block = 5. - Machine = 7. - 4-9 = 3. - Inch = 4. - Spaces/Dashes: 13 + 1 + 8 + 1 + 6 + 1 + 5 + 1 + 7 + 1 + 3(-) + 1 + 3 + 1 + 4 = 59 chars. - This fits perfectly (50-70). - Does it meet "Structure 5"? Yes. - Does it meet "Layer 3"? Yes ("Ready to Ship"). - Does it meet "Vocabulary"? Yes. - Let's try to stick to Structure 4 if possible, as it's the primary calculation. - `QMY12-15 Mobile Block Machine with Engine – Ready to Ship` (64 chars). - "Engine" is a core config for mobile machines (vs electric). - This seems better than Structure 5 because "with Engine" explains the "Mobile" nature better than just "4-9 Inch". - Let's verify the text "Engine & Gear". - Title: `QMY12-15 Mobile Block Machine with Engine – Ready to Ship` - Length: 64 chars. - Fits 50-70. - Structure: [Category: QMY12-15 Mobile Block Machine] with [Config: Engine] – [Modifier: Ready to Ship]. - Note: "QMY12-15" is the model, "Mobile Block Machine" is the category. - Is "Hollow" needed? "Hollow" is in title. - `QMY12-15 Hollow Block Machine with Engine – Ready to Ship` (65 chars). - "Mobile" is the category provided in prompt. "Hollow Block Machine" is product type. - Prompt Category: "Mobile block machine". - I should prioritize "Mobile". - `QMY12-15 Mobile Block Machine with Engine – Ready to Ship` - This looks solid. - One more check on Structure 2: `[品类词] [机型号或规格] | [站点修饰词]` - `Mobile Block Machine QMY12-15 | Ready to Ship` - Length: 6+1+5+1+7+1+8+1+1+1+5+1+2+1+4 = 45 chars. Too short. - Add "Hollow": `Mobile Hollow Block Machine QMY12-15 | Ready to Ship` -> 52 chars. - Structure 4 is preferred (index 4). - Final Polish of Structure 4: - `QMY12-15 Mobile Block Machine with Engine – Ready to Ship` - Length: 64. - Content: Model (QMY12-15), Category (Mobile Block Machine), Config (Engine), Modifier (Ready to Ship). - Source title had "Engine & Gear". I dropped "Gear" to fit length. - Source title had "Cement". Dropped to fit. - Source title had "Hollow". Dropped to fit "Mobile". - "Mobile" is the classification. - Result looks good. - Wait, is "Ready to Ship" the correct selection? - Sum = 28. - Pool: In Stock (0), Ready to Ship (1), Fast Delivery (2). - 28 % 3 = 1. - Yes, "Ready to Ship". - Final String: QMY12-15 Mobile Block Machine with Engine – Ready to Ship QMY12-15 Mobile Block Machine with Engine – Ready to Ship
