Technical Specification
Project: Development of a tray for dates
Number of units: 2 types of boxes but one type of tray
📦 Box Types:
📦 Boxes:
1. Small box:
– Size: 180 × 180 × 30 mm (height)
– Holds: 15–16 dates
2. Large box:
– Size: 180 × 360 × 30 mm
– Holds: 30–32 dates
– Composed of two identical trays, like in the small box.
🧩 Tray requirements:
– The tray must be removable, solid (pressed form).
– Each nest (slot) adapted to dates of slightly different sizes, with the same style but with slight variability in depth or shape.
– Dimensions of the date:
• Smallest: 26 × 47 mm
• Largest (with filling, insert, and frame): 27 × 52 mm
– The depth of the tray must allow fixing the date considering the top frame and relief.
– The date must be securely fixed, even when the box is turned over.
– Material: organic mixture (biomass) — hemp, mint, starch, charcoal
– Manufacturing method: pressing using a plywood punch in an epoxy mold
– Dimensions: 180 × 180 × 25 mm (depth not exceeding 25 mm)
– Must fit tightly into the box without play
🥄 Nest shape:
– Number of dates: 15–16 in each tray
– Nest shape: organic, inspired by the SYLA logo, allowing variability
– Date sizes:
• Minimum: 26 × 47 mm
🔧 Specification:
– Tray shape: inspired by the SYLA logo (modular rounded or geometric shapes), but without sacrificing functionality.
– Material: plywood, hemp press, starch + additives (if tested).
– Pressing method: jack or manual pressure (provide hole/cone for removal).
– Drainage system: minimal ventilation/technical holes if organic press material is used.
🛠 Tongs:
– Task: select or develop compact tongs that:
• fit into both boxes;
• have a length not exceeding 175 mm;
• aesthetically match the style;
• are placed in a separate nest or integrated segment of the tray (possibly centered or on the side).
Generated options in chat may be considered, but they are schematic, i.e., do not follow AI count of dates, sizes, and no thoughtful arrangement of tongs.
One tray + one tong for small box
Two trays + one tong for large box.
What is needed at the output
✅ OUTPUT FILES:
1. 3D model of the tray (surface + nests):
Format: .STEP or .IGES (universal format for milling, CNC, CAD/CAM systems)
Alternative: .STL (if for 3D printing or visual review)
2. 3D model of the punch (if volumetric extrusion):
separate solid object with precise geometry for each nest
Format: .STEP, .IGES, or .PARASOLID (.x_t)
3. 2D contour of the tray:
4. Accompanying PDF or drawing:
with dimensions, number of nests, perspectives
Format: .PDF or .JPG with technical comments
