Technical task: Development of design documentation (DD) for thermoboxes (insectariums)
Goal: To develop drawings for the production of two types of dismountable thermoboxes made of matte stainless steel for further export.
GENERAL DESIGN, LOGISTICS AND QUALITY REQUIREMENTS
• Operating conditions: Working temperature inside — 30°C, humidity — up to 80%. The design must be resistant to stable heating and high humidity, ensuring the tightness of joints.
• Material: Stainless steel AISI 304, surface — matte.
• Hygiene and smoothness: The inner surface must be as smooth as possible. Minimize the protrusion of nuts, ends of threads, or any fastening elements inside the structure. * Task for the designer: Propose fastening options (embedded parts, hidden connections, etc.) so that the inner walls are even.
• Quality and appearance: Professional "commercial" appearance, absence of any gaps after assembly.
• Export orientation: Assembly should be as intuitive as possible for the end user (export version).
• Walls: "Sandwich" (matte stainless steel AISI 304 + basalt wool 50 mm). The thickness of the metal for the frame and cladding must be agreed upon with me.
• Assembly: Easy to assemble, non-welded, with bolts (stainless steel A2/A4).
• Dimensions and logistics: The basic size of the filler plates is 1000 x 600 mm. The basic dimensions of the products can be adjusted only with my approval (the customer).
• Equipment and options: Legs 30 mm, lamp mounts, IR film mounts, seating places for internal racks/supports. Cable passages: Sealed, for leading wires outside. Bar for the shield.
• Protective mesh: All ventilation openings are protected by stainless mesh (cell 0.8 mm, wire 0.5 mm), fixed with pressure plates without holes in the mesh itself.
PRODUCT №1: Vertical box (2000 x 1200 x 800 mm)
• Door construction: Double-leaf across the entire width of the facade (1200 mm), trims, rubber seal. Viewing window: Double-layer on one of the leaves, height 500 mm, pressure frames (2–5 mm). Additional "vent" at the bottom of one of the leaves. Locking — mechanical latch.
• Ventilation:
◦ Lower intake: 2 openings (left and right), size 400 x 100 mm each, with dampers.
◦ Upper exhaust: Mounting place for a fan 120x120 mm on flange (M4 fastening, center distance 105 mm). The size of the opening in the "sandwich" — 200 x 200 mm. Provide for an adjustable damper.
PRODUCT №2: Small box (900 x 600 x 600 mm)
• Construction: Side doors across the entire panel, trims, rubber seal. Inside — removable/adjustable shelves.
• Ventilation:
◦ Intake: 2 openings on the sides of 400 x 100 mm each, with dampers.
◦ Top: Mounting place for a fan 120x120 mm on flange (M4 fastening, 105 mm), opening in the "sandwich" — 200 x 200 mm. Provide for an adjustable damper.
TASK FOR THE DESIGNER:
Propose optimal fastening nodes, sealed passages, and a frame design without welding. Be sure to propose design options that minimize the protrusion of any fastening elements (nuts, threads) into the internal space. The goal is a reliable, sealed structure without gaps, with a professional "commercial" appearance.
REQUIRED RESULT:
1. 3D models (STEP / SolidWorks) + interactive assembly (Autodesk Viewer).
2. Drawings of parts and nodes (connection diagrams, fastening of nets/glass/lights/IR film).
3. Unfoldings (DXF) taking into account bending coefficients.
4. Specification for stainless fasteners.
5. Proposals for design solutions, timelines, and costs.
