“Good day! I need to develop a drawing of a machine (device) for stitching sheets of agricultural crops. I will provide photos and video materials. Main requirements for the project: Simplicity of design: The machine should be as simple as possible to manufacture and assemble. It is preferable to use readily available materials that can be easily purchased. I understand that some parts will still need to be made individually (custom-made). There are no obstacles with shaping (bending) sheet metal and welding work. Reliability and minimal maintenance. Desired power supply is 220 V. However, I leave the final decision to you — as specialists, you know better which option will be better and easier to implement. Below, I am adding videos with examples of similar machines, as well as videos of similar devices for stitching brooms — perhaps some design solutions can be borrowed from there for our project. Have a great day, I look forward to your proposals!” https://youtube.com/shorts/rT6q4pa_VSY?si=_6iCZLlPV0YXvtUo https://youtu.be/V9nMWLxpIbA?si=xfFpMIFf6qxE0WRB

Stacking (nesting) during transportation. • Wall filling (sandwich): PIR board (30 mm) with a tolerance of ±4 mm. The groove design should compensate for this tolerance, eliminating gaps. • Wall cladding: PIR board is covered on both sides with smooth stainless steel sheets of 0.5–0.6 mm. • Assembly: Strictly with bolts (stainless steel A2/A4). Minimum number of bolted connections inside the working area for ease of cleaning and disinfection. • Feet: Height 30 mm, integrated into the lower binding contour. 2. DOOR CONSTRUCTION AND LOCKING • Sealing: Rubber seal around the entire perimeter of the reveal and a stop (false bar) for 100% elimination of gaps. • Hinges: Seat design that eliminates play (bolts serve only the function of clamping). • Locking: Mechanical latch lock “finger in hole”. • Door configuration: Doors spanning the full width and height of the facade, divided horizontally into two independent sections: upper and lower. ◦ Lower section: blind. ◦ Upper section: has a viewing window. ◦ Operating principle: The lower section opens first and, when closing, tightly presses against the upper section. • Viewing window (Product No. 1): Located in the upper section. Double-sided, with an air layer. Clamping strips for securing any transparent material (glass, plastic, or film) with a thickness of from 2 to 5 mm. 3. VENTILATION SYSTEMS (Identical for both products) • Protection: Mesh (stainless steel, wire 0.5 mm, cell 0.8 mm). Installation — through clamping frames with bolts (without drilling the mesh). • Upper exhaust (120 cooler): Cutout 200x200 mm in the roof, cooler installation through a flange with M4 thread. Under the cooler (above the mesh) — adjustable damper (shutter). • Lower intake: Two openings (left and right), raised 100 mm from the floor. Area of each — 300 cm². Both intakes have adjustable dampers (shutters). 4. PRODUCT SPECIFICATION • PRODUCT No. 1 (Vertical 600x600x1200 mm): Two-section doors (lower blind, upper with window). Equipment: lamp mounts, cable pass-throughs, mounts for IR film (on the wall), curtains for mesh suspension, strip for the shield from the end. • PRODUCT No. 2 (Horizontal cabinet 600x600x600 mm): Single-section doors without glazing. Equipment: lamp mounts, cable pass-throughs, mounts for IR film (on the wall), stainless steel guides for shelves, strip for the shield from the end. 5.

Hello! I am looking for a structural engineer or an experienced 3D designer to create a preliminary 3D model of a construction fastener (a universal flat spacer for securing cables in a groove).At this stage, I need a quality sketch concept (visualization) and basic drawing for evaluation by lawyers. The project will be further developed for the production of a mold (TPA).What needs to be designed: A flat elastic plate (fastener) with the following input data: Product dimensions: Maximum length — 62 mm, maximum width (including teeth) — 40 mm. The base thickness of the plate is about 2.5–3.0 mm. Side edges: Equipped with locking teeth inclined backward (harpoon principle). The spacing between the teeth should be uneven/variable. Central part: A through cylindrical hole with a diameter of 4.2 mm. The front side must have a conical countersink (recess) so that the screw head is hidden inside the plastic. Surrounding the hole, there should be a slight thickening (stiffening rib) to prevent the part from cracking under pressure. Top end: A flat platform for finger pressure with a fine anti-slip texture.What is required as output: A solid 3D model of the part in .STEP or .IGES format. A simple engineering drawing (sketch of the overall view) in .PDF format, considering dimensions and annotations of elements. 2-3 quality renders (isometric, side view) on a clean white background for the patent application.Important requirement: The performer must understand the specifics of plastic injection molding (TPA) and immediately incorporate basic casting drafts (0.5–1.5 degrees) into the concept so that the part is suitable for future production.Please indicate your price for this initial stage and realistic deadlines for completion. I look forward to your responses!

TECHNICAL TASK (TT)For the design and calculation of a large frame aquarium structure1. GENERAL INFORMATION AND PURPOSE Product type: Large demonstration frame-type aquarium. Purpose: Public/private interior aquarium for keeping hydrobionts. Objective: Development of design documentation (DD) for the manufacture of a metal frame, selection and calculation of the thickness of multilayer glazing (triplex), design of the base with waterproofing nodes, as well as calculation of elements for transportation by forklift.2. GEOMETRIC AND WEIGHT PARAMETERS External dimensions of the structure (L×W×H): 4000 × 1800 × 1400 mm. Height of the water column (maximum): To be structurally accepted as equal to 1300 mm (taking into account technological underfilling). Configuration: Rectangular basin with a 360° view (all 4 vertical sides — transparent glazing). Weight limitation (dry weight): The maximum weight of the fully assembled finished product (metal frame + installed glazing + bottom elements) must not exceed 3000 kg (3 tons). This is a critically important condition for ensuring logistics and the lifting capacity of rigging equipment.3. TECHNICAL REQUIREMENTS FOR CONSTRUCTIVE ELEMENTS3.1. Metal Frame (Structure) Type of construction: Spatial welded frame made of steel profile with a continuous perimeter fixation for each glass. Each of the 4 glasses is a separate panel glued into the quarter (groove) of the metal frame on 4 sides. Stiffness: The structure must have maximum stiffness against bending and twisting. The deflection of load-bearing elements under full static load must not exceed permissible values to avoid the occurrence of peak local stresses in the glass and adhesive joints. Supports: Provide supports for precise leveling and even weight distribution on the foundation/base. They may be non-adjustable.3.2. Glazing (Vertical Walls) Material: Multilayer laminated glass (triplex) based on tempered or float glass of increased transparency (type Optiwhite). Optiwhite Perform strength calculations for hydrostatic pressure. Determine the final safe formula for triplex (layer thickness and type of polymer film — PVB / SentryGlas), ensuring minimal weight with required strength. SentryGlas Calculate the depth of glass embedding in the frame and parameters of the deformation adhesive joint.3.3. Bottom of the Aquarium and Transport Nodes Base construction: Rigid frame base of the metal structure, covered with moisture-resistant sheet material (moisture-resistant plywood/composite). Bottom waterproofing: Finish coating with specialized PVC membrane ("pool foil"). Forklift clearance: The lower beam of the frame must have a structural clearance from the floor of at least 100–120 mm for unobstructed entry of forks. Pockets for the forklift: Design through guide pockets (slots) in the structure of the pallet for standard dimensions of heavy forklift forks. The pockets must pass through the entire frame for the possibility of lifting the product from either of the two long sides (4000 mm).4. CALCULATIONS AND LOADS (MANDATORY PART) The designer must provide verified calculations (including finite element method — FEM / FEA) on the following points: Hydrostatic load: Calculation of the pressure of the water column up to 1300 mm on the vertical walls and bottom (total water volume about 10,000 liters, operational weight ~10 tons). Glass strength calculation: For bending and strength considering the safety factor for frame-type aquarium constructions (not less than 3.0–4.0). Metal frame calculation: Static calculation of the filled aquarium for stiffness and deflection. Adhesive joint calculation: Selection of parameters and thickness of structural silicone/polyurethane for shear and pull-off under water pressure. Weight audit and optimization: If the total dry weight of the metal frame and calculated triplex exceeds 3 tons, measures must be taken to lighten the structure (use of high-strength steel grades with reduced profile cross-section, optimization of triplex structure, use of lightweight composites for the rough bottom).5. REQUIREMENTS FOR THE DOCUMENTATION TO BE ISSUED (DD) After the design is completed, the contractor provides: An explanatory note with calculations of the strength of the frame, glazing, and rigging nodes. Assembly drawings of the metal frame (marks KM/KMD) with a specification of metal products. Drawings of details and cutting maps of bottom elements. Detailed drawings of connection nodes: "glass — metal" "glass — damper — adhesive" "sealing of the joint PVC membrane bottom — glass — frame" "pockets for the forklift" A specification of all materials (steel grade, exact triplex formula). A 3D model of the product in a neutral format.
