Development of the assembly drawing of the packaging machine

Design the components and assemblies of the extrusion line: dies, calibrators, cooling baths, cutting devices, as well as peripheral equipment, fixtures, etc. As auxiliary materials, there are photos, videos, documentation in PDF, and 3D models that can be refined according to our technical specifications. I will send the materials after the interview. From you, I need 3D models, drawings, specifications, layouts - all necessary design documentation for the contractor's manufacturing.

Develop a motor control system based on aCAN bus network, including: Selecting and specifying commercially available PLC hardware and related components. Developing the control software for operating the system from aPC and atablet (or adapting existing software to meet the system requirements). Preparing complete engineering and manufacturing documentation required for the production of the control system. A key requirement is that the maximum communication distance between the controller and the PC or tablet must beup to 100 meters. The main motor parameters, as well as the preferred/recommended hardware components, will be discussed and agreed upon during the project.

It is necessary to develop the design of an ergonomic chair/suspension for a worker who works standing for long periods during the repair of wooden pallets. The chair must be attached to the carriage of the ceiling rail system and move with the worker within the working area. The main goal is to partially relieve the load on the legs and back, while the worker's legs predominantly remain on the floor. Key requirements: designed for a user weighing approximately up to 100 kg with the necessary safety margin; adjustability of height and body support level; comfortable transition between standing, semi-sitting, and sitting positions; quick and safe release of the worker from the chair; ability to rotate around a vertical axis; the chair should not restrict the movement of arms and legs; the design should not interfere with a separate carriage with a winch for lifting pallets; provide an independent safety element or another solution against falling; parts must be available for manufacturing from steel, straps, and standard components. Expected results: Several options for the chair concept. Selection and refinement of the optimal option. 3D model of the design. Drawings of parts and assemblies with dimensions. Mounting scheme to the suspension system carriage. List of materials and ready-made components. Strength calculation of the main loaded elements. Files in STEP and PDF formats for further prototype manufacturing. I am looking for a specialist with experience in mechanical engineering, industrial design, ergonomics, or the development of suspension equipment. Preference will be given to a contractor who can not only create a visualization but also prepare a technically sound design for manufacturing and testing. Detailed dimensions of the rail system, photographs, and my developments will be provided to the selected contractor. The project is related to human safety, so the final design must undergo verification by an engineer and testing before use. Important condition regarding patents: There is a similar suspension system from the company Standing Ovation. Its product can only be used as an example of an already known solution, but its design, layout, and operating principle must not be copied. It is necessary to develop an independent technical solution that will have significant structural differences and will not replicate features protected by existing patents of Standing Ovation. I will provide the contractor with the found patent documents for review. During the development, it is necessary to: analyze the known product and propose another way to support the body; not copy the shape of the chair, frame, suspension, adjustment mechanism, and mounting scheme; prepare a brief description of the main technical differences; create a comparison table of the new solution with the Standing Ovation design; provide for the possibility of further patent verification and patenting of the own design. The contractor is expected to deliver a technically independent design; however, the final legal check for patent purity will be conducted by a separate patent specialist.

I have several ready-made samples of steam fireplaces, including a model that serves as a reference for quality, design, and functionality. The task is to develop a proprietary product under our own brand based on the analysis of existing solutions. Main tasks: complete technical analysis of existing samples; disassembly of the structure and components; determination of the operating principle of all units; preparation of technical documentation; creation of a bill of materials (BOM); selection of alternative suppliers for components; cost evaluation of production; development of the concept for our own product; preparation of a plan for transitioning from prototype to mass production.
