Design Joint System for tubular steel structure

Contest Brief

Target
To develop a joint system for the tubular steel structure of an already designed family of modular, reconfigurable and multi-functional furniture (see attached presentation).
We require either one joining element or a set of joining elements that will allow the tubular steel parts of each of our furniture types to be easily unassembled and reassembled in different configurations (see attached presentation).

Requirements
1. The final design of a joining element or family of joining elements for the before mentioned furniture types.
2. The joining element should allow the furniture tubular steel structure to be quickly and easily unassembled and reassembled without the use of any highly specialized tools or highly qualified personnel. The furniture types are intended for retail use and will be located on the sales floor of a department store. The unassembly and reassembly of the furniture will be performed by a salesperson with limited knowledge of conventional tools.
3. The joining element should consider that the furniture structure is made of tubular (hollowed) steel elements with a square section of 2 inches.
4. The joining element must allow for 100% stable furniture. The joining element must secure the furniture tubular steel elements firmly and securely.
5. While in its place, the joining element must allow no movement in any direction of the adjacent tubular steel elements.
6. The joining element must adapt to Mexican commercial tubular steel sections, dimensions and calibres (thicknesses).
7. The caliber (thickness) of the tubular steel square sections will be defined after the joint system solution.

Deliverables
1. Line drawings in .dwg format and rendered 3D views in .pdf format of the proposed joining element (or elements). The drawings and rendered 3D views must clearly explain how the joint element performs according to each and every one of the before mentioned Requirements.
2. The winner will be required to produce a physical prototype of the joint element made in the proposed material and 1:1 scale. The physical prototype must be delivered in Mexico City.

Restrictions
1. The proposed joining element should not be welded to the furniture tubular steel structure.

    Good day. my proposal is just rough design. i need to improve it. It is really flexible and easy to assemble. we are using this type of joints currently and they work stunning. please message me for any further information. I can provide you real photos of them and explain to you how they works. and can send already manufactured sample to you. Looking forward to hear from you. Regards.

      Dear Sir,
      I am not sure if you got my answer to your request, so it goes again in short version.
      The evaluation of the robustness of the structure is unavoidable. But it is not sensible to calculate this kind of structure in a theoretical way; it is always done by testing a prototype. Luckily, in my design is easy to do a prototype, since it does not require molds. I do suggest to go for the nearest metal sheet folder workshop (plegador in my country), to hire the manufacture of some parts, build up some structures and hit them to see if they support it. If they are strong enough, stop. Otherwise, increase the width of the metal sheet.
      I may do the prototypes for you, provided that you decide to use my solution and to pay the price, but it is kind of catch 22 situation. More reasonable is to do prototypes in your place, test until you feel satisfied and at the same time decide details like the materials and finishing. I may provide the required drawings for the parts.

      Hi,
      Thank you for your attention.
      Honestly i do not see your proposal working, since it requires making many small parts, which can cause the manufacture and assembly of the furniture very difficult.
      If you're still interested, try to design a proposal that does not have many pieces in order to have more stability.
      Thank you.

      Hola,
      Revisamos tu propuesta pero desgraciadamente creemos que no cuenta con la estabilidad suficiente.
      El uso continuo de las piezas puede desgastar rápidamente la rigidez de las piezas causando el desequilibrio de las piezas.
      Muchas gracias de cualquier forma.
      Saludos.
