100% reusable human-sized components assemble into superstructures

The hexcentriq system consists of human sized components which assemble into a variety of rigid superstructures. Theoretically, a floor/ceiling could be erected safely by a sole person with only basic skills. No welds or fasteners are required, making the components fully reusable. Pieces are designed to interlock in a self-centering configuration. Parts can be laid out roughly and locked in place by the final 6-way wedge dropped in from above. Gravity is the glue. The geometry is such that vertical
loads transmit horizontally, further stiffening the structure where needed. Components push against eachother on 3 axes in 6 directions. The end result is a polarized weave, similar to the way carbon molecules align to make graphite. There are 4 basic frame components. These are fabricated from off the shelf 2” square metal extrusion. Selected ends are miter cut, and 3 lengths are joined in parallel with intermittent welds on opposed edges. Length of finished parts is just over 1m. The w-edged hex-cell component is injection molded in ABS plastic. This measures well under 2m wide. Other materials can be substituted for specific applications. Thermal expansion is not an issue due to the self adjusting nature of the geometry. Cranes and scaffolding are not necessary during construction. Structures erect ground up & wall to wall. The work edge is held by vertical posts jacked into place, and relocated as adjacent cells are completed. Some verticals remain as final structural members. Rules governing minimal placement are pre-engineered, reducing time/cost to get a construction approved. All effort will be made to mate the system with existing construction practices. Use of hexcentriq can be entirely unseen. The goal is to be a cost effective sustainable substitute for existing systems. Currently, when a building is condemned for safety/fashion reasons, demolished bits must go to landfill or get reprocessed/recycled at great expense. Materials are transported to remote locations. Such is not an efficient use of resources. Better to disassemble selected portions of an obsolete building and reconfigure the removed components. If the components are standardized, any unused parts can be sold for use in nearby buildings. Everyone benefits without making sacrifices.

Describe the critical need your solution addresses.

I have created models in 1/6th scale, which are performing beyond expectation. A CNC robotic welding machine has been acquired of sufficient size to fabricate the full scale metal framing components. An injection mould tool needs to be made to fabricate the full scale plastic hex components. Short run production will be done for all main components to allow any sole participant to verify a typical assembly/disassembly procedure. Destructive testing can be done to various assembled structures to determine the physical limits of the geometry. Minimal wall thickness of the components can be further optimized based on test data. The revised 1/6th scale model components will be mass produced to allow open exploration of more possible assembly configurations. I will donate tooling to everyone willing to retail produced items at a predetermined reasonable set price. Finishing pieces need to be designed which edge-blend and adapt the system for placement within more conventional constructions. I will gift the model files publically with the understanding that all potential applications can’t be foreseen. I will make every effort to promote and assist others in producing new finishers and accessories. Free collaboration will lead to the establishment of standards, making the evolved components truly universal. Immediate areas of development I wish to explore are twin layer configurations and magnetized components. Joined layers further stiffen the resulting structures. Only minor variations will be needed on the basic components to allow trestle style bracing. The current components already accommodate horizontal through-cabling for long spans or added safety factor. Magnetic polarity can further enhance the shape polarity of the frame components. Magnetic bonds are a possible substitute for cable systems, and won’t require anchoring or tensioning. Electromagnetism may be an effective way of deployment. Flipping of charges emulates a three phase power grid, thus pervasively joined with electrical service to the building.

Explain your initiative in more depth and its stage of development.

My solution puts construction back into the hands of the people. No longer need we be at the mercy of tradesmen and heavy equipment. Less fortunate nations can have equal access to pre-engineered structures. Most importantly, acceptance of reusable components will curb our impact on the environment. No added energy is expended to reprocess waste. Building materials remain on site. Built structures are ever upgradable and expandable, rapidly yielding evolved configurations which most suit local need. Best of all, this is a decidedly low tech solution. Nothing I'm proposing couldn't have been done before our Mr. Fuller. The geometry is prescribed by nature and despite our machinations, we too are natural. The emergent shape of change was inevitable. What I have presented are merely building blocks. An infinite variety of shapes and sizes are possible with the same internal structure. Multilayered designs can yield built in stairways and furniture, simply by varying the height of vertical members. I imagine organic step-walled buildings we can walk over unimpeded.

How does your strategy and approach respond creatively and comprehensively to key issues?

I have come out of retirement for the purpose of initiating action. With a growing population, we can not continue with inefficient practices in building construction. Reluctantly, I accepted a position as lead engineer of a manufacturing company. This places me strategically to produce my invention for the masses. I am well connected in both the engineering and architectural industries for needed feedback and endorsement. I will perhaps use the project as a doctorate thesis topic, thus gaining university backing. We need to reach a threshold of awareness to start revolution, and I am resigned to do what it takes to champion the cause.
