The sketches show alternative joining methods we explored before finalising our chosen method. Both methods consisted of using a ‘T-joint’ that would be bolted into the substructure frame. Using this we would simply bolt the two neighbouring shading devices together through the ‘T-joint’. Method 2 was a lot weaker than Method 1 due to the greater angle the aluminium sheet is bent through.
Looking at the efficiency of our product we gathered that the ‘T-joint’ is not needed if we added tabs to the shading device fins. Doing so we were able to bend these tabs to 90 degrees as shown in the final diagram. Effectively doing the same job as the ‘T-joint’ without using excessive material.
