So magnets have issues. Who knew? They can be very powerful in close proximity but as you move them further apart their bond exponentially weakens.
And cardboard has issues. It's strong in one plane but not the other. So to create a box that functions equally in three planes takes some designing as well as lots of construction processes and therefore time. In the above picture you can see the division set inside the boxes. These are really effective in one plane but not in three. So I'm trying to find a way that they can be reinforced so that the boxes aren't 'handed.' Currently you have to 'keep the moon up' (the little crescent you can see on the lid). If I crack the structural problem on the inside, it means one less instruction for people exploring what they can and can't do in the exhibition space.
Above you can see a possible reinforcement. Hollow cubes and half cubes installed to reduce racking and improve the structural performance.
I'll be in touch with the box manufacturer to discuss this option and their suggested alternatives, as well as their thoughts on part punching or embossing holes for receiving the magnets.
Such a modification could really increase the magnets pull on each other as well as providing nice little locations for them to be fixed. Oh and it would help support the adhesive tape (that secures the magnets to the cardboard) in shear force too.
An all round improvement!
