The third concept is extend. I will not work out this concept completely. But did do some thinking to make the concept understandable.
Extend is based on the fact that kids grow and need a new hockey stick too often. If it would not be for the sticks being too small, the kids wouldn’t need a new stick. So when the kids are growing, why not let the stick grow as well?
The hockey stick normally consists of three components. The stick, the grip and a cap. For extend the stick gets split into two parts. As can be seen in the picture below. These parts are connected to each other with a screwing system on the inside. This system lets users have the ability to lengthen their sticks whenever necessary. This lengthening is easy to do for the users themselves, only thing is that they need to remove and redo their grip for it, because the system is underneath. Therefore the stick will only be adjusted when it is really necessary.
The upper part, a standard components will not wear off and can be used during a whole field hockey carrier. More attachment can therefore be put in the upper part. This could be done with special material or personalisation.
The lower part is a convertible component. What functions the convertible component will full fill depends on the length and the needs of a kid. Options are a smaller stick, bigger stick or sensoring in the stick.
As said earlier, can the standard component cause attachment. This is one of the circular design strategies as described in the book Products that Last. When people get attached to their product they tend to keep and use it for a longer period. Also other circular design strategies are taken into account with this concept. One component is a standard model, that could be used in combination with all other components. The product is made to last, as it can grow with the kid, no new hockey sticks are needed every year. Durability will therefore increase. Also strategy design for dis- and reassembly improves. If a convertible component is not usable anymore, can the standard component still be used. Not a complete stick then has to be re-purchased but only a lower part.
This concept was primarily based on the classic long-life business model. The basis was to make a hockey stick were kids can play with for their entire kid-carrier as hockey player. During later analyses more knowledge was gained about how kids think about their sticks and what they think is important. Multiple convertible components for the lower part came out of it.
With these standard and convertible components a hybrid business model fits better with the concept. One part of the product will lasts much longer, and could be sold for a cheaper price. The other part, the convertible part is the part that will get damage due to wear age and needs to be replaced more often. The replaceable part can be more expensive than the standard component, it will be needed more often and therefore gets sold more often. This is where profit can be made.
So in what way is this product circular? Not all the materials will be thrown away too quick, the standard component lasts far longer and will save in material lost. Also will the amount of sticks needed in general be reduced, because the stick can grow together with the kid. Extra options are available to make users get more attached to the stick, like adding sensors in the convertible part, that can track for example speed and running patterns.
