For this design project I want to detail the Access model using a vending machine.
The system makes profit by charging the batteries. The vending machine charges the bicycle lamps by induction. When the bicycle lamps are charged, the quality needs to be checked. This could be done by the bicycle repair men but the user could also check this. Since this bicycle lamp is a relatively big investment for the user, it is important to have a trustworthy relationship. Only when the user only receives high quality bicycle lamps, this will be worth it. In this system I choose to for a more complex vending machine to enable this instead of having the user to this.
The vending machine needs to enable the flow: When products come into the system they need to be as soon as possible be charged, checked on quality and whether that the lamp passes the quality check or not, go directly back to the user or go to a repair/recycle facility and then back to the user. How successful the vending machine creates this flow the more profit will be generated. To enable this flow, it is important to have enough stock within the machine. This is increase by making the bicycle lamps modular: they can both be used as a red or a white lamp.
The product needs to be durable (have a long total life span): the end of life of 1 bicycle lamp should be for the user whenever the battery needs to be charged. All the parts that are vulnerable should be protected within the product against the user and the environment. That is why the product will be waterproof – integrated O-ring between the two parts of the housing. The battery will be charged through induction to avoid a vulnerable point of connection and a permanent magnet will be used to attach the product to the bicycle instead of an elastic band. In order to protect the product, it should also be challenging for the user to open the product. In that way the user cannot break anything internally and the parts (such as the battery or copper) cannot be harvested. In contradiction to that: the repair centre needs an easy disassembly. Using an industrial snap joint within the housing that consists of 2 parts, the product is easy separable with the right tool that can pop open several snap joint within the housing at one time. When the product is opened, the product needs to be easily repair and maintained. This is done by the stacked parts that are easy separable since no permanent connections need to be broken.
