Incentives to Repair

Sweden incentivises repair This post covers proposals in Sweden to encourage repair.  Ironically, it can still be cheaper to replace a product with new than have it repaired. I wonder if this scheme could extend to maintenance contracts for domestic appliances or even vehicles.

User Serviceable Parts Inside

All to often users are excluded from engaging with the repair and maintenance of their own products as they are advised not to do so by the manuals and labelling on products. I have even come across examples of manuals supplied with children’s bicycles that advise the owners not to undertake any maintenance or adjustments.

This proposal could apply to many different products that encase their inner workings within a concealing body. The design principle that supports this concept encourages the development of products that allow easy and safe access to the inner workings and allow users to conduct regular servicing and maintenance.

In this case, users can carefully apply oil to the roller bearings and are able to replace the drive belt once it becomes stretched of worn. Printers are an interesting subject as domestic users frequently replace ink cartridges which requires a level of access to the interior of the product.



Speculative Design Concepts

As a punctuation in this research, a small number of Speculative Design Concepts have been generated that are intended to articulate key issues identified from the work done to date.

These concepts are intentionally presented as a set of archetypes in an etherial washed out grey to emphasise the conceptual nature of each proposition.

Each example will be explored further, including creative development process, in further posts.

service prompts

Today, by chance, the service warning indicator on my VW T5 van lit up on the dashboard. This indicator tells me that I need to service the vehicle in 2000 miles. This made me consider what it is that prompts users to conduct preventative maintenance and whether the warning lights actually serve to disconnect users from the actual systems that need regular care or attention.IMG_3241

The image shown at the top of this post contains a selection of the common warning (or witness) indicators that tell the driver of a car there is an issue that needs attention. I struck me that these indicators have always raised a level of alarm when I see one light up and see me searching through the owners manual to find out exactly what the warning means. As cars have become more complex and the electronic systems they contain have become more responsive, these notifications can be delivered with much more information.

These are good examples of where technology is used to monitor the condition of certain service parts and provide an indicator to the user as to when an intervention is required. These indicators provide a convenient solution, but cannot cover all aspect s of the operation of a vehicle. There are also many examples of products where it would be inappropriate to provide so much technology simply to monitor the health of a product. There are other, simpler ways of checking the condition of many of these parts, but this requires some specialist knowledge. I suspect that most people have no idea how the vehicles that they own work, what the indicators mean or which part of the car they refer to. This seems to indicate that owners/users are far removed from the physical care of their own possessions and are unable, unwilling or simply not aware of how they can correctly maintain their own vehicles.

I started this post considering what it is that prompts someone to carry out maintenance and got distracted when thinking about the fact that the indicator lights removing the necessity to check parts of a vehicle could actually prevent people undertaking maintenance. There is more research to be done to help understand the relationship between owners and products that require some form of regular intervention.



Design for space

I came across this section of a manual published by NASA that gives guidelines for the design of spacecraft. As you  would expect, it appears that there are some demanding standards to be met when considering the design and engineering of such craft. This section of the manual is specifically focussed on Design for Maintainability and lists a number of very specific considerations and requirements to ensure that spacecraft can be maintained effectively on the Earth and in orbit.

The general principles outlined in this document look to offer some simple and sensible considerations and design requirements that could be applied elsewhere.

Often, insight derived in extreme conditions can make highlight the smallest of issues that might normally get missed under normal conditions. This manual is based on experience gained from many space flights and experiments conducted on orbiting space stations.


The photograph above shows the improvisation that saved the crew members of the ill-fated Apollo 13 mission. During an emergency return to Earth, the crew needed to replace the saturated filters from the air scrubbers used to removed CO2 from the air. The only replacements available were from a different part of the spacecraft and would not integrate with the equipment that needed to be maintained. This blog gives considerable detail of the emergency procedure that was rapidly developed on Earth to help the astronauts.

This is an example of a valuable lesson learned. The design of future craft would ensure that parts were interchangeable and I’m certain that this incident contributed to the motivation to produce the standards document mentioned above.

Publishing some form of ‘Design Guidelines’ that both encourage designers to consider maintenance as a fundamental aspect of the design process and also aid them in doing so could prove to be a useful tool.


It seems that as western society becomes more risk averse (not sure if this is true, will need to find evidence), consumers are becoming increasingly advised ‘NOT’ to maintain there own possessions. I found the following section in an owners manual for bicycles published by Raleigh America and supplied with new bicycles.

Raleigh Warnings

The warnings given are unequivocal, informing the consumer that ‘serious injury or death’ may come as a consequence of attempting to look after your bicycle! This may be genuine advice, but it may also be a means of avoiding litigation should someone injure themselves from using a badly maintained machine. It used to be common for owners to service their own vehicles, but increasingly it seems the advice given by manufacturers is to pay someone to do the work for you. This could have significant consequences in that owners may neglect maintenance due to the inconvenience or cost. This in turn could mean that some devices may become dangerous, inefficient or suffer from a reduced lifespan.

Perhaps a way forward for this work would be to consider a means of providing good advice and information to encourage consumer maintenance.

It is not at all unusual to see examples of the following labels on consumer goods. It is certain that, with electrical products, that there is some risk associated with opening the product, however there must be ways in which the design of the product can go some way to protecting the user when engaging in maintenance or servicing.


Designing products to allow ‘user servicing’ that will facilitate safe and easy maintenance may also provide a possible direction.

A concept from Toyota that shows how car designers and manufacturers use ‘Concept Vehicles’ to speculate about alternative directions for their products, but also to introduce ideas to the public. These concept cars are manifestations of design thinking and sometimes abstract concepts. In this case the most interesting aspect of this article is the statement that the materials will last for a long time if cared for. The notion of products ageing well is not new and has been explored more thoroughly in other areas of design but the idea that this work, in conjunction with pro-active caring and maintenance, supports the notion of design that encourages or makes accessible this practice of caring.
