Designing for end-user requirements

When designing the perfect part, it’s easy to lose sight of the end-user requirements. This stage is key, because if your specification is incomplete or incorrect, then the product or component may not be suitable for the desired application.

End-user requirements refer to the main functional, aesthetic and characteristics required by the intended end-user. When designing, you should consider any special characteristics or functionalities required, such as strength or the environmental tolerances needed for the part.  These could include the load the part will need to bear or the temperatures and humidity it might be exposed to. You should also consider the conditions applied during assembly e.g. exposure to paints, solvents, adhesives and even household cleaners.

While analysing the end-user requirements, remember to consider the aesthetic requirements such as surface finish and the dimensional requirements such as critical dimensions and flatness, all with realistic tolerances.

As well as the above don’t forget about the cost implications. The maximum cost for the product or component needs to be viable and within your project budget.

What’s the life expectancy of your product? Is there any need for recyclability?  While these are key factors to consider you should also view the legal requirements. This includes food contact, flammability and any dimensional standards, e.g. for fittings etc.

 When our team work with clients during the design phase, we consider these and many more aspects to ensure the delivery of a fully considered product. For more information on product and design guidelines, click the link to see our Design Guidelines section.
