Enclosure design for a building automation product

Note to all participants:
We have uploaded some pictures with the actual boards with the electronic components to gain a better understanding of size and connectors placements, please note this is work in progress and those are not images of complete boards.

We also encourage the designers to submit early proposals even if work in progress so we can provide feedback.

NOTE TO ALL DESIGNERS REGARDING THE BRIEF
I&;ve been asked to upload the specifications for the DIN rail system to be used, please make note that allowing for DIN rail mountable brackets to be attached on the back of each enclosure should be enough.

Hi NMS,
Our manufacturer allowed for some final work on the design but that work has to do with the actual dimension fit for the boards rather than the overall design, if that makes sense.

Hi ,
I am having some doubt.

1) as per your attached PDF you require enclosure for three different board. is it?
2) do you require this enclosure at concept stage or it should be directly use by your enclosure manufacture?

hi all,

Thanks for invitate and good luck for All

Hi Henrique, thank you for your interest.
We are looking for 3 separate enclosure that would fit together as in some cases the main PCB board will be a stand alone product. The clients are typically SMEs (small and medium sized enterprises), retail venues, but also hotels and hospitals to give just a few examples. The reason we care about the design and the look of the product is because in many cases it might be visible to the public.
I hope this answers your question.

I have a few questions:

1- Is it 3 enclosures that would look like they fit together(tesla example) or one enclosure for three boards?
2- Who is your main client, as in do you want the design to sell to whom(kind of person, or company)?

Based on your input we have now updated the brief. It&;s worth mentioning that final designs will be checked and adjusted by the manufacturer before going in production to ensure 100% match with the PCBs - the precise reasons we gave a range for some measurements. I also understand the need to operate within certain constrains so hopefully the updated brief provides all the information needed.

Mircea -

Thanks for the response. While the design brief you have created communicates the objective of this project very clearly, I am afraid you will need to provide more technical details if you want a finished CAD file of a product that fits correctly. This is a 3 dimensional (X,Y,Z) design problem and you have effectively only provided 2 dimensions (X, Y). The designs you receive will only be as good as the specifications that you are providing.

For the vertical height, your 70-100mm range is a good start, but 30mm is a big range considering the overall width is 100mm. Can you provide a specific height, or better yet a side view drawing of the circuit boards?

An overall envelope that this product must fit into is arguably one of the most important pieces of information. Without this information, you run the risk of a design that interferes with other objects and components surrounding the product. Can you provide a more specific envelope? This can be as simple as "can only be 100mm tall, but can be as wide as it needs to be."

Also, some more information on the external connections would be nice (ie side view drawings). It is impossible to design this enclosure around these connectors without this information.

Thank you for your comment, there is some flexibility on the vertical size, anything between 70mm-100mm should be OK. As a general rule, the enclosures should be as close as possible to the boards size. I hope this answers your questions.

I was looking through the BMS enclosure design brief that you have attached and had a few questions about the requirements:

1. There is no side view of the boards. Can you provide the vertical dimensions for the height of all the components.

2. What is the envelope this product must fit into?
