What this is, and what it is not
An architecture prototype built from the RFQ. It exists to make the information model discussable — not to propose a visual design, and not to represent Electromash.

What is actually being shown
Each item maps to a clause of the RFQ. The evaluation weights product-information architecture at 20 % — the highest single criterion — so that is where the depth is.
Global vs family-specific attributes
Eighteen global attributes and twenty-four family attributes, expressed as data. Filters, comparison rows and product tables all read from the same model — which is why a vector group filter never appears while motors are in the result set.
Open →§5.2Series → variant hierarchy
A catalogue is not a flat SKU list. Fifteen series expand into model variants by frame size, and every model page is derived from that, never authored by hand.
Open →§5.5Multi-parameter filtering
Filters that adapt to the current selection, a table whose columns change with the families in scope, and an empty state that routes to engineering rather than apologising.
Open →§5.6Guided selector with honest outcomes
Six conditional questions. Three possible outcomes: a shortlist with disclaimers, an engineered-to-order route, or a stop that says the requirement needs an engineer. Zone 0 and an unclassified area both stop the tool deliberately.
Open →§7Conditional RFQ workflow
Five paper questionnaires as one form. Answering 'furnace duty' reveals the through-fault question; ticking 'hazardous area' reveals five certification fields. The counter in the side rail shows the logic working.
Open →§13Replacement cross-reference
Search by the designation on the existing nameplate. Every row states how firm the equivalence is — direct, dimensional or engineering review — because those are three different commercial conversations.
Open →§7Product page without the PDF
Full technical data, definitions on hover, sibling variants, documentation and relationships. Nobody needs to download a catalogue to judge whether a machine is a candidate.
Open →§6The full proposed structure
Every section listed in §6 exists as a real page, so the prototype can be checked against the brief line by line rather than argued about in the abstract.
Open →What a prototype cannot answer
These are not gaps in the build. They are the questions that determine whether the project can be priced honestly — and none of them can be resolved without the catalogue and without Electromash engineering.
How many models are actually in the catalogue
235 pages could be 150 models or 4,000. Cost of structuring and data entry scales with that number, not with the page count. Nothing here is an estimate of the real portfolio size.
Whether the source data can be extracted automatically
A native PDF with real tables allows an automated pipeline with human validation. A Russian-language scan with table images means OCR and line-by-line checking. The two differ by a multiple, not a percentage.
What the certifications actually are
Every certification field on this prototype is a placeholder. If the schemes are GOST, EAC and TR CU rather than ATEX and IECEx, the wording of the whole site changes — and so does the liability position.
Whether replacement equivalences exist
The cross-reference table here is invented. Real equivalence data is engineering intellectual property that has to be authored by Electromash engineers. It cannot be inferred from published dimensions.
Where the product data will live
If there is an ERP or PLM system, the site can stay synchronised with production. If there is not, the website becomes the source of truth for product data — which changes the architecture, the governance and the maintenance cost.
Multilingual architecture
The language switcher in the header is inert. URL structure, fallback behaviour, translation workflow and international SEO are real decisions with real cost, and none of them are made here.
Deliberate omissions
Things left out on purpose, with the reason. A prototype that hides its limits is worse than no prototype.
- No stock photography. §5.3 asks the design to avoid generic technology imagery; schematic outlines are the honest placeholder for photographs that do not exist yet.
- No backend. Nothing is submitted, no file is uploaded, no download is served. Every such control says so at the point of interaction.
- Filter state is not in the URL. Shareable filtered links matter to engineers and would be built for production — omitted here to keep the prototype readable.
- English only. §8 names English as the principal language; the RO switch is present to mark the decision, not to work.
- Copy is illustrative and unreviewed. §5.4 requires human technical review of all English content, and none of this has had it.
