Predictika · Window hardware configuration: hinge side, sash size and sash weight

An AI sales agent's Roto NX tilt&turn hinge-side order, checked before it goes out

An AI sales agent prepares a hardware order for a window fabricator: a Roto NX hinge side, frame material, sash size, sash weight and the options that carry heavy sashes. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the public technical limits and returns a verdict, every reason and the figures it computed.

Scope: Roto NX | C and NX | Power Hinge orders: frame material, operation, sash rebate size, sash weight, load-transfer options, comfort ventilation and tilt security. See everything this validator covers

This validator models orders for two hinge sides of one hardware family, Roto NX, not just the scenarios shown below.

  • NX | C concealed hinge side — timber and PVC frames; sash rebate width 340 to 1750 mm (the minimum depends on the profile) and height 285 to 3000 mm; 120 kg standard, 100 kg with a threshold, 150 kg (PVC) or 180 kg (timber) with load transfer and turn restrictor, with a fastening plate above 150 kg.
  • NX | Power Hinge — timber and timber/aluminium frames; sash rebate width up to 1600 mm and height up to 3000 mm; up to 200 kg for Tilt&Turn and 300 kg for Turn-Only, with a central hinge from 200 kg that goes to a person for confirmation.
  • Variants and checks — comfort ventilation (tilt-only up to 80 kg, turn-only up to 100 kg, 30 mm rebate depth recommended), RC 2 in the tilt position needing TiltSafe components, and the stated weight limit compared with the configuration.

Any NX | C or NX | Power Hinge order that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (Roto publishes no price list, so this validator produces no price build-up or line-item quote), other Roto hinge sides such as NX | P130, other hardware families, TiltFirst sensors, strikers and handles, glazing and regional terms.

Where rules-based CPQ gets it wrong
Click to expand
    
Our assessment of what a typical rules-based CPQ (product rules, price rules and validation rules, as in Salesforce CPQ) does with the same cases. It is a judgment about effort and reliability, not a claim that nothing can be built.

    
What the validator caughtTypical rules-based CPQPredictika
A weight limit that depends on material and optionsOnly with workarounds
The limit moves with frame material, threshold, load transfer, turn restrictor and fastening plate, so the rules span several choices and interact.		All the choices arrive together and the limit is worked out from them on every call.
Different size and weight ranges per hinge sideOnly with care
Each hinge side has its own width, height and weight range, so a rule set per hinge side has to be kept in step as the range grows.		The hinge side is one more choice in the same request; its ranges are checked together with everything else.
Variants with their own limitsOnly with care
Comfort ventilation changes the limits and the allowed operations, so it needs cross-field rules that must stay in step with the rest.		The variant and the operation arrive together and are checked against the variant limits.
A recommendation that needs a personOnly with care
A recommended rebate depth or an added central hinge is neither allowed nor forbidden; a rules engine tends to treat it as one or the other.		Recommendations come back as approval items next to the blocking findings.
Every problem returned in one answerOnly with workarounds
Rules tend to fire as the order is saved or a step is completed, so a rep often fixes one error and meets the next.		All findings come back together, whatever order the choices arrived in.

Every rule is checked on every call, in any order the choices arrive; one problem never hides another. Blocking findings stop the quote; approval findings need a person to sign off; everything else is computed.

The text of the narrated walkthrough, step by step.

    
    
      
  1. Welcome to a demo of Predictika's Validator. An AI sales agent prepares a hardware order for a window fabricator: a Roto NX hinge side, frame material, sash size, and more. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the public technical limits and returns a verdict, every reason and the figures it computed.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. Please quote the Roto NX | C concealed hinge side for a PVC Tilt&Turn window, sash rebate 1,800 mm wide by 2,200 mm high. The order states a permitted sash weight of 150 kg. The rest of the request is on screen.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with three findings, all in one answer. The sash rebate width is 1,800 mm; the NX | C range is 340 to 1,750 mm (the minimum depends on the profile). The sash weighs 140 kg, but this configuration is listed up to 120 kg. NX | C: 120 kg standard, 100 kg with a threshold, 150 kg (PVC) or 180 kg (timber, fastening plate above 150 kg) with load transfer and turn restrictor, comfort ventilation 80 kg tilt-only and 100 kg turn-only. Power Hinge: 200 kg Tilt&Turn, 300 kg Turn-Only. The order states a permitted sash weight of 150 kg, but the configuration is listed up to 120 kg.
    6. 
      
  6. The validator returned three blocking findings in one answer. A check that reads one field at a time would pass most of this; it shows only when the choices in the quote are checked against each other.
    7. 
      
  7. What this shows: for a weight limit that depends on material and options, a rules-based CPQ can do this only with workarounds.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the sash rebate width to 1,700 mm, the load transfer to yes and the turn restrictor to yes.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. This time the validator clears it.
    12. 
      
  12. All three earlier findings are cleared, and the validator's figure matches the quote.
    13. 
      
  13. Three problems caught in one call, fixed in one pass, and a clean quote. That is the value of Predictika's validator: catching mistakes before they reach the customer. Now you can try the other scenarios yourself.
    14.
