Predictika · Linear roller guideway orders

An AI sales agent's roller guideway order, checked before it goes out

An AI sales agent prepares an order for linear recirculating roller bearing and guideway assemblies: size, carriage design, guideway closing method, coating, preload and accuracy class, and the hole pattern of the guideway. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the catalogue rules and returns a verdict, every reason and the figures it computed.

Scope: RUE..-E roller guideway assemblies, sizes 25 to 100: carriage designs, guideway closing, coatings, preload and accuracy classes, hole patterns. See everything this validator covers

This validator models orders for the RUE..-E linear recirculating roller bearing and guideway assemblies (sizes 25, 35, 45, 55, 65 and 100), not just the scenarios shown below.

  • Sizes and designs — carriage designs standard, L, H, HL and SL; size 100 comes only as the long carriage (L) and the narrow long carriage (SL) only in size 65.
  • Guideway closing and coating — standard plugs, steel plugs (sizes 35 to 65), mounting from below, and covering-strip slots ADB and ADK (sizes 25 to 65); the Corrotect and Protect A coated design is available only in accuracy class G2 and preload class V3.
  • Hole pattern — the first and last hole must be at least 20 mm from the guideway ends (30 mm in size 100), and the length less both spacings must be a whole number of hole pitches (30, 40, 52.5, 60, 75 or 105 mm by size); the hole count is computed and compared with the figure the quote states.
  • Load ratings and interchangeability — the basic dynamic load rating of each carriage is taken from the catalogue tables and compared with the quote; carriages and guideways of sizes 65 and 100 have restricted interchangeability, and in accuracy classes G0 and G1 interchangeable-as-required orders need a postscript (both need a person to confirm).

Any RUE..-E order that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (Schaeffler does not publish a price list for these assemblies, so this validator produces no price build-up or line-item quote), the RUE..-F version, ball-type guideways such as KUVE and KLLT, wipers, lubrication units and other accessories, guideway segment counts, height sorting and mounting tolerances.

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
Carriage designs and closing methods that exist only in some sizesOnly with care
A product rule per size and option. It works, but each size has its own exceptions and every catalogue revision means rewriting them.		The size, design and closing method are in one request and every combination is checked together.
Coated systems limited to one accuracy class and one preload classOnly with care
The coating restricts two other choices; a rule per coating and per class can express it, and someone has to keep them in step with the catalogue.		Coating, preload and accuracy are checked together, and each violated restriction is reported on its own.
A hole pattern that must divide into whole pitches, with a size-specific minimum spacingOnly with workarounds
The pitch differs by size, one size has a half-millimetre pitch, and the test is a remainder on length minus both spacings; this is arithmetic that product rules handle poorly.		The length, both spacings and the size-specific pitch are computed on every call, so a pattern that does not fit is caught with the numbers shown.
Stated load rating and hole count that must match the orderOnly with care
A stated figure is a free-entry field; a rule can compare it with a looked-up value, but the lookup tables and the comparison have to be written and maintained.		The stated figures travel with the order and are compared with the computed ones on every call.
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.

  

  

    
What this validator catches: findings from its test cases

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.

    
1That carriage design does not exist in the selected size; size 100 comes only as the long carriage (L), and the narrow long carriage (SL) only in size 65.
2That guideway closing method is not offered for the selected size; size 100 guideways come only with the standard closing plugs, and size 25 has no steel-plug version.
3Coated (Corrotect or Protect A) systems are available only in accuracy class G2; the quote has class G3.
4The coated corrosion-resistant design is available only in preload class V3; the quote has V2.
5Coated (Corrotect or Protect A) systems are available only in accuracy class G2; the quote has class G1.
6The coated corrosion-resistant design is available only in preload class V3; the quote has V5.
7The spacing from the guideway start to the first hole is 15 mm; the minimum for this size is 20 mm.
8The spacing from the guideway end to the last hole is 10 mm; the minimum for this size is 20 mm.
9The spacing from the guideway start to the first hole is 25 mm; the minimum for this size is 30 mm.
10With a start spacing of 20 mm and an end spacing of 40 mm, the 1,540 mm guideway does not divide into a whole number of 52.5 mm hole pitches.
11A 30 mm guideway is too short for a start spacing of 20 mm and an end spacing of 20 mm.
12The quote states a basic dynamic load rating of 92,000 N per carriage; the selected carriage has 114,000 N.
13The quote states 30 holes in the guideway; the length and spacings give 29.
14Carriages and guideways of sizes 65 and 100 are interchangeable only to a restricted extent; a person should confirm with Schaeffler that the pairing is supported.
15Carriages and guideways are interchangeable as required only in accuracy classes G2 and G3; for G0 and G1 the order must carry the postscript Interchangeable as required, and a person should confirm it is added.

The text of the narrated walkthrough, step by step.

    
    
      
  1. Welcome to a demo of Predictika's Validator. An AI sales agent prepares an order for linear recirculating roller bearing and guideway assemblies: size, carriage design, guideway closing method, and more. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the catalogue rules 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 2 RUE100-E roller guideway units, each with 4 carriages on a 2,160 mm guideway, the first hole 30 mm from the start and the last hole 30 mm from the end. The quote states a basic dynamic load rating of 630,000 N per carriage and 21 holes in the guideway. The rest of the request is on screen.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with two findings and one approval, all in one answer. That carriage design does not exist in the selected size; size 100 comes only as the long carriage (L), and the narrow long carriage (SL) only in size 65. That guideway closing method is not offered for the selected size; size 100 guideways come only with the standard closing plugs, and size 25 has no steel-plug version.
    6. 
      
  6. The validator returned two blocking findings and one approval 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 carriage designs and closing methods that exist only in some sizes, a rules-based CPQ is error-prone for this.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the product to RUE100-E-L and the guideway closing to standard closing plugs.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. Not blocked, but held for a person.
    12. 
      
  12. The two blocking findings are cleared; one approval remains for a person: restricted interchangeability in sizes 65 and 100.
    13. 
      
  13. The agent resubmits once more.
    14. 
      
  14. The revised request. It changes the interchangeable parts to no.
    15. 
      
  15. It calls the validator once more.
    16. 
      
  16. This time the validator clears it.
    17. 
      
  17. The earlier finding is cleared, and the validator's figure matches the quote.
    18. 
      
  18. Three problems caught in one call, fixed in two passes, 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.
    19.
