AUDIENCE II // HEIGHT-GAP COUPLES & SPINE HEALTH BIOHACKERS

Two biometries in one matrix: when a 25 cm height gap no longer means lower-back pain

Q: How do I accurately measure my bent-elbow height at home?

Put on the house shoes you normally wear while cooking. Stand upright, relax your shoulders, and bend your arm at 90 degrees with your forearm parallel to the floor. The vertical distance from the floor to the underside of your elbow in millimeters is your baseline H_elbow parameter.

Q: How does a 3-height stepped counter look architecturally clean?

In contemporary kitchen architecture, the cascade is realized either by separating monolithic blocks (a raised wet/sink block, a mid-level prep run, and a lowered cooking island) or via precision CNC-stepped stone planes aligned to the System 32 grid.

In a standard 860 mm kitchen, a tall partner (188 cm) experiences L4–L5 lumbar strain after 15 minutes of chopping, while a shorter partner (160 cm) has to shrug their shoulders over tall pots. furnigen's dual-biometry solver splits zone heights across the room and integrates a 100 mm motorized Linak actuator with saved Profile A and Profile B memory.

Interactive Anatomical Kitchen Compiler (BioCAD v2.4)

Adjust your biometric inputs — the real-time solver recalculates all three worktop planes per AMK formulas, mirrors the 5-zone Blum Dynamic Space vector for right- or left-handed kinematics, and outputs live System 32 → ViyarPRO XML code.

How Mathematics Resolves a Height Gap Between Partners

Split base heights across kitchen lines

When Partner A is 191 cm (elbow 1150 mm) and Partner B is 163 cm (elbow 985 mm), we compile the sink and primary prep run for the taller partner (1025 mm) and calibrate the cooking island and secondary prep zone for the shorter partner (860 mm).

100 mm motorized range per the AMK standard

Following rule amk.work_height.adjustable_range (AMK, p. 11), the primary prep station integrates a whisper-quiet linear actuator frame with a 100 mm stroke and two memory presets: Profile A and Profile B.

Golden storage strata at 400–1200 mm

All daily tools, spices, and heavy cookware live in Strata 2 and 3 (knee to elbow level) inside full-extension Legrabox pull-outs — neither partner ever has to tiptoe or crouch.

Four Stages of the Direct-to-CNC Pipeline: Zero Showrooms

01 // Body Digitization & RoomPlan LiDAR

Scan your kitchen with an iPhone in 40 seconds and enter your elbow height. Our anthropometric module (person.ts built on MakeHuman CC0) places a true-scale 1:1 3D rig of your body inside the virtual kitchen.

02 // Validation Against the 87-Rule Knowledge Base

The constraint solver automatically checks German AMK ergonomics, Blum Dynamic Space kinematics, DBN V.2.5-20 gas clearances, and DBN V.2.5-23 wet-zone electrical safety — citing the exact clause and page for every check.

03 // System 32 Parametric Recalculation

Instead of rigid 600 mm boxes and ugly 80 mm corner filler strips, the solver scales every cabinet width in 1 mm increments and computes 1200+ CNC drilling coordinates on a 32 mm pitch with a 37 mm front setback.

04 // Direct Export to ViyarPRO XML v24 & 1:1 AR

Walk through your compiled kitchen at 1:1 scale via iOS Quick Look (.usdz), then send the ViyarPRO XML v24 production file straight to automated CNC panel saws, PUR edgebanders, and drilling centers.
