Method 07

Cross-Component DOE

Problem it solves: You changed one material and the entire product behaved differently — but you do not know why. Was it the material itself, or the way it interacted with the adjacent layer? Without isolating the variable, every fix is a guess, and every guess costs another sample run and another four weeks.

Engineering Process

How It Works

We run a structured Design of Experiments protocol that isolates variables across product layers:


Step 1 — Define the variable matrix: which components to swap, which to hold constant, and what performance metrics to measure. In a recent engagement, this meant 6 material configurations across topsheet, ADL, and core layers.


Step 2 — Execute cross-swap testing: systematically combine components from different products to create hybrid configurations. Each hybrid isolates one variable while controlling others.


Step 3 — Measure against standardized protocols: absorption speed, rewet, retention — tested at multiple load cycles, not just single-pour results that mask real-world failure.


Step 4 — Map the interaction matrix: identify which layer combinations produce synergies and which create conflicts. The output is not a single recommendation — it is a ranked map of the entire solution space.

Why Only CORIO

DOE in diaper product development is rare — not because the concept is complex, but because it requires physical access to multiple competitor products, the testing infrastructure to run controlled experiments, and engineers who understand layer interaction physics rather than just material specifications.


We maintain a rotating library of competitor products sourced from retail channels across multiple markets. When a client engagement requires DOE, the benchmark products are already on the shelf — we do not spend the first three weeks sourcing samples. In our first DOE engagement, this library allowed us to isolate that a competitor's pre-formed central channel in the core — not their topsheet or ADL — was the primary driver of their superior liquid distribution. That finding redirected the entire product development plan away from a topsheet redesign that would have cost months and solved nothing.


Deep Dive

Full Detail

Cross-Component DOE answers a question that standard testing cannot: when a product underperforms, is the problem in the material or in the interaction between materials?

What you receive:

Variable Isolation Matrix — a structured table showing every component swap, the performance delta it produced, and the statistical significance of the difference. You see exactly which layer is responsible for which performance outcome.

Interaction Map — a visual showing which component combinations produce positive synergies and which create conflicts. This prevents the common mistake of optimizing one layer in isolation and degrading another.

Ranked Configuration Table — all tested combinations ranked by the metrics that matter to your product strategy, with trade-off annotations showing where performance gains come at cost or manufacturability penalties.

The most expensive product development mistake is not choosing the wrong material — it is changing the right material because the diagnostic pointed to the wrong layer.
