Categories¶
Open Consumables works one category at a time. The pilot is electric toothbrush heads; everything else is scaffolded but deferred until the pilot ships a published baseline.
Active¶
| Category | Working name | Stage |
|---|---|---|
| Electric toothbrush heads | OpenBrush | Phase 2: physical measurement |
Deferred¶
The categories below are scaffolded as placeholders. None are public-facing yet. Each activates only after the pilot has produced a published measured baseline AND the category has been explicitly chosen as the next step.
| Category | Working name | Why it's a candidate |
|---|---|---|
| Air purifier filters | OpenAir | Strongest follow-on; closest structural analogue of OpenBrush |
| Water purifier cartridges | OpenWater | Multi-stage scope (PP / carbon / RO); each stage may need its own profile |
| Robot vacuum consumables | OpenVac | Heterogeneous mix (4-5 classes per device); widest scope |
| Electric razor heads | OpenShave | Tightest scope; potential fast second proof-of-pattern |
| Electric scooter parts | OpenScoot | Strong M365 / Pro / Essential / 4-series anchor; battery packs out of scope |
| Humidifier filters / wicks | OpenMist | Lowest priority; aftermarket may be too thin |
Why this list and not a longer one¶
Each category passes three gates:
- Category-fit, spec is complete, buyer has opted out of choice, rebuyability beats novelty.
- Existing-layer check, no mature industry or community reference layer already documents the geometry. (This rules out bicycles, motorcycles, mechanical keyboards, 3D printer nozzles, RC connectors.)
- Ecosystem-selection prerequisite, for the convergence-led wedge, a discoverable buyer-side compatibility anchor must already exist. (This rules out Oral-B, Sonicare, most Western IoT brands for the convergence path.)
Categories that don't pass all three are out of scope, even when they superficially look like good candidates.
