Wet circuit
A flip up straw inlet leads to a stainless cavity. Two ceramic gears are proposed to sit together in that wet side cavity as one illustrated metering package.
MODULE / CARE 01 · PROPOSED SYSTEM STUDY
A focused engineering direction for the GULPR prototype: a proposed wet circuit, a separate dry electronics bay, and access considered within the illustrated 1 L and 2 L bottle forms.
Functional prototype in active testing. This is product direction, not a care manual or a statement of validated performance.

ARCH / 02 · WET AND DRY SYSTEM BOUNDARY
The design study separates the proposed water path from the electronics context. That separation is an engineering direction to investigate, not an instruction for owners to access, remove, or service a product.
A flip up straw inlet leads to a stainless cavity. Two ceramic gears are proposed to sit together in that wet side cavity as one illustrated metering package.
A separate dry electronics bay is proposed beside the wet circuit, with silicone fill shown as a direction for the protected region.
Seal performance, fill method, and electrical protection are unvalidated.
ACC 03 · FULL DIAMETER OPENING
The 1 L and 2 L directions are both drawn around a proposed full diameter opening. It is intended to keep the interior and the illustrated access path under consideration from the first layout.
Final dimensions, grades, fit, tolerances, and the performance of any access path remain to be engineered. The rendered opening is not a hygiene, dishwasher, waterproof, or cleaning claim.

MAT / 04 · MATERIAL AND ACCESS PALETTE
These rows describe the proposed component language behind the prototype. They do not establish final grades, dimensions, supplier selections, or finished construction.

SVC 05 · ACCESS CONCEPT
The wet side insert is a design study for grouping the straw, stainless cavity, and two ceramic gears away from the proposed dry electronics bay. It is not an operating sequence.
The companion brush direction layers a sidewall bristle barrel, upper halo, lower skirt, and detail dome. It is an illustrated approach to access research, not a confirmed bundle or a performance claim.
VFY / 06 · NOT TEST RESULTS
The prototype work has an agenda, not published results. These are the checks that must inform any eventual service, material, sealing, or calibration claim.
GULPR is a functional prototype in active testing. Final care instructions belong with confirmed product details, not with an early design study.
