Current public engineering snapshot
This page explains the design envelope without publishing exact proprietary geometry or unvalidated release specifications.
Study Range25–50 kHz current UST baseline; 28/40 kHz candidates under research
CouplingLiquid / semi-immersed / controlled rinse coupling
OccupancyUnoccupied appliance only — never operate with humans or animals inside
PlatformShared UST electrical, sensing, control, safety, materials and service architecture
CAD3D CAD neutral workflow; final toolchain not locked
Architecture Notes
What defines this branch
Cleaning conceptRigid-load cleaning uses controlled liquid-coupled acoustic modes, rack geometry, filtration and forced-air finishing.
Frequency strategyCurrent UST baseline is 25–50 kHz; 28/40 kHz dual-mode ideas remain research candidates, not released specifications.
Fluid permissiveThe control system must verify water/coupling state before high-power operation.
Load protectionGlass, ceramic, metal and cookware geometries require hotspot / reflection management and product-specific validation.
Public-IP boundaryEmitter quantity, tank mode shapes, exact power density, rack-field geometry and driver architecture are not published.
Functional Field Concept
Controlled energy, not brute force
Concept visualization only — field shape, emitter count, phase map and exact geometry intentionally not disclosed.
⚠
Occupancy / safety boundaryHard occupancy prohibition. High-power liquid-coupled modes require verified fluid level/coupling; dry-fire and abnormal impedance states inhibit drive.
