1. Market Need & Pain Point Analysis

1.1 The Toilet Flush Friction

Traditional toilet flush mechanisms — whether push-button, lever, or pull-chain — require physical contact with the flush control. In public restrooms, this contact point becomes a vector for cross-contamination. In home bathrooms, cleaning the flush button and surrounding area is an ongoing maintenance chore. The universal demand for touch-free flushing has driven rapid growth in sensor-based toilet flush solutions worldwide.

However, the retrofit market faces a critical barrier: most existing toilets were not designed with sensor integration in mind. Retrofitting typically requires drilling, wiring, and modifications that are beyond the capability of average consumers and too costly for property managers at scale.

1.2 The GIBO B2 Solution

The GIBO B2 wave-sensing flush assembly is a complete, self-contained retrofit solution that transforms any standard toilet into a touch-free flush toilet. The assembly integrates a pulse latching solenoid valve, an IR wave sensor module, and a battery-powered control board into a single compact unit that installs between the existing water supply line and the toilet tank inlet. A simple hand wave in front of the sensor triggers a complete flush cycle — no contact, no wiring, no plumbing modifications beyond basic hose connections.

The pulse latching solenoid valve (Core Technology #4) is the key enabler of battery-powered operation. Unlike conventional solenoid valves that require continuous power to maintain the open state, the latching valve uses a brief current pulse to toggle between open and closed states, consuming zero holding power. This design achieves years of battery life from standard AA batteries even under heavy daily use.

2. Core Technology

2.1 IR Wave Gesture Recognition

The B2 employs an optimized IR sensing algorithm specifically tuned for the rapid hand-wave gesture. Unlike simple proximity detection, the B2's signal processing chain analyzes the temporal profile of the IR reflection — rise time, dwell duration, and fall time — to distinguish an intentional wave from incidental body movement or ambient interference. This multi-parameter gesture recognition dramatically reduces false triggers while maintaining sub-200ms response time.

2.2 Pulse Latching Solenoid Valve

The integrated pulse latching solenoid valve (GIBO Core Technology #4) represents a breakthrough in battery-powered fluid control. A single 50ms current pulse opens the valve for the flush cycle; a second pulse closes it after the programmed flush duration. Between cycles, the valve mechanically maintains its state with zero electrical power consumption. This bistable mechanical design is the foundation of the B2's multi-year battery life, making it practical for installations where frequent battery changes would be unacceptable.

2.3 Ultra-Low-Power Control Architecture

Building on GIBO Core Technology #6 (Low-Power Multi-Stable Agile Sensing), the B2 control board achieves standby current below 15μA through aggressive duty-cycling of all active components. The microcontroller spends >99% of its time in deep sleep, waking only for millisecond-level sensing scans every 200ms. This power management strategy enables 24+ months of operation from a set of 4 AA alkaline batteries at 50 daily activations.
