Solution Overview

Problem

Conventional water purification systems face limitations in dispensing reagent grade water remotely without hard-wired connections, leading to entanglement issues with cables, limited flexibility in placement, and the need for extensive cabling and facility remodeling.

Innovation Solution

A wireless transceiver-enabled remote dispensing device that communicates with the main purification unit across a wireless link, allowing for flexible placement and operation without physical electrical connections, enabling multiple remote dispensing devices to be used with a single main unit.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a hard-wired communications link is used to connect the remote dispensing apparatus to the main purification unit, then reliable communication is achieved, but cable entanglement and limited placement flexibility occur

Engineering Contradiction:

Improvecommunication reliabilityVSAvoidplacement flexibility

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces the mechanical cable connection system with a wireless communication system. The remote dispensing apparatus communicates with the main purification unit via wireless signals (e.g., radio frequency communication), eliminating the physical cable that causes entanglement and placement restrictions while maintaining reliable communication control.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If multiple remote dispensing apparatus are connected using separate cables, then multiple dispensing locations are enabled, but extensive cabling and facility remodeling are required

Engineering Contradiction:

Improvenumber of dispensing locationsVSAvoidcabling infrastructure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent replaces the extensive cabling infrastructure with wireless communication technology. Multiple remote dispensing apparatus can connect to the main purification unit simultaneously through wireless signals, enabling multiple dispensing locations without requiring additional cables, electrical outlets, or facility remodeling.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Area of stationary object

If the remote dispensing apparatus is positioned far from the main purification unit, then spatial conservation is achieved, but cable length becomes insufficient or cumbersome

Engineering Contradiction:

Improvebench-top spaceVSAvoidcable length

Core Design Contradiction:

Area of stationary objectVSLength of stationary object

Solution Approach 1:

The patent eliminates the cable length constraint by substituting wireless communication for the mechanical cable connection. The remote dispensing apparatus can be positioned at any distance from the main purification unit within wireless signal range, maximizing spatial conservation on the bench-top without being limited by cable length or creating cumbersome excess cable.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

Wireless methods for dispensing water supplied by a main purification unit to a remote dispensing device. The remote dispensing device is fluidly coupled with the main purification unit. A wireless transceiver is associated with the remote dispensing device and another wireless transceiver is associated with the main purification unit. The wireless transceivers communicate across a wireless communications link between the remote dispensing device and the main purification unit. The system may include multiple remote dispensing devices and/or multiple main purification units.
