Solution Overview

Problem

Existing water treatment and distribution devices are complex and costly due to the use of electronic conductivity sensors and externally positioned delivery valves, which increase production and operating costs and complexity.

Innovation Solution

Integration of delivery valves directly into the carbonator wall near the final distribution terminal, eliminating the need for external valves and electronic level controllers, and using a pressure switch to control the water level and operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If electronic conductivity sensors or probes are used to monitor water level in the carbonator, then water level monitoring is achieved, but equipment complexity and production costs increase

Engineering Contradiction:
Improvewater level monitoringVSAvoidequipment complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent removes electronic conductivity sensors from the carbonator system and replaces them with a mechanical float indicator system. The float rises and falls with water level, providing simple visual monitoring without electronic components, thus eliminating the complexity and cost associated with electronic sensors while maintaining reliable water level monitoring.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent employs simple mechanical components (float, indicator) instead of expensive electronic sensors. These mechanical elements are inexpensive, durable, and eliminate the need for complex electronics, wiring, and control systems, thereby reducing both production and operating costs while maintaining functional reliability.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

2Adaptability or versatility

If delivery valves are positioned outside the carbonator, then water treatment and distribution functions are separated, but additional components (tubes, connectors) are required increasing complexity and costs

Engineering Contradiction:
Improvefunctional separationVSAvoidcomponent complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent integrates the delivery valves directly into the carbonator body, merging the water treatment chamber and distribution valve housing into a single unified structure. This eliminates the need for external tubes, connectors, and mounting brackets, thereby reducing component complexity and assembly requirements while maintaining the functional separation of water treatment and distribution operations.

Inventive Principle:
Principle #5Merging (Combining)

3Ease of operation

If delivery valves are positioned outside the carbonator, then water can be delivered through external terminals, but production and running costs increase

Engineering Contradiction:
Improvewater delivery functionVSAvoidproduction cost
Core Design Contradiction:
Ease of operationVSEase of manufacture

Solution Approach 1:

By integrating delivery valves into the carbonator body, the patent reduces the total number of parts that need to be manufactured, assembled, and sealed. This unified design simplifies the manufacturing process, reduces material requirements, and lowers both production and running costs while preserving the ease of water delivery operation through externally accessible terminals.

AI summary

Device for treating and distributing drinks, particularly water, comprising a carbonator (1) into which a specific body of water (2) and a specific quantity of gas are introduced through suitable supply and pumping means (4, 5, 6, 6') so as to form a cushion (3) of pressurized gas between the upper wall (101) of the carbonator (1) and the body of water (2); the carbonator (1) interacts with a refrigerating system (24) for cooling the body of water (3) and is provided with suitable pipes (22, 25, 26) for transferring the treated water to a set of delivery valves (8, 9, 10) communicating with a terminal (13) for the final distribution of the treated water; the carbonator (1) comprises a pressure switch (20) electrically connected to the water pumping means (5); the pressure switch (20) can detect the pressure in the gas cushion (3) and cause the starting or stopping of the water pumping means (5) if the pressure detected in the gas cushion (3) falls below a certain predetermined value because of the discharge of treated water from the distribution terminal (13), or if it exceeds this predetermined value because of the excessive compression of the gas cushion (3) due to the entry of water into the carbonator (1).
