Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual cleaning using harsh chemicals is used, then cleaning effectiveness is improved, but safety risks and operational complexity increase

Engineering Contradiction:
Improvecleaning effectivenessVSAvoidsafety risks from harsh chemicals
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent employs ozone, a strong oxidant, to clean and disinfect dispensing lines. Ozone oxidizes organic deposits and microorganisms, achieving effective cleaning without the safety hazards of harsh chemicals. The system generates ozone on-demand and delivers it through the dispensing lines, allowing thorough disinfection while eliminating the need for manual handling of dangerous substances.

Inventive Principle:
Principle #38Strong oxidants (Accelerated oxidation)

Solution Approach 2:

The patent replaces manual mechanical cleaning operations with an automated electronic control system. The system automatically controls valves, pumps, and ozone generation, eliminating the need for personnel to manually handle cleaning chemicals. This substitution reduces safety risks while maintaining or improving cleaning effectiveness through precise automated control of the cleaning process.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If manual handling of cleaning chemicals is used, then cleaning capability is improved, but labor time and operational complexity increase

Engineering Contradiction:
Improvecleaning capabilityVSAvoidlabor time for chemical handling
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system performs self-service cleaning operations through automated control. The electronic control system automatically manages the cleaning process, including activating valves, controlling fluid flow, and generating ozone as needed. This eliminates the need for manual intervention in chemical handling and reduces labor time while maintaining cleaning capability.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system prepares cleaning solutions and activates components in advance through automated sequencing. The electronic control system pre-positions valves and activates ozone generation before the actual cleaning operation begins, ensuring readiness without requiring manual preparation time. This preliminary automated action reduces overall labor time while maintaining effective cleaning capability.

Inventive Principle:
Principle #10Preliminary action

3Extent of automation

If automated Clean-In-Place system with ozonated water is used, then safety and automation are improved, but system complexity increases

Engineering Contradiction:
Improveautomation levelVSAvoidsystem complexity
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The electronic control system serves multiple functions: controlling valves, managing ozone generation, regulating fluid flow, and monitoring the cleaning process. By consolidating these diverse control functions into a single multi-functional controller, the system achieves high automation without proportionally increasing complexity. The universal controller manages all aspects of the Clean-In-Place operation from a centralized point.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system merges ozone generation, fluid delivery, and control functions into an integrated unit. The ozone generator, valves, pumps, and control system work as a unified automated assembly, reducing the complexity that would arise from separate independent components. This merging allows automated operation while keeping the overall system structure manageable and coherent.

Inventive Principle:
Principle #5Merging (Combining)

4Reliability

If frequent cleaning is performed, then hygiene and quality are improved, but time and resource consumption increase

Engineering Contradiction:
Improvehygiene qualityVSAvoidcleaning frequency time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system implements periodic cleaning cycles automatically scheduled by the electronic control system. Instead of requiring continuous manual intervention, the system performs cleaning at predetermined intervals or based on usage metrics. This periodic automated action maintains high hygiene standards through frequent cleaning while minimizing the time and resources required by eliminating manual labor during each cleaning event.

Inventive Principle:
Principle #19Periodic action

AI summary

An automatic or semi-automatic Clean-In-Place system and method of using same. An automatic or semi-automatic Clean-In-Place system (1;1a;1b) serves for cleaning at least one dispensing line (6a,6b,6c,6d,6e,6f;6a',6b',6c';6a'',6b'',6c'') between a take-off station (2) and a dispensing station (3) with dispensers (5a,5b,5c,5d,5e,5f) at the end of dispensing lines (6a,6b,6c,6d,6e,6f;6a',6b',6c';6a'',6b'',6c'') and is operated by an electronic control system (17). A source of ozonated water (10) provides ozonated water through ozonated water conduit (12) via an ozonated water valve (OWV), and cleaning water (CW) is provide through water conduit (15) via a water valve (WV). A main conduit (14) in turns receives water from the water conduit (15) and ozonated water from the ozonated water conduit (12). The main conduit (14) extends into serially arranged flow distribution units (13;13.2;13.2;13',13.1',13.2';13'',13.1'',13.2''), each comprising serially arranged branch conduits (C1,C2;C1.1,C2.1;C1.2;C2.2) on the main conduit (14). A second coupler (16a,16b;16c,16d;16e,16f) is adapted to couple in fluid communication with a first coupler (8a,8b;8c,8d;8e,8f;9a,9b;8a',8a'',8b',8b'',8c',8c'') at the end of a dispensing line (6a,6b,6c,6d,6e,6f;6a',6b',6c'; 6a'',6b'',6c'').
