Solution Overview

Problem

Beverage bottling plants face complexity and increased operating costs due to central control cabinets requiring complex electrical connections and constant compressed air pressurization to prevent fluid ingress and damage to electronic modules.

Innovation Solution

A device with a housing containing an electromechanical actuator and an electronics module, where a plug-in device welded to the housing provides a fluid-tight seal for electrical contacting, eliminating the need for compressed air pressurization and allowing decentralized module arrangement, simplifying maintenance and replacement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a central control cabinet with cable bushings is used to control electromechanical actuators, then electrical contacting can be achieved, but the device complexity and manufacturing complexity increase due to complex cable routing and sealing requirements

Engineering Contradiction:
Improveelectrical contactingVSAvoidcable routing and sealing
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent divides the control system into decentralized control units, each housing an electronics module and electromechanical actuator together. This segmentation eliminates the need for a central control cabinet and complex cable routing, as each unit is self-contained and requires minimal external connections.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent extracts the electronics module from the central control cabinet and places it directly into the housing with the electromechanical actuator. This extraction eliminates the intermediary cable connections and sealing bushings, simplifying both the control cabinet and the actuator housing.

Inventive Principle:
Principle #2Taking out (Extraction)

2Object-affected harmful factors

If compressed air pressurization is applied to the central control cabinet, then fluid ingress is prevented, but operating costs increase due to continuous energy consumption

Engineering Contradiction:
Improvefluid ingress preventionVSAvoidcompressed air pressurization
Core Design Contradiction:
Object-affected harmful factorsVSUse of energy by stationary object

Solution Approach 1:

The welded sealing connection provides passive, permanent protection against fluid ingress without requiring active systems like compressed air pressurization. The weld creates a self-sustaining seal that requires no energy input to maintain its protective function.

Inventive Principle:
Principle #25Self-service

3Object-affected harmful factors

If cable bushings are sealed in central control cabinets, then fluid-tight sealing is achieved, but maintenance and replacement complexity increase due to time-consuming disassembly and reassembly

Engineering Contradiction:
Improvefluid-tight sealingVSAvoidmaintenance and replacement
Core Design Contradiction:
Object-affected harmful factorsVSEase of repair

Solution Approach 1:

By creating a self-contained control unit with the electronics module housed directly with the actuator, the system enables independent replacement of faulty units without affecting other components. This modular segmentation simplifies maintenance by allowing quick swap-out of individual units rather than working within a complex centralized system.

Inventive Principle:
Principle #1Segmentation

4Reliability

If additional grounding measures are implemented for the housing, then electrical safety is improved, but device complexity increases

Engineering Contradiction:
Improveelectrical safetyVSAvoidgrounding measures
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines the sealing function and the grounding function into a single welded connection between the housing and the electronics module housing. The weld seam simultaneously provides fluid-tight sealing and electrical continuity for grounding, eliminating the need for separate grounding components or measures.

Inventive Principle:
Principle #5Merging (Combining)
