Solution Overview

Problem

Existing container treatment systems face malfunctions due to uneven wear of sliding strips and curved guides, which requires manual inspection for wear monitoring, leading to potential operational errors and malfunctions.

Innovation Solution

Incorporation of a marker element, such as a sensor or visual marking, that interacts with the endless drive element to detect lateral displacement caused by wear, allowing for automatic wear signal generation and timely maintenance, reducing the risk of system failure.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If manual inspection methods are used for wear monitoring, then device complexity is reduced, but measurement precision and reliability of wear detection deteriorate

Engineering Contradiction:
Improvecomplexity of wear monitoring systemVSAvoidprecision of wear detection
Core Design Contradiction:
Device complexityVSMeasurement precision

Solution Approach 1:

The patent replaces manual visual inspection with an optical sensor system that automatically detects wear by monitoring the lateral displacement of receiving elements. The sensor converts mechanical displacement into electrical signals, eliminating the need for human operators to visually assess wear conditions while providing precise, objective measurement data.

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

Solution Approach 2:

The wear monitoring system operates autonomously by continuously sensing the position of receiving elements and automatically generating wear signals when displacement thresholds are exceeded. The system serves itself by detecting its own operational state without requiring external human intervention, thereby improving measurement precision while maintaining simple device architecture.

Inventive Principle:
Principle #25Self-service

2Measurement precision

If automatic sensor-based wear detection is implemented, then measurement precision and reliability improve, but device complexity increases

Engineering Contradiction:
Improveprecision of wear detectionVSAvoidcomplexity of wear monitoring system
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent extracts only the essential detection function by using a single optical sensor positioned to detect lateral displacement of receiving elements. Rather than implementing a complex multi-sensor array or comprehensive monitoring system, the invention isolates the critical wear indicator (lateral displacement) and uses a simple sensor to detect it, thereby achieving high measurement precision with minimal added complexity.

Inventive Principle:
Principle #2Taking out (Extraction)

3Reliability

If continuous monitoring is implemented, then reliability of wear detection improves, but use of energy increases

Engineering Contradiction:
Improvereliability of wear detectionVSAvoidenergy consumption of monitoring system
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The optical sensor operates continuously to monitor the position of receiving elements, ensuring that wear detection is always active and reliable. The sensor maintains a constant detection state without interruption, providing uninterrupted wear monitoring data that enhances system reliability while consuming minimal energy due to the low power requirements of optical sensing technology.

Inventive Principle:
Principle #20Continuity of useful action
