Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a monitoring system is implemented to continuously track performance, then performance monitoring accuracy is improved, but device complexity increases

Engineering Contradiction:
Improveperformance monitoring accuracyVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

A control device acts as an intermediary between measurement devices and the processing system. The control device receives data from multiple measurement devices, processes it centrally, and generates performance indicators. This intermediary approach consolidates the complexity into a single device rather than distributing it across the entire system, thereby improving monitoring accuracy while managing device complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system implements continuous feedback loops where performance indicators are calculated from measurement data and used to detect inefficiencies. The feedback mechanism enables automatic detection of underperforming units and triggers adjustments to processing parameters, improving monitoring precision through systematic data collection and analysis without proportionally increasing overall system complexity.

Inventive Principle:
Principle #23Feedback

2Productivity

If performance monitoring is increased to reduce product loss, then productivity is improved, but use of energy increases

Engineering Contradiction:
Improveproduct loss reductionVSAvoidenergy consumption
Core Design Contradiction:
ProductivityVSUse of energy by moving object

Solution Approach 1:

The control device continuously receives data from measurement devices and calculates performance indicators in real-time. When inefficiencies are detected through feedback comparison against expected performance levels, the system automatically adjusts processing parameters to optimize productivity and reduce product loss. This feedback-driven approach ensures energy is used efficiently by only adjusting parameters when performance deviations are detected, rather than continuous high-energy monitoring and adjustment.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The processing system performs self-diagnosis and self-adjustment through automated inefficiency detection. When the control device identifies underperforming units based on performance indicators, it automatically adjusts processing parameters without requiring external intervention. This self-service capability reduces the need for continuous high-energy monitoring and manual adjustments, optimizing the balance between productivity improvement and energy consumption.

Inventive Principle:
Principle #25Self-service

3Reliability

If continuous monitoring is implemented to ensure food safety, then reliability is improved, but loss of time increases

Engineering Contradiction:
Improvefood safety monitoringVSAvoidprocessing time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system implements continuous monitoring of performance indicators without interrupting the food processing flow. Measurement devices continuously collect data from the processing system, and the control device continuously calculates performance indicators in the background. This continuous action ensures food safety is monitored at all times while maintaining uninterrupted processing, preventing time loss that would occur with periodic sampling or stop-and-check approaches.

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

The control device serves as an intermediary that processes monitoring data without interfering with the primary food processing operations. By centralizing the analysis of performance indicators and inefficiency detection in the control device, the system maintains continuous food safety monitoring while allowing the processing system to operate without interruption. The intermediary processes information in parallel, ensuring reliability without adding sequential time delays to the processing workflow.

Inventive Principle:
Principle #24Intermediary (Mediator)
