Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual user intervention is used to adjust parameters for varying soiling levels, then user control is maintained, but cleaning results become suboptimal due to lack of automatic adjustment

Engineering Contradiction:
Improvemanual parameter adjustmentVSAvoidcleaning result consistency
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The sensor module automatically detects soiling levels and the control unit automatically adjusts operational parameters without user intervention. The system serves itself by using sensor information to determine and execute appropriate cleaning programs, eliminating the need for manual parameter adjustment while ensuring consistent cleaning results.

Inventive Principle:
Principle #25Self-service

2Reliability

If appliance parameters are automatically adjusted based on detergent type, then cleaning optimization is achieved, but results still need improvement in many situations

Engineering Contradiction:
Improvecleaning result optimizationVSAvoidadaptability to varying soiling scenarios
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The sensor module provides real-time feedback on actual soiling conditions during the cleaning process. The control unit receives this sensor information and dynamically adjusts operational parameters based on the detected soiling level, creating a closed-loop control system that adapts to varying scenarios and continuously optimizes cleaning results.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system transitions from static parameter adjustment based solely on detergent type to dynamic parameter adjustment that responds to real-time sensor information about soiling levels. The operational parameters are continuously adapted during the cleaning process based on actual conditions detected by the sensor module.

Inventive Principle:
Principle #15Dynamics

3Reliability

If an electrochemical energy storage device is added to power the dispensing and sensor modules, then operational reliability is improved, but device complexity increases

Engineering Contradiction:
