Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by stationary object

If the refrigerator operates based on predetermined temperature settings, then the temperature control is simple, but the power consumption increases and cooling efficiency decreases

Engineering Contradiction:
Improvepower consumptionVSAvoidcontrol system complexity
Core Design Contradiction:
Use of energy by stationary objectVSDevice complexity

Solution Approach 1:

The refrigerator performs preliminary learning of usage patterns during an initial period, storing action data and time data in advance. This pre-acquired knowledge enables the refrigerator to predict future door openings and adjust compressor operations proactively, reducing power consumption without requiring complex real-time decision-making systems.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The refrigerator implements a feedback mechanism where actual door opening actions are recorded as action data, compared with predicted actions, and used to continuously improve prediction accuracy. This closed-loop learning system refines the usage pattern model over time, enabling progressively better energy optimization without increasing control complexity.

Inventive Principle:
Principle #23Feedback

2Measurement precision

If the refrigerator learns usage patterns individually, then the learning process is simple, but the prediction accuracy is insufficient

Engineering Contradiction:
Improveprediction accuracyVSAvoiddata processing complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The refrigerator merges its individual usage pattern data with aggregated data from multiple other refrigerators. By combining action data and time data from a plurality of refrigerators, the system creates a more comprehensive and accurate prediction model, improving prediction accuracy while distributing the data processing burden.

Inventive Principle:
Principle #5Merging (Combining)

3Measurement precision

If the refrigerator accumulates data over a long period, then the learning accuracy improves, but the time required for adaptation increases

Engineering Contradiction:
Improvelearning accuracyVSAvoidadaptation time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The refrigerator performs preliminary data accumulation during a predetermined learning period, storing action data and time data in advance. This pre-acquired data foundation enables faster convergence to accurate predictions, reducing the overall adaptation time while maintaining high learning accuracy.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The refrigerator copies and utilizes aggregated usage pattern data from other refrigerators to supplement its own learning process. This copying mechanism allows the refrigerator to benefit from collective experience, achieving accurate predictions more quickly without requiring extensive individual data accumulation.

Inventive Principle:
Principle #26Copying
