Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If an external operating unit is used to control the household appliance, then the ease of operation is improved, but the measurement precision of the operating conditions deteriorates

Engineering Contradiction:

Improveease of operationVSAvoidmeasurement precision

Core Design Contradiction:

Ease of operationVSMeasurement precision

Solution Approach 1:

The patent replaces mechanical contact-based control with wireless communication between the operating unit and the household appliance. The operating unit communicates operating conditions wirelessly to the appliance, eliminating the need for physical connection while maintaining control functionality. This substitution enables easier operation through wireless interaction while the appliance's internal sensors and processors accurately measure and interpret the transmitted operating conditions, thus resolving the contradiction between ease of operation and measurement precision.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If the operating unit is moved relative to the household appliance to set operating conditions, then the adaptability is improved, but the reliability of accurate detection deteriorates

Engineering Contradiction:

ImproveadaptabilityVSAvoidreliability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent replaces mechanical position-based control with wireless communication that transmits operating conditions directly. The operating unit can be moved freely without affecting detection reliability, as the appliance receives and processes the transmitted operating conditions through its communication interface and processor. This enables high adaptability in operating unit positioning while maintaining reliable detection of operating conditions through the wireless communication system.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent implements a feedback mechanism where the household appliance receives operating conditions from the operating unit, processes them through its processor, and executes the corresponding operations. The appliance can also provide feedback information back to the operating unit, ensuring accurate detection and interpretation of operating conditions regardless of the operating unit's position, thus maintaining reliability while enabling adaptability.

Inventive Principle:

Principle #23Feedback
