Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a wearable electrocardiograph is used without a separate lead line, then the device portability and ease of use are improved, but the accuracy of lead direction alignment deteriorates

Engineering Contradiction:

Improveease of useVSAvoidlead direction alignment accuracy

Core Design Contradiction:

Ease of operationVSMeasurement precision

Solution Approach 1:

The patent implements a feedback mechanism where the sensor unit detects the current attachment direction of the electrocardiograph and compares it with the standard lead direction. The control unit then provides real-time feedback guidance to the user through visual or auditory signals, enabling the user to adjust the attachment direction until the measured direction matches the standard direction. This closed-loop feedback system resolves the contradiction by maintaining ease of use while achieving accurate lead alignment.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent replaces the traditional mechanical alignment method (relying on user knowledge of standard lead directions) with an electronic sensing and control system. The sensor unit uses acceleration sensors to detect the attachment direction, and the control unit processes this data to provide guidance, substituting mechanical alignment expertise with electronic measurement and control.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Ease of manufacture

If the electrocardiograph is fixed in a specific direction, then the manufacturing and usage simplicity are improved, but the adaptability to different measurement requirements deteriorates

Engineering Contradiction:

Improveusage simplicityVSAvoidadaptability to different measurement requirements

Core Design Contradiction:

Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent transforms the electrocardiograph from a static, fixed-direction device into a dynamic system that can detect and adapt to different attachment directions. The sensor unit continuously monitors the attachment direction, and the control unit can provide guidance for different standard lead directions (Lead I, Lead II, Lead III, etc.), enabling the same device to adapt to various measurement requirements while maintaining usage simplicity.

Inventive Principle:

Principle #15Dynamics

3Ease of operation

If non-medical personnel use the electrocardiograph without guidance, then the ease of operation is improved, but the measurement accuracy deteriorates

Engineering Contradiction:

Improveease of operationVSAvoidsignal acquisition accuracy

Core Design Contradiction:

Ease of operationVSMeasurement precision

Solution Approach 1:

The patent implements a self-service guidance system where the device automatically detects its own attachment direction and provides guidance signals to the user. The sensor unit measures the current direction, the control unit compares it with standard directions, and the output unit provides intuitive guidance without requiring medical knowledge. This self-service mechanism maintains ease of operation while ensuring measurement accuracy through automated guidance.

Inventive Principle:

Principle #25Self-service
