Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If continuous biological feature detection is performed to enable automatic volume adjustment, then user convenience is improved, but system power consumption increases

Engineering Contradiction:
Improvevolume adjustment convenienceVSAvoidsystem power consumption
Core Design Contradiction:
Ease of operationVSUse of energy by moving object

Solution Approach 1:

The system performs biological feature detection at specific intervals rather than continuously. Detection is triggered periodically or based on specific conditions (such as incoming call events), allowing the system to balance between monitoring user needs and conserving battery power.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The system automatically detects biological features and adjusts volume without requiring manual user input. The device serves itself by monitoring its own state and making autonomous decisions about volume adjustment based on detected physiological signals.

Inventive Principle:
Principle #25Self-service

2Measurement precision

If biological feature detection is performed at high frequency to improve detection accuracy, then measurement precision is improved, but power consumption increases

Engineering Contradiction:
Improvebiological feature detection accuracyVSAvoiddetection power consumption
Core Design Contradiction:
Measurement precisionVSUse of energy by moving object

Solution Approach 1:

Instead of continuous high-frequency detection, the system uses periodic detection at optimized intervals. This maintains sufficient measurement precision for detecting relevant biological changes while significantly reducing the energy burden of constant monitoring.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The system dynamically adjusts detection parameters such as sampling rate and detection threshold based on current operational conditions. This allows high precision when needed (e.g., during active calls) while reducing precision requirements during idle periods to save power.

Inventive Principle:
