Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If continuous detection of biological feature information is performed, then the incoming call volume can be automatically adjusted, but the system power consumption increases

Engineering Contradiction:

Improveautomatic volume adjustmentVSAvoidsystem power consumption

Core Design Contradiction:

Extent of automationVSUse of energy by moving object

Solution Approach 1:

The patent implements periodic detection instead of continuous detection by setting detection windows with specific durations (first duration for initial detection, fourth duration for subsequent detections) and intervals between them (second duration). This periodic approach maintains automatic volume adjustment capability while significantly reducing power consumption by keeping the detection system inactive during intervals.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The patent performs preliminary detection using the optical proximity sensor to determine whether to initiate full biological feature detection. By checking the optical proximity sensor condition first, the system prepares and conditions the detection process, avoiding unnecessary activation of power-intensive components when conditions are not met.

Inventive Principle:

Principle #10Preliminary action

2Use of energy by moving object

If manual volume adjustment is required, then power consumption is reduced, but user convenience deteriorates

Engineering Contradiction:

Improvepower consumptionVSAvoidvolume adjustment convenience

Core Design Contradiction:

Use of energy by moving objectVSEase of operation

Solution Approach 1:

The system performs self-service by automatically adjusting the incoming call volume based on detected biological feature information without requiring user intervention. The device monitors its own state and environment, then autonomously modifies audio output, eliminating the need for manual volume button operations while maintaining power efficiency through conditional detection.

Inventive Principle:

Principle #25Self-service

3Measurement precision

If detection duration is increased, then detection accuracy improves, 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:

The patent divides detection into periodic cycles with alternating active and inactive phases. Detection windows (first duration, fourth duration) provide sufficient sampling time for accurate biological feature measurement, while intervals (second duration) between windows allow power reduction. This periodic structure balances measurement precision requirements with power consumption constraints.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The system performs partial detection by using the optical proximity sensor as a preliminary check before initiating full biological feature detection. This partial action approach provides a quick filter that avoids complete detection cycles when conditions are not favorable, reducing overall power consumption while maintaining detection accuracy when needed.

Inventive Principle:

Principle #16Partial or excessive action
