Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple electronic devices communicate with external devices in various situations, then communication functionality is improved, but battery lifespan is reduced

Engineering Contradiction:

Improvecommunication functionalityVSAvoidbattery lifespan

Core Design Contradiction:

Adaptability or versatilityVSDuration of action of moving object

Solution Approach 1:

The system divides multiple electronic devices into primary and secondary roles based on wearing position information. The primary device handles communication with the external device while secondary devices listen to audio data, segmenting communication tasks to reduce overall energy consumption and extend battery lifespan.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent implements dynamic role assignment where devices switch between primary and secondary roles based on real-time wearing position detection. This dynamic adjustment optimizes communication efficiency and battery usage by assigning roles according to actual usage scenarios rather than fixed configurations.

Inventive Principle:

Principle #15Dynamics

2Productivity

If devices dynamically adjust roles based on wearing position, then communication efficiency is improved, but device complexity increases

Engineering Contradiction:

Improvecommunication efficiencyVSAvoidrole determination mechanism

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The system uses wearing position information feedback from the external device to automatically determine primary and secondary roles. This feedback mechanism enables efficient communication by continuously monitoring and adjusting device roles based on actual wearing conditions without requiring complex manual configuration.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

Devices autonomously determine their own roles based on received wearing position information without external intervention. The primary device automatically identifies itself and assigns secondary roles to other devices, enabling self-organizing communication efficiency while minimizing control complexity.

Inventive Principle:

Principle #25Self-service
