Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If lower energy wireless P2P communication technique is used for service discovery and advertisement, then power consumption is reduced, but service connection capability is limited

Engineering Contradiction:

Improvepower consumptionVSAvoidservice connection capability

Core Design Contradiction:

Use of energy by moving objectVSReliability

Solution Approach 1:

The wireless communication process is segmented into distinct phases: service discovery and advertisement using lower energy technique, and service connection and data transfer using higher energy technique. This segmentation allows each phase to use the most appropriate communication method for its specific requirements, reducing overall power consumption while maintaining reliable service connection capability when needed.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system dynamically switches between lower energy and higher energy wireless communication techniques based on the current operational phase and requirements. The switching mechanism enables adaptive selection of communication modes, transitioning from power-saving mode during discovery to high-reliability mode during active service provision, thereby resolving the contradiction between power consumption and connection capability.

Inventive Principle:

Principle #15Dynamics

2Reliability

If higher energy wireless communication technique is used for service connection, then service provision reliability is improved, but power consumption increases

Engineering Contradiction:

Improveservice provision reliabilityVSAvoidpower consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The communication process is divided into phases where higher energy technique is used only for service connection and active data transfer, while lower energy technique handles service discovery and advertisement. This segmentation ensures that higher power consumption is confined to only when absolutely necessary for reliable service provision.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system discards the higher energy communication mode after service connection is established and recovers power by switching to lower energy mode for ongoing communications that do not require high reliability. This cyclical switching pattern minimizes overall power consumption while maintaining service provision reliability during critical phases.

Inventive Principle:

Principle #34Discarding and recovering

3Use of energy by moving object

If lower energy wireless P2P communication technique is used for initial service discovery, then power efficiency is improved, but service discovery speed is reduced

Engineering Contradiction:

Core Design Contradiction:

Use of energy by moving objectVSSpeed

Solution Approach 1:

The lower energy wireless technique is used for partial service discovery functions (advertisement and initial detection), while higher energy technique is reserved for comprehensive service connection and verification. This partial use of lower energy mode achieves acceptable discovery speed for basic functions while maintaining power efficiency, and transitions to higher speed mode when complete service provisioning is required.
