Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a terminal device serves as a sensing receiving node or sensing transmitting node, then sensing functionality is achieved, but energy consumption overhead increases significantly

Engineering Contradiction:

Improvesensing functionalityVSAvoidenergy consumption overhead

Core Design Contradiction:

Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The patent applies preliminary action by having the candidate sensing auxiliary device send indication information before actually participating in the sensing process. The indication information includes condition met status that is determined in advance, allowing the network to pre-identify suitable devices and avoid assigning sensing tasks to devices that would incur excessive energy consumption, thus resolving the contradiction between enabling sensing functionality and reducing energy overhead.

Inventive Principle:

Principle #10Preliminary action

2Device complexity

If the network selects sensing auxiliary devices without condition-based indication, then device selection is simplified, but energy consumption increases due to unnecessary sensing operations

Engineering Contradiction:

Improvedevice selection processVSAvoidenergy consumption

Core Design Contradiction:

Device complexityVSLoss of energy

Solution Approach 1:

The patent implements feedback by having the candidate sensing auxiliary device actively send indication information to the network, including its condition met status. This feedback mechanism allows the network to receive real-time information about device suitability and use it to make informed selection decisions, thereby avoiding energy waste while maintaining an efficient selection process.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The candidate sensing auxiliary device performs self-assessment by determining whether its conditions are met and autonomously sending indication information to the network. This self-service approach eliminates the need for complex network-side evaluation procedures while enabling energy-efficient device selection, as each device self-evaluates its suitability before participating in sensing operations.

Inventive Principle:

Principle #25Self-service

3Measurement precision

If indication information is sent by candidate sensing auxiliary devices, then accurate device selection is achieved, but communication overhead increases

Engineering Contradiction:

Core Design Contradiction:

Measurement precisionVSQuantity of substance

Solution Approach 1:

The patent extracts only the essential information needed for device selection by having the candidate sensing auxiliary device send indication information that specifically includes condition met status. This extraction approach filters out unnecessary data and communication details, allowing the network to obtain precise selection criteria while minimizing communication overhead.
