Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If existing pairing techniques are used, then pairing can be performed, but the pairing process is inefficient and lacks reliability

Engineering Contradiction:

Improvepairing reliabilityVSAvoidpairing efficiency

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The patent changes the parameter comparison approach from simple device ID matching to comparing received signal strength indicator (RSSI) with criterion values derived from antenna parameters and distance parameters. This parameter transformation enables more reliable pairing decisions while maintaining efficient processing through standardized calculations.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent performs preliminary calculations of criterion values based on stored antenna parameters and distance parameters before the actual pairing decision. This preliminary action prepares the pairing threshold in advance, making the final pairing judgment faster and more reliable without compromising efficiency.

Inventive Principle:

Principle #10Preliminary action

2Reliability

If simple pairing methods are used, then pairing is fast, but connection security and reliability are insufficient

Engineering Contradiction:

Improveconnection reliabilityVSAvoidpairing method complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent introduces criterion values as an intermediary parameter between the physical antenna properties and the pairing decision. These criterion values mediate the comparison between RSSI and device capabilities, providing a standardized interface that enhances reliability without significantly increasing system complexity.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent segments the pairing decision into distinct components: antenna parameters, distance parameters, criterion value calculations, and RSSI comparison. This segmentation allows each component to be optimized independently while maintaining overall system reliability through their coordinated interaction.

Inventive Principle:

Principle #1Segmentation

3Reliability

If standardized pairing criteria are implemented, then pairing reliability improves, but processing requirements increase

Engineering Contradiction:

Improvepairing criterion reliabilityVSAvoidprocessing energy

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent implements partial action by calculating criterion values only when needed for pairing decisions rather than continuously. The processing unit computes antenna parameters and distance parameters selectively, performing excessive calculations only when pairing is initiated, thus balancing reliability requirements with energy conservation.

Inventive Principle:

Principle #16Partial or excessive action
