Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the positioning chip activates all functions by default to ensure positioning accuracy, then positioning reliability is improved, but power consumption increases

Engineering Contradiction:

Improvepositioning reliabilityVSAvoidpower consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The positioning chip dynamically adjusts its working mode (first working mode with higher power consumption for accurate positioning, second working mode with lower power consumption for power saving) based on real-time positioning requirements and application scenarios, rather than operating in a fixed state

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes operational parameters by switching between different working modes of the positioning chip, adjusting power consumption levels and positioning accuracy parameters according to the specific application scenario and user needs

Inventive Principle:

Principle #35Parameter changes

2Measurement precision

If the positioning chip uses high-precision positioning mode continuously, then positioning accuracy is improved, but battery life decreases

Engineering Contradiction:

Improvepositioning accuracyVSAvoidbattery life

Core Design Contradiction:

Measurement precisionVSDuration of action of stationary object

Solution Approach 1:

The system periodically evaluates positioning requirements and switches between high-precision and power-saving modes based on whether accurate positioning is currently needed, rather than maintaining high-precision mode continuously

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The system applies high-precision positioning only when necessary (partial action) rather than continuously, using full precision capabilities only during critical positioning moments and reducing precision during non-critical periods to conserve battery

Inventive Principle:

Principle #16Partial or excessive action

3Adaptability or versatility

If the positioning chip operates in high-power mode to meet diverse application requirements, then adaptability is improved, but energy efficiency deteriorates

Engineering Contradiction:

Improveapplication adaptabilityVSAvoidenergy efficiency

Core Design Contradiction:

Adaptability or versatilityVSLoss of energy

Solution Approach 1:

The positioning chip dynamically adapts its working mode based on the specific application scenario and positioning requirements, switching between first and second working modes to match the actual needs rather than operating in a fixed high-power state

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes the operational parameters of the positioning chip by selecting different working modes according to application type, adjusting power consumption and performance parameters to match the specific requirements of each application scenario

Inventive Principle:

Principle #35Parameter changes
