Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If sensors operate periodically to obtain information, then information availability is improved, but power consumption increases

Engineering Contradiction:
Improveinformation availabilityVSAvoidpower consumption
Core Design Contradiction:
Loss of informationVSUse of energy by moving object

Solution Approach 1:

The sensor operation schedule is made dynamic by adjusting operation frequencies based on terminal status (e.g., active, standby, sleeping modes) and environmental conditions. The controller dynamically modifies the operation schedule to match current operational requirements, thereby reducing unnecessary sensor operations and power consumption while maintaining information availability when needed.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The operation frequency parameter of sensors is changed based on terminal status and environmental factors. Instead of fixed periodic operation, the system adjusts the operation interval parameter dynamically - increasing intervals during low-activity states and decreasing intervals during high-activity states, thus optimizing the balance between information availability and power consumption.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If sensors operate frequently to ensure information accuracy, then measurement reliability is improved, but resource wastage increases

Engineering Contradiction:
Improveinformation accuracyVSAvoidresource wastage
Core Design Contradiction:
ReliabilityVSLoss of substance

Solution Approach 1:

The system dynamically adjusts sensor operation frequency based on terminal status and environmental conditions. During stable conditions, operation frequency is reduced to minimize resource wastage. During changing conditions or critical operations, frequency is increased to maintain information accuracy, thus dynamically balancing reliability and resource consumption.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

Instead of continuous full-frequency sensor operation, the system applies partial action by operating sensors at reduced frequencies during periods when full accuracy is not critical. The operation schedule is optimized to provide sufficient information accuracy only when necessary, accepting partial reduction in measurement frequency during non-critical periods to conserve resources.

Inventive Principle:
Principle #16Partial or excessive action
