Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If the lighting device is activated only when the object detector detects a moving object, then power consumption is saved, but the lighting device may not be turned on in time for fast-moving objects

Engineering Contradiction:

Improvepower consumptionVSAvoidactivation time

Core Design Contradiction:

Use of energy by moving objectVSLoss of time

Solution Approach 1:

The system performs preliminary action by transmitting sound signals ahead of the moving object's arrival. When an object is detected, sound signals are immediately transmitted through multiple devices in sequence, activating lighting before the object reaches each location. This preliminary activation ensures timely lighting for fast-moving objects while maintaining energy efficiency by activating only along the object's trajectory.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

Sound signals serve as an intermediary carrier to transmit activation information along the object's movement path. The sound generator transmits sound signals that are received by subsequent detection devices, which then trigger lighting activation. This intermediary mechanism enables timely activation without requiring direct line-of-sight or complex prediction algorithms.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If the lighting device is activated early to ensure visibility for fast-moving objects, then safety is improved, but power consumption increases due to unnecessary activation

Engineering Contradiction:

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system applies local quality by activating lighting only at specific locations along the object's movement trajectory rather than uniformly across all areas. Each detection device activates lighting only when it receives sound signals indicating an object is approaching its specific location, ensuring localized and efficient energy usage while maintaining safety along the entire path.

Inventive Principle:

Principle #10Preliminary action

3Reliability

If multiple detection devices are deployed along the object's path to ensure timely lighting activation, then the lighting coverage is improved, but device complexity increases

Engineering Contradiction:

Core Design Contradiction:

Solution Approach 1:

The system merges detection and transmission functions into integrated detection and transmission devices. Each device combines object detection, sound signal transmission, and lighting control capabilities, reducing the need for separate components and simplifying system architecture while maintaining comprehensive coverage along the object's path.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

Each detection device operates autonomously by detecting objects, generating sound signals, and controlling local lighting without requiring centralized control. The devices self-organize into a coordinated system where each unit independently performs its function based on received sound signals, reducing control complexity while ensuring reliable lighting coverage.

Inventive Principle:

Principle #25Self-service
