Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the system relies on user settings for video recording, then the system operates according to user preferences, but the system fails to record in case of serious damage when user settings may not be feasible

Engineering Contradiction:

Improvevideo recording reliabilityVSAvoiduser setting dependency

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system performs preliminary detection of serious damage situations through impact sensors and communication status monitoring before actual video recording is needed. When serious damage is detected, the system automatically switches to forced recording mode without requiring user input, ensuring critical evidence is captured even when users cannot operate the system during emergencies

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system monitors its own operational status through impact sensors and communication modules to automatically determine when forced recording should be activated. The controller independently assesses whether serious damage has occurred and autonomously switches recording modes without external user intervention, making the system self-protective and self-managing in critical situations

Inventive Principle:

Principle #25Self-service

2Reliability

If the system uses the main battery for power supply, then the system operates normally under standard conditions, but the system fails to record when the battery power is cut off due to serious damage

Engineering Contradiction:

Improvepower supply reliabilityVSAvoidpower source adaptability

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The system performs preliminary detection of battery power status through communication modules before power loss occurs. When communication failure or power cut-off is detected, the system proactively switches to alternative power sources (auxiliary battery or super capacitor) to maintain video recording capability, ensuring continuous operation during power transition periods

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system prepares alternative power sources (auxiliary battery and super capacitor) in advance as backup power supplies. When the main battery fails due to serious damage, these pre-prepared power sources immediately take over to maintain system operation and video recording, cushioning against the harmful effect of power loss and preventing recording failure

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

3Measurement precision

If the system performs comprehensive serious damage determination, then the system accurately identifies serious damage situations, but the system complexity increases with multiple detection criteria

Engineering Contradiction:

Improvedamage detection precisionVSAvoiddetection system complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The serious damage detection system is segmented into multiple independent detection modules: impact sensor for physical impact detection, communication status monitor for communication failure detection, and power status monitor for power cut-off detection. Each module independently assesses one aspect of damage, and the controller integrates these segmented detection results to make a comprehensive determination, reducing individual module complexity while maintaining overall detection precision

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The impact sensor and communication module serve multiple functions: they detect both normal operational parameters and abnormal damage conditions. The same impact sensor used for general vibration monitoring also detects serious impact damage, and the communication module used for normal data transmission also detects communication failures indicating serious damage. This multi-functionality reduces the need for separate dedicated detection devices, lowering system complexity while maintaining comprehensive detection capability

Inventive Principle:

Principle #6Universality (Multi-functionality)
