Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the display device continuously monitors input terminal coupling and video signal input to enable automatic starting, then the convenience of operation is improved, but the standby power consumption increases

Engineering Contradiction:

Improveautomatic starting convenienceVSAvoidstandby power consumption

Core Design Contradiction:

Ease of operationVSUse of energy by moving object

Solution Approach 1:

The patent implements dynamic operation modes that can switch between different starting conditions (automatic start based on coupling detection, automatic start based on signal detection, and manual start). The system dynamically adjusts its monitoring behavior and power consumption characteristics based on user-selected modes, allowing flexibility between convenience and energy efficiency.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes the operational parameters of the display device by introducing multiple starting condition modes. By modifying the trigger conditions for automatic starting (from continuous monitoring to event-based detection), the system optimizes the balance between operational convenience and power consumption during standby states.

Inventive Principle:

Principle #35Parameter changes

2Reliability

If the display device monitors video signal input to determine starting condition, then the reliability of automatic start is improved, but the complexity of detection increases

Engineering Contradiction:

Improveautomatic start reliabilityVSAvoidsignal detection complexity

Core Design Contradiction:

ReliabilityVSDifficulty of detecting and measuring

Solution Approach 1:

The patent segments the automatic starting function into distinct modes: coupling detection mode and signal detection mode. This segmentation allows the system to implement different detection strategies for different scenarios, reducing overall complexity while maintaining reliability. Each mode has its own specific detection criteria and trigger conditions.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent performs preliminary detection of input terminal coupling status before attempting video signal input detection. This preliminary action allows the system to prepare for automatic starting by first establishing connection status, then proceeding to signal detection only when necessary, thereby improving reliability while managing detection complexity through staged processing.

Inventive Principle:

Principle #10Preliminary action
