Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If users manually adjust the color temperature of the display device, then users can change the display parameters, but users cannot determine how to achieve a better display effect and need multiple trial-and-error adjustments

Engineering Contradiction:

Improvedisplay parameter adjustmentVSAvoidadjustment time

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The display device automatically detects environment light parameters and adjusts its own display parameters without user intervention. The processing unit acquires environment light parameters through a sensor and autonomously determines optimal display parameters, eliminating the need for manual trial-and-error adjustments by users.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system continuously monitors environment light parameters and uses this feedback to dynamically adjust display parameters. The processing unit compares detected environment light conditions with stored correspondence relationships to determine appropriate display settings, creating a closed-loop control system that adapts to changing environmental conditions.

Inventive Principle:

Principle #23Feedback

2Adaptability or versatility

If users manually adjust the color temperature through screen menu, then display parameters can be changed, but the display device may not reach the best display status

Engineering Contradiction:

Improvedisplay adaptation to environmentVSAvoidcolor temperature accuracy

Core Design Contradiction:

Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The patent replaces manual mechanical adjustment (screen menu operations) with an automated optical sensing system. A sensor detects environment light parameters, and a processing unit automatically determines optimal display parameters based on pre-stored correspondence relationships between environment light parameters and display parameters, achieving precise color temperature matching without manual intervention.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system pre-stores multiple correspondence relationships between environment light parameters and optimal display parameters. When the sensor detects current environment light conditions, the processing unit quickly retrieves the corresponding pre-calculated display parameters, avoiding real-time complex calculations and enabling rapid adaptation to environmental changes.

Inventive Principle:

Principle #10Preliminary action
