Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual color correcting gels are used to adjust color temperature, then color temperature adjustment is achieved, but the process becomes time-consuming and labor-intensive
Solution Approach 1:
The patent replaces manual mechanical adjustment of color correcting gels with an automated electronic system. A color temperature meter automatically measures the environmental color temperature, a microprocessor converts this measurement to RGB values, and an LED light control unit electronically adjusts the light output to match the measured color temperature. This substitution eliminates manual intervention entirely, resolving the contradiction between achieving accurate color temperature adjustment and minimizing adjustment time.
Solution Approach 2:
The system performs self-adjustment by automatically measuring the environmental color temperature and adjusting its own light output accordingly. The color temperature meter continuously monitors the environment, and the control system automatically modifies the LED output to match the measured values without requiring human operators. This self-service capability eliminates the time loss associated with manual color temperature adjustment while maintaining high accuracy.
2Measurement precision
If post-processing software is used to adjust color temperature, then color temperature correction is achieved, but considerable time and processing resources are consumed
Solution Approach 1:
The patent performs color temperature adjustment in real-time during the lighting process rather than as a post-processing step. By measuring the environmental color temperature with a color temperature meter and automatically adjusting the LED light output to match before capture, the system eliminates the need for subsequent software-based color correction. This preliminary action resolves the contradiction by achieving accurate color temperature correction while maintaining high processing efficiency, as no additional processing time is required after the initial capture.
3Measurement precision
If manual color correcting gels are used, then color temperature adjustment is possible, but the process lacks automation and requires human intervention
Solution Approach 1:
The patent replaces manual mechanical systems with automated electronic systems. Instead of manually selecting and positioning color correcting gels, the system uses a color temperature meter to automatically measure environmental conditions, a microprocessor to calculate the appropriate RGB values, and an LED control unit to electronically adjust the light output. This complete automation chain eliminates human intervention while maintaining or improving color temperature accuracy, directly resolving the contradiction between measurement precision and extent of automation.
4Device complexity
If conventional lighting systems are used, then simple hardware is required, but color temperature adjustment capability is limited
Solution Approach 1:
The patent employs dynamic, adjustable LED light sources that can continuously vary their color temperature output across a wide range. Unlike conventional fixed-temperature light sources, the full-spectrum LED system can be electronically controlled to emit light at any color temperature within its operational range. This dynamic capability is managed by a microprocessor that receives input from a color temperature meter and automatically adjusts the LED output accordingly. The system maintains relative simplicity while achieving high adaptability, resolving the contradiction between device complexity and color temperature adjustment versatility.
