Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional LED circuit is used to regulate color temperature, then color temperature adjustment is enabled, but the construction becomes complicated and cost increases
Solution Approach 1:
The circuit uses three separate LED lights with different color temperatures (2700K, 5000K, and a third LED) instead of a single complex adjustable LED circuit. Each LED light is independently controlled through diodes and switch connections, dividing the color temperature regulation function into discrete, manageable segments that are simpler to implement and control.
2Adaptability or versatility
If a conventional color temperature switching lamp with two lighting balls is used, then some color temperature switching is achieved, but the switching function is not regulated exactly and fabrication cost is greater
Solution Approach 1:
The circuit enables dynamic and precise control of color temperature by using a switch with multiple connections that can be adjusted to different positions. The switch dynamically connects different diodes and LED combinations based on the desired color temperature setting, allowing for exact regulation of five distinct color temperature values rather than fixed two-position switching.
Solution Approach 2:
The invention changes the operational parameters by using four diodes (D1-D4) in different conduction states depending on the switch position. Each diode configuration changes the effective circuit parameters, enabling precise control over the color temperature output by selectively activating different LED combinations with specific forward voltage characteristics.
3Ease of manufacture
If conventional lamps with fixed color temperature are used, then construction is simple, but versatility is limited and cannot satisfy market requirements
Solution Approach 1:
The circuit merges three separate LED lights with different color temperatures into a single lighting system. By combining these LEDs with diodes and a multi-position switch, the invention achieves multiple color temperature outputs (2700K, 3000K, 3500K, 4000K, 5000K) while maintaining relatively simple construction compared to conventional adjustable LED circuits.
