Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If flame light guides are used to simulate candle flame effect, then the lamp can be made safe (no fire risk) and flexible in design, but the flame simulation effect is limited to brightness control only and cannot achieve realistic flame lighting effect
Solution Approach 1:
The invention divides the light guide into multiple segments with different optical properties. The light guide includes a first light guide portion and a second light guide portion, each with different refractive indices and optical path designs. This segmentation allows different parts of the light guide to contribute differently to the flame simulation effect, enabling both safety and realistic flame appearance.
Solution Approach 2:
Different portions of the light guide are given different local optical qualities. The first light guide portion has a first refractive index and the second has a second refractive index, creating varying light transmission and diffusion characteristics in different regions. This local quality variation enables realistic flame simulation while maintaining overall safety.
2Extent of automation
If a single-chip microcomputer is used to control LED flame simulation, then timing and remote control functions are achieved, but the flame simulation effect remains limited and cannot simulate dynamic flame movement and brightness variation
Solution Approach 1:
The invention introduces dynamic control of the LED light source through the microcomputer, enabling the flame simulation to vary in brightness and intensity over time. The control module adjusts the LED output to simulate the natural fluctuations of a real flame, including flickering and color temperature changes, transforming the static light guide system into a dynamic flame simulation system.
Solution Approach 2:
The microcomputer controls the LED light source to emit light in periodic patterns that mimic natural flame behavior. By implementing periodic brightness variations and timing sequences, the system simulates the rhythmic flickering and movement of real flames, enhancing the realism of the flame simulation effect.
3Volume of moving object
If the size of flame light guide is limited, then the lamp structure remains compact, but the flame simulation effect cannot be enhanced beyond brightness control
Solution Approach 1:
The invention enhances the flame simulation effect by utilizing multiple dimensions of optical control rather than simply increasing light guide size. By varying the refractive indices, optical path lengths, and light emission angles in different spatial dimensions, the system achieves realistic flame simulation within a compact form factor, avoiding the need to increase overall lamp volume.
