Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If multiple circuit boards are used to provide flame effect visible from all viewing angles, then the flame simulation quality is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent transitions from a two-dimensional surface mounting approach to a three-dimensional through-hole mounting approach. LEDs are mounted inside through-holes that extend between two opposing faces of a single circuit board, allowing light to emerge from both faces. This dimensional change enables full-view flame simulation from all angles while using only one circuit board, resolving the contradiction between visibility quality and device complexity.
2Illumination intensity
If multiple circuit boards are used to achieve omnidirectional flame visibility, then the flame simulation quality is improved, but the manufacturing cost increases
Solution Approach 1:
The patent merges the functions of multiple circuit boards into a single circuit board by implementing through-holes that allow LEDs to be visible from both faces. This consolidation reduces the number of components, simplifies assembly procedures, and lowers manufacturing costs while maintaining the omnidirectional flame visibility effect.
3Device complexity
If LEDs are mounted on a single circuit board with through-holes, then the device complexity is reduced, but the flame effect visibility from all angles may be compromised
Solution Approach 1:
By utilizing the third dimension (through the thickness of the circuit board), the patent enables LEDs to be visible from both front and back faces simultaneously. This dimensional approach ensures that the flame effect is visible from all viewing angles while using only a single circuit board, thus maintaining both simplicity and visual quality.
4Adaptability or versatility
If additional circuit boards are used for LED driver integration, then the functionality is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent combines the LED driver functionality with the existing single circuit board that already contains the through-hole mounted LEDs. This integration eliminates the need for separate driver circuit boards, reducing overall device complexity and manufacturing costs while maintaining full functionality for flickering flame simulation.
