Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric candle flame apparatuses require a large number of lamp beads on both sides of the PCBA board to achieve uniform color and brightness, leading to increased costs and energy consumption.
Innovation Solution
The flame apparatus includes a PCBA board with a flame portion that allows light to pass through, with lamp beads arranged on one side face and color-toning layers on both side faces, along with a semi-transparent lamp head cover to ensure consistent light output and reduce the number of lamp beads needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If lamp beads are provided on both front and back sides of the PCBA board to achieve uniform color and brightness, then the light output consistency is improved, but the number of lamp beads increases exponentially, leading to increased cost and energy consumption
Solution Approach 1:
A color-toning layer is introduced as an intermediary component between the lamp beads and the external environment. This layer is applied only on the front side of the PCBA board to adjust the color and brightness of light emitted from that side, eliminating the need to install lamp beads on both sides. The color-toning layer acts as a mediator that achieves visual consistency without requiring symmetric hardware configuration.
Solution Approach 2:
The patent applies asymmetry by placing lamp beads only on one side of the PCBA board while using a color-toning layer on the front side to achieve uniform appearance. This asymmetric configuration replaces the traditional symmetric approach of installing identical components on both sides, thereby reducing the total number of lamp beads while maintaining light output consistency.
2Reliability
If lamp beads are provided on both front and back sides of the PCBA board, then the flame simulation effect is improved, but the energy consumption increases due to the larger number of lamp beads
Solution Approach 1:
The color-toning layer serves as a mediator that enhances the flame simulation effect by adjusting the color temperature and brightness distribution of the light emitted from the single-sided lamp bead configuration. This intermediary component allows realistic flame simulation without requiring doubled energy input from additional lamp beads.
Solution Approach 2:
The patent utilizes color changes through the color-toning layer to achieve realistic flame simulation. The layer modifies the spectral characteristics of the light emitted by the lamp beads, creating the characteristic warm, flickering appearance of a flame without requiring additional light sources, thereby reducing overall energy consumption.
3Stability of the object's composition
If lamp beads are provided on both front and back sides of the PCBA board, then the light distribution uniformity is improved, but the manufacturing cost increases due to the exponential increase in lamp bead quantity
Solution Approach 1:
The color-toning layer acts as a manufacturing-friendly intermediary that achieves light distribution uniformity through a single-sided application process. This approach eliminates the complex dual-sided assembly required by traditional methods, reducing manufacturing steps, assembly time, and material costs while maintaining consistent light output.
Solution Approach 2:
The patent extracts the color adjustment function from the lamp bead assembly itself and separates it into a distinct color-toning layer component. This extraction allows the lamp beads to focus solely on light generation while the color-toning layer handles color and brightness uniformity, simplifying the overall manufacturing process and reducing the need for expensive, precision-matched dual-sided lamp bead installations.
