Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fan is used to blow the red silk ribbon in traditional flame lamp assemblies, then the flame simulation effect is achieved, but noise is generated and power consumption increases
Solution Approach 1:
The patent replaces the mechanical fan system with an LED-based optical system. Instead of using a fan to physically move a silk ribbon, the invention uses LED bulbs arranged in a specific pattern on a cylindrical circuit board to directly generate the flame-like light effect, eliminating mechanical moving parts and the associated noise and power consumption.
Solution Approach 2:
The patent creates a visual copy of flame behavior through LED lighting patterns. The LED bulbs are controlled to blink and change intensity in sequences that replicate the natural flickering and movement of real flames, achieving the flame simulation effect without physical flame or mechanical movement.

4Reliability
If multiple shift registers are used to convert time series data to parallel signals in LED flame simulation, then flame effect is achieved, but the process becomes complex and costly
Solution Approach 1:
The patent merges the data conversion function into a single integrated control circuit board that directly controls the LED circuit board. Instead of using multiple separate shift registers for data conversion, the invention integrates the control logic and driving circuitry into one unified system, significantly simplifying the overall circuit architecture.
Solution Approach 2:
The control circuit board serves multiple functions: it generates the flame simulation patterns, controls the LED timing and brightness, and directly drives the LED circuit board. This multi-functional design eliminates the need for separate dedicated components for each function, reducing overall system complexity.

AI summary
A 360-degree LED light-emitting flame lamp capable of simulating a flame shaking effect comprises a lampshade (1) and a light source (2) disposed in the lampshade. The light source comprises a lamp housing (201) and a base (202) disposed at one end of the lamp housing. A lamp holder (203) is disposed on the base. A lamp panel support (204) is disposed in the lamp housing. The outer surface of the lamp panel support is covered with a columnar or polyhedral LED circuit board (205). LED lamp beads (206) are distributed on the LED circuit board. A control circuit board (207) and a driving power source (208) are sequentially and electrically connected between the LED circuit board and the lamp holder. The control circuit board outputs PWM signals according to a certain time sequence so as to control the LED lamp beads to be turned on and turned off and to flicker, and the driving power source drives the control circuit board and the LED circuit board to work. The flame lamp achieves a flame jumping effect in various directions by 360 degrees at the outer portion of the lampshade, and the flame effect is formed by means of light emission of the light source, so as to achieve the objectives of being free of noise and reducing power consumption and making the flame lamp suitable for indoor and outdoor use.
