Elastic Shaft Flame Piece for Flickering Imitation Lamp
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional imitation candle lamps have a stiff and un lifelike faux flame effect due to limited swing amplitude of the flame piece supported by a wire, resulting in an inadequate imitation of an actual candle flame.
Innovation Solution
An imitation flame lamp head with a mounting base, a drive device, an elastic shaft, and an illuminant, where the elastic shaft is connected to the flame piece and driven by the motor to swing randomly, mimicking the flickering and movement of a candle flame, enhancing the realism of the flame effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the flame piece is supported by a wire, then the structure is simple and stable, but the swing amplitude is limited and the imitation effect is stiff
Solution Approach 1:
The patent replaces the static wire support with a dynamic elastic shaft that can bend and flex. The elastic shaft is driven by a motor to rotate intermittently, creating random swinging motions of the flame piece that mimic real candle flame behavior under breeze, thereby resolving the contradiction between structural stability and swing amplitude.
Solution Approach 2:
The patent changes the physical parameter of the support from rigid (wire) to elastic (shaft). The elastic shaft can deform under motor-driven rotation, allowing the flame piece to achieve larger swing amplitudes while maintaining structural integrity through the elastic properties of the shaft material.
2Ease of operation
If the flame piece swings with large amplitude, then the imitation effect is lifelike, but the support structure becomes complex
Solution Approach 1:
The patent applies local quality by making only the support shaft elastic while keeping other components simple. The elastic shaft is positioned specifically at the connection point between the motor and flame piece, providing the necessary flexibility and swing amplitude without requiring complex mechanisms throughout the entire structure.
Solution Approach 2:
The elastic shaft acts as an intermediary between the motor and the flame piece. It translates the motor's intermittent rotation into random swinging motions, mediating the energy transfer while simplifying the overall structure compared to complex mechanical linkage systems that would otherwise be needed to achieve similar effects.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution achieves a more lifelike and realistic flickering flame effect by varying the position and size of the light spot, resembling an actual candle flame under a breeze, with improved applicability and aesthetics through the use of a multi-leaf flame piece and elastic shaft.
Implementation Method 1
the flame piece will be swung randomly by the action of the elastic restoring force of the elastic shaft
Implementation Method 2
the illuminant emits lights on the flame piece which swings randomly to form a light spot

AI summary
An imitation flame lamp head includes a mounting base, a drive device, an elastic shaft, a flame piece and an illuminant. The drive device is fixed in the mounting base, an upper end of the elastic shaft is fixed to a lower end of the flame piece, the flame piece is protruded outwards the mounting base, the illuminant is configured inside the mounting base to emit lights to a side of the flame piece, and the elastic shaft is driven by the drive device to actuate the flame piece to swing. The lamp displays flaming and flickering effect of faux flame to achieve an excellent imitation effect.
