Existing LED candle lights fail to simulate the effect of a swinging flame and flickering dimming of a burning candle, resulting in low simulation and amusement value, which does not meet the increasing demand and usage requirements of users.
Innovation Solution
An LED candle light design featuring a battery pack, power control board, coil, mounting frame, LED light, flame cover, pendulum, and magnet, where the battery pack provides unregulated voltage to the coil, generating an irregular magnetic field that causes the pendulum to swing, simulating a candle flame's movement, and includes features like a silicone flame cover, thermistor, and multiple LED lights for enhanced realism and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If traditional LED candle lights are used, then energy saving and environmental friendliness are achieved, but the simulation effect of candle flame swinging and flickering is insufficient
Solution Approach 1:
The patent applies the dynamics principle by introducing a pendulum mechanism that can swing freely under magnetic field influence. The pendulum's irregular swinging motion dynamically drives the flame cover to move, creating a realistic candle flame effect that is impossible with static LED designs. This dynamic element resolves the contradiction by adding mechanical motion to achieve high simulation effect while maintaining LED energy efficiency.
Solution Approach 2:
The patent utilizes mechanical vibration through the pendulum's oscillating motion driven by electromagnetic repulsion. The coil generates an alternating magnetic field that causes the pendulum to vibrate and swing irregularly, which in turn creates the flickering and swinging effect of the flame cover. This mechanical vibration principle directly addresses the simulation effect deficiency while keeping the system energy-efficient.
Solution Approach 3:
The patent replaces the traditional mechanical swinging mechanism with an electromagnetic field-based system. Instead of using motors or mechanical linkages to swing the flame cover, the invention uses a coil to generate magnetic fields that repel a magnet on the pendulum, causing it to swing. This substitution eliminates complex mechanical drive systems while achieving the desired flickering and swinging effects, thereby maintaining energy efficiency.
2Manufacturing precision
If a pendulum mechanism is added to simulate flame swinging, then the simulation effect is improved, but the device complexity increases
Solution Approach 1:
The patent applies the universality principle by designing the pendulum to serve multiple functions simultaneously: it acts as both the swinging element to create flame motion and as the mounting structure for the magnet that interacts with the coil. The flame cover is also multi-functional, serving as both a protective enclosure and the visual element that displays the flame effect. This reduces overall system complexity by combining functions into fewer components.
Solution Approach 2:
The patent uses the magnetic field as an intermediary between the coil and the pendulum, eliminating the need for direct mechanical connections or complex drive mechanisms. The electromagnetic interaction allows the coil to control the pendulum's motion without physical contact, simplifying the mechanical structure. The magnet on the pendulum acts as the intermediary that converts electrical energy from the coil into mechanical swinging motion.
