Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic simulated candles using LEDs lack enhanced light emission and realistic flame simulation, particularly in terms of light distribution and flicker control, which are essential for a convincing candle-like experience.
Innovation Solution
The design incorporates solid-state light sources with leads bent at a 90-degree angle to direct light horizontally, along with a range of electrical components such as dimmer units, flicker units, light sensors, motion sensors, and timers to enhance light output and simulate flickering effects, allowing for adjustable light intensity and timing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If traditional incandescent bulbs are used, then light output is high, but energy efficiency is low
Solution Approach 1:
The patent changes the fundamental operating parameters by transitioning from thermal radiation (incandescent) to electroluminescence (LED). The LED converts electrical energy directly to light with much higher efficiency, eliminating the need to heat a filament to incandescence. This parameter change resolves the contradiction by achieving both high light output and energy efficiency through a different physical mechanism.
2Use of energy by moving object
If LED light sources are used, then energy efficiency is improved, but light output is reduced
Solution Approach 1:
The patent merges multiple LED components into a single integrated assembly. By combining several LEDs with their respective lenses and mounting structures into one unified unit, the system achieves cumulative light output that competes with traditional bulbs while maintaining the energy efficiency of individual LEDs. The merged structure allows the weaknesses of individual low-output LEDs to be compensated by their collective strength.
3Illumination intensity
If LEDs are crammed into one unit, then light output is increased, but contact reliability deteriorates
Solution Approach 1:
The patent segments the LED assembly into modular components, each with its own mounting structure and electrical connections. Rather than cramming LEDs into a dense configuration where contacts are vulnerable, each LED is individually mounted and connected, isolating potential failure points. This segmentation maintains reliability while allowing multiple LEDs to work together for increased light output.
4Duration of action of stationary object
If solid-state light sources are used, then durability is improved, but realistic flame simulation deteriorates
Solution Approach 1:
The patent introduces dynamic control elements to simulate the natural variability of candle flames. By incorporating dimmer units and flicker units that randomly vary the light output intensity and timing, the system creates a dynamic light pattern that mimics the organic, unpredictable nature of real flames. This dynamic behavior compensates for the static, artificial appearance of solid-state lighting, achieving realistic flame simulation while maintaining LED durability.
5Illumination intensity
If lead bending is used to direct light horizontally, then light distribution is improved, but manufacturing complexity increases
Solution Approach 1:
The patent employs asymmetric lead bending at 90-degree angles to direct light horizontally rather than in the traditional vertical orientation. This asymmetric configuration optimizes light distribution for candle simulation applications where horizontal illumination is needed. While the bending adds a manufacturing step, the standardized 90-degree angle makes the process manageable and ensures consistent optical performance.
