Conventional candle-like lighting devices using halogen lamp modules face issues with high electricity costs and potential damage to the container due to insufficient heat energy when the wattage is low, and insufficient light intensity for variable ornamental designs.
Innovation Solution
A candle-like lighting device with a transparent decorative seat containing a low boiling point liquid, a through hole for a glowing member, and a circuit with a heat-generating body and light source components, including the option to use LED or halogen bulbs, to produce both heat and light, allowing for a colorful decorative effect with minimal current usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If halogen lamp module with low wattage is used, then electricity cost is reduced, but heat energy generated is insufficient to cause liquid flow
Solution Approach 1:
The heating function is segmented from the lighting function. A dedicated heat-generating body (resistive heating element) is separate from the LED light source, allowing independent optimization of heating efficiency without requiring high-wattage halogen lamps.
Solution Approach 2:
The patent replaces the thermal radiation heating mechanism of halogen lamps with direct resistive heating (Joule heating) through a heat-generating body, achieving more efficient heat transfer to the liquid with lower power consumption.
2Temperature
If halogen lamp module with high wattage is used, then heat energy is sufficient to cause liquid flow, but electricity cost increases and container may be damaged
Solution Approach 1:
A heat-resistant transparent plate is introduced as an intermediary between the heat-generating body and the container. This plate allows heat transmission to the liquid while protecting the container from direct exposure to high temperatures and potential damage.
Solution Approach 2:
The patent replaces indirect heating through thermal radiation (halogen lamp) with direct conductive/convective heating from a controlled heat-generating body, enabling precise temperature control that prevents container damage.
3Illumination intensity
If halogen lamp module is used, then light is produced, but light intensity is insufficient for variable ornamental design
Solution Approach 1:
The patent replaces halogen lamp illumination with LED (Light Emitting Diode) technology, which provides superior light intensity, color variability, and energy efficiency. LEDs can produce intense light with minimal power consumption and support variable ornamental designs through color changing capabilities.
Solution Approach 2:
The LED light source serves multiple functions: providing illumination, creating variable ornamental designs through color changes, and consuming minimal electricity. The single LED component replaces the dedicated lighting function of halogen lamps while adding color variability capabilities.
4Temperature
If halogen lamp module is used, then both light and heat are produced, but device complexity and electricity consumption increase
Solution Approach 1:
The patent segments the heating and lighting functions into separate components: a heat-generating body (resistive heating element) and an LED light source. This segmentation allows each component to be optimized independently and reduces overall device complexity compared to using a single high-wattage halogen lamp for both functions.
Solution Approach 2:
The patent replaces the complex halogen lamp system (requiring high wattage for dual heating and lighting) with simpler, dedicated components: a low-power heating element and an efficient LED, reducing overall system complexity and power requirements.
