Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a light guide body is made of optical materials such as acrylic polyester, polycarbonate, epoxy resin, and glass, then the light guide effect is improved, but the lighting requirement cannot be met and only decorative use is possible
Solution Approach 1:
The light guide body incorporates light guide plates with specific optical properties at strategic locations to enhance light distribution while maintaining the decorative aesthetic. This localized application of optical enhancement materials allows the bulb to meet lighting requirements without compromising the overall decorative design or requiring complete material replacement.
2Shape
If incandescent bulbs are used to achieve decorative effect, then the decorative effect is improved, but the service life is short and production cost is high
Solution Approach 1:
The invention introduces a light guide body as an intermediary component between the LED light source and the external environment. This light guide body, with its decorative surface features and optical properties, replicates the aesthetic qualities traditionally associated with incandescent bulbs while the LED technology provides the long service life and energy efficiency.
3Illumination intensity
If ordinary LED bulbs are used to meet lighting requirement, then the lighting requirement is met, but the decorative effect and production efficiency are reduced
Solution Approach 1:
The invention merges the lighting function and decorative function into a single integrated LED bulb design. The light guide body is molded as an integral part of the bulb structure, combining light transmission capabilities with decorative surface features. This integration eliminates the need for separate decorative components and simplifies the manufacturing process, thereby improving production efficiency while maintaining both lighting performance and aesthetic appeal.
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 design achieves improved light distribution and decorative effects, ensuring even and soft lighting while reducing production costs and extending bulb lifespan compared to incandescent and ordinary LED bulbs.
Implementation Method 1
A bottom of the light guide body is in contact with a luminous body, and depending on total internal reflection, light is transmitted in the light guide body
Implementation Method 2
a top of the light guide body is in a wavy shape and may have a light gathering effect, thereby resolving a problem of glowing at the top of the light guide body, and making the entire bulb body glow evenly and softly
