Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solar lamps are limited in their ability to emit light on the upper side of the transparent lampshade, as they typically have a cover or luminous assembly only on the sides, failing to meet new usage requirements for full lighting effects.
Innovation Solution
A transparent lampshade design with an upper light-transmitting portion and a downward installing recess for the solar luminous lamp assembly, allowing light to be emitted upwards, combined with a power storing-supplying assembly in a connecting through hole to reduce thickness and cost, and a sheet power storing-supplying module to decrease overall height and simplify production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a cover or luminous assembly is placed on the upper side of the transparent lampshade, then the lamp can emit light circumferentially, but it cannot emit light on the upper side of the lampshade
Solution Approach 1:
The lampshade is divided into multiple functional zones: an upper light-transmitting portion with a first outer convex annular portion and an upper convex annular portion, a lower light-transmitting portion, and a light diffusing cavity. This segmentation allows different regions to perform different functions - the upper portion transmits light upward while the lower portion transmits light downward, and the light diffusing cavity scatters light in multiple directions, achieving full-space illumination capability.
Solution Approach 2:
The patent introduces a vertical dimension for light transmission by creating an upper light-transmitting portion that allows light to pass through the upper side of the lampshade. The first outer convex annular portion and upper convex annular portion are positioned to transmit light upward, adding a vertical light emission dimension to the traditional horizontal circumferential lighting, thereby achieving three-dimensional full-space illumination.
2Reliability
If a traditional solar luminous lamp assembly is used, then the lamp structure is complete, but the overall thickness and production cost are increased
Solution Approach 1:
The power storing-supplying assembly is nested within the connecting through hole at the bottom of the lampshade, and the sheet power storing-supplying module is integrated into the solar luminous lamp assembly structure. This nesting approach allows the power storage components to be housed within existing structural spaces rather than adding external thickness, maintaining structural completeness while minimizing overall dimensions.
Solution Approach 2:
The patent employs a sheet power storing-supplying module that uses thin-film technology for power storage. This thin-film approach significantly reduces the thickness required for power storage functionality while maintaining the necessary electrical capacity, allowing the lamp to maintain a sleek, thin profile without compromising structural completeness or power supply reliability.
3Reliability
If a traditional power storing-supplying assembly is used, then the lamp functions properly, but the overall height and production complexity are increased
Solution Approach 1:
The sheet power storing-supplying module utilizes thin-film technology to create a flattened, low-profile power storage component. This thin-film design reduces the height dimension significantly compared to traditional bulky battery assemblies, while maintaining the necessary power storage capacity and electrical functionality for reliable lamp operation.
Solution Approach 2:
The power storing-supplying function is merged with the solar luminous lamp assembly structure itself. The sheet power storing-supplying module is integrated directly into the lamp assembly, combining multiple functions (power generation from solar panel, power storage, and light emission) into a single integrated unit, thereby reducing overall height and simplifying production.
4Illumination intensity
If light refracting patterns are added to the first outer convex annular portion, then the visual effect is improved, but the manufacturing complexity is increased
Solution Approach 1:
The first outer convex annular portion is designed with a curved, spherical-like surface that naturally refracts and disperses light. This curvature itself creates the light refracting effect without requiring additional complex patterns or coatings. The spherical geometry simplifies manufacturing compared to creating intricate angular patterns, while still achieving enhanced visual effects through natural light refraction and dispersion.
