Solar Floatable Lamp Radial Light Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing floatable lamps suffer from poor illumination due to light being directed downwards, resulting in inadequate light refraction from the water surface, limiting their ability to illuminate a larger area effectively.
Innovation Solution
A solar-powered floatable lamp design featuring a transparent housing with a solar panel on top, a light emitting component on the side, and refracting ribs to distribute light radially, along with a processor and wireless communication for remote control, ensuring illumination both above and below the water surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the light emitting component is disposed on the lower part of the lamp component, then the structure is simple, but the illumination area is limited and illumination effect is poor
Solution Approach 1:
The patent transitions from downward light emission (single direction) to radial light emission through the transparent housing wall (multi-directional). The light emitting component emits light in all directions, and the transparent housing allows light to pass through its cylindrical wall, illuminating water in a radial pattern rather than just downward, thereby significantly expanding the illumination area.
Solution Approach 2:
The patent utilizes the transparency property of the housing material to enable light transmission. By making the housing transparent, light can pass through the housing wall to illuminate the surrounding water, transforming the housing from a simple enclosure to an active light transmission medium that expands illumination coverage.
2Ease of manufacture
If the light emitting component is disposed on the lower part of the lamp component, then the installation is simple, but the light refraction from water surface is insufficient
Solution Approach 1:
The patent changes the light emission direction from vertical (downward only) to radial (all directions through the cylindrical housing). This dimensional change in light propagation allows light to refract from the water surface in multiple directions, significantly enhancing the light refraction effect and visual impact.
Solution Approach 2:
The transparent housing material enables light to pass through and refract at the water surface, creating visual effects. The transparency allows light to interact with the water-air interface, producing refraction and reflection phenomena that enhance the decorative illumination effect.
3Use of energy by moving object
If the solar panel is disposed on top of the housing, then the solar energy absorption is maximized, but the light emission direction is limited
Solution Approach 1:
The patent separates the energy input direction (solar panel on top, absorbing vertical sunlight) from the light output direction (radial emission through the cylindrical housing). This dimensional separation allows the solar panel to maintain optimal solar exposure while the light emitting component illuminates in all radial directions, achieving both efficient energy absorption and versatile light distribution.
