Umbrella Rod Assembly With Removable Light Band Diffuser
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing umbrella rods with integrated light strips are difficult to maintain, have large packaging volumes, and produce uneven lighting due to divergent light emission, resulting in an unattractive appearance.
Innovation Solution
A rod assembly with a hollow tube featuring a groove for receiving a lampshade, where the lampshade has a bottom surface capable of transmitting light and sides that do not, and the light strip emits light towards the sides, forming a uniform light band through the lampshade's divergence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If light strips are integrated with rods, then lighting function is achieved, but maintenance difficulty increases
Solution Approach 1:
The lighting system is segmented into separate components: the rod structure and the lampshade assembly with light strip are designed as detachable units. The lampshade can be removed from the rod, allowing the light strip to be accessed, replaced, or maintained independently without damaging the rod structure.
Solution Approach 2:
The light strip is extracted from direct integration with the rod and placed inside a removable lampshade assembly. This extraction allows the lighting component to be taken out for maintenance while preserving the rod structure.
2Illumination intensity
If light strips are integrated with rods, then lighting function is achieved, but packaging volume increases
Solution Approach 1:
The light strip is nested inside the lampshade, which itself can be nested within or alongside the rod structure during storage and packaging. This nested arrangement significantly reduces the overall packaging volume compared to separate packaging of all components.
3Area of stationary object
If light strip emits divergent light downward, then lighting range is wider, but lighting uniformity deteriorates
Solution Approach 1:
Different parts of the lampshade have different optical properties: the bottom surface is designed to be transparent or translucent for light transmission, while the side surfaces are opaque to control light direction. This local differentiation of optical qualities achieves both wide coverage and uniform lighting.
Solution Approach 2:
The lampshade acts as an intermediary between the light strip and the environment. It diffuses and redirects the divergent light from the light strip, transforming the uneven direct light into uniform ambient illumination while maintaining wide coverage.
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 allows for easy assembly and disassembly, reduces packaging volume, and enhances lighting uniformity and aesthetic appeal by diverging light spots into a uniform band, making it more convenient and visually appealing.
Implementation Method 1
the bottom surface of the lampshade is capable of transmitting lights
Implementation Method 2
Through the divergence of the lampshade, the spots of particles are diverged to form a whole light band

AI summary
A rod assembly for an umbrella comprises a rod; a lampshade assembly comprising a lampshade and a light strip disposed inside the lampshade. The rod has a groove for receiving and positioning the lampshade, the rod has an opening at a bottom of the groove facing downward. A bottom surface of the lampshade is capable of transmitting lights. One or more illuminants are disposed on the light strip facing one of the two sides of the lampshade. The rod assembly of the present invention is reasonable in structure and convenient to disassemble or assemble, thereby bringing great convenience for daily maintenance. Moreover, since the light strip faces one side of the lampshade to emit light, the single bead spots that are originally dense can be diverged to form a uniform light, achieving a better lighting effect.
