Luminous Flying Disc Radial Light Guide for Eye Irritation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional luminous flying discs emit light directly outward, potentially irritating or damaging human eyes, and their structures are prone to damage during collisions.
Innovation Solution
The design incorporates an inner light guide strip that radiates light radially towards the center of the disc, using an annular light guide ring to scatter light uniformly, and features a soft material for the light guide strip to prevent damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If LED lamp beads are disposed along the edge of the flying disc to achieve better lighting effects, then the lighting effect is improved, but the light directly illuminates human eyes causing irritation or damage
Solution Approach 1:
The patent introduces an intermediary light guide structure between the LED lamp beads and the external environment. The light guide strip and light guide ring transmit and scatter the light from the LED beads, preventing direct emission toward human eyes while maintaining lighting effects. This intermediary component redirects the light path to eliminate eye irritation.
Solution Approach 2:
The patent applies different material properties to different parts of the light guide structure. The light guide strip and light guide ring are made of translucent materials with specific light transmission characteristics that enable controlled light scattering. This local quality differentiation allows the structure to redirect light away from direct eye exposure while preserving overall illumination.
2Ease of manufacture
If the outer ring is formed through one-shot injection molding and made of the same hard material as the housing, then the manufacturing process is simplified, but the structure is easy to be damaged during landing or collision
Solution Approach 1:
The patent employs composite material construction where the outer ring is made of a soft material layer over a hard substrate. This composite structure combines the manufacturing simplicity of injection molding with the durability of reinforced materials, creating an outer ring that resists damage during landing or collision while maintaining ease of manufacture.
Solution Approach 2:
The patent incorporates a soft material layer in the outer ring structure beforehand to provide cushioning protection. This pre-built cushioning layer absorbs impact during landing or collision, preventing damage to the internal components and structure, while the overall design remains compatible with standard injection molding processes.
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 radial light emission reduces eye irritation and enhances structural durability by scattering light uniformly and using soft materials for the light guide strip.
Implementation Method 1
light emitted by the light guide strip radiates toward an inner side of a center of the flying disc in a radial direction
Implementation Method 2
the light emitted by the lamp beads directly penetrates through a transparent or translucent housing to be emitted outward
