Foam Ball Light-Emitting Skeleton for Low-Light Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Foam balls have low light transmittance, making it unsuitable to incorporate a light source, which limits their use at night or in low-light environments.
Innovation Solution
A foam ball with a light-emitting skeleton comprising a light source device and a light body, where the foam sphere covers the skeleton to expose a portion of the light body on its surface, enhancing visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a light source is disposed inside the foam material, then the ball can emit light, but the low light transmittance of foam material prevents effective light emission
Solution Approach 1:
The invention divides the ball structure into two separate parts: a foam sphere and a light-emitting skeleton. The light source is placed in the skeleton rather than embedded in the foam material, allowing the light-emitting components to be positioned where they can effectively emit light while the foam sphere serves as a separate protective and structural element.
Solution Approach 2:
The light-emitting skeleton acts as an intermediary structure between the light source and the external environment. It provides a framework that supports the light source device and light body, enabling effective light emission while the foam sphere covers and protects this skeleton without interfering with light transmission.
2Illumination intensity
If the light source is embedded in the foam material, then the ball can potentially emit light, but the manufacturing complexity and time increase significantly
Solution Approach 1:
By separating the light-emitting components from the foam sphere, the manufacturing process can proceed independently for each component. The foam sphere can be manufactured using conventional foam molding techniques, while the light-emitting skeleton can be assembled separately and then combined, significantly reducing overall manufacturing time and complexity.
Solution Approach 2:
The light-emitting skeleton is prepared in advance as a separate assembly with the light source device and light body already positioned. This preliminary preparation allows for efficient assembly with the foam sphere later, avoiding the need for complex embedded installations during the foam molding process.
3Strength
If the light body is completely covered by the foam sphere, then the structure is protected, but the light emission effect is reduced
Solution Approach 1:
The foam sphere is designed to cover only specific portions of the light-emitting skeleton, leaving certain areas exposed. This selective coverage provides protection where needed while maintaining light emission visibility in critical areas, optimizing both protective and illuminating functions.
Solution Approach 2:
Instead of completely covering the light-emitting skeleton, the foam sphere provides partial coverage. This partial action is sufficient to protect the structure while allowing the light emission function to remain effective, avoiding the excessive coverage that would block light.

AI summary
A foam ball having a light-emitting skeleton includes the light-emitting skeleton and a foam sphere. The light-emitting skeleton includes a light source device and a light body. The light body is in connection with the light source device, and the light body is configured to emit light. The foam sphere is formed by a foam material and covers the light-emitting skeleton to enable at least a portion of the light body to be disposed on a surface of the foam sphere.
