Luminous Ball With Detachable Light Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing balls on the market are not luminous, limiting their use to well-lit environments, and often have issues with light transmittance, battery replacement, and user comfort due to hard shells and poor hand feel.
Innovation Solution
A luminous ball design featuring a light-transmittance inner airbag, an accommodating shell, a light-transmittance outer surface layer, a detachable light-emitting assembly, and a cover body that allows for easy battery replacement and soft light emission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a lamp is provided on the ball to enable use in low-light environments, then the ball becomes luminous and visible in dark conditions, but the shell may block light transmission or emit strong light that directly hits the user's eyes
Solution Approach 1:
The patent introduces a light-transmittance outer surface layer as an intermediary between the light source and the user's eyes. This layer diffuses the light emitted by the lamp, preventing direct exposure to strong light while still allowing the ball to be visible in low-light environments. The outer surface layer acts as a mediator that transforms direct light into scattered, softer light.
2Strength
If the shell is made hard to provide structural strength, then the ball maintains its shape and durability, but the hand feel is poor and friction force is low causing the ball to slip
Solution Approach 1:
The patent employs a composite structure combining an inner airbag for structural support with an outer surface layer made of soft material. This composite design allows the ball to maintain structural integrity through the inner airbag while providing comfortable hand feel and adequate friction through the soft outer layer, resolving the contradiction between hardness and grip.
3Adaptability or versatility
If the light-emitting assembly is integrated into the ball to enable luminous function, then the ball can be used in low-light conditions, but the battery and lamp become difficult to replace requiring special tools
Solution Approach 1:
The patent segments the light-emitting assembly into a separate, detachable module that can be easily removed from the ball. This modular design allows the battery and lamp to be replaced without requiring disassembly of the entire ball structure or special tools. Users can simply detach the light-emitting assembly and replace the components, significantly improving ease of repair while maintaining low-light adaptability.
4Shape
If the outer surface is made smooth to improve aesthetics, then the ball looks better, but the friction force is low causing it to fall off hands easily
Solution Approach 1:
The patent applies different surface qualities to different regions of the outer surface layer. The outer surface is designed with localized texture patterns that provide friction where needed (on the surface layer) while maintaining an overall aesthetically pleasing appearance. This local quality variation allows the surface to simultaneously achieve good looks and adequate grip without compromising either aspect.
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 enables the ball to emit soft light, facilitating use in low-light conditions, while also being easy to assemble and disassemble, and providing a comfortable grip due to a softer outer surface.
Implementation Method 1
a light-transmittance inner airbag, wherein the light-transmittance inner airbag defines an inflation space and a second opening communicated to the inflation space, and the light-transmittance inner airbag is made of polyvinyl chloride (PVC) or rubber; a light-transmittance outer surface layer, wherein the light-transmittance outer surface layer is wrapped around an outer surface of the light-transmittance inner airbag

AI summary
A luminous ball includes a light-transmittance inner airbag, a light-transmittance outer surface layer, a light-emitting assembly and a cover body. The light-transmittance inner airbag defines an inflation space. An accommodating slot is provided in the light-transmittance inner airbag. The outer wall of the accommodating slot extending into the inflatable space from the outside. The light-transmittance outer surface layer is wrapped around an outer surface of the light-transmittance inner airbag. The light-transmittance outer surface layer is provided with a first opening. The light-emitting assembly is detachably inserted into the accommodating slot. The cover body is in detachable threaded connection to an inner wall of the accommodating slot and covers the accommodating slot to limit the light-emitting assembly in the accommodating slot. The cover body is in detachable to the accommodating slot and covers the accommodating slot to limit the light-emitting assembly in the accommodating slot.
