Luminous Ball Removable Insulator for Seamless Battery Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing luminous balls for baseball and softball require battery replacement, which alters the ball's appearance and texture, making them different from regular balls.
Innovation Solution
A luminous ball design featuring a light-transmissive sphere with a removable electrical insulating unit, allowing the light-emitting unit to be powered only when needed, and a covering that mimics the appearance and texture of regular balls, eliminating the need for a battery-size cut for replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a battery replacement design is implemented in the luminous ball, then the ball can be reused after battery depletion, but the appearance and texture of the ball are changed due to battery-size cuts on the covering
Solution Approach 1:
The patent extracts the battery replacement function from the external covering and relocates it to the internal structure. The battery compartment is integrated within the sphere, allowing battery access through the light-emitting opening without cutting the covering, thus preserving the ball's appearance while enabling battery replacement.
Solution Approach 2:
The battery compartment is nested within the sphere's internal structure, with the battery housed inside a dedicated compartment that is accessible through the light-emitting opening. This nested design allows the battery to be replaced without affecting the external covering's integrity or appearance.
2Illumination intensity
If the electrical insulating unit is removed to enable lighting, then the light-emitting unit can be powered, but the electrical connection between the light-emitting unit and power unit must be reliably established
Solution Approach 1:
The conductive adhesive is pre-applied to the contact surfaces before the electrical insulating unit is removed. This preliminary preparation ensures that when the insulating unit is removed, the electrical connection is immediately established without requiring additional assembly steps, thus maintaining reliability while enabling light emission.
Solution Approach 2:
The conductive adhesive acts as an intermediary material between the battery terminals and the light-emitting unit contacts. It provides a reliable electrical connection path while allowing for simple assembly and disassembly of the electrical insulating unit, thus balancing connection reliability with ease of operation.

AI summary
A luminous ball is provided, including a sphere, at least one covering spliced to wrap the sphere, at least one seam formed on an edge of the covering, a plurality of thread apertures disposed at two sides of the seam, at least one thread penetrating the plurality of thread apertures to stitch the edge of the covering between the two sides of the seam, and a light-emitting device disposed in the sphere. The light-emitting device includes a light-emitting unit, a power unit, and an electrical insulating unit breaking an electrical connection between the light-emitting unit and the power unit. The electrical insulating unit is removable. The electrical connection between the light-emitting unit and the power unit is provided when the electrical insulating unit is removed such that lights emitted by the light-emitting unit penetrate the sphere and are visible through the seam and the thread apertures.
