Solution Overview
Problem
Existing lighting toys that rely on battery power face issues such as light emission failure due to battery exhaustion and the associated costs and labor for battery replacement.
Innovation Solution
A lighting toy design that utilizes a light guide body with a light collecting portion, reflection portion, and lighting portion to harness external light sources, eliminating the need for battery power.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a battery-powered light source is used in the lighting toy, then the toy can emit light independently, but the light source may fail due to battery exhaustion and requires replacement incurring cost and labor
Solution Approach 1:
The patent extracts the battery component from the lighting toy system, replacing it with an external light guide body that channels light from outside sources. This removes the battery-related reliability issues and replacement complexity while maintaining the light emission function.
Solution Approach 2:
The patent introduces a light guide body as an intermediary component between external light sources and the toy's lighting portions. This mediator channels and directs light without requiring internal power generation, eliminating battery dependency while preserving illumination functionality.
2Duration of action of moving object
If a battery-powered light source is used in the lighting toy, then the toy can provide continuous illumination, but ongoing maintenance costs and labor for battery replacement are required
Solution Approach 1:
By removing the battery system entirely and replacing it with passive light guiding components, the patent eliminates the need for periodic battery replacements. The illumination duration becomes limited only by the availability of external light sources rather than battery capacity.
Solution Approach 2:
The lighting toy becomes self-sufficient by using externally available light sources (such as ambient room lighting or sunlight) without requiring internal power storage. The system automatically utilizes available light without manual intervention for battery changes.
3Illumination intensity
If a light guide body with reflection portion is used, then light can be effectively directed to the lighting portion, but the device structure becomes more complex
Solution Approach 1:
The patent merges the light guide body, reflection portion, and lighting portions into an integrated structure. The reflection portion is incorporated as an integral component of the light guide body, simplifying manufacturing and assembly while maintaining effective light direction and illumination intensity.
