Solution Overview
Problem
Conventional metal pet ID tags are ineffective in low-light conditions and lack reflective capabilities, posing identification challenges in darkness and potentially causing injury due to sharp edges.
Innovation Solution
A circular, injection-molded hard plastic pet ID tag with electro photocell material that glows in darkness and features a glossy aluminum reflective tape for visibility, eliminating sharp edges and enhancing readability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If conventional metal ID tags are used, then the tag provides identification through written description, but the tag cannot glow in the dark or reflect light, making identification ineffective in low-light conditions
Solution Approach 1:
The patent combines multiple materials with different properties: electro photocell material for glow-in-the-dark capability, glossy aluminum reflective tape for light reflection, and hard plastic for structural integrity. This composite construction enables the tag to provide identification under various lighting conditions, resolving the contradiction between visibility in darkness and identification reliability.
Solution Approach 2:
The electro photocell material undergoes a change in optical properties by absorbing light energy and re-emitting it as visible glow in darkness. This color/brightness change enables the tag to be visible in low-light conditions while maintaining its identification function, directly addressing the visibility-reliability contradiction.
2Object-affected harmful factors
If conventional metal ID tags are used, then the tag provides identification, but the sharp edges can cause injury
Solution Approach 1:
The patent employs a circular design with smooth edges throughout, eliminating sharp corners and edges that could cause injury. The circular shape maintains structural integrity and durability while removing harmful sharp features, directly resolving the contradiction between safety and strength.
3Illumination intensity
If electro photocell material is used for glow in the dark, then the tag provides identification in total darkness, but the tag requires light exposure to charge the cells
Solution Approach 1:
The electro photocell material performs preliminary energy storage by absorbing light during daytime or illuminated periods. This pre-charging action enables the tag to glow in darkness without requiring active power sources, resolving the contradiction between darkness visibility and energy requirements through advance energy accumulation.
