Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing egg identification systems face challenges in accurately distinguishing between viable and non-viable eggs, particularly due to interference from stray light, which limits their ability to discriminate among live and non-live eggs, especially rotted eggs.
Innovation Solution
An egg identification system incorporating a light controlling assembly with an absorbing layer that absorbs greater than 90% of reflected electromagnetic radiation, positioned between the emitter and detector assemblies, to minimize interfering light and enhance signal accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional candling systems use simple light sources and detectors, then the device complexity is low, but the measurement precision for distinguishing live and non-live eggs is insufficient due to stray light interference
Solution Approach 1:
The patent introduces a light controlling assembly as an intermediary component between the light source and detector. This assembly includes light shields and absorbing materials that mediate the light path, blocking stray light while allowing transmitted light from eggs to reach the detector, thereby improving measurement precision without requiring complete system redesign
Solution Approach 2:
The patent extracts and eliminates the harmful stray light components from the detection system by using light shields and absorbing materials. The light controlling assembly selectively removes interfering light paths while preserving the useful transmitted light signal, improving the signal-to-noise ratio for egg viability detection
2Measurement precision
If the light controlling assembly uses highly absorbing materials to block stray light, then the measurement precision improves, but the use of energy by the system increases due to additional light absorption and heat generation
Solution Approach 1:
The patent converts the potentially harmful stray light into a beneficial signal by using absorbing materials that convert stray light energy into heat, which is then dissipated. The light shields are positioned to redirect useful transmitted light away from the absorbing materials, ensuring that only harmful stray light is converted to heat while preserving the detection signal
Solution Approach 2:
The light controlling assembly uses locally optimized absorbing materials and light shields positioned at specific locations where stray light is most problematic. The absorbing properties are concentrated in strategic areas rather than uniformly distributed, minimizing overall energy consumption while maintaining measurement precision in critical detection zones
