Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic analyzing devices face challenges in maintaining consistent light quantity across multiple photometry units due to variations among light emitting units, requiring time-consuming adjustments and potential unit deterioration, which can lead to unusable slots.
Innovation Solution
The device employs a rotating table with a single light radiating unit and multiple light receiving units, allowing the emission direction of light to be changed for each reaction cuvette, ensuring consistent light quantity without the need for individual adjustments at each slot.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple photometry units are provided (one per slot), then each slot can perform independent photometry, but light quantity variation requires adjustment of each light emitting unit individually
Solution Approach 1:
The patent combines multiple light emitting units into a single light emitting unit that can change its emission direction. This single unit serves all slots sequentially, eliminating the need for multiple independent light emitting units and their individual adjustments, thus resolving the contradiction between photometry capacity and adjustment complexity
Solution Approach 2:
The light emitting unit is made dynamic by enabling it to change its emission direction. This dynamic capability allows one light emitting unit to serve multiple slots at different positions, replacing the static configuration of multiple fixed light emitting units, thereby reducing adjustment complexity while maintaining productivity
2Reliability
If multiple light emitting units are provided, then each slot has dedicated light source, but light quantity variation among units requires time-consuming adjustments
Solution Approach 1:
Multiple light emitting units are merged into a single light emitting unit with variable emission direction. This single unit is adjusted once to emit light of consistent quantity to all slots sequentially, eliminating the need for repeated adjustments at each slot and reducing total adjustment time while maintaining photometry consistency
Solution Approach 2:
The single light emitting unit is designed to perform multiple functions by emitting light to different slots at different positions. This universal unit replaces multiple specialized units, requiring only one adjustment procedure rather than multiple separate adjustments, thus reducing time loss while ensuring consistent light quantity across all slots
3Productivity
If photometry units are provided for each slot, then each slot can operate independently, but light emitting units may deteriorate and become unusable
Solution Approach 1:
Multiple light emitting units are merged into one, reducing the total number of light sources that can deteriorate. This single light emitting unit serves all slots, so if it deteriorates, the entire system stops rather than having multiple independent failure points, but the probability of failure is reduced due to fewer total units, and maintenance is simplified
Solution Approach 2:
The single light emitting unit is positioned and oriented to create equivalent light emission conditions for all slots sequentially. This copying of the emission function to different positions ensures that each slot receives consistent light quantity, maintaining analysis throughput while improving reliability through reduced light source count
