Transverse Biochemical Analyzer Delivery System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing biochemical analyzers have insufficient sample holder buffering capacity due to their vertical delivery model, limiting the number of samples that can be processed and requiring lengthening of the analyzer to increase capacity, which occupies more space.
Innovation Solution
A transverse biochemical analyzer delivery system with parallel sample feeding, advancing, recovery tracks, and perpendicular to-be-tested, emergency, and return sub-tracks, allowing for increased sample holder buffering without lengthening the analyzer, with independent sub-tracks for emergency samples to prevent interference with regular testing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a vertical delivery model with tracks arrayed along the length direction is used, then the biochemical analyzer structure is simple, but the sample holder buffering capability is insufficient and only two sample holders can be buffered
Solution Approach 1:
The patent transitions from a vertical delivery model (tracks arrayed along the length direction) to a transverse delivery model (tracks arrayed along the width direction). This dimensional change allows multiple sub-tracks to be arranged side-by-side, significantly increasing sample holder buffering capability without extending the analyzer length. The transverse arrangement enables parallel processing paths while maintaining a compact footprint.
Solution Approach 2:
The delivery system is segmented into multiple independent sub-tracks (to-be-tested sub-track, emergency sub-track, return sub-track) that operate in parallel. Each sub-track can handle sample holders independently, allowing the system to buffer multiple sample holders simultaneously. This segmentation transforms a single-track vertical system into a multi-track transverse system, resolving the contradiction between buffering capacity and device length.
2Quantity of substance
If the biochemical analyzer is lengthened to increase buffering capability, then the sample holder buffering capability increases, but the space occupied by the analyzer increases
Solution Approach 1:
By switching from vertical to transverse track arrangement, the patent utilizes the width dimension instead of the length dimension to accommodate multiple buffering positions. This allows the analyzer to achieve high buffering capacity while maintaining a compact overall footprint, directly addressing the contradiction between buffering capacity and occupied space.
3Adaptability or versatility
If emergency samples are processed through the same track as regular samples, then the track structure is simple, but the delivery of emergency samples impacts buffering of sample holders on the to-be-tested sub-track
Solution Approach 1:
The patent divides the delivery system into separate sub-tracks, including a dedicated emergency sub-track that is independent from the to-be-tested sub-track. This segmentation allows emergency samples to be processed without interfering with the buffering and testing of regular samples. The independent emergency sub-track ensures that normal detection operations maintain stability and reliability while accommodating emergency processing needs.

AI summary
A biochemical analyzer delivery system, comprising a sample feeding track (42), an advancing track (43), a recovery track (44), at least one to-be-tested sub-track (45), at least one emergency sub-track (46) and at least one return sub-track (47); the sample feeding track (42), the advancing track (43) and the recovery track (44) are parallel to each other; the to-be-tested sub-track (45), the emergency sub-track (46) and the return sub-track (47) are disposed between and perpendicular to the sample feeding track (42) and the advancing track (43), an emergency sample may enter the emergency sub-track via the advancing track (43), and then enters the sample feeding track for sample suction. The track-based delivery system can be horizontally disposed in a biochemical analyzer, and can be butt-jointed with a vertical track in the biochemical analyzer, thereby greatly increasing the buffer amount of sample holders without increasing the length of the biochemical analyzer.
