Specimen Inspection Injection Part with Stepped Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing specimen inspection apparatuses face challenges in accommodating specimen transporting apparatuses of various sizes, leading to clogging and contamination issues due to the fixed size of the injection part, which restricts the use of different sized pipette tips and complicates precise measurement in molecular biology applications.
Innovation Solution
The design incorporates a platform with an injection part having a larger diameter than the specimen transporting apparatus, featuring stepped parts, projection parts, and groove parts on the support surfaces and lower plate to securely accommodate and support the front end of the specimen transporting apparatus, preventing clogging and allowing for various sizes and shapes to be used.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the injection part has a fixed size, then the structure is simple, but it cannot accommodate specimen transporting apparatuses of various sizes
Solution Approach 1:
The injection part is divided into multiple stepped parts with different diameters, creating a segmented structure that can accommodate various sizes of specimen transporting apparatuses. Each step provides a different level of support for different tip sizes, transforming a single fixed-size opening into a multi-level adaptive structure.
Solution Approach 2:
The injection part transitions from a simple circular opening to a stepped cylindrical structure with multiple radial levels. This dimensional complexity allows the same injection part to interface with specimen transporting apparatuses of different diameters by providing multiple support surfaces at different radial distances from the central axis.
2Adaptability or versatility
If the injection part diameter is larger than the front end, then various sizes can be accommodated, but clogging may occur
Solution Approach 1:
Different regions of the injection part have different diameters, creating local variations in size. The stepped structure provides larger diameter regions for accommodating various tip sizes and smaller diameter regions near the introduction part to prevent clogging, optimizing both adaptability and flow characteristics in different locations.
Solution Approach 2:
The injection part employs parameter changes in diameter along its length, transitioning from a larger diameter at the outer region to a smaller diameter near the introduction part. This gradual parameter change allows accommodation of various tip sizes while preventing clogging by maintaining appropriate flow dimensions throughout the injection pathway.
3Measurement precision
If manual checking is required for safe insertion, then positioning precision can be verified, but operation time increases
Solution Approach 1:
The stepped parts provide self-aligning support surfaces that automatically guide the specimen transporting apparatus into the correct position during insertion. The geometric constraints of the stepped structure ensure proper positioning without requiring manual verification, making the system self-checking and eliminating time-consuming manual inspection steps.
