Container Rack With Recessed Support For Specimen Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing container racks for specimen analysis devices suffer from instability and increased cost due to complex structures and high dimensional accuracy requirements, leading to shaking and displacement issues during specimen analysis.
Innovation Solution
A container rack design featuring a holding portion with multiple holes for container heads and a leg portion that supports the containers from below, allowing for stable installation and restriction of movement within the specimen analysis device, reducing the need for precise dimensioning and simplifying the structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a support portion is added to support the bottom of the container, then the stability of the container is improved, but the number of parts increases and the structure becomes complicated
Solution Approach 1:
The patent merges the support function into the existing holding plate structure by forming a recessed portion that integrates both container holding and support functions. The holding plate simultaneously holds the container head portion and supports the body portion through the recessed structure, eliminating the need for separate support portions and reducing overall structural complexity.
Solution Approach 2:
The recessed portion of the holding plate creates a nested structure where the container body portion is received within the recessed area. This nesting approach allows the holding plate to provide support from within the existing structure rather than adding external support elements, maintaining compactness while improving stability.
2Manufacturing precision
If the support portion determines the height of the container, then the positioning accuracy is improved, but the manufacturing cost increases due to high dimensional accuracy requirements
Solution Approach 1:
The container rack is designed with pre-formed recessed portions and protruding portions that automatically guide container placement. The protruding portion of the container fits into the recessed portion, preliminarily establishing the correct position and height before the container is fully installed, thereby achieving accurate positioning without requiring high-precision manufacturing of all components.
Solution Approach 2:
The recessed portion acts as an intermediary structure that mediates between the holding plate and the container body. It provides a tolerance-absorbing interface that ensures proper container positioning and support height without requiring the holding plate itself to be manufactured with high dimensional accuracy, thus reducing manufacturing costs.
3Ease of manufacture
If the container rack structure is simplified, then the manufacturing cost is reduced, but the container may shake or displace in the specimen analysis device
Solution Approach 1:
Instead of adding support structures from below the holding plate, the invention inverts the support approach by creating a recessed portion in the holding plate that supports the container body from within the holding plate's structure. This inverted support method maintains structural simplicity while effectively preventing container shaking and displacement through the recessed-protruding fit mechanism.
