Analyzer Placement Part Orientation and Measurement Path
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing analyzers are inconvenient for left- and right-handed users, require wrist flipping during urine sample placement, and have inefficiencies in photometric measurement, leading to potential hygiene issues and increased manufacturing costs due to unnecessary movement and wear on the photometric measurer.
Innovation Solution
An analyzer design that allows the analysis piece to be placed with reagent pads oriented in either direction, using a placement part that accommodates both orientations, and a photometric measurer that makes a one-way trip for measurement, with a correction mechanism to adjust for positional variations, reducing the need for extensive travel and maintaining parallelism with the carrier arm.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the placement part is arranged on the right-hand side to accommodate left-handed users, then ease of operation for left-handed users is improved, but the risk of urine spatter onto display panel and operation panel increases
Solution Approach 1:
The placement part is positioned asymmetrically on the left side of the analyzer body, which is the conventional arrangement that works well for right-handed users. This asymmetric placement avoids the need to move the test piece over the display panel and operation panel, thereby preventing urine spatter while maintaining ease of operation for the majority of users.
2Object-affected harmful factors
If the placement part is arranged on the left-hand side to prevent urine spatter, then hygiene cleanliness is improved, but ease of operation for left-handed users deteriorates
Solution Approach 1:
The placement part is designed with a universal layout that accommodates both right-handed and left-handed users effectively. By positioning the placement part on the left side with adequate space and proper orientation guidance, the design serves the majority of right-handed users while also being accessible to left-handed users, achieving multi-functionality in user accommodation.
3Measurement precision
If the photometric measurer makes a reciprocating trip for measurement, then measurement capability is improved, but manufacturing cost and device complexity increase due to unnecessary movement and wear
Solution Approach 1:
The photometric measurer is extracted from the reciprocating movement mechanism and repositioned to perform measurements in a single directional trip. This eliminates the unnecessary return movement, reducing mechanical wear, lowering manufacturing complexity, and decreasing operational costs while maintaining full measurement capability through optimized measurement path design.
4Manufacturing precision
If the test piece requires major pivoting movement during placement, then proper orientation can be achieved, but ease of operation deteriorates due to wrist flipping requirement
Solution Approach 1:
The placement part is designed with pre-oriented guidance features and adequate space that allow the test piece to be placed in the correct orientation directly, without requiring major pivoting or wrist flipping movements. The preliminary arrangement of the placement area guides the user through a simple placement motion, eliminating the need for complex wrist movements while ensuring proper orientation.
