Hair Strand Sample Holder With Magnetic Optic Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for positioning a hair strand for analysis are imprecise due to manual selection and positioning, which can impede the correct alignment and measurement of hair parameters using analysis devices.
Innovation Solution
A sample holder with a hinged design and removable optic attachment, featuring a groove for aligning and clamping the hair strand, and magnetic attachment for precise positioning of the analysis device's optic, allowing for easy and precise placement of the hair strand.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a hair clamp is mounted on the scanner to clamp a hair strand according to a desired position, then the hair strand can be held in position, but the measurement device scanner limits the possibility of moving the clamp and impedes the correct positioning thereof
Solution Approach 1:
The device is divided into two independent components: a movable sample holder for positioning the hair strand and a stationary scanner for measurement. The sample holder can be freely positioned and adjusted independently from the scanner, eliminating the constraint where the scanner limited clamp movement. This segmentation allows the sample holder to be optimally positioned for hair strand placement while the scanner remains in its measurement position.
Solution Approach 2:
A magnetic attachment system acts as an intermediary between the sample holder and the scanner. The magnetic attachment means with adjustable strength provides a flexible connection that allows easy positioning and attachment/detachment of the sample holder relative to the scanner, mediating between the need for stable holding and ease of positioning.
2Ease of manufacture
If manual selection and stretching of hair strand is performed between fingers, then a hair strand can be selected, but the positioning is unsatisfactory due to the lack of precision
Solution Approach 1:
The sample holder is prepared in advance with a V-groove specifically designed to receive and align the hair strand. The groove's geometry is pre-configured to automatically align multiple hair strands in parallel when placed within it, eliminating the need for manual stretching and alignment between fingers. This preliminary preparation of the holding structure ensures precise alignment upon placement.
Solution Approach 2:
The V-groove structure enables the hair strands to self-align when placed within the groove. The converging walls of the V-groove naturally guide and parallelize the hair strands without requiring manual manipulation. The system serves itself by using the geometric constraints of the groove to automatically achieve the desired parallel alignment of multiple hair strands.
