Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cholesterol measurement devices using the color development method face issues with LED light intensity degradation, loss of check strips, deviations in gray values, difficulty in confirming LED light intensity, contamination of measurement units, and the inconvenience of separate printer devices.
Innovation Solution
A cholesterol measurement device with a light-intensity check member integrated into the measuring instrument body, a detachable strip fixation unit for easy cleaning, and a portable printer for direct measurement value output, ensuring accurate and reliable measurements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate check strip is provided by each manufacturer, then the LED light intensity can be checked, but the check strip is lost during use and requires separate storage
Solution Approach 1:
The check strip is integrated into the measuring instrument body as a built-in component. The check strip is positioned in a check strip positioning groove within the instrument body, eliminating the need for separate check strips and their associated management issues. This merging resolves the contradiction by maintaining the LED light intensity check function while eliminating the loss and storage problems of separate check strips.
2Productivity
If a check strip is formed of injection molding product, then the check strip can be mass-produced, but a deviation in gray value between the check strips occurs
Solution Approach 1:
The check strip is integrated into the measuring instrument body as a built-in component. The check strip is positioned in a check strip positioning groove within the instrument body, eliminating the need for separate check strips and their associated management issues. This merging resolves the contradiction by maintaining the LED light intensity check function while eliminating the loss and storage problems of separate check strips.
3Ease of operation
If the specimen is dropped into the specimen inlet of the measurement strip, then the cholesterol measurement can be performed, but the specimen overflows into the measurement window of the measuring instrument body causing contamination
Solution Approach 1:
The device is divided into distinct functional modules: the measurement strip with specimen inlet, the measurement unit with measurement window, and a detachable strip fixation unit. This segmentation allows the strip fixation unit to be removed for cleaning, preventing contamination accumulation in the measurement window while maintaining ease of specimen measurement operation.
Solution Approach 2:
The strip fixation unit is designed to be detachable from the measuring instrument body. This dynamic configuration allows the strip fixation unit to be easily removed for cleaning purposes, preventing contamination accumulation in the measurement window while maintaining ease of specimen measurement operation.
4Reliability
If the strip fixation unit is fixed permanently, then the measurement strip is securely held, but cleaning the measurement unit becomes difficult when specimen overflows
Solution Approach 1:
The strip fixation unit is designed to be detachable from the measuring instrument body. This dynamic configuration allows the strip fixation unit to be easily removed for cleaning purposes, preventing contamination accumulation in the measurement window while maintaining ease of specimen measurement operation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The integrated light-intensity check member prevents measurement errors, the detachable strip fixation unit simplifies cleaning, and the portable printer enhances convenience and accuracy in cholesterol measurement.
Implementation Method 1
a light-emitting unit which emits light to the measurement unit and detects the intensity of light reflecting after emitting the light to the measurement strip
Implementation Method 2
a light-intensity check member which reflects the light emitted from the light-emitting unit to check whether the intensity of light is abnormal
Data Source
AI summary
A cholesterol measurement device includes a measuring instrument body; and a light-intensity check member mounted on and integrated with the measuring instrument body. The light intensity check member reflects light emitted from a light-emitting unit, allowing detecting abnormal light intensity and accurate assessing light intensity change, which prevents a measurement value change due to the change in light intensity and improves reliability of the measurement value. The device keeps a measurement unit clean all the time since the measurement unit can be easily cleaned by separating a strip fixation unit, when a specimen flows into the strip fixation unit in which a measurement strip is inserted.
