Blood Test Device Sensor Insertion Color Contrast
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional blood test apparatuses are difficult for diabetic retinopathy patients and old individuals with poor vision to operate due to similar color schemes between the sensor attaching part and the housing, making it hard to recognize the attaching part and operate the device effectively.
Innovation Solution
The blood test apparatus features a sensor attaching part and operation buttons with higher color values than the housing, utilizing colors identifiable by eyes with impaired blue cones, such as orange and red hues, to enhance visibility and contrast, along with possible fluorescent or phosphorescent coatings and light-emitting diodes for improved recognition in low-light environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the sensor attaching part has the same color as the housing, then the design is simple and aesthetically pleasing, but patients with vision problems cannot easily recognize the attaching part location
Solution Approach 1:
The patent applies color changes by making the sensor attaching part have a different color from the housing. Specifically, the attaching part is designed with a color that has a higher color value (more vibrant/saturated) than the housing color, making it visually distinct and easily recognizable for patients with vision problems while maintaining design simplicity.
Solution Approach 2:
The patent applies local quality by differentiating the color property of the attaching part from the housing. The attaching part specifically has a higher color value than the housing, creating a localized visual distinction that guides users to the correct insertion point without requiring complex overall design changes.
2Ease of manufacture
If operation buttons have the same color as the housing, then the device has a unified appearance, but users with impaired vision cannot easily identify the buttons
Solution Approach 1:
The patent applies color changes to the operation buttons by making them have a higher color value than the housing. This creates visual contrast that helps users with impaired vision easily locate and identify the buttons, while the buttons maintain aesthetic unity with the overall device design through coordinated color selection.
Solution Approach 2:
The patent applies local quality by giving the operation buttons a distinct color property (higher color value) compared to the housing. This localized differentiation enables users to easily identify button locations without compromising the overall aesthetic unity of the device.
3Ease of repair
If the blood sensor is detachably attached, then the sensor can be replaced and maintained, but users with vision problems have difficulty locating and inserting the sensor
Solution Approach 1:
The patent applies color changes to the sensor attaching part to create a visually distinct target area that guides users with vision problems during sensor insertion. The higher color value of the attaching part makes it easy to locate and align the sensor correctly, facilitating both replacement and proper insertion.
Solution Approach 2:
The patent applies local quality by differentiating the attaching part's color from the housing, creating a localized visual cue that guides sensor insertion. This localized distinction helps users easily identify where to insert the sensor while maintaining the detachable design for replacement and maintenance.
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
This design allows diabetic retinopathy patients and old individuals to easily identify and operate the attaching part and buttons, facilitating easier blood sugar level control and preventing or delaying the progression of complications like diabetic retinopathy.
Implementation Method 1
the surface color of the attaching part of the sensor has a higher color value than the surface color of the housing and has a color that can be identified by eyes with impaired blue cones

AI summary
It is intended to make it easy to recognize the attachment site of a blood sensor in a blood test device to which the blood sensor is attached by insertion. Especially, it is attempted to make the recognition of the attachment site easy and facilitate the insertion of a blood sensor which is to be attached to a blood test device by a person with visual impairment (in particular, a patient suffering from diabetic retinopathy) for the daily measurement of blood glucose level. More specifically speaking, it is intended to provide a blood test device comprising a housing; an electrical circuit unit contained in the housing; and an attachment site for inserting a blood sensor thereinto that is exposed on the surface of the housing; wherein the surface of the attachment site has a color which is lighter than the surface color of the housing and distinguishable by a patient having impairment in the blue cone.
