Weight Scale with Color-Coded Visual Feedback for Heart Failure Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Patients with congestive heart failure face challenges in self-monitoring and self-administering therapies effectively, leading to potential complications due to lack of clear indicators for maintaining homeostasis, particularly in determining when to initiate self-administration of medications or seek medical treatment.
Innovation Solution
An electronic weight scale with a large, flat, and accessible design that provides visual cues through color-coded light indications (green, yellow, and red) to inform patients whether they are maintaining homeostasis, require self-management, or need medical intervention, along with a removable memory device for data collection and sharing with healthcare providers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a patient self-monitors and self-administers therapies for congestive heart failure without medical training, then the patient can manage their condition at home, but the patient cannot accurately determine whether they are properly implementing therapies leading to potential complications
Solution Approach 1:
The weight scale provides immediate visual feedback through color-coded lights (green, yellow, red) that indicate whether the patient's weight is within the target range, requires self-management, or requires medical intervention. This feedback loop enables the patient to understand the effectiveness of their self-administered therapies without needing medical training.
Solution Approach 2:
The weight scale acts as an intermediary device between the patient and healthcare providers, translating complex medical monitoring requirements into simple visual cues that the patient can interpret and act upon independently.
2Measurement precision
If the weight scale provides detailed medical monitoring capabilities, then the patient can accurately track their condition, but the device complexity increases making it harder for laypeople to use
Solution Approach 1:
The scale uses color-coded visual indicators (green light for target range, yellow light for self-management needed, red light for medical intervention needed) to communicate complex weight status information in a simple, intuitive manner that requires no medical knowledge to interpret.
Solution Approach 2:
The scale is designed to be fully operational by the patient themselves, with automatic weight measurement, automatic comparison to target ranges, and automatic generation of visual feedback, eliminating the need for manual calculation or interpretation by the patient.
3Productivity
If the patient delays seeking medical treatment until symptoms worsen, then the patient can manage minor fluctuations independently, but significant complications can occur including death
Solution Approach 1:
The scale identifies weight trends that indicate impending decompensation before serious symptoms develop, allowing the patient to take preliminary actions (such as contacting their healthcare provider) before the condition deteriorates to a critical state.
Solution Approach 2:
The continuous visual feedback from the color-coded lights enables the patient to detect problematic weight trends early and adjust their self-management approach or seek medical intervention at the appropriate time, improving both the timeliness and reliability of interventions.
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 electronic weight scale effectively guides patients in managing congestive heart failure by providing clear visual cues for appropriate interventions, ensuring timely self-administration of therapies or medical treatment, thereby preventing complications and improving homeostasis management.
Implementation Method 1
a weight measurement device (202) operable with the substantially flat planar surface (102)
Implementation Method 2
a plurality of light sources (107, 108, 109) disposed along the substantially flat planar surface (102) and operable with the control circuit (201) to selectively present one of three color-coded indications
Data Source
AI summary
A weight scale (100) for assisting with management of congestive heart failure and other ailments includes a housing (101) that can define a substantially flat planar surface (102). A weight measurement device (202) measures a weight of a user. A control circuit (201) stores in a memory (203) a first predefined weight threshold (205) and a second predefined weight threshold (206). The scale includes light sources (107,108,109) operable with the control circuit to selectively present one of three color-coded indications. When the weight is between the below the first predefined weight threshold, the light sources present a first color indication. When the weight is between the first predefined weight threshold and the second predefined weight threshold, the light sources present a second color indication. When the weight is above the second predefined weight threshold, the light sources present a third color indication.
