Vital Parameter Sensor Damped Mounting for Accurate Readings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing measurement devices for vital parameters often provide unreliable and falsified readings due to interaction with the body, such as pressure exertion, which affects the measurement values and is particularly problematic for long-term or permanent wear.
Innovation Solution
A measurement device with a sensor mounted in a damped manner within a recess of the base body, allowing for a movable and elastic connection that minimizes external forces' influence on the sensor, ensuring it operates within the normal venous pressure range to avoid interfering with blood flow and maintain accurate readings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the sensor is rigidly connected to the base body, then the sensor remains stable in position, but external forces are transferred to the sensor causing measurement falsification
Solution Approach 1:
The patent introduces a means for pressure regulation as an intermediary element between the base body and the sensor. This mediator absorbs and regulates external forces, preventing them from being transferred to the sensor while maintaining the sensor's positional stability. The pressure regulation means acts as a buffer that decouples the sensor from direct force transmission pathways.
Solution Approach 2:
The patent extracts the force transmission function from the sensor mounting structure by separating the sensor's positional support function from the force transmission path. The means for pressure regulation is specifically designed to handle external forces, allowing the sensor to remain isolated from these harmful influences while maintaining its measurement function.
2Reliability
If the sensor is mounted with high contact pressure, then measurement contact is ensured, but blood flow is hindered and measurements become unreliable
Solution Approach 1:
The patent dynamically adjusts the contact pressure parameter of the sensor to maintain it within an optimal range. The means for pressure regulation modifies the pressure parameter in real-time, ensuring sufficient contact for reliable measurements while preventing excessive pressure that would hinder blood flow. This parameter optimization resolves the contradiction between measurement reliability and physiological compatibility.
3Stability of the object's composition
If the measurement device is worn tightly, then device stability is improved, but the sensor pressure on skin increases causing measurement falsification
Solution Approach 1:
The means for pressure regulation serves as an intermediary that decouples the fastening force from the sensor pressure. When the device is worn tightly, the fastening force is absorbed by the pressure regulation means rather than being directly transmitted to the sensor. This mediator protects the sensor from excessive pressure while allowing the device to maintain stable wear.
