Blood Pressure Device Flow Path Plate for Compact Component Testing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing blood pressure measurement devices face challenges in testing components without increasing the size of the flow path plate unit due to mechanisms that block unnecessary flow paths.
Innovation Solution
A blood pressure measurement device with a flow path plate unit that allows independent connection of components and cuffs or testers, enabling individual testing without enlarging the unit by using internal flow paths that can be connected selectively to cuffs or testers, and allowing sealing when testing is not performed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a mechanism that blocks unnecessary flow paths is provided in the flow path plate unit, then components can be tested individually, but the flow path plate unit increases in size
Solution Approach 1:
The flow path plate unit is divided into multiple independent internal flow paths (first internal flow path, second internal flow path, third internal flow path) that can be selectively activated. Each flow path can be independently controlled to connect components to either cuffs or testers, allowing individual component testing without requiring all flow paths to be simultaneously accessible. This segmentation enables compact design while maintaining testing versatility.
Solution Approach 2:
The flow path plate unit incorporates dynamic flow path selection through selective connection mechanisms. The internal flow paths can be dynamically configured to connect components to different destinations (cuffs or testers) based on operational mode. This dynamic capability allows the same compact structure to serve multiple functions: normal operation with cuffs and testing mode with testers, without requiring physical enlargement.
2Adaptability or versatility
If multiple flow paths are made independent for testing, then individual component testing is enabled, but the device complexity increases
Solution Approach 1:
Multiple flow paths are merged into a single integrated flow path plate unit structure. The first, second, and third internal flow paths share common components (pump, valve, pressure sensor) and converge at shared connection points. This merging approach allows independent flow path control for testing while avoiding the complexity of completely separate testing systems. The unified structure reduces overall device complexity compared to having discrete independent flow path assemblies.
Solution Approach 2:
The internal flow paths serve multiple functions: during normal operation, they connect components to cuffs for blood pressure measurement; during testing, they connect components to testers for component validation. This multi-functionality reduces device complexity by eliminating the need for separate dedicated testing flow paths. The same physical infrastructure supports both operational and testing modes, simplifying the overall device architecture.
