Motorized IV Pole Height Control Using Fluid Weight Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional IV stands are not height adjustable, lack weight or fluid level sensors, and require manual adjustment, leading to user fatigue and inconsistent fluid infusion rates.
Innovation Solution
A self-adjusting IV stand with motor-driven poles and integrated weight measurement devices that electronically control the pole height based on fluid weight, providing real-time feedback for precise flow rate control and automatic height adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual adjustment mechanisms are used, then ease of operation is improved, but device complexity increases and productivity decreases
Solution Approach 1:
The patent replaces manual mechanical adjustment mechanisms with an automated motorized system. The motorized pole assembly includes a drive mechanism that automatically extends and retracts the pole to adjust height, eliminating the need for manual operation while reducing overall device complexity through integration of control systems.
Solution Approach 2:
The system incorporates weight measurement assemblies that automatically detect fluid container weight and trigger height adjustments without user intervention. The pole assembly self-adjusts its position based on detected weight changes, enabling the system to serve itself rather than requiring manual operation.
2Productivity
If motorized pole assembly is added, then productivity is improved, but device complexity increases
Solution Approach 1:
The patent combines the motorized pole assembly with the weight measurement assembly into an integrated system. The drive mechanism of the pole assembly is controlled by signals from the weight measurement assembly, merging detection and actuation functions into a unified device that improves productivity without proportionally increasing complexity.
Solution Approach 2:
The motorized pole assembly serves multiple functions: it adjusts height based on weight detection, maintains consistent infusion rates through automated positioning, and can respond to various fluid container weights. This multi-functionality improves productivity while justifying the added complexity through versatile operation.
3Measurement precision
If weight measurement assembly is integrated, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The weight measurement assembly provides real-time feedback on fluid container weight to the pole assembly control system. This feedback loop enables precise measurement and automatic adjustment of pole height based on detected weight changes, improving measurement precision while using the feedback mechanism to simplify overall system operation.

AI summary
IV stand assemblies are provided that include a base, a stand, a platform and a motorized pole assembly having a housing, a pole and a drive. The drive moves the pole to extend and retract the pole relative to the housing. A weight measurement assembly measures weight of a fluid within a fluid container hanging from the IV stand assembly. IV stand assemblies with a pulley/belt assembly and methods of operating IV assemblies are also provided.
