Hand-held urinal with stabilizing mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hand-held urinals lack stability when urine is collected, making them difficult to hold due to changes in the center of gravity caused by added urine volume.
Innovation Solution
A hand-held urinal with a stabilizing mechanism, comprising a commercially available medical urinal, a weight bar, and a semi-rigid connector, which acts as a counterbalance to reduce the change in the center of gravity by dynamically adjusting the location of the weight bar and semi-rigid connector in response to urine addition, enhancing stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a standard medical urinal is used, then it is simple and commercially available, but it becomes unstable when urine is collected due to center of gravity shift
Solution Approach 1:
A weight bar is attached to the medical urinal to serve as a counterbalance. This counterweight compensates for the shift in center of gravity caused by urine collection, thereby maintaining the stability of the hand-held urinal during use.
Solution Approach 2:
The weight bar is connected to the medical urinal through a semi-rigid connector that allows dynamic adjustment. This enables the counterbalance mechanism to adapt to changing conditions during urine collection, optimizing stability throughout the process.
2Stability of the object's composition
If a weight bar and semi-rigid connector are added to counterbalance, then stability increases, but device complexity increases
Solution Approach 1:
The solution uses a straightforward counterbalance approach with a weight bar and semi-rigid connector, avoiding overly complex mechanisms while effectively addressing the stability issue through fundamental physics principles.
Solution Approach 2:
The semi-rigid connector provides the necessary dynamic adjustment capability with minimal complexity, allowing the weight bar to move and adapt to urine collection while maintaining a simple overall structure.
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 solution significantly increases the stability of the hand-held urinal, making it easier to hold during urine collection by minimizing the shift in the center of gravity caused by added urine, thereby improving user handling and comfort.
Implementation Method 1
The weight bar and the semi-rigid connector act as a counterbalance that adjusts the location of the first moment (often informally called the center of gravity) of the hand-held urinal with stabilizing mechanism
Implementation Method 2
The addition of the weight bar and the semi-rigid connector reduces the change in the first moment of the hand-held urinal with stabilizing mechanism that is caused by the addition of urine to the medical urinal

AI summary
The hand-held urinal with stabilizing mechanism is a hand-held collection device that comprises a medical urinal, weight bar, and a semi-rigid connector. The medical urinal is modified through the addition of the weight bar and the semi-rigid connector. The weight bar and the semi-rigid connector act as a counterbalance that adjusts the location of the first moment of the hand-held urinal with stabilizing mechanism relative to the first moment of just the medical urinal. The addition of the weight bar and the semi-rigid connector reduces the change in the first moment of the hand-held urinal with stabilizing mechanism that is caused by the addition of urine to the medical urinal during the use of the hand-held urinal with stabilizing mechanism. This makes the hand-held urinal with stabilizing mechanism easier to hold during the collection of urine.
