Urine Analysis Fastening Arm for Irregular Toilet Bowl Geometry
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing urine analysis devices face challenges in securing to different toilet bowl shapes, particularly those with shoulders or projections, leading to improper installation and potential interference, which affects the stability and accuracy of urine collection.
Innovation Solution
A urine analysis device with a fastening arm that includes a proximal attachment portion forming a receiving space from the rear face to beyond the edge, allowing the device to conform to various toilet bowl shapes, ensuring stable and secure positioning by avoiding contact with irregular geometries.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a hook arm is used to secure the urine analysis device to the toilet bowl, then the device can be attached to the toilet, but the arm may contact irregular geometries (shoulders, projections) on different toilet bowl shapes, causing improper installation and instability
Solution Approach 1:
The fastening arm is designed as a flexible component that can bend and adapt to different toilet bowl geometries. The arm includes a receiving space that allows it to conform to various shapes without contacting irregular features like shoulders or projections, ensuring stable attachment across different toilet designs while maintaining mechanical stability under lateral forces
Solution Approach 2:
The fastening arm transitions from a rigid structure to a dynamic, adaptable component. The flexible design allows the arm to change its configuration based on the toilet bowl shape, enabling reliable attachment while avoiding interference from geometric irregularities through controlled deformation
2Device complexity
If the fastening arm extends straight from the attachment element, then the structure is simple, but it may contact irregular geometries on the toilet bowl and force the device into incorrect positioning
Solution Approach 1:
The fastening arm employs a flexible design with a receiving space that allows it to bend away from irregular geometries on the toilet bowl. This prevents the arm from forcing the device into incorrect positioning while maintaining a relatively simple overall structure that is easy to manufacture
3Device complexity
If the receiving space extends only to the rear face edge, then the fastening arm structure is simpler, but it cannot provide sufficient mechanical stability under lateral forces or flushing turbulence
Solution Approach 1:
The receiving space extends beyond the rear face edge to provide increased structural support and mechanical stability. This extended geometry allows the flexible arm to better resist lateral forces and flushing turbulence while maintaining adaptability to different toilet bowl shapes
