Solution Overview

Problem

Existing urine analysis devices face challenges in securely attaching to toilet bowls of varying shapes, leading to improper installation and potential contact with the bowl wall, which can disrupt the device's positioning and functionality.

Innovation Solution

A urine analysis kit with a housing and a mounting arm featuring a proximal attachment portion that forms a receiving space for the housing, allowing the device to conform to different toilet bowl shapes, ensuring a stable and secure fit by extending beyond the edge of the rear face and incorporating a flexible, removable fixing arm with a distal attachment portion for secure attachment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a straight hook arm is used to attach the urine analysis device to the toilet bowl, then the device can be securely attached, but the arm may contact the bowl wall and force the device into an unsuitable position, especially with toilets having a shoulder close to the rim

Engineering Contradiction:
Improveattachment securityVSAvoidproper positioning
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The mounting arm incorporates a curved geometry with a receiving space that conforms to the housing shape, allowing the arm to wrap around the housing and engage with the rim without contacting the bowl wall. This curved design enables proper positioning while maintaining secure attachment.

Inventive Principle:
Principle #14Spheroidality (Curvature)

2Adaptability or versatility

If the mounting arm is designed to fit various toilet bowl shapes, then compatibility is improved, but the design complexity increases

Engineering Contradiction:
Improvecompatibility with different toilet shapesVSAvoidmounting arm design
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The mounting arm is designed as a universal component with a curved receiving space that can accommodate multiple housing shapes and toilet bowl configurations. The curved geometry provides adaptability across different toilet types without requiring multiple specialized arm designs.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The mounting arm utilizes material flexibility and geometric curvature parameters to adapt to varying toilet bowl shapes. The curved receiving space can deform within elastic limits to conform to different housing configurations, providing versatility without complex mechanical adjustments.

Inventive Principle:
Principle #35Parameter changes

3Ease of operation

If the receiving space extends beyond the edge of the rear face, then the mounting arm can properly position the device and prevent wall contact, but the overall device size increases

Engineering Contradiction:
Improveproper positioningVSAvoiddevice size
Core Design Contradiction:
Ease of operationVSVolume of moving object

Solution Approach 1:

The receiving space extends in a curved path beyond the rear face edge, utilizing three-dimensional spatial arrangement to achieve proper positioning. This dimensional extension allows the mounting arm to clear the bowl wall while maintaining a compact overall device footprint through efficient spatial configuration.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
