Solution Overview

Problem

Existing portable urine analysis devices lack a convenient and hygienic method for disposing of analyzed strips, leading to cumbersome disposal and potential hand contamination.

Innovation Solution

A portable urine analysis device with a modular, compact design featuring a tray that drops analyzed strips into an accommodation box for temporary storage, linked with an external electronic device for remote control and health information management, and a semi-automatic/automatic sheet system for hygiene and odor prevention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a portable urine analysis device is designed without a strip disposal mechanism, then the device structure remains simple and compact, but the user experiences cumbersome disposal and hand contamination

Engineering Contradiction:
Improvestrip disposal convenienceVSAvoiddevice structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The device automatically drops analyzed strips into the accommodation box using a movable tray mechanism, eliminating the need for manual disposal by the user. The system serves itself by automatically handling the waste strips after analysis is complete.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The device is divided into functional modules including a main body, a movable tray for holding strips, and a separate accommodation box for waste strips. This segmentation allows the disposal function to be added without redesigning the entire device structure.

Inventive Principle:
Principle #1Segmentation

2Object-affected harmful factors

If analyzed strips are stored in an open accommodation box, then the device maintains a compact structure, but hygiene is compromised and bad odor occurs

Engineering Contradiction:
Improvehygiene and odorVSAvoiddevice structure
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

A sheet is used to cover the accommodation box, creating a barrier that prevents odor escape and maintains hygiene. The sheet acts as a flexible barrier that can be easily implemented without adding rigid structural complexity.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The accommodation box is integrated within the main device body, and the sheet is nested within the accommodation box. This nested structure allows multiple functions (storage, coverage, hygiene protection) to be combined in a space-efficient manner.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Ease of operation

If a movable tray structure is used to drop strips, then power consumption increases, but strip disposal convenience is improved

Engineering Contradiction:
Improvestrip disposal convenienceVSAvoidpower consumption
Core Design Contradiction:
Ease of operationVSUse of energy by moving object

Solution Approach 1:

The movable tray operates periodically - moving to the dropped position only when needed to release analyzed strips, rather than continuously moving. This periodic operation reduces overall power consumption while maintaining disposal convenience.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The tray is designed to be movable rather than fixed, allowing it to dynamically change position between the loading position and the dropped position. This dynamic capability enables automatic strip disposal while consuming power only when position changes are required.

Inventive Principle:
Principle #15Dynamics
