Solution Overview

Problem

Existing potties often face difficulties in emptying waste in a controlled manner, leading to contamination of the seating surface, and they are not designed for efficient stacking, storage, or transportation.

Innovation Solution

A potty design featuring a passageway or duct that allows waste to be poured from the basin to a target site without contacting the seating surface, enabling controlled emptying and allowing for stackable configurations that save space during storage and transportation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If waste is emptied by tipping the potty, then the waste can be transferred to a toilet, but the waste may pass over the seating surface causing contamination

Engineering Contradiction:
Improvewaste emptyingVSAvoidseating surface contamination
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The duct is extracted from the basin and positioned to extend beyond the front of the potty, allowing waste to be discharged through a dedicated pathway that separates it from the seating surface. This extraction resolves the contradiction by providing a controlled emptying route that prevents contamination.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The duct acts as an intermediary element between the basin and the external environment. It mediates the waste transfer process by providing a controlled passage that directs waste away from the seating surface, thus preventing contamination while enabling easy emptying.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If a duct is added to provide controlled pouring, then hygiene is improved, but the device complexity increases

Engineering Contradiction:
Improvewaste contaminationVSAvoidpotty structure
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The potty is segmented into functional zones: the basin for waste collection, the duct for controlled discharge, and the seating surface for user comfort. This segmentation allows each component to perform its specific function efficiently while maintaining overall simplicity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The duct is merged with the potty body as an integrated feature rather than a separate attachment. This combining approach maintains hygiene benefits while minimizing additional complexity by making the duct an inherent part of the potty structure.

Inventive Principle:
Principle #5Merging (Combining)

3Productivity

If the potty is designed for stacking, then storage and transportation efficiency is improved, but the design flexibility is reduced

Engineering Contradiction:
Improvestorage efficiencyVSAvoiddesign configuration
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The duct extends beyond the front of the potty in a horizontal direction, creating a dimensional feature that enables stacking. When multiple potties are stacked, the ducts align to form a continuous pathway, allowing waste to be poured through multiple potties simultaneously. This dimensional extension resolves the contradiction by providing both stacking capability and design flexibility.

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

Solution Approach 2:

The duct serves multiple functions: it provides controlled waste discharge, enables stacking by aligning with other potties, and maintains hygiene by preventing contamination. This multi-functionality resolves the contradiction by making the same structural element serve both stacking and hygiene purposes.

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

AI summary

A potty (10) includes a sidewall (12), basin (14) and a top surface (15) including a seating surface (18). The potty (10) is arranged such that it can be stacked with a similar potty such that a part of one is received within the other. This results in the combined height of the stacked potties being less than twice the height of an individual potty. The potty (10) has a duct (20) that enables liquid to be poured from the basin (14) out of the potty substantially without coming into contact with the seating surface (18).
