Child Training Toilet Seat Linkage for Waste Receptacle Closure

Solution Overview

Problem

Conventional child training toilets allow unrestricted access to the waste receptacle, posing hygiene issues and requiring additional cleaning due to children's tendency to visually and physically engage with the waste.

Innovation Solution

A child training toilet with a base and waste receptacle featuring a centrally located opening, a movably mounted seat, and a hingedly mounted access door with engagement rods to transition between open and closed positions, inhibiting access to the waste receptacle.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the waste receptacle is left open for easy access during use, then the ease of operation is improved, but hygiene safety deteriorates as children can visually and physically engage with the waste

Engineering Contradiction:
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The access door is automatically closed by the seat's upward movement after use, preventing children from accessing waste before they can even see it. This preliminary action of closing the door eliminates the hygiene hazard while maintaining ease of operation during actual use.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The access door transitions from a static barrier to a dynamic component that automatically opens when the seat is pressed down and closes when the seat returns to its upright position. This dynamic behavior allows easy access during use while preventing access afterward.

Inventive Principle:
Principle #15Dynamics

2Object-affected harmful factors

If an access door is added to prevent waste access, then hygiene safety is improved, but device complexity increases due to additional moving parts

Engineering Contradiction:
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The access door mechanism is merged with the existing seat assembly. The seat's downward movement directly opens the door, and the seat's upward movement automatically closes it. This integration eliminates the need for separate motors, sensors, or control systems, adding minimal complexity while achieving the hygiene safety goal.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The access door operates autonomously through the mechanical action of the seat itself. When a child sits on the seat, the door automatically opens; when the child stands up, the door automatically closes. This self-service mechanism requires no additional power source or control system, minimizing the increase in device complexity.

Inventive Principle:
Principle #25Self-service

3Ease of operation

If the seat is made movable to operate the access door, then ease of operation is improved for waste deposition, but reliability may worsen due to additional moving parts that could fail

Engineering Contradiction:
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The seat's weight and position naturally drive the door operation. Sitting down opens the door; standing up closes it. This self-service mechanism eliminates the need for motors, batteries, or electronic controls, significantly improving reliability while maintaining ease of operation for waste deposition.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The toilet is segmented into functionally independent components: the seat assembly, the access door, and the waste receptacle. Each component operates independently through simple mechanical linkages, reducing the risk of system-wide failure and improving overall reliability while facilitating easy waste deposition.

Inventive Principle:
Principle #1Segmentation

AI summary

A child training potty configured to inhibit access to a waste receptacle thereof so as to prevent contact with human waste present therein. The child training potty includes a base being formed from a plurality of walls and a bottom creating an interior volume. A waste receptacle is disposed within the interior volume of the base and is releasably secured therein. A seat member is superposed the base and is movably mounted thereto wherein the seat member is configured to traverse in an upwards-downwards direction. A plurality of springs are intermediate the seat member and the base. An access door is hingedly secured proximate the opening of the waste receptacle. The seat member further has engagement rods extending downward therefrom that are operable to move the access door from a first position to a second position. The access door includes a first portion and a second portion.
