Solution Overview

Problem

Traditional toilet training methods delay children's potty training and cause anxiety by requiring them to sit on a flush toilet in an adult style, reducing sensory and cognitive perception of the toilet, leading to aversion and increased diaper use.

Innovation Solution

The Reverse Toilet Training (RTT) device positions children to face the rear of the toilet, allowing them to view the flushing mechanism and lid, with interactive elements like toys, footrests, and rewards to enhance engagement and familiarity with the flush toilet, while providing safety features to prevent accidents.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If children are trained to sit on the toilet in adult style (facing away from the cistern), then they can use the toilet like adults, but their sensory and cognitive perception of the flush toilet is reduced, leading to aversion and delayed training

Engineering Contradiction:
Improvetoilet usage convenienceVSAvoidsensory and cognitive perception of the flush toilet
Core Design Contradiction:
Ease of operationVSLoss of information

Solution Approach 1:

The patent inverts the traditional toilet training orientation by positioning the child to face the rear of the toilet (toward the cistern and flushing mechanism) instead of facing away as in adult-style training. This inversion allows the child to visually observe and cognitively engage with the flushing mechanism, transforming the toilet from an abstract object into a visible, understandable system that reduces aversion and enhances perception.

Inventive Principle:
Principle #13The other way round (Inversion)

2Reliability

If traditional adult-style toilet training is used, then the child can eventually use the toilet, but the training process is delayed and causes greater anxiety in parent and child

Engineering Contradiction:
Improvetoilet training successVSAvoidtoilet training duration
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by introducing an interactive device with visual and tactile elements before the child begins formal toilet training. The device pre-acclimates the child to the toilet environment and flushing mechanism through engaging interactions, building familiarity and reducing anxiety before the actual training process begins, thereby accelerating overall training success.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The interactive device provides immediate visual feedback (flushing animation, moving parts) and tactile feedback (buttons, levers) that respond to the child's actions. This feedback loop helps the child understand cause-and-effect relationships in the flushing process, reinforcing positive behavior and reducing training time through engaging, responsive interactions.

Inventive Principle:
Principle #23Feedback

3Ease of operation

If the child sits facing away from the toilet lid and flushing mechanism, then they can use the toilet in adult style, but the toilet lid may fall on the child and there is no support for the child to hold on to

Engineering Contradiction:
Improvetoilet usage simplicityVSAvoidtoilet lid falling on child and lack of support
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The interactive device serves as an intermediary element positioned between the child and the flushing mechanism. It provides a safe, child-appropriate interface with large buttons and levers that the child can operate without risk. The device mediates the interaction by translating simple child actions into the flushing function, eliminating the need for the child to reach for or manipulate the actual flush handle or lid, thereby preventing injury while maintaining functionality.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Adaptability or versatility

If children are required to sit adult-style on the toilet, then they can use the toilet like adults, but they establish early aversion towards using the toilet and may refuse to use it later

Engineering Contradiction:
Improvetoilet usage adaptabilityVSAvoidchild aversion and refusal to use toilet
Core Design Contradiction:
Adaptability or versatilityVSObject-generated harmful factors

Solution Approach 1:

The patent inverts the traditional approach by having the child face the rear of the toilet toward the cistern and flushing mechanism rather than facing away. This inversion transforms the toilet from a mysterious, intimidating object into a visible, understandable system. The child can observe the flushing process, understand how it works, and feel a sense of control and curiosity satisfaction, which eliminates aversion and promotes long-term willingness to use the toilet.

Inventive Principle:
Principle #13The other way round (Inversion)

Solution Approach 2:

The patent replaces the abstract, invisible flushing mechanism with a visible, interactive mechanical display that shows the flushing process in an engaging way. The interactive device incorporates moving parts, animations, or visual indicators that make the invisible flush process visible and understandable to the child, transforming a potentially frightening mechanical event into an educational and reassuring experience.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

AI summary

An interactive device that is an accessory to a flush toilet and is positioned at the rear of the flush toilet and may be attached to the rear of the toilet such that the user would use the flush toilet in the reverse position. The interactive device may include a toy, game, or computer. The interactive device may be secured to the toilet by straps or to the toilet lid hinges and may be detachable from the flush toilet. The interactive device may have hinges that allow the interactive device to be folded to a compact configuration. The interactive device makes “going to the bathroom” enjoyable for both the child and parent, while educating the child to appreciate and to become more accustomed to using a flush toilet.
