Solution Overview

Problem

Existing toilet bowl liners do not effectively address the need for reducing manual cleaning and odor elimination, as they lack pre-moistening with surfactants and humectants and the use of Essential Oils as a water surface barrier.

Innovation Solution

A pre-moistened, flexible, non-woven flushable liner shield permeated with surfactants, humectants, and Essential Oils, designed to form a barrier between the toilet bowl and solid waste, reducing odor by creating a surface barrier in the water.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a dry disposable toilet bowl liner shield is used, then the barrier function between the bowl and solid waste is provided, but manual cleaning is not sufficiently reduced and odor is not eliminated

Engineering Contradiction:
Improvemanual cleaning reductionVSAvoidtoilet odor
Core Design Contradiction:
Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The liner shield is pre-moistened with surfactant and humectant solutions before use, and pre-permeated with essential oils. This preliminary action ensures that the cleaning and odor-reducing functions are active from the moment the liner is placed in the bowl, maximizing effectiveness without requiring additional manual intervention.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The invention changes the physical and chemical parameters of the liner by impregnating it with liquid surfactant solutions and essential oils. This transforms the liner from a passive dry barrier to an active treatment medium that continuously reduces odor and facilitates cleaning through its moisture and chemical properties.

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If a dry disposable toilet bowl liner shield is used, then the barrier function is provided, but the cleaning effectiveness is insufficient

Engineering Contradiction:
Improvecleaning effectivenessVSAvoidmoisture content
Core Design Contradiction:
Ease of operationVSQuantity of substance

Solution Approach 1:

The liner's moisture content and chemical composition are changed by impregnating it with surfactant and humectant solutions. This parameter change transforms the liner into an effective cleaning agent that reduces surface tension and facilitates waste removal, thereby improving cleaning effectiveness.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The liner is constructed as a composite material combining the base liner substrate with impregnated surfactant and humectant solutions. This composite structure provides both the physical barrier function and the chemical cleaning properties, achieving enhanced cleaning effectiveness without excessive moisture.

Inventive Principle:
Principle #40Composite materials

3Object-generated harmful factors

If Essential Oils are used as a water surface barrier, then toilet odor is reduced or eliminated, but the complexity of the liner construction increases

Engineering Contradiction:
Improvetoilet odorVSAvoidliner construction complexity
Core Design Contradiction:
Object-generated harmful factorsVSDevice complexity

Solution Approach 1:

The invention merges multiple functions into a single liner product: the physical barrier function, the surfactant-based cleaning function, and the essential oil-based odor reduction function. By combining these elements into one integrated product, the complexity of implementation is reduced while maintaining all desired functions.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The liner is designed as a multi-functional product that simultaneously provides barrier protection, cleaning enhancement through surfactants, and odor reduction through essential oils. This universal design allows a single product to address multiple toilet hygiene issues without requiring separate devices or treatments.

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

AI summary

A pre-moistened (wet) with surfactant and humectant, flushable, toilet bowl liner shield which reduces the need for manual cleaning by providing a barrier shield between the bowl of the toilet and solid waste and using an Essential Oil based water surface barrier to reduce or eliminate toilet odor. The pre-moistened toilet bowl liner shield is for use in a flushable toilet wherein the water has an upper surface. The upper surface of the flat liner sits directly on top or slightly under the upper surface edge of the water. The liners reduce or prevent soiling of the interior of a toilet bowl and for efficient removal and flushing of human waste. The liners are treated with Essential Oils that create a surface barrier and reduce or eliminate toilet odor.
