Solution Overview

Problem

Conventional waste receptacles often require separate storage for spare toilet tissue rolls, leading to clutter and inconvenience in bathrooms.

Innovation Solution

A molded plastic waste receptacle with an integrated storage compartment below the main receptacle volume, designed to accommodate one or more conventionally sized rolls of toilet tissue, eliminating the need for external stacking.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If separate storage for spare toilet tissue rolls is used, then waste receptacle function is provided, but bathroom clutter increases and space efficiency decreases

Engineering Contradiction:
Improveconvenience of waste receptacle usageVSAvoidbathroom space occupied
Core Design Contradiction:
Ease of operationVSArea of stationary object

Solution Approach 1:

The patent combines the waste receptacle and tissue roll storage into a single integrated unit. The storage compartment is positioned directly above the waste receptacle, allowing both functions to occupy the same footprint space. This merging eliminates the need for separate storage locations for tissue rolls, thereby reducing bathroom clutter while maintaining ease of access to both waste disposal and tissue rolls.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The integrated device serves multiple functions within a single structure: it provides waste receptacle functionality below and tissue roll storage above. This multi-functional design allows the same space to serve dual purposes, improving space efficiency without compromising the ease of operation for either function.

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

2Reliability

If multiple separate devices are used for waste and tissue storage, then individual functions are optimized, but device complexity and cleaning difficulty increase

Engineering Contradiction:
Improvefunctionality of waste receptacleVSAvoidnumber of separate components
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

By merging the waste receptacle and tissue storage into a single integrated unit, the patent reduces the number of separate components from two to one. This simplification maintains the reliability of waste receptacle functionality while reducing device complexity and the associated cleaning burden of multiple separate devices.

Inventive Principle:
Principle #5Merging (Combining)

3Ease of operation

If tissue rolls are stacked near the toilet, then accessibility is improved, but aesthetic appearance and organization deteriorate

Engineering Contradiction:
Improveaccessibility of tissue rollsVSAvoidbathroom organization and aesthetics
Core Design Contradiction:
Ease of operationVSShape

Solution Approach 1:

The integration of tissue roll storage into the waste receptacle structure creates a unified, organized appearance rather than scattered rolls near the toilet. The designated storage compartment maintains aesthetic appeal while keeping tissue rolls easily accessible, thus improving both appearance and organization without sacrificing accessibility.

Inventive Principle:
Principle #5Merging (Combining)
