Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional pop-up style dispensers for sheet materials like facial tissues expose tissues before use, risking contamination, malfunction during dispensing, and require a removable flap that is not recycled.

Innovation Solution

A dispenser with a housing and a conveyor system where pulling a tab member laterally moves a tray member outside the housing to dispense sheet materials, maintaining them enclosed until needed, and pushing the tab member back retracts the tray member for protection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If pop-up style dispensers are used to expose tissues for individual use, then ease of operation is improved, but the tissues become vulnerable to contamination and malfunction

Engineering Contradiction:

Improveease of dispensingVSAvoidcontamination risk

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The tray member is nested within the housing, allowing the sheet material to be protected inside the housing while still enabling access through the tray member's movement. The tray member acts as a nested component that can be pulled out to dispense material while maintaining protection when retracted.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The sheet material is pre-positioned on the tray member inside the housing in a protected state. The system prepares the material in advance but keeps it enclosed until dispensing is needed, eliminating the need for a removable flap while maintaining protection.

Inventive Principle:

Principle #10Preliminary action

2Ease of operation

If a removable perforated flap is used to access the dispensing window, then ease of operation is improved, but the flap cannot be recycled with the dispenser

Engineering Contradiction:

Improveease of accessVSAvoidrecyclability

Core Design Contradiction:

Ease of operationVSLoss of substance

Solution Approach 1:

The tray member and housing are designed as integrated components that can be recycled together. The tray member remains attached to the housing structure, eliminating the need for separate removal and recycling of flaps. This merged structure maintains ease of access while improving recyclability.

Inventive Principle:

Principle #5Merging (Combining)

3Object-affected harmful factors

If the tray member is kept inside the housing for protection, then contamination is prevented, but the sheet material cannot be dispensed

Engineering Contradiction:

Improvecontamination preventionVSAvoidease of dispensing

Core Design Contradiction:

Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The tray member is designed to be dynamically movable between a retracted position inside the housing for protection and a extended position for dispensing. This dynamic movement allows the system to switch between protected storage and accessible dispensing states as needed.

Inventive Principle:

Principle #15Dynamics

AI summary

A dispenser for sheet materials is disclosed that has a unique opening feature. The dispenser includes a housing that encloses a tray for containing one or more sheet materials. The dispenser further includes a tab member that is attached to an internal conveyor system. When the conveyor system is pulled out, the tray member exits the housing for enabling a user to have access to the sheet materials for dispensing.
