Solution Overview

Problem

Existing roll dispenser devices are not designed to fit within kitchen drawers or cabinets and lack a hinged lid with a finger access hole for easy access and replacement of the dispensed items.

Innovation Solution

A rectangular prismatic housing with a hinged lid and dowel rod system that fits within a kitchen drawer or can be hung on a cabinet, featuring a cutter integrated into the lid for convenient cutting and storage of rolled goods like aluminum foil and stretch wrap.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If existing roll dispenser devices are used, then they can dispense rolled goods, but they cannot fit within kitchen drawers or cabinets

Engineering Contradiction:

Improvehousing sizeVSAvoidfit within kitchen drawer

Core Design Contradiction:

Volume of moving objectVSAdaptability or versatility

Solution Approach 1:

The housing dimensions are specifically designed and adjusted to fit standard kitchen drawer spaces, transforming the device from a generic size to a compact configuration that adapts to the constrained kitchen environment while maintaining all dispensing functions

Inventive Principle:

Principle #35Parameter changes

2Ease of operation

If existing roll dispenser devices are used, then they can store rolled goods, but they lack a hinged lid with finger access hole for easy replacement

Engineering Contradiction:

Improveaccess to replace itemVSAvoidhousing structure

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The lid is separated from the main housing body and connected via hinges, allowing independent movement of the lid portion. This segmentation enables the lid to be opened for item replacement while the housing remains stationary, improving accessibility without requiring complete disassembly

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A finger access hole is introduced as an intermediary element in the lid, allowing users to insert their finger to easily lift and open the lid. This small opening acts as a mediator that enables simple one-handed operation without requiring grasping of the entire lid

Inventive Principle:

Principle #24Intermediary (Mediator)

3Ease of operation

If existing roll dispenser devices are used, then they can hold rolled goods, but they lack integrated cutting functionality

Engineering Contradiction:

Improvecutting convenienceVSAvoiddevice structure

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The cutter is integrated directly into the lid structure, merging the cutting function with the opening mechanism. When the lid is opened for item replacement, the cutter becomes accessible for cutting the rolled good, combining two functions (lid operation and cutting) into a single integrated component rather than separate elements

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A roll dispenser drawer insert apparatus for convenient storage and dispensing of rolled goods includes a housing that fits within a kitchen drawer. A pair of dowel supports is coupled to a housing left side and a housing right side within a housing inside. A dowel rod is coupled to the pair of dowel supports and secures a rolled good such as, but not limited to, aluminum foil, stretch wrap, wax paper, paper towels, and the like. A lid is hingingly coupled to the housing top side adjacent a housing back side and moves between a closed position covering an open portion of the housing top side and an open position exposing the open portion of the housing top side. A cutter is coupled to a lid underside of the lid adjacent a lid front side of the lid.
