Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing methods for winding and storing extension cords and hoses are labor-intensive, time-consuming, and prone to tangling, leading to physical exhaustion and potential accidents due to improper storage.

Innovation Solution

A cord spooler device with a cylindrical body that rotates 360 degrees around an axle, allowing manual or powered winding via a hand crank or motor, and featuring a recessed area with a fastener to secure the cord or hose during winding, preventing tangling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual winding by hand is used, then no additional device is needed, but the process is labor-intensive and time-consuming

Engineering Contradiction:
Improveease of windingVSAvoidwinding time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The patent replaces the manual mechanical winding system with an automated motor-driven spooler system. The motor automatically winds the cord or hose onto the spool, eliminating the need for manual hand-winding operations and significantly reducing both labor intensity and time required.

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

Solution Approach 2:

The spooler device is designed to perform the winding operation autonomously once activated. The motor-driven mechanism automatically winds the cord or hose without requiring continuous manual intervention, allowing the system to service itself through automated operation.

Inventive Principle:
Principle #25Self-service

2Ease of operation

If manual winding by hand is used, then no additional device is needed, but physical strain and fatigue occur

Engineering Contradiction:
Improveease of windingVSAvoidphysical strain
Core Design Contradiction:
Ease of operationVSForce

Solution Approach 1:

The patent replaces the manual mechanical winding system with an automated motor-driven spooler system. The motor automatically winds the cord or hose onto the spool, eliminating the need for manual hand-winding operations and significantly reducing labor intensity and time required.

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

3Device complexity

If cord or hose is not secured during winding, then the device structure is simpler, but tangling occurs

Engineering Contradiction:
Improvedevice structureVSAvoidtangling prevention
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The patent incorporates a clamping mechanism that secures the cord or hose to the spool before the winding process begins. This preliminary action of clamping prevents the cord or hose from becoming tangled during rotation, ensuring reliable operation without requiring complex additional structures.

Inventive Principle:
Principle #10Preliminary action

4Area of stationary object

If proper storage is not implemented, then storage space requirements are reduced, but damage and safety hazards increase

Engineering Contradiction:
Improvestorage spaceVSAvoiddamage and tripping hazards
Core Design Contradiction:
Area of stationary objectVSObject-affected harmful factors

Solution Approach 1:

The patent designs a compact storage system where the wound cord or hose is neatly organized on the spool, which can then be stored in a vertical rack or mounted in a confined space. This nesting approach allows proper storage in minimal space while preventing damage and safety hazards through organized containment.

Inventive Principle:
Principle #7Nested doll (Nesting)

AI summary

A cord spooler device is provided comprised of a cylindrical body that facilitates the organized winding of a power cord or hose. The body, which can rotate 360 degrees around a vertical axis on an axle attached to a base, may include a tapered design for enhanced cord management. The device allows for manual rotation through a hand crank or powered rotation via a motor or can be adapted for use with a drill or electric rotary tool. The body features a recessed area with a fastener to secure a first end of a cord or hose prior to/during winding. During winding, the power cord or hose is neatly wound around the body, wherein the cord or hose can then be removed from the body in a wound state.
