Solution Overview

Problem

Existing vacuum cleaner charging stands lack a convenient storage solution for the power cord, leading to a messy and inefficient use of space.

Innovation Solution

A charging stand with a wire-winding frame that allows the power cord to be wound around it, combined with a pivotable pedal and safety protection devices, enabling organized storage and additional functionality such as hair cutting around the brushroll.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the charger is placed randomly after charging, then the charging stand is simple in structure, but the power cord becomes messy and storage becomes inconvenient

Engineering Contradiction:
Improvestorage convenienceVSAvoidstructure complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The wire-winding frame serves multiple functions: it winds and stores the power cord, provides a mounting structure for the charger, and defines the inserting slot position. This multi-functionality resolves the contradiction by improving storage convenience while avoiding additional separate components.

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

Solution Approach 2:

The patent combines the power cord storage function with the charger mounting structure into a single wire-winding frame component. By merging these functions, the patent improves organization and storage convenience without proportionally increasing structural complexity.

Inventive Principle:
Principle #5Merging (Combining)

2Ease of operation

If a wire-winding frame is added to organize the power cord, then storage convenience is improved, but the device complexity increases

Engineering Contradiction:
Improvestorage convenienceVSAvoidstructure complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The wire-winding frame is designed to perform multiple functions simultaneously: power cord winding, charger mounting, and inserting slot positioning. This multi-functionality ensures that storage convenience is improved while the increase in structural complexity is minimized by avoiding redundant components.

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

3Ease of operation

If the wire-winding frame is made movable between storage position and winding position, then ease of operation is improved, but device complexity and safety risks increase

Engineering Contradiction:
ImproveaccessibilityVSAvoidmechanism complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The wire-winding frame is designed with movable capability between storage position (within the body) and winding position (extending outward). This dynamic design improves accessibility and ease of operation while the complexity is managed through a relatively simple pivot or slide mechanism.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The movable design is applied locally only to the wire-winding frame portion that needs accessibility, while the rest of the charging stand maintains a simple fixed structure. This localized application of dynamics improves operation ease without proportionally increasing overall device complexity.

Inventive Principle:
Principle #3Local quality

4Reliability

If safety protection devices are added to control the pedal, then user safety is improved, but device complexity increases

Engineering Contradiction:
Improveuser safetyVSAvoidmechanism complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The safety protection devices are designed to prevent unintended pedal activation before it can occur. By having the safety mechanism engaged by default and requiring deliberate user action to disengage, the system prevents accidental operation while maintaining relatively simple mechanics.

Inventive Principle:
Principle #9Preliminary anti-action
