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 charger can be easily set aside, but the power cord becomes messy and storage becomes inconvenient

Engineering Contradiction:

Improveease of setting aside chargerVSAvoidorderliness of power cord

Core Design Contradiction:

Ease of operationVSStability of the object's composition

Solution Approach 1:

The power cord winding function is extracted from the main body structure and implemented through a separate wire-winding frame with a rotating reel. This allows the power cord to be independently wound and stored, separating the cord management function from the charger placement function, thus maintaining orderliness while preserving ease of operation.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The wire-winding frame is designed to be rotatable around the charging stand, transforming a static structure into a dynamic one. This rotational movement enables the power cord to be neatly wound during storage and easily deployed during use, dynamically adapting to different operational states while maintaining both convenience and orderliness.

Inventive Principle:

Principle #15Dynamics

2Productivity

If the power cord is not wound up, then the charger can be quickly placed, but space is wasted and storage efficiency decreases

Engineering Contradiction:

Improvecharging speedVSAvoidspace occupied by charging stand

Core Design Contradiction:

ProductivityVSVolume of stationary object

Solution Approach 1:

The wire-winding frame with the coiled power cord is designed to nest within or alongside the charging stand structure. When the power cord is fully wound, it occupies minimal space integrated into the overall charging station footprint, effectively nesting the cord storage function within the existing volume without requiring additional external space.

Inventive Principle:

Principle #7Nested doll (Nesting)

3Stability of the object's composition

If a wire-winding frame is added to the charging stand, then the power cord can be organized and space reduced, but the device complexity increases

Engineering Contradiction:

Improveorganization of power cordVSAvoidstructure of charging stand

Core Design Contradiction:

Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The charging stand system is segmented into distinct functional modules: the main charging body, the wire-winding frame with rotating reel, and the integrated power cord. This segmentation allows each component to perform its specific function independently, simplifying the overall design logic and making the complex organization of the power cord manageable through modular construction.

Inventive Principle:

Principle #1Segmentation
