Vacuum Charging Stand Cord-Winding Structure for Compact Storage
Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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.
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.
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
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.
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
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.
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.
4Reliability
If safety protection devices are added to control the pedal, then user safety is improved, but device complexity increases
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.
