Solution Overview

Problem

Existing cleaner holders are unable to stably charge and hold cleaners with a center of gravity on the upper side, as they require charging terminals on the upper side, which are not accommodated by conventional designs.

Innovation Solution

A cleaner holder with a charging stand body, support, and base, where the base includes an inner and auxiliary base to position the center of gravity close to the floor, and a multi-support structure to securely hold the cleaner, featuring a fastening unit and friction parts for stability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the charging terminal is provided on the upper side to charge cleaners with upper center of gravity, then the cleaner can be charged, but the holder cannot stably support the cleaner

Engineering Contradiction:
Improvecharging capabilityVSAvoidholder stability
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

The patent inverts the conventional charging terminal location from the upper side to the lower side of the holder. The charging terminal is now provided on the base rather than on an upper support structure, allowing the cleaner to be charged through contact at the lower insertion portion while maintaining stable support through the lower center of gravity design.

Inventive Principle:
Principle #13The other way round (Inversion)

Solution Approach 2:

The patent changes the spatial dimension of the charging interface by moving it from a vertical upper position to a horizontal lower position on the base. This dimensional repositioning allows the charging function to be integrated into the base structure rather than requiring elevated support elements.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Ease of operation

If the support structure is extended upward to reach upper charging terminals, then charging is enabled, but the support becomes more prone to damage

Engineering Contradiction:
Improvecharging functionVSAvoidsupport durability
Core Design Contradiction:
Ease of operationVSStrength

Solution Approach 1:

Instead of extending the support upward to reach the charging terminal, the patent inverts the approach by bringing the charging terminal down to the base level. This eliminates the need for vulnerable upward extensions while preserving the charging function through the lower insertion portion contact.

Inventive Principle:
Principle #13The other way round (Inversion)

Solution Approach 2:

The patent extracts the charging function from the upper support structure and relocates it to the base. This separation removes the structural burden from the support elements, allowing them to focus solely on mechanical support without the added complexity and vulnerability of integrated upper charging components.

Inventive Principle:
Principle #2Taking out (Extraction)

3Ease of manufacture

If the holder is designed for lower support insertion, then it works for cleaners with lower center of gravity, but it cannot accommodate cleaners with upper center of gravity requiring upper charging terminals

Engineering Contradiction:
Improvedesign simplicityVSAvoidcleaner type compatibility
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent creates a universal holder design where the base-mounted charging terminal can serve both cleaners with upper center of gravity and those with lower center of gravity. The lower insertion portion and base charging terminal configuration provides a common interface that adapts to different cleaner types without requiring design modifications.

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