Solution Overview

Problem

Existing cleaner holders struggle to stably fix vacuum cleaners due to inadequate support mechanisms, particularly in holding the upper and lower sides, leading to instability during charging.

Innovation Solution

A cleaner holder with a locking part that rotates to securely fix the cleaner by coupling with the battery housing and dust container, using link members and elastic members for easy operation and enhanced stability, allowing simultaneous fixation of both sides.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a simple protruding support piece is used to hold the cleaner, then the device complexity is reduced, but the stability of the cleaner is insufficient

Engineering Contradiction:
Improvestructure complexityVSAvoidcleaner stability
Core Design Contradiction:
Device complexityVSStability of the object's composition

Solution Approach 1:

The fixing mechanism is divided into multiple independent components: a locking part with link members for the upper side, and a separate fixing member with fixing bosses for the lower side. This segmentation allows each component to perform its specific function effectively, providing stable fixation while maintaining reasonable structural complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The link members are rotatably coupled to the locking part and work in a nested manner within the holder body. The fixing bosses are inserted into fixing grooves, creating a nested structure that provides stable fixation. This nesting approach allows compact design while ensuring reliable cleaner holding.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Stability of the object's composition

If a locking mechanism with multiple link members and elastic members is added to fix the cleaner, then the stability of the cleaner is improved, but the device complexity increases

Engineering Contradiction:
Improvecleaner stabilityVSAvoidstructure complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The locking part is designed to be rotatable, allowing dynamic adjustment and engagement with the cleaner. The link members can rotate and adapt to the cleaner's position, providing stable fixation while maintaining ease of operation. This dynamic design reduces the need for overly complex rigid structures.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The elastic member automatically engages the locking part with the cleaner without requiring additional actuators or complex control mechanisms. The self-servicing locking mechanism provides stable fixation through the natural elastic force, reducing overall device complexity while ensuring reliable cleaner holding.

Inventive Principle:
Principle #25Self-service

3Ease of operation

If a separate locking part is added to fix the cleaner, then the ease of operation is improved through easy mounting and dismounting, but the device complexity increases

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

Solution Approach 1:

The rotatable locking part with link members enables easy mounting and dismounting operations. Users can simply rotate the locking part to engage or disengage the cleaner, providing intuitive and convenient operation. This dynamic mechanism achieves ease of use without requiring complex control systems.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The link members act as intermediaries between the locking part and the cleaner, facilitating easy engagement and disengagement. The fixing bosses and grooves serve as intermediary elements that guide the cleaner into the correct position and secure it automatically, reducing the operational complexity for users.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A cleaner holder includes: a first body having a charging port to charge a cleaner; a second body connected to the first body, configured to support the cleaner and having an accommodation space in which a battery is accommodated; and a locking part rotatably connected to the first body and configured to fix the cleaner, wherein when force having predetermined magnitude is applied to the locking part in one direction, the locking part is rotated in a first direction to be coupled to the cleaner, so that the cleaner is fixed, and wherein when force having predetermined magnitude is applied to the locking part in the other direction, the locking part is rotated in a second direction opposite to the first direction to be uncoupled from the cleaner.
