Solution Overview

Problem

Existing cleaner support devices lack stability and ease of use, as they often fail to securely hold the cleaner during charging and can lead to battery detachment, and do not accommodate adjustable extension tubes effectively, resulting in inefficient cleaning and storage.

Innovation Solution

A support device with a charging stand body featuring spaced fixing parts with grooves for secure attachment of the cleaner, an adjustable extension tube for height adjustment, and a design that prevents battery detachment during separation, allowing for stable and convenient cleaning and storage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a simple protruding support piece structure 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 support device is divided into multiple functional components: a holder body for basic support, multiple fixing parts with fixing grooves for secure attachment, and a fixing protrusion on the cleaner that engages with these grooves. This segmentation allows each component to perform its specific function while working together to provide both simplicity and stability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The fixing protrusion of the cleaner is nested into the fixing grooves of the fixing parts, creating a interlocking structure. The fixing parts themselves are disposed on the holder body, creating a nested arrangement where smaller components fit within or on larger ones, providing secure fixation without complex mechanisms.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Ease of operation

If the cleaner is designed to be easily separated from the holder, then the ease of operation is improved, but the reliability of preventing battery detachment is reduced

Engineering Contradiction:
Improveseparation easeVSAvoidbattery retention
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

Different parts of the cleaner have different qualities: the cleaner body can be easily separated by lifting, but the battery is retained through a specific local feature (the fixing protrusion on the battery housing) that engages with the fixing grooves. This localized engagement ensures battery retention while allowing easy separation of the cleaner body.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

Instead of using complex locking mechanisms that require manipulation to release, the design uses gravity and simple vertical lifting motion for separation. The fixing structure works in reverse: normal weight keeps everything engaged, but upward motion naturally releases the cleaner body while the battery's protrusion prevents it from detaching.

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

3Adaptability or versatility

If the extension tube is made adjustable in length, then the adaptability is improved, but the device complexity increases

Engineering Contradiction:
Improvelength adjustabilityVSAvoidextension tube complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The extension tube transitions from a fixed structure to a dynamic, adjustable one. The telescopic design allows the tube to extend and retract, providing variable lengths for different cleaning needs. This dynamic capability is achieved through simple telescopic sections that slide within each other, maintaining relative simplicity while greatly improving adaptability.

Inventive Principle:
Principle #15Dynamics
