Solution Overview

Problem

Existing cleaner holders cannot simultaneously charge both the cleaner device and its detachable battery, leading to inconvenience when the battery discharges during use, as they typically require separate charging and do not provide stable support for the cleaner.

Innovation Solution

A cleaner holder design featuring a first body with a charging port for the cleaner and a second body with a recessed battery accommodating space, including a second charging port, allowing for simultaneous charging of both the cleaner and its battery, with a cleaner guide to ensure proper contact and stable support.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the holder only charges the cleaner body, then the charging structure is simple, but the battery cannot be charged separately causing user inconvenience

Engineering Contradiction:
Improvecharging capabilityVSAvoidholder structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The holder is divided into functionally independent charging areas: a first charging area with a first charging terminal for the cleaner body, and a second charging area with a second charging terminal for the battery. This segmentation allows each area to operate independently, enabling versatile charging options while maintaining a relatively simple overall structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The holder is designed to perform multiple charging functions simultaneously - it can charge the cleaner body alone, charge the battery alone, or charge both together. The first and second charging terminals are both connected to the power supply module, enabling the holder to serve as a universal charging station for different components of the cleaning system.

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

2Adaptability or versatility

If the holder accommodates both cleaner and battery charging functions, then charging versatility improves, but the holder width increases

Engineering Contradiction:
Improvecharging capabilityVSAvoidholder width
Core Design Contradiction:
Adaptability or versatilityVSLength of stationary object

Solution Approach 1:

The battery accommodating space is designed to extend in the width direction of the holder, utilizing the width dimension efficiently. The battery can be placed horizontally in the second charging area, allowing the holder to accommodate both charging functions without significantly increasing overall width beyond what is already utilized by the cleaner body charging area.

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

3Ease of operation

If the battery accommodating space is exposed, then battery accessibility is good, but the holder appearance is bulky

Engineering Contradiction:
Improvebattery accessibilityVSAvoidholder compactness
Core Design Contradiction:
Ease of operationVSShape

Solution Approach 1:

The battery accommodating space is nested within the holder body as a recessed cavity in the second charging area. This nesting approach allows the battery to be stored compactly within the holder's overall form, maintaining a sleek appearance while still providing easy access through the open top of the accommodating space.

Inventive Principle:
Principle #7Nested doll (Nesting)
