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, allows for simultaneous charging of both the cleaner and its battery, with a cleaner guide ensuring proper alignment and support, reducing the device's width and improving stability.

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 is improved, but the device width increases

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

Solution Approach 1:

The second charging terminal extends along the width direction of the holder, utilizing the width dimension efficiently. The battery charging port is arranged along the width direction to match the terminal orientation, allowing the battery to be placed horizontally in the second charging area. This dimensional arrangement accommodates dual charging functions while minimizing overall width increase.

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

3Reliability

If the cleaner guide is not provided, then the holder structure is simpler, but the cleaner terminal alignment with charging port is unreliable

Engineering Contradiction:
Improveterminal alignmentVSAvoidholder structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The cleaner guide structure passively guides the cleaner body into the correct position during insertion. The guide utilizes the cleaner's own weight and insertion motion to automatically align the cleaner terminal with the first charging port, eliminating the need for complex active alignment mechanisms while ensuring reliable electrical connection.

Inventive Principle:
Principle #25Self-service
