Solution Overview

Problem

Existing battery-operated vacuum cleaners often have a bulky design due to the protrusion of the battery device, which can pose safety risks and hinder compact storage.

Innovation Solution

The battery holder is positioned on the suction head between the process air duct and the top of the suction head, creating a recessed area that accommodates the battery device without protruding, allowing for a compact and space-saving design while ensuring easy access and removal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the battery device is mounted on the vacuum cleaner, then the vacuum cleaner can operate wirelessly, but the battery device protrudes and creates safety risks

Engineering Contradiction:
Improvewireless operation capabilityVSAvoidsafety risks from protruding battery
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The battery holder is nested within a receiving area formed by the bottom wall and rear wall on the suction head. The battery device is seated inside this recessed space, allowing it to be contained within the overall轮廓 of the vacuum cleaner without protruding outward, thus eliminating safety risks while maintaining wireless operation capability

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The battery holder is positioned in a three-dimensional space between the process air duct and the top of the suction head, utilizing vertical and lateral dimensions to create a recessed receiving area. This spatial arrangement allows the battery to be integrated into the vacuum cleaner's structure without protruding in any direction

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

2Volume of moving object

If the battery holder is positioned on the suction head, then the vacuum cleaner design becomes compact, but the battery device may interfere with other components

Engineering Contradiction:
Improveoverall compactnessVSAvoidcomponent interference
Core Design Contradiction:
Volume of moving objectVSDevice complexity

Solution Approach 1:

The receiving area is specifically positioned between the process air duct and the top of the suction head, utilizing a localized space that would otherwise be unused. The bottom wall and rear wall are strategically placed to delimit this area, ensuring the battery fits without interfering with the process air duct or other components while achieving compact overall design

Inventive Principle:
Principle #3Local quality
