Solution Overview

Problem

Existing floor cleaning devices have a large control switch that occupies significant space at the top of the brush head, resulting in a higher overall device height.

Innovation Solution

A floor brush structure with a brush connector, brush head, and trigger control mechanism, where the brush connector rotates relative to the brush head to drive a triggering element, which in turn triggers a triggered element to stop the cleaning device, all housed within a compact receiving chamber.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a large control switch is used to stop the cleaning device, then the control function is reliable, but the support frame occupies large space and increases the overall device height

Engineering Contradiction:
Improvecontrol function reliabilityVSAvoidoverall device height
Core Design Contradiction:
ReliabilityVSLength of stationary object

Solution Approach 1:

The patent extracts the control switch from the traditional support frame structure and relocates it to the brush head body. This separation allows the control switch to be positioned in a compact space within the brush head, eliminating the need for a large support frame and thereby reducing the overall device height while maintaining control reliability

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The control switch is moved from a vertical arrangement (requiring height) to a horizontal arrangement within the brush head body. By utilizing the lateral space within the brush head instead of vertical space, the patent achieves compact control functionality without increasing device height

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

2Ease of operation

If a large support frame is used to accommodate the control switch, then the control switch can be easily accessed, but the space at the top of the brush head is occupied and the device height increases

Engineering Contradiction:
Improvecontrol switch accessibilityVSAvoidspace occupation at brush head top
Core Design Contradiction:
Ease of operationVSArea of stationary object

Solution Approach 1:

The control switch is merged with the brush head body structure, becoming an integrated component rather than a separate element. This consolidation eliminates the need for additional support frames and reduces the space occupation at the top of the brush head while maintaining operational accessibility

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The brush head body serves multiple functions: it houses the brush elements for cleaning and simultaneously accommodates the control switch mechanism. This multi-functionality eliminates the need for separate support structures, reducing overall space requirements

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