Solution Overview

Problem

Conventional dirt suction devices have limited functionality and are cumbersome to use, particularly when switching between cleaning narrow gaps and larger surfaces, due to their fixed suction port design and lack of adaptability.

Innovation Solution

A dirt suction guide device with a tubular body, a movable part, and a coupling mechanism that allows the suction port to be opened or closed by sliding the movable part in and out, enabling the device to be angled and adjusted for different cleaning tasks, including a flexible first suction member and a rigid second suction member to manage airflow and pressure.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a fixed suction port design is used, then the device structure is simple, but the adaptability to different cleaning surfaces is poor

Engineering Contradiction:
Improveadaptability to different cleaning surfacesVSAvoiddevice structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The suction guide device incorporates a movable part that can slide between extension and contraction positions, transforming the fixed structure into a dynamic one. This allows the device to adapt its shape and size according to different cleaning surfaces, resolving the contradiction between simplicity and adaptability.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The device is designed to perform multiple functions by combining a crevice function (when contracted) and a general suction function (when extended). The single device can clean both narrow gaps and larger surfaces, eliminating the need for multiple specialized accessories.

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

2Adaptability or versatility

If multiple specialized accessories are used to clean different surfaces, then the adaptability is improved, but the device complexity and number of parts increases

Engineering Contradiction:
Improvecleaning capability for different surfacesVSAvoidnumber of accessories
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The invention merges the functions of multiple specialized accessories (crevice tool and general suction nozzle) into a single device. By integrating both functions into one guide device with a movable part, users no longer need to replace between multiple accessories, simplifying the overall system while maintaining versatility.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The suction guide device is designed as a universal tool that can clean various surfaces including narrow gaps, floors, and fabrics. The movable part enables the device to switch between different cleaning modes, making one accessory sufficient for multiple cleaning tasks.

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

3Area of stationary object

If the movable part is extended to increase cleaning region, then the adaptability is improved, but the suction port closes

Engineering Contradiction:
Improvecleaning regionVSAvoidsuction capability
Core Design Contradiction:
Area of stationary objectVSProductivity

Solution Approach 1:

The device employs different flow paths for different operating modes: when the movable part is extended, the first flow path is activated for general surface cleaning; when contracted, the second flow path is activated for crevice cleaning. This local differentiation of flow paths ensures optimal suction performance for each cleaning scenario.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The movable part dynamically changes position between extension and contraction, which simultaneously changes the cleaning region and activates different flow paths. This dynamic adjustment ensures that the suction port remains open and functional in both extended and contracted states, resolving the contradiction between cleaning region and suction capability.

Inventive Principle:
Principle #15Dynamics

4Productivity

If the movable part is contracted to maintain suction port open, then the suction capability is maintained, but the cleaning region is limited

Engineering Contradiction:
Improvesuction capabilityVSAvoidcleaning region
Core Design Contradiction:
ProductivityVSArea of stationary object

Solution Approach 1:

The movable part can dynamically switch between contracted and extended positions based on cleaning needs. When contracted, it maintains open suction port for strong suction in narrow gaps; when extended, it increases the cleaning region for larger surfaces. This dynamic capability allows the device to optimize for either suction capability or cleaning region as needed.

Inventive Principle:
Principle #15Dynamics
