Solution Overview

Problem

Existing blowers require a separate container for water when used as a sprayer, which complicates handling and convenience.

Innovation Solution

An electric blower with a built-in sprayer attachment that includes a container, nozzle, and liquid supply passage, allowing the blower to be used as a sprayer without the need for a separate container, with features like adjustable nozzle positions and a holder for stable attachment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a separate container is used for water when the blower is used as a sprayer, then the blower can fulfill an additional spraying function, but the handling convenience deteriorates due to carrying the container separately from the blower

Engineering Contradiction:
Improvespraying functionVSAvoidhandling convenience
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The container is integrated with the blower body to form a single unified structure. The container is positioned within the housing of the blower, and the liquid supply passage connects the container to the nozzle, allowing the blower to function as both an air blower and a sprayer without requiring separate carrying of components.

Inventive Principle:
Principle #5Merging (Combining)

2Ease of operation

If the container and nozzle are attached to the blower body, then the sprayer attachment can be carried integrally with the blower, but the device complexity increases

Engineering Contradiction:
Improveintegrated carryingVSAvoidattachment structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The blower body is designed with mounting structures that allow the container and nozzle to be attached as an integrated sprayer attachment. The housing includes a container receiving space and mounting features for the nozzle, enabling the same blower to perform both blowing and spraying functions through a unified attachment system.

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