Solution Overview

Problem

Existing dust collectors lack stability for temporarily placing power tools, leading to potential dropping issues when the tools are suspended, and there is a need for improved usability and accessory management.

Innovation Solution

A manually operable hook is integrated into the dust collector's housing, capable of rotating between retracted and pull-out positions, with a hooked end that projects sideward and can hold power tools and accessories securely, enhancing stability and storage convenience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the upper side of the main body is provided with a carrying handle for enhanced portability, then portability is improved, but the upper side has depressions and projections that prevent stable placement of power tools

Engineering Contradiction:
ImproveportabilityVSAvoidstability of power tool placement
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

The hook is designed to be movable between a retracted position (embedded in the housing profile) and a pull-out position (projecting sideward). This dynamic structure allows the upper surface to transition from a smooth portable state to a state with stable support for power tools, resolving the contradiction between portability and stability.

Inventive Principle:
Principle #15Dynamics

2Stability of the object's composition

If the hook projects sideward from the housing to hold power tools, then stability of power tool placement is improved, but the hook occupies space and adds structural complexity

Engineering Contradiction:
Improvestability of power tool placementVSAvoidstructural complexity of housing
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The hook is designed to be movable between a retracted position (embedded in the housing profile) and a pull-out position (projecting sideward). This dynamic structure allows the upper surface to transition from a smooth portable state to a state with stable support for power tools, resolving the contradiction between portability and stability.

Inventive Principle:
Principle #15Dynamics

3Reliability

If the hooked end portion is higher than the upper surface of the housing, then prevention of dropping is improved, but the hook requires more material and increases manufacturing complexity

Engineering Contradiction:
Improveprevention of droppingVSAvoidmanufacturing complexity
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The hook is designed to be movable between a retracted position (embedded in the housing profile) and a pull-out position (projecting sideward). This dynamic structure allows the upper surface to transition from a smooth portable state to a state with stable support for power tools, resolving the contradiction between portability and stability.

Inventive Principle:
Principle #15Dynamics

4Shape

If the hook is completely embedded in the housing profile when retracted, then aerodynamic efficiency and streamlined appearance are improved, but the hook cannot provide support for power tools

Engineering Contradiction:
Improvestreamlined appearanceVSAvoidsupport capability for power tools
Core Design Contradiction:
ShapeVSAdaptability or versatility

Solution Approach 1:

The hook is designed to be movable between a retracted position (embedded in the housing profile) and a pull-out position (projecting sideward). This dynamic structure allows the upper surface to transition from a smooth portable state to a state with stable support for power tools, resolving the contradiction between portability and stability.

Inventive Principle:
Principle #15Dynamics

AI summary

In a dust collector (1) including a main body (3) in which an air intake unit (5) is incorporated and a tank (2) over which the main body is disposed, a hook (17) is provided in a housing (4) of the main body (3), and capable of being manually operated to change a position thereof either to a retracted position in which the hook (17) is completely embedded in a profile of the housing (4) or a pull-out position in which the hook (17) projects sideward from the housing (4) with a hooked end portion (19) thereof oriented upward. A power tool (30) with its projected portion (32) disposed between the housing (4) and the hook end portion (19) of the hook (17) in the pull-out position can be stably supported on an upper surface of the housing (4) and on an upper end of the hooked end portion (19).
