Electric Hammer with Integrated Dust Collection Fan and Channel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric hammers require an external dust collection device for dust collection, which involves time and effort.
Innovation Solution
An electric hammer with a built-in dust collection system, including a motor, striker assembly, dust collection fan, and dust collector, that generates a suction force to collect dust without the need for an external device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If an external dust collection device is used, then dust collection function is achieved, but device complexity and ease of operation deteriorate due to additional connection requirements
Solution Approach 1:
The dust collection device is merged with the electric hammer body, integrating the dust collection fan, dust collector, and dust collection channel into a single unified device. This eliminates the need for separate external dust collection equipment and simplifies the overall system while maintaining effective dust collection functionality.
Solution Approach 2:
The electric hammer is designed with multi-functionality by incorporating both the striking function and dust collection function into a single device. The dust collection fan and dust collector enable the hammer to perform dust collection during operation, making the device universal and reducing the need for additional external equipment.
2Object-affected harmful factors
If an external dust collection device is used, then dust collection function is achieved, but ease of operation worsens due to connection time and effort
Solution Approach 1:
By merging the dust collection device with the electric hammer body, the system eliminates the need for separate connection steps. The integrated design allows users to operate both the hammer and dust collection functions simultaneously without the time and effort required to connect external devices, significantly improving ease of operation.
3Ease of operation
If a built-in dust collection system is used, then ease of operation improves, but device complexity increases
Solution Approach 1:
The built-in dust collection system is segmented into distinct functional modules: the dust collection fan for generating suction, the dust collection channel for guiding dust flow, and the dust collector for storing collected dust. This modular segmentation manages internal structure complexity by organizing components into clear functional units while maintaining ease of operation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables efficient dust collection directly within the electric hammer, improving workability and reducing the need for external equipment, while maintaining balance and ease of maintenance.
Implementation Method 1
a dust collection fan rotatable in response to the motor being driven; a dust collection channel having a suction port being open toward a tip of the bit, the dust collection channel being configured to generate a suction force in the suction port in response to rotation of the dust collection fan

AI summary
An electric hammer can collect dust without using an external dust collection device. An electric hammer includes a motor, a body incorporating the motor, a striker assembly operable in response to the motor being driven to strike a bit attached along a striking axis, a dust collection fan rotatable in response to the motor being driven, a dust collection channel having a suction port being open toward a tip of the bit to generate a suction force in the suction port in response to rotation of the dust collection fan, and a dust collector located on the dust collection channel to collect dust sucked through the suction port.
