Machine Tool Operation Panel Blower Layout for Noise Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operation panels for machine tools experience noise generation due to turbulent airflow produced by blower devices in limited spaces, which is not effectively addressed by existing technologies.
Innovation Solution
The operation panel incorporates a blower device with blade sections and a center axis section, along with an intermediate member between the blower device and an opposed wall, which occupies space to prevent turbulent flow and reduce noise. The intermediate member is preferably circular and connected to the opposed wall, eliminating the need for additional support structures and allowing for a compact design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a blower device is used for cooling in a limited space operation panel, then cooling function is improved, but noise is generated due to turbulent flow
Solution Approach 1:
An intermediate member is introduced between the opposed wall and the center axis section of the blower device. This intermediary component modifies the airflow path, preventing direct turbulent flow while maintaining the cooling function. The intermediate member acts as a mediator that smooths the air flow without compromising the blower's cooling performance.
2Object-generated harmful factors
If an intermediate member is added to reduce noise, then noise is restrained, but device complexity increases
Solution Approach 1:
The intermediate member is designed to serve multiple functions simultaneously: it reduces noise by preventing turbulent flow, maintains structural integrity within the limited space, and can be integrated with existing blower device components. This multi-functionality approach minimizes the need for additional separate components, thereby limiting the increase in device complexity.
3Volume of moving object
If the operation panel space is limited, then compact design is achieved, but turbulent flow is produced by the blower device
Solution Approach 1:
The intermediate member is strategically positioned in the specific region between the opposed wall and the center axis section where turbulent flow is most likely to occur. By locally modifying the airflow characteristics in this critical zone, the design maintains compact overall dimensions while effectively suppressing turbulent flow in the problematic area.
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
This configuration significantly reduces noise generated by the blower device while maintaining a compact and simplified internal structure, effectively addressing the issue of noise reduction in machine tool operation panels.
Implementation Method 1
the blower device sucking air in an axial direction about the predetermined axis and blowing out the air in the axial direction about the predetermined axis
Implementation Method 2
there is a possibility that turbulent flow is produced in the airflow. On this occasion, loud noise is generated due to the blowing by the blower device
Implementation Method 3
it is possible to restrain noise from being generated due to the blowing by the blower device
