Fan Fixing Member With Regulating Hook For Motor Drive Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional motor drive devices require extensive working hours and risk wiring mistakes during maintenance due to the need to remove the entire device to access and replace the fan motor, which is cumbersome and prone to errors, especially in environments with cutting oil mist and fine particles.
Innovation Solution
A motor drive device design that incorporates a fan fixing member with a regulating member, such as a hook or slide member, which allows for secure fastening and easy removal of the fan unit without the need to remove screws from multiple locations, reducing the complexity and time required for maintenance operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the fan unit is fixed to the mounting member using multiple screws at multiple locations, then the fixing reliability is improved, but the maintenance complexity and time required increase
Solution Approach 1:
The fan fixing member is divided into multiple independent fixing portions, each capable of being fastened separately. This segmentation allows maintenance personnel to access and remove individual screws from different directions, significantly improving maintenance operability while maintaining reliable fixation through the distributed fixing portions
Solution Approach 2:
The fixing portions are arranged in multiple directions (upward, downward, leftward, rightward) relative to the fan unit. This spatial distribution in multiple dimensions enables access to screws from various angles, reducing maintenance complexity while ensuring robust fixation through multi-directional anchoring
2Strength
If the fan unit is fixed using multiple screws at multiple locations, then the fixing strength is improved, but the device complexity increases
Solution Approach 1:
The fan fixing member serves multiple functions simultaneously: it supports the fan unit, provides sealing against cutting fluid mist, and enables easy maintenance through its modular fixing portions. This multi-functionality reduces the need for separate components, thereby reducing overall device complexity while maintaining strong fixation
Solution Approach 2:
The fan fixing member integrates the fan support function with the sealing function and the fastening function into a single component. By merging these functions, the patent reduces the number of separate parts needed, simplifying the overall structure while ensuring strong and reliable fixation

AI summary
A motor drive device that closes a mounting hole for mounting a fan unit by way of a fan fixing member is provided with a structure that can effectively improve operability for maintenance. A bar serving as a regulating member of a motor drive device has a first projecting piece that is formed so as to curve downwards after extending in the horizontal direction from a top part thereof, and a second projecting piece that projects downwards from a bottom part thereof, and by the first projecting piece being placed in an upper insertion part and the second projecting piece being placed in a lower insertion part, a fan unit is fixed in a mounting hole of a flange.
