Motor Drive Device Quick-Attach Support Plate
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional motor drive devices require numerous screws for securing, making attachment and detachment time-consuming and labor-intensive, especially for large or heavy devices, and increasing the number of parts involved.
Innovation Solution
The motor drive device is supported by a support plate with recessed parts and edge parts that interlock without the need for fastening members like screws, allowing for easy attachment and detachment by aligning and inserting the edge parts into corresponding recessed parts, reducing the number of components required.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screws are used to secure the motor drive device to the power magnetics cabinet, then the device can be firmly fixed, but the number of parts increases and attachment/detachment becomes time-consuming
Solution Approach 1:
The invention extracts and eliminates the screws (fastening members) from the securing mechanism. Instead of using separate fastening components, the support plate itself is designed with a pressing portion that directly contacts and secures the motor drive device housing, thereby reducing the number of parts while maintaining fixing firmness.
Solution Approach 2:
The invention merges the functions of the support plate and the fastening mechanism into a single integrated component. The pressing portion of the support plate combines the structural support function with the securing function, eliminating the need for separate screws and simplifying the overall structure.
2Reliability
If screws are used to secure the motor drive device, then the device can be firmly fixed, but attachment and detachment require lots of time and effort
Solution Approach 1:
By removing the screws and fastening operations, the invention drastically reduces the time required for attachment and detachment. The pressing portion provides sufficient securing force through direct contact, eliminating the time-consuming process of screwing and unscrewing multiple fasteners.
Solution Approach 2:
The pressing portion is designed to automatically engage with the motor drive device housing when the device is placed on the support plate. The structure itself provides the securing action without requiring additional fastening operations, making the attachment process self-service and time-efficient.
3Volume of moving object
If the motor drive device is large or heavy, then it can accommodate more components, but the number of screws required increases
Solution Approach 1:
The invention extracts the fastening members (screws) from the securing system regardless of device size. The pressing portion of the support plate provides adequate securing force for large or heavy motor drive devices through direct contact and structural design, eliminating the need to proportionally increase the number of screws with device size.
Solution Approach 2:
The invention changes the securing mechanism from a multi-point screw fastening system to a single pressing contact system. By modifying the pressing portion's area, material properties, or structural configuration, the support plate can accommodate larger and heavier devices without increasing the number of fastening parts.

AI summary
An apparatus with a motor drive device is provided with a support plate including an opening part for supporting the motor drive device. The support plate includes a first edge part around the opening part and a second edge part on the opposite side of the first edge part. The motor drive device includes a first recessed part formed on one end part in a predetermined direction, and a second recessed part formed on the other end part on the opposite side of the one end part. The first edge part is inserted into the first recessed part, and the second edge part is inserted to the second recessed part.
