Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional motor casings require external mounting brackets that complicate the assembly process, increase material usage, and lead to higher production costs and potential instability in mounting.
Innovation Solution
A motor casing design featuring a hollow body with integrated punched brackets and grooves, comprising a fixed, twisted connecting, and mounting part, allowing for a simpler, more reliable connection with reduced material usage and enhanced stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If external mounting brackets are used with welding or riveting, then connection reliability is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The mounting bracket is merged with the motor casing body into a single integrated component. The bracket is formed as an extension of the casing wall through punching operations, eliminating the need for separate bracket components and their associated fastening operations. This integration directly reduces device complexity while maintaining connection reliability through the monolithic structure.
Solution Approach 2:
The motor casing body serves multiple functions: it encloses the motor components and simultaneously provides mounting brackets for external device attachment. The integrated design makes the casing a multi-functional component that combines structural enclosure with mounting functionality, reducing the overall number of parts required in the system.
2Adaptability or versatility
If external mounting brackets with multiple connection methods are used, then adaptability is improved, but loss of substance increases
Solution Approach 1:
The mounting bracket and motor casing are merged into a single piece, eliminating the need for separate bracket materials and fastening materials (welding rods, rivets, or bolts). The bracket is formed from the same material as the casing through punching, directly reducing material consumption while maintaining mounting adaptability.
3Ease of operation
If threaded holes and bolts are used for mounting brackets, then ease of assembly is improved, but productivity decreases
Solution Approach 1:
The mounting brackets are pre-formed as integral parts of the motor casing during the casing manufacturing process itself. The punching operations that create grooves also create the brackets, so no separate bracket attachment step is needed. This preliminary formation of mounting features directly increases manufacturing productivity while maintaining ease of final assembly.
4Adaptability or versatility
If multiple separate components are used for brackets and mounting features, then adaptability is improved, but device complexity increases
Solution Approach 1:
The motor casing, mounting brackets, and grooves are merged into a single integrated structure. The bracket consists of a fixed part formed from the casing wall and a mounting part that extends outward, creating a unified component that provides both structural support and mounting functionality without requiring separate parts.

AI summary
A motor casing, including a hollow motor casing body. The wall of the motor casing body comprises a plurality of brackets and a plurality of grooves which are formed simultaneously by punching the wall of the motor casing body. The plurality of grooves is disposed one close to one of the brackets. One end of each bracket is coupled to the wall of the motor casing body. The motor casing has a simple structure, low cost, and reliable connection and requires less materials compared to conventional motor casings.
