Electric Motor Bracket Notch Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional structures and arrangements for supporting electric motors on vehicles are bulky, making it difficult to connect the motor to both electrical terminals and a driveshaft/transmission, resulting in unnecessary weight and limitations.
Innovation Solution
A vehicle design featuring a frame housing with a notch, a motor bracket, and an inverter, where the motor bracket fixes the electric motor to the frame housing, allowing for efficient connection to electrical and mechanical components while providing protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional frame housing is used to support the electric motor, then the motor is protected from damage, but the housing becomes bulky and heavy, making it difficult to connect the motor to electrical terminals and driveshaft/transmission
Solution Approach 1:
The frame housing is segmented by introducing a notch that divides the housing into separate sections. This segmentation allows the housing to be more compact while still providing protection, and facilitates easier connection of the motor to electrical terminals and driveshaft/transmission by creating access pathways through the segmented structure.
Solution Approach 2:
The notch is extracted from the frame housing, removing material from specific locations to create openings. This extraction reduces the overall bulk of the housing while maintaining protective functions, and enables connection access without requiring a completely separate connection structure.
2Reliability
If a conventional frame housing is used to support the electric motor, then the motor is protected from damage, but the housing results in unnecessary weight
Solution Approach 1:
By segmenting the frame housing through the notch, the structure uses material more efficiently. The housing provides protection only where needed while leaving openings for connections, reducing unnecessary material and thus weight, while maintaining essential protective functions.
3Reliability
If a conventional frame housing is used to support the electric motor, then the motor is protected from damage, but the housing creates limitations in connecting to electrical and mechanical components
Solution Approach 1:
The notch segments the frame housing to create distinct access zones, allowing electrical terminals and driveshaft/transmission connections to be made independently without interfering with each other or compromising motor protection. This segmentation provides flexibility for various connection configurations.
Solution Approach 2:
Material is extracted to form the notch, creating openings that enable connection access. This extraction provides the adaptability needed for flexible connection arrangements while the remaining housing structure continues to provide protection.

AI summary
A vehicle (10) includes an electric motor (103), a frame housing (102) including a notch (231), a motor bracket (104); and an inverter (106). The motor bracket (104) is provided between the electric motor (103) and the frame housing (102) and fixes the electric motor (103) to the frame housing (102). The frame housing (102) at least partially surrounds the electric motor (103), and the notch (231), which is defined in a portion of the frame housing (102), opposes the inverter (106).
