Hybrid Engine Motor Support Bracket and Tension Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional engine support structures are insufficient to handle the weight and size of high-capacity electric motors required in industrial hybrid engines, necessitating a stronger support mechanism.
Innovation Solution
An endless rotary band transmission system with a support bracket and tension mechanism is used to securely attach and tension the electric motor, allowing for robust support of large and heavy electric motors while maintaining compactness and cost-effectiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a conventional alternator support structure is used, then the structure is simple and compact, but it is insufficient to support the weight and size of high-capacity electric motors
Solution Approach 1:
The support structure is divided into multiple components: a support bracket that mounts to the engine block, a separate tension mechanism with its own mounting, and an electric motor mounting bracket. This segmentation allows each component to be optimized for its specific function while distributing the structural load, resolving the contradiction between needing stronger support and maintaining structural simplicity.
Solution Approach 2:
A support bracket is introduced as an intermediary component between the engine block and the electric motor. This intermediary structure provides the necessary strength support for the heavy electric motor while keeping the overall design manageable and modular, avoiding the need for a completely complex integrated structure.
2Reliability
If the electric motor is securely mounted with a tension mechanism, then the motor is firmly supported, but the engine layout becomes less compact
Solution Approach 1:
The support bracket serves multiple functions: it mounts the electric motor to the engine block, provides structural support, and integrates with the tension mechanism mounting. By merging these functions into a single integrated component, the design achieves reliable mounting without requiring separate structures that would increase engine layout volume.
Solution Approach 2:
The support bracket is designed as a multi-functional component that simultaneously provides motor mounting, structural support, and tension mechanism anchoring. This universality reduces the total number of components and space required, maintaining compact engine layout while ensuring reliable motor support.
3Reliability
If a separate tension mechanism is provided, then the endless rotary band is properly tensioned, but additional components are required
Solution Approach 1:
The tension mechanism is integrated with the support bracket structure, sharing mounting points and structural elements. This merging reduces the number of separate components while maintaining reliable belt tensioning, as the tension mechanism leverages the existing support infrastructure rather than requiring entirely independent mounting.
Solution Approach 2:
The support bracket is designed to universally support both the electric motor and the tension mechanism, providing mounting points and structural support for both components. This multi-functionality reduces the total component count while ensuring reliable tensioning of the endless rotary band.

AI summary
In an industrial hybrid engine, an endless rotary band wound around a drive pulley of a crankshaft and a motor pulley of an electric motor for power is provided. The electric motor is attached to an engine body by using a support bracket. A tension mechanism is supported by the support bracket, the tension mechanism tensioning the endless rotary band in a direction in which the endless rotary band is stretched. A second support bracket that supports the electric motor separately from the support bracket is provided.
