Engine Mount Bracket Layout for Even Stress Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mount structures for internal combustion engines fail to adequately distribute stress caused by vehicle acceleration and deceleration, leading to potential concentration of stress on the engine.
Innovation Solution
A mount structure comprising a first and second mount bracket with specific fastening positions and configurations, including columnar fastening portions and a base portion with penetrating portions, to distribute stress more evenly across the engine.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single mount bracket is used to connect the engine to the vehicle body, then the structure is simple, but stress concentrates on the engine during acceleration and deceleration
Solution Approach 1:
The mount structure is divided into a first mount bracket connected to the engine and a second mount bracket connected to the vehicle body. These two brackets are positioned at different locations and connected through a mount, creating a segmented structure that distributes stress away from the engine while maintaining structural simplicity.
2Area of stationary object
If fastening positions are placed close together on the mount bracket, then the bracket structure is compact, but stress distribution is poor during vehicle acceleration and deceleration
Solution Approach 1:
The first and second mount brackets are positioned at different spatial locations and orientations. The first bracket extends in a first direction while the second bracket extends in a second direction different from the first, creating a multi-dimensional stress distribution pattern that improves stress distribution without increasing the overall footprint area.

AI summary
A mount structure of an internal combustion engine includes a first mount bracket fastened to an internal combustion engine at a first fastening position and a second fastening position, and a second mount bracket fixed to a mount attached to a vehicle body on which the internal combustion engine is mounted and fastened so as to overlap the first mount bracket at a third fastening position and a fourth fastening position that are separated from each other by an interval between the first fastening position and the second fastening position.
