Vehicle Sub-Frame Assembly with Triangular Mount Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sub-frame assemblies for vehicles with unibody designs often require more than four body mounts, making them heavier, harder to handle, and more costly to attach and detach, while sacrificing strength and durability.
Innovation Solution
A sub-frame assembly with exactly three body mounts arranged in a triangular pattern, featuring longitudinal members and a cross-member with single body mounts each, and a plurality of link brackets for suspension components, reducing the number of fasteners needed and enhancing structural integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If more than four body mounts are used in sub-frame assemblies, then strength and durability are improved, but weight increases and handling becomes more difficult
Solution Approach 1:
The patent changes the key parameter from the number of body mounts (4 or more) to exactly three body mounts. This parameter change reduces weight and simplifies handling while the triangular arrangement and structural design of the sub-frame members maintain the necessary strength and durability requirements.
2Strength
If more than four body mounts are used in sub-frame assemblies, then strength and durability are improved, but ease of attachment and detachment deteriorates
Solution Approach 1:
The patent changes the number of body mounts from four or more to exactly three, which directly reduces the number of fasteners required for attachment and detachment. This parameter change improves ease of operation while the triangular configuration maintains structural integrity.
3Strength
If more than four body mounts are used in sub-frame assemblies, then strength and durability are improved, but device complexity increases
Solution Approach 1:
The patent simplifies the device by changing the number of body mounts from four or more to exactly three. This parameter change reduces device complexity while the triangular arrangement and optimized sub-frame member design maintain the required strength and durability.

AI summary
A sub-frame assembly for attachment to a unibody of a vehicle and for supporting at least one vehicular component is provided. The sub-frame assembly includes a pair of longitudinal members which are spaced from one another in a lateral direction and extend in a longitudinal direction between first and second ends. The longitudinal members at least partially converge towards one another from the first ends to the second ends such that the second ends are closer to one another than the first ends. A cross-member is coupled with and extends laterally between the longitudinal members. Each of the longitudinal members and the cross-member has a single and no more than one body mount for connection with the unibody of the vehicle such that the sub-frame assembly has exactly three body mounts in total.
