Vehicle Case Support Rib Layout for Transverse Rigidity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle transmission case support structures often lack sufficient rigidity in directions intersecting the longitudinal frame of the vehicle body, leading to vibration issues.
Innovation Solution
A vehicle design incorporating a case member, a stay member suspended between a boss part and a mount member, and a rib extending in the direction of the stay member's longitudinal direction at the root of the boss part, which increases rigidity by integrating the side cover, case, and mount bracket to form a robust support structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a stay member is added to increase rigidity in the transverse direction, then structural strength is improved, but device complexity increases
Solution Approach 1:
The patent integrates the rib directly into the case member as an integral structural feature rather than a separate component. This merging of the rib with the case member reinforces the transverse rigidity while minimizing the increase in device complexity, as the rib is formed as part of the existing case member structure.

AI summary
A vehicle includes a case member, a stay member and a rib. The case member is supported by a frame of a vehicle body with a mount member being interposed. The stay member is suspended between a boss part of the case member and a member of a case member side in the mount member, a longitudinal direction of the stay member intersecting a longitudinal direction of the frame. The rib extends in the case member in a direction that is an extension of the longitudinal direction of the stay member at a root of the boss part.
