Transmission Housing Frame Support for Material Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current transmission housing designs are inefficient in terms of material usage, as they distribute forces unevenly, leading to unnecessary material mass and potential instability.
Innovation Solution
A transmission housing design featuring a frame-shaped support section with varying rib configurations and thickened areas, where the frame-shaped support section absorbs and transmits high forces, allowing for thinner wall sections and reduced material usage while maintaining stability through strategically placed ribs and beams, and a housing cover for inspection and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If traditional housing designs distribute forces evenly throughout the entire housing structure, then structural stability is maintained, but material usage increases unnecessarily
Solution Approach 1:
The housing is divided into functionally distinct sections: a frame-shaped support section with high material density for force transmission, and wall sections with reduced material density for enclosure. This segmentation allows each part to have optimized material usage according to its specific functional requirements.
Solution Approach 2:
Different regions of the housing have different material densities and structural properties. The support section contains thickened areas and ribs with high material concentration where forces are transmitted, while the wall sections have thinner walls with reduced material content, creating local quality variations that optimize both strength and material efficiency.
2Loss of substance
If wall sections are made thinner to save material, then material usage decreases, but structural stability and force transmission capability worsen
Solution Approach 1:
The support section incorporates three-dimensional rib structures and thickened areas that extend in multiple directions, creating a spatial framework that provides structural stability without requiring thick walls throughout the entire housing. The ribs extend primarily in the vertical direction to resist gravitational and operational loads.
Solution Approach 2:
The housing combines different structural configurations within a single cast component: the frame-shaped support section with its rib structure and thickened areas is integrated with thinner wall sections, creating a composite structure that optimizes material distribution across different regions.
3Strength
If the support section contains more material for force transmission, then strength increases, but manufacturing complexity increases
Solution Approach 1:
The frame-shaped support section with its complex rib structure and thickened areas is manufactured as a single integrated cast component. This merging of multiple structural elements into one monolithic piece simplifies manufacturing by eliminating the need for separate fabrication and assembly steps, despite the complexity of the final structure.

AI summary
The invention relates to a housing for a transmission and to a transmission comprising a housing, the latter having an upper housing part and a lower housing part. The upper housing part has a frame-type supporting section, on which wall sections are formed and the frame-type supporting section having said wall sections is integrally formed, i.e. formed as one piece, in particular as a cast part and in particular as a cast steel part.
