Draw Beam End Flange Segmentation for Vertical Offset Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing draw beams for heavy towing vehicles face challenges in adaptability, as vertical fastening lugs provide stability but restrict design options and make it difficult to fit various vertical offset positions relative to the longitudinal main beams.
Innovation Solution
A draw beam design featuring first and second parallel walls with a U-beam web, where end flanges are perpendicular and have fastening holes in specific planes, allowing for adjustable mounting positions and enhanced stability without overlapping, enabling better alignment with longitudinal main beams and improved stress reduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If vertical fastening lugs are provided on the draw beam, then the web stability is improved and movement is reduced, but the adaptability to fit various vertical offset positions deteriorates
Solution Approach 1:
The draw beam is segmented into three distinct end flange components: a first wall end flange, a second wall end flange, and a web end flange. Each flange can be independently positioned and fastened to the longitudinal main beams at different vertical locations. This segmentation allows the web to be stabilized by the web end flange while the wall end flanges provide additional mounting position options, thus resolving the contradiction between web stability and adaptability to various vertical offset positions.
2Strength
If vertical fastening lugs are provided on the draw beam, then the stress in the draw beam is reduced, but the design options are restricted
Solution Approach 1:
The draw beam is segmented into three distinct end flange components: a first wall end flange, a second wall end flange, and a web end flange. Each flange can be independently positioned and fastened to the longitudinal main beams at different vertical locations. This segmentation allows the web to be stabilized by the web end flange while the wall end flanges provide additional mounting position options, thus resolving the contradiction between web stability and adaptability to various vertical offset positions.
3Ease of manufacture
If the draw beam is designed with fixed mounting positions, then the manufacturing is simplified, but the ease of operation for various mounting positions deteriorates
Solution Approach 1:
The draw beam is segmented into three distinct end flange components: a first wall end flange, a second wall end flange, and a web end flange. Each flange can be independently positioned and fastened to the longitudinal main beams at different vertical locations. This segmentation allows the web to be stabilized by the web end flange while the wall end flanges provide additional mounting position options, thus resolving the contradiction between web stability and adaptability to various vertical offset positions.
Solution Approach 2:
The draw beam design incorporates multiple end flanges that serve multiple functions: the web end flange provides web stabilization, while the first and second wall end flanges provide additional mounting position options. This multi-functionality allows a single draw beam design to accommodate various vertical offset positions and mounting configurations, improving ease of operation without significantly complicating manufacturing.
