Joined Channel Plate Structure for Stronger Vehicle Frame Joints
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing structures of joined channel-shaped plates in vehicle frames lack sufficient strength at the jointed sites, which can lead to structural weaknesses and potential failures under stress.
Innovation Solution
The structure involves extending flanges from channel-shaped plates and using a reinforcement plate to join them, where the extensions are positioned outside each other and the reinforcement plate is placed between them, enhancing the joint's strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If two channel-shaped plates are jointed together to form vehicle frame structures, then the structural configuration is achieved, but the jointed site lacks sufficient strength
Solution Approach 1:
The joint structure is segmented into multiple functional components: extensions protruding from the channel-shaped plates, reinforcement plates, and fastening elements. This segmentation allows each component to perform its specific function while collectively achieving high joint strength without excessive overall complexity
Solution Approach 2:
Extensions are pre-formed on the channel-shaped plates before assembly, protruding from the plate bodies in advance. This preliminary action prepares the joint interface for reinforcement plate attachment, enabling stronger connections without adding complexity during the final assembly process
Solution Approach 3:
Reinforcement plates serve as intermediary elements between the extensions of opposing channel-shaped plates. These intermediary components distribute and transfer loads across the joint interface, significantly enhancing joint strength while maintaining a manageable structural complexity through standardized plate components
2Strength
If extensions are positioned outside each other and reinforcement plate is placed between them, then joint strength is increased, but assembly complexity increases
Solution Approach 1:
Instead of attaching reinforcement plates to the outer surfaces of channel-shaped plates, the design inverts the approach by having extensions protrude from the plates and positioning reinforcement plates between these extensions. This inverted configuration achieves superior joint strength while simplifying the attachment process through direct fastening between extensions
Solution Approach 2:
The reinforcement plates are nested between the extensions of opposing channel-shaped plates, with extensions protruding from each plate and the reinforcement plate fitting within the space created by these protrusions. This nesting arrangement maximizes structural efficiency and simplifies assembly by containing all joint components within a compact interface region

AI summary
The disclosure herein provides a technique that provides increased strength to a jointed site of ends of two channel-shaped plates. A first (second) channel-shaped plate includes an elongated first (second) main plate, a first (second) upper flange, and a first (second) lower flange. The first channel-shaped plate includes a first extension at an end thereof, the first extension extending from the first lower flange and a lower part of the first main plate, and extending in a longitudinal direction of the channel-shaped plate. The second channel-shaped plate includes a second extension same as the first extension. The ends of the first and the second channel-shaped plates are assembled and joined such that the first extension is located outside the second channel-shaped plate and the second extension is located outside the first channel-shaped plate. A reinforcement plate is joined to both of the first main plate and the second main plate.
