Vehicle Frame Joint Block Assembly for Dimensional Variation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle skeleton structures face difficulties in accommodating skeletal components that exceed prescribed dimensions due to variations in the distance between side members, making it challenging to attach such components securely.
Innovation Solution
A vehicle skeleton structure with a frame comprising side members, cross members, and joint blocks, where the joint blocks include adhesive surfaces and injection grooves that allow for the accommodation of dimensional variations by bonding and fixing the skeletal components before adhesive injection, using the adhesive to spread over the entire circumference and absorb excess dimensions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If mechanical joining is used to connect skeletal members, then the structure is simple and easy to manufacture, but it cannot accommodate variations in the distance between side members when attaching skeletal components
Solution Approach 1:
The joint block serves as an intermediary component between the side member and the skeletal component. It includes an adhesive surface that contacts the skeletal component and an insertion portion that fits into the side member opening, enabling it to bridge the gap between fixed frame dimensions and variable component dimensions.
Solution Approach 2:
The patent changes the joining method from purely mechanical (bolts) to chemical bonding (adhesive). The adhesive surface allows the joint block to bond with the skeletal component, enabling accommodation of dimensional variations through the adhesive layer thickness and flexibility.
2Stability of the object's composition
If the distance between side members is fixed, then the frame structure is stable and rigid, but skeletal components with dimensional variations cannot be attached
Solution Approach 1:
The connection system is segmented into three distinct parts: the fixed side member, the adaptive joint block, and the variable skeletal component. This segmentation allows the joint block to serve as a buffer zone that absorbs dimensional variations while maintaining overall structural stability.
Solution Approach 2:
The joint block acts as a mediator between the rigid frame and the variable skeletal component. Its adhesive surface and insertion portion design enable it to compensate for distance variations without compromising the stability of the overall frame structure.
3Adaptability or versatility
If adhesive surfaces are added to accommodate dimensional variations, then adaptability improves, but the device complexity increases
Solution Approach 1:
The joint block merges multiple functions into a single component: structural connection, dimensional adjustment, and adhesive bonding. By combining these functions, the patent avoids the need for separate adjustment mechanisms, thereby limiting the increase in device complexity.
Solution Approach 2:
The joint block is designed as a universal component that can accommodate various skeletal components with different dimensions. The adhesive surface and insertion portion configuration enable it to perform multiple functions: mechanical support, dimensional compensation, and secure bonding.

Function Achieved in This Case
The structure effectively accommodates skeletal components exceeding prescribed dimensions by adjusting and securing them to the frame, ensuring stable attachment and alignment through adhesive bonding, thereby enhancing the assembly process and structural integrity.
Implementation Method 1
The joint block is provided with an adhesive surface along the vehicle width direction. The adhesive surface accommodates variations between the abutment surfaces of the skeletal component.
