Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a complex composition including side sill is used to better performance against side collision, then collision resistance is improved, but production cost increases
Solution Approach 1:
The side sill is divided into multiple sections (front side sill, rear side sill) that are separately formed and then coupled together. Each section can be independently manufactured and optimized, allowing for simplified production while maintaining overall structural strength against side collisions.
Solution Approach 2:
The side sill incorporates an inner plate nested within an outer plate structure, creating a multi-layered configuration. This nested design provides enhanced collision resistance without requiring a completely separate internal structure, thereby controlling complexity while improving strength.
2Device complexity
If a simple composition is used, then production cost is reduced, but rigidity of side vehicle body cannot be ensured
Solution Approach 1:
The side sill employs a composite structure combining outer plate, inner plate, and connecting elements made from appropriate materials. This composite design achieves high rigidity and collision resistance through material selection and structural configuration rather than through complex assembly, maintaining simplicity while ensuring stability.
3Stability of the object's composition
If multiple partitions and cross members are added to enhance rigidity, then structural integrity is improved, but device complexity increases
Solution Approach 1:
The side sill structure integrates multiple functions into unified components. The outer plate and inner plate serve both as structural elements for rigidity and as collision-absorbing features. Cross members are strategically positioned to simultaneously provide structural support and facilitate load distribution, reducing the need for additional separate components.
Solution Approach 2:
Reinforcement and partitioning are applied locally at critical areas of the side sill where collision forces are most concentrated, rather than uniformly throughout the entire structure. This allows enhanced structural integrity at key locations while maintaining simplicity in less critical areas, optimizing the balance between strength and complexity.

AI summary
A side vehicle body reinforcing structure includes: at least two side sills connected to opposite ends of a center floor panel in a width direction of a vehicle body, respectively, and extending in a front and rear direction of the vehicle body, wherein each of the at least two side sills has a tube shape having an interior space therein; a seat cross member having a bottom side connected to the center floor panel and having opposite ends in the width direction of the vehicle body connected to the at least two side sills, respectively, so that the seat cross member crosses the center floor panel in the width direction of the vehicle body; and a center partition spaced apart from an outer plate of each of the at least two side sills to be toward the center floor panel, wherein the center partition has a “U” shape to be convex while being supported by an inner plate of each of the at least two side sills.
