Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If multiple battery modules are fixed together using a rigid frame structure, then the battery modules are securely held in place, but impact forces are transmitted between modules causing damage and safety hazards
Solution Approach 1:
The patent applies beforehand cushioning by incorporating a buffer component between adjacent battery modules in the fixing frame. This buffer component is specifically designed to absorb impact forces before they can be transmitted between modules. The buffer component includes a buffer body with elastic or viscous damping characteristics that are activated in advance to cushion against potential impacts, thereby protecting the battery modules from damage while maintaining their secure positioning.
2Strength
If a rigid connection structure is used to fix battery modules, then structural strength is improved, but the structure cannot absorb impact energy leading to module damage
Solution Approach 1:
The patent applies parameter changes by designing the buffer component with specific material and structural parameters that enable energy absorption. The buffer body is configured with controlled elasticity or viscosity parameters, and its geometric dimensions are optimized to provide appropriate cushioning characteristics. These parameter changes allow the fixing frame to maintain structural strength while introducing energy-dissipating properties that prevent impact energy from causing module damage.
3Productivity
If battery modules are closely arranged to maximize space utilization, then productivity is improved, but impact forces can propagate between adjacent modules
Solution Approach 1:
The patent applies the intermediary principle by introducing a buffer component as a mediator between adjacent battery modules. This buffer component serves as an intermediate element that physically separates the modules while allowing for compact arrangement. The buffer component absorbs and dissipates impact forces, preventing their propagation to adjacent modules, thereby enabling close spacing for high space utilization while maintaining safety performance through the protective intermediary function.
