Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a plate defining outer peripheries of secondary batteries is used, then structural support is provided, but external impact cannot be absorbed and internal elements may be damaged
Solution Approach 1:
The patent applies beforehand cushioning by incorporating a buffer between the end plate and the batteries/elements. This buffer is positioned in advance to absorb external impacts before they can reach and damage the internal elements such as bus bars and connectors. The buffer acts as a pre-positioned protective layer that mitigates harmful forces.
Solution Approach 2:
The buffer serves as an intermediary element between the end plate and the internal components (batteries, bus bars, connectors). It mediates the transmission of external forces, absorbing impact energy and preventing direct contact between the external environment and sensitive internal elements, thereby protecting them from damage.
2Reliability
If elements such as bus bar or connector are exposed to electrically connect batteries, then electrical connection is achieved, but elements are vulnerable to external impact
Solution Approach 1:
The patent applies nesting by placing the electrical elements (bus bars and connectors) inside the battery module, nested within the protective structure formed by the end plate and buffer. This nested arrangement allows electrical connections to be maintained while the elements are protected from external impacts by the surrounding protective layers.
Solution Approach 2:
The buffer acts as an intermediary protective layer that surrounds and protects the electrical elements (bus bars and connectors) from external impacts. This intermediary structure allows the elements to perform their electrical connection function while being shielded from harmful external forces.
3Stability of the object's composition
If end plate is disposed outside batteries, then outer periphery is defined, but impact protection is insufficient
Solution Approach 1:
The patent enhances impact protection by adding a buffer layer between the end plate and the batteries, creating a beforehand cushioning system. This buffer is positioned in advance to absorb external impacts, allowing the end plate to maintain its structural stability while the buffer handles the impact absorption function.
Solution Approach 2:
The protective structure becomes a composite system combining the rigid end plate (for structural stability) with the cushioning buffer (for impact absorption). This composite arrangement allows each component to perform its optimal function - the end plate provides structural definition and stability, while the buffer provides impact protection.
