Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If battery units are permanently integrated into the vehicle structure, then structural stability is improved, but replacement time and operational downtime increase significantly
Solution Approach 1:
The battery system is divided into modular battery units that can be independently removed and replaced. Each battery unit is a self-contained module with standardized interfaces, allowing individual units to be swapped without affecting the overall vehicle structure or requiring replacement of the entire battery system.
Solution Approach 2:
The bracket system transitions from a fixed permanent integration to a dynamic removable connection. The bracket with standardized fastening interfaces enables the battery module to be easily attached and detached, transforming the static structural integration into a flexible, changeable configuration that balances structural stability with rapid replaceability.
2Ease of operation
If battery modules are made lightweight for easier handling, then ease of operation is improved, but structural strength and safety may be compromised
Solution Approach 1:
The battery system is divided into smaller modular units that can be individually handled and replaced. This segmentation reduces the weight and size of each individual battery module, making them easier to manipulate while maintaining the overall capacity through multiple units.
Solution Approach 2:
The bracket system provides dynamic mechanical assistance during battery module installation and removal. The standardized fastening interfaces and mounting structures reduce the physical effort required for handling, allowing operators to easily secure and release battery modules without excessive manual force.
3Adaptability or versatility
If extensive structural modifications are made to accommodate battery modules, then adaptability is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The bracket system is designed as a universal mounting structure that can accommodate different battery unit configurations and sizes. The standardized fastening interfaces and modular design allow the same bracket structure to serve multiple functions and adapt to various battery module arrangements without requiring custom structural modifications for each application.
4Reliability
If battery units are securely fastened to prevent movement, then reliability is improved, but ease of replacement deteriorates
Solution Approach 1:
The fastening system transitions from a permanent fixed connection to a dynamic reversible connection. The standardized fastening interfaces allow battery units to be securely held during operation while enabling quick and tool-free removal when needed. The mechanical design provides reliable engagement during use but allows easy disengagement for replacement.
