Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If battery modules are designed with mechanical integrity through interconnections of all constituting parts, then structural stability is improved, but replacement of a submodule requires dismounting the whole battery module
Solution Approach 1:
The battery module is divided into independent submodules that can be individually removed. Each submodule is a self-contained unit with its own casing, allowing selective replacement without disassembling the entire battery module, thus resolving the contradiction between mechanical integrity and ease of repair.
Solution Approach 2:
The invention extracts the ability to remove individual submodules from the battery module structure. By designing submodules as separable units with standardized interfaces, the system allows extraction and replacement of only the defective submodule while maintaining the integrity of the remaining module structure.
2Power
If high-capacity battery modules are used to provide required energy density, then power output is improved, but the modules become expensive, large and heavy making storage and handling difficult
Solution Approach 1:
The battery system is segmented into multiple standardized submodules that can be individually handled and stored. This segmentation allows smaller, more manageable units to be stored in workshops and transported more easily, while still achieving high energy density when assembled into complete battery modules for vehicle installation.
Solution Approach 2:
The invention changes the operational parameters by allowing flexible configuration of battery capacity through different numbers and arrangements of submodules. This enables the system to be adapted to different energy density requirements while maintaining ease of storage and handling through standardized modular units.
3Productivity
If individual battery submodules are made detachable for easier replacement, then maintenance efficiency is improved, but mechanical integrity of the battery module may be compromised
Solution Approach 1:
The battery module is segmented into standardized submodules with defined mechanical interfaces. These interfaces are designed to maintain overall structural integrity while allowing individual submodule removal and replacement, thus achieving both high maintenance efficiency and preserved mechanical strength.
Solution Approach 2:
The submodule design incorporates universal mechanical interfaces and standardized mounting mechanisms that serve multiple functions: maintaining structural integrity when assembled, enabling easy individual removal for maintenance, and ensuring proper electrical and thermal connections. This multi-functionality resolves the contradiction between detachability and mechanical strength.
