Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a single cylindrical battery cell is used, then the device structure is simple, but the output power is insufficient (less than 4W) and use time is limited
Solution Approach 1:
The battery module is divided into multiple cylindrical battery cells (first, second, third, and fourth cells) arranged in series within the shrinkable tube. This segmentation allows each cell to contribute to the total output power, achieving 4W or greater while maintaining a manageable structural complexity through modular arrangement.
Solution Approach 2:
Multiple battery cells are combined in series connection within a single shrinkable tube housing. The metal plate connects the cells electrically while the shrinkable tube provides unified structural containment. This merging approach consolidates multiple power sources into one integrated module, increasing total output power without proportionally increasing overall complexity.
2Duration of action of moving object
If conventional battery modules are used, then the device is compact, but the use time for emergency calls is short
Solution Approach 1:
The battery module uses multiple cylindrical battery cells arranged in series within the shrinkable tube, allowing extended operational duration through cumulative energy capacity while maintaining a compact form factor that fits within the vehicle's emergency telephone housing.
Solution Approach 2:
The first and second cylindrical battery cells are nested side by side within the shrinkable tube, with the metal plate connecting them in series. This nested arrangement maximizes space utilization, extending use time without significantly increasing the overall volume of the battery module.
3Power
If multiple battery cells are connected in parallel, then the output current increases, but the voltage remains limited and total power output is insufficient
Solution Approach 1:
Multiple battery cells are combined in series connection rather than parallel, increasing the total voltage output while maintaining adequate current capacity. This series arrangement achieves the required 4W or greater power output through voltage multiplication, simplifying the connection structure compared to complex parallel configurations.
Solution Approach 2:
The metal plate serves multiple functions: it provides electrical connection between battery cells in series, provides structural support within the shrinkable tube, and facilitates heat dissipation from the battery cells. This multi-functionality reduces the need for additional components, simplifying the overall connection structure while achieving high power output.
