Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If traditional battery carriers are used, then manufacturing is simpler, but thermal energy dissipation is insufficient and cell separation is poor
Solution Approach 1:
The carrier is divided into multiple cell bores that physically separate battery cells from each other. Each cell bore acts as an independent compartment, enabling individual thermal management and preventing heat transfer between adjacent cells. This segmentation directly addresses the thermal dissipation issue while maintaining manageable structural complexity.
Solution Approach 2:
Cooling tubes are integrated within the carrier structure, nested inside the cell bores or positioned between them. This nesting approach allows the cooling system to be embedded within the carrier itself, improving thermal management capability without significantly increasing the overall device complexity or external dimensions.
2Adaptability or versatility
If conforming walls are added to accommodate various battery cell shapes, then adaptability improves, but manufacturing complexity increases
Solution Approach 1:
The carrier walls are designed with locally varied geometries that conform to specific battery cell shapes at different positions. Each cell bore can have customized wall contours tailored to the particular cell type it accommodates, while the overall carrier structure remains relatively simple. This localized customization enables high adaptability without requiring complete redesign of the entire carrier.
3Temperature
If cooling tubes are integrated into the carrier, then thermal management improves, but device complexity increases
Solution Approach 1:
The cooling tube system is merged with the carrier structure, integrating thermal management functionality directly into the cell-holding framework. The cooling tubes are positioned to work in conjunction with the cell bores and walls, creating a unified structure that performs both mechanical support and thermal dissipation functions simultaneously, thereby improving cooling efficiency without proportionally increasing complexity.

AI summary
A carrier may include a base with several cell bores, with each cell bore designed to carry a battery cell. The carrier may include several walls, with each wall having one or more surfaces that conform to a shape or surface of the battery cell. For example, a surface of the wall may include an arc with a shape that corresponds to that of a cylindrical battery cell. One of the walls may include opposing surfaces, each of which conform to the shape of multiple battery cells. Also, each cell bore may include a ledge to seat a battery. Additionally, a carrier may include several ribs that provide a vent or channel to direct a gas. In addition to battery cells, carriers may also carry cooling tubes designed to cool the battery cells.
