Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If more parts and components are added to improve safety and power integration efficiency, then the battery energy storage device can meet higher requirements, but the assembly becomes more complicated and device complexity increases
Solution Approach 1:
The support structure is integrated with the protective tray to form a unified component that provides both structural support and protection functions simultaneously, reducing the number of separate parts and simplifying assembly while maintaining safety requirements
Solution Approach 2:
The support structure serves multiple functions including mechanical support, protection of battery cells, and integration with thermal management channels, eliminating the need for separate dedicated components and reducing overall device complexity
2Reliability
If a protective tray is used to protect the battery module, then the cell set is protected, but the device complexity increases and manufacturing cost increases
Solution Approach 1:
The protective function is merged into the support structure itself, which is formed integrally with the structure body, eliminating the need for a separate protective tray while maintaining protection capabilities
Solution Approach 2:
The support structure is made from aluminum alloy material that provides both structural integrity and protective capabilities, combining multiple functions in a single composite component that reduces overall complexity
3Ease of manufacture
If the structure body and support are formed separately and then assembled, then manufacturing flexibility is improved, but manufacturing precision requirements increase and assembly complexity increases
Solution Approach 1:
The structure body and support are formed as an integral structure through extrusion processing, eliminating the need for separate assembly operations and reducing precision requirements while maintaining manufacturing flexibility through modular design of the extrusion process

AI summary
A battery energy storage module and a battery energy storage device. The battery energy storage module comprises: a structure body (101), a support member (102), and a cell group (103). A cavity for accommodating the cell group (103) is formed inside the structure body (101). The structure body (101) is provided with an opening. The cell group (103) is disposed in the cavity of the structure body (101) through the opening of the structure body (101). The support member (102) is used for supporting the structure body (101) to protect the cell group (103) disposed in the cavity of the structure body (101). Because the support member (102) is used for supporting the structure body (101) to protect the cell group (103) disposed in the cavity of the structure body (101), the battery energy storage module can have strong impact resistance, and can be applied to a full vehicle environment alone without being disposed in a protection tray.
