Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If beams are connected using traditional connection methods, then the battery case structure can be formed, but the assembly process is complex and prone to errors
Solution Approach 1:
The connecting piece is inserted into a groove formed on the side beam, creating a nested connection structure where one component fits within another. This simplifies the assembly process by eliminating complex fastening operations while maintaining structural integrity of the battery case frame.
Solution Approach 2:
The groove structure on the side beam automatically guides and positions the connecting piece during assembly, enabling self-alignment and reducing assembly errors. The connection structure serves itself by incorporating positioning features that eliminate the need for additional alignment tools or procedures.
2Stability of the object's composition
If beams are connected with fixed rigid structures, then structural stability is achieved, but flexibility in assembly and disassembly is reduced
Solution Approach 1:
The battery case frame is divided into modular components (side beams, intermediate beams, and connecting pieces) that can be independently assembled and disassembled. The groove-based connection allows these segments to be easily connected and separated while maintaining structural stability during operation.
Solution Approach 2:
The connection structure transitions from a static rigid joint to a dynamic assembly system where the groove and inserting piece allow for easy assembly and disassembly operations. This dynamic design enables the structure to be configured flexibly while maintaining stability when assembled.
3Strength
If traditional connection methods are used, then beams can be joined, but damage may occur during assembly due to improper alignment
Solution Approach 1:
The groove is pre-formed on the side beam with precise dimensions and positioning features before assembly. This preliminary preparation ensures that the connecting piece aligns correctly during assembly, preventing misalignment damage while maintaining connection strength.
Solution Approach 2:
The groove structure acts as a protective feature that cushions and guides the connecting piece during insertion, preventing impact damage and misalignment. The pre-designed groove geometry ensures gentle engagement that protects both components from assembly-related damage.

AI summary
The invention discloses a battery case and a battery device. An intermediate beam is connected to at least one side beam by a connecting piece, and a first groove is disposed on a side beam corresponding to a reference end. After the connecting piece is accommodated in the first groove, the intermediate beam and the corresponding side beam can be fixed and connected. Accordingly, the effective connection between the intermediate beam and the side beams is implemented, damage to the intermediate beam and the side beams in the connection process is prevented, and meanwhile the effects of the connection on the single batteries can be prevented, thereby improving the reliability of the battery device.
