Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional fixing methods are used to fix multiple stacked modules, then the system stability is ensured, but the installation and maintenance convenience deteriorates due to complex fixing procedures
Solution Approach 1:
The fixing structure is segmented into a first fixing member that spans multiple modules and only two end fixing points. This segmentation allows the fixing structure to cover N modules while requiring fixes at only two locations, reducing the complexity of installation and maintenance operations.
Solution Approach 2:
Multiple fixing functions are merged into a single first fixing member that stretches across M modules. Instead of requiring separate fixing operations for each module pair, one fixing member performs the function of securing multiple modules simultaneously, improving operational convenience.
2Reliability
If multiple fixing members are used to fix each module pair, then the system stability is improved, but the number of fixing operations and time required increases
Solution Approach 1:
The first fixing member is designed with multi-functionality, serving to fix multiple module interfaces simultaneously. A single fixing member performs what would traditionally require multiple separate fixing operations, reducing the time required for installation and maintenance while maintaining system stability through its span across M modules.
Solution Approach 2:
The fixing approach transitions from a one-to-one fixing relationship (one fixing member per module pair) to a one-to-many relationship (one fixing member spanning multiple modules). This dimensional change in the fixing structure allows a single component to provide stability across multiple modules, reducing the total number of fixing operations required.

AI summary
A household energy storage system and a module fixing structure thereof are provided. The module fixing structure of the household energy storage system includes multiple modules and at least one first fixing member. The modules are stacked in at least one stacking direction; the first fixing member is configured to stretch across M modules in a stacking direction in which N modules are stacked, and only two ends of the first fixing member are fixed to two of the modules, respectively; N and M each is a positive integer, N is greater than or equal to 3 and M is less than or equal to N-2. In the above module fixing structure, only two modules of the stacked N modules are fixedly connected to the same first fixing member, and the M modules are not fixedly connected to the first fixing member, which reduces the number of fixed connections. Accordingly, the first fixing member stretches across the M modules in the stacking direction in which N modules are stacked, which reduces the number of the first fixing member and reducing the number of fixed connections. Therefore, with the above module fixing structure, the convenience of installation and maintenance is improved.
