Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If conventional fixing manners are used to fix stacked modules, then the stability of the system is ensured, but the complexity of installation and maintenance increases
Solution Approach 1:
The patent merges multiple fixing functions into a single fixing member that can fix multiple modules simultaneously. The fixing member is designed to span across multiple modules and secure them together, reducing the number of separate fixing operations needed and simplifying the overall fixing process while maintaining system stability.
Solution Approach 2:
The fixing member is designed with multi-functionality to perform multiple fixing tasks across different modules. It can be used to fix various types of modules (energy storage modules, battery modules, etc.) in different stacking configurations, making the fixing system versatile and reducing the need for specialized fixing components for each module type.
2Stability of the object's composition
If multiple fixing connections are made across stacked modules, then the stability is improved, but the time required for installation and maintenance increases
Solution Approach 1:
The patent combines multiple fixing operations into a single integrated fixing member that secures multiple modules simultaneously. This reduces the sequential steps required for installation and maintenance, significantly decreasing the time needed while maintaining adequate module stability through the distributed fixing points along the fixing member.
Solution Approach 2:
The fixing member is designed to span across more modules than the minimum required for stability (stretching across M modules where M ≤ N-2). This excessive coverage provides additional stability margins and allows for quicker installation by reducing the need for precise positioning and multiple adjustment operations.
3Reliability
If conventional fixing methods are used, then adequate fixation is achieved, but the adaptability to different installation environments is reduced
Solution Approach 1:
The fixing member is designed as a universal component that can adapt to different installation environments and module configurations. It can be applied to various stacking arrangements (vertical, horizontal, mixed), different module types, and different installation locations, maintaining reliable fixation across diverse scenarios without requiring environment-specific customization.
Solution Approach 2:
The fixing system incorporates dynamic characteristics by allowing the fixing member to span across variable numbers of modules (M modules where M ≤ N-2) based on installation requirements. This flexibility enables adaptation to different installation environments while maintaining reliable fixation through adjustable spanning configurations.

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 stretches 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.
