Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If rigid mounting is used to securely fix cell assembly modules, then mounting reliability is improved, but the battery becomes sensitive to vibrations and shocks
Solution Approach 1:
The patent applies shock-absorbing elements (springs) between the cell assembly modules and the housing to cushion vibrations and shocks before they can damage the battery components. This beforehand cushioning protects the rigidly mounted modules while maintaining mounting reliability.
Solution Approach 2:
The patent changes the mechanical parameters of the mounting system by introducing elastic spring elements that can deform under vibration and shock loads. This allows the mounting system to dynamically adjust its stiffness, maintaining secure fixation while absorbing harmful vibrations.
2Object-affected harmful factors
If shock-absorbing elements are added to reduce vibration sensitivity, then vibration resistance is improved, but device complexity increases
Solution Approach 1:
The patent uses spring elements as flexible mounting components that provide vibration resistance through their elastic deformation. These spring-based flexible mountings absorb shocks while maintaining a relatively simple overall structure compared to complex active vibration control systems.
3Manufacturing precision
If precise dimensional tolerances are maintained during manufacturing, then assembly precision is improved, but manufacturing cost and complexity increase
Solution Approach 1:
The patent introduces dynamic spring elements that can elastically deform to accommodate dimensional variations in cell assembly modules. This dynamic mounting system compensates for manufacturing tolerances automatically, eliminating the need for extremely precise dimensional control during manufacturing.
Solution Approach 2:
The spring mounting system changes the mechanical parameter of stiffness to a variable state, allowing the mounting structure to adapt its dimensions through elastic deformation. This accommodates manufacturing tolerances in cell assembly modules without requiring tight dimensional specifications.

AI summary
An electrical storage battery includes a housing and a plurality of rectangular cell assembly modules electrically coupled together. The rectangular cell assembly modules are mounted by spring damping elements in the housing and are in each case arranged in an intermediate space between an outer area of at least one lower edge of the cell assembly modules and the housing, with at least one common spring damping element extending transversely with respect to the direction of the longest side of the cell assembly modules along the plurality of cell assembly modules.
