Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing containment apparatuses for battery tray racks in battery manufacturing lack a cushioning mechanism, leading to uneven force distribution and potential damage during battery inflation, and result in increased costs and reduced service life due to material fatigue from concentrated stresses.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the screw and battery partition plates are made with sufficient structural strength to withstand battery inflation forces, then the reliability of the containment apparatus is improved, but the device complexity and cost increase due to larger component sizes
Solution Approach 1:
The containment apparatus is divided into multiple independent clamping units, each with its own screw and partition plate assembly. This segmentation allows each component to be optimized for standard loads rather than requiring all components to withstand maximum inflation forces, reducing overall complexity while maintaining reliability through distributed load bearing.
Solution Approach 2:
The patent introduces cushioning elements positioned between the screw/battery partition plate assembly and the battery tray rack. These cushioning components absorb and distribute the inflation forces before they reach the structural members, preventing stress concentration and allowing the use of smaller, less complex components while maintaining system reliability.
2Strength
If the screw and battery partition plates are made with sufficient structural strength to prevent damage during battery inflation, then the strength of the containment apparatus is improved, but the manufacturing cost increases due to larger and more robust components
Solution Approach 1:
Cushioning elements are incorporated into the clamping units to absorb and distribute inflation forces. This cushioning mechanism protects the screw and battery partition plates from peak stresses, allowing these components to be manufactured with standard dimensions and materials rather than requiring oversized, high-strength components, thereby reducing manufacturing costs while maintaining adequate strength.
Solution Approach 2:
The patent modifies the mechanical parameters of the system by introducing compliant cushioning elements that change the stress distribution pattern. This parameter change allows the rigid components (screw and partition plates) to operate within lower stress ranges, enabling the use of standard-gauge materials and reducing manufacturing costs while maintaining sufficient strength for the application.
3Reliability
If the screw and battery partition plates are designed to repeatedly withstand large stresses during containment operations, then the reliability of the containment apparatus is improved, but the service life of these components decreases due to material fatigue
Solution Approach 1:
The cushioning elements serve as a protective interface that absorbs shock and distributes cyclic loading forces. By cushioning the impact and spreading the stress over a larger area and longer duration, these elements significantly reduce the peak stresses and stress concentrations that cause fatigue in the screw and battery partition plates, thereby extending their service life while maintaining containment reliability.
Solution Approach 2:
The cushioning elements act as an intermediary between the rigid clamping components and the battery tray rack. This intermediary layer decouples the rigid components from direct contact with the deformable battery pack, mediating the stress transmission and reducing fatigue loading on the screw and partition plates, which enhances their durability and service life.

AI summary
A containment apparatus for battery tray rack includes a pressing module, a securing module, and a controller. In response to that the containment apparatus is to form the containment on the battery tray rack, the controller controls the pressing module to apply a compressive force, so that the battery tray rack withstands a clamping pressure, and the controller controls the securing module to lock the battery tray rack to maintain the clamping pressure. In response to that the containment apparatus is to release the containment from the battery tray rack, the controller controls the pressing module to apply the compressive force, and the controller controls the securing module to unlock the battery tray rack, and then the controller controls the pressing module to cancel the compressive force.
