Energy Storage Box Mounting Post Layout for Higher Case Rigidity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing energy storage cases suffer from poor structural strength, leading to deformation when an energy storage unit is mounted, which affects the service life of the case.
Innovation Solution
The energy storage case design includes a mounting post supported between a mounting beam and a plate-shaped bottom wall, with ends fixedly connected to both, enhancing structural strength and reducing deformation risk.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If mounting posts are simply installed in the case body without proper support structure, then the device complexity is reduced, but the structural strength deteriorates causing case deformation
Solution Approach 1:
The case body is segmented into functional regions including a mounting space, a first space above it, and a second space below it. The mounting beam is positioned in the first space while mounting posts extend through to the second space, creating distinct functional zones that distribute structural loads and reduce overall complexity.
Solution Approach 2:
The mounting beam is positioned above the mounting space in the height direction, creating a three-dimensional support structure. This vertical arrangement allows the mounting posts to be supported at multiple levels (top by mounting beam, bottom by case body), enhancing structural strength without increasing planar complexity.
2Ease of manufacture
If the case body structure is simplified for ease of manufacture, then the ease of manufacture is improved, but the structural strength deteriorates leading to deformation risk
Solution Approach 1:
The case body is divided into distinct spaces (mounting space, first space, second space) with the mounting beam positioned in the first space. This segmentation allows each component to be manufactured and assembled separately, improving ease of manufacture while maintaining structural integrity through the distributed support system.
Solution Approach 2:
By positioning the mounting beam in the first space above the mounting space and supporting mounting posts vertically from this elevated position down to the second space, the structure gains three-dimensional stability. This vertical support arrangement enhances structural strength without complicating the manufacturing of individual components.
3Duration of action of stationary object
If mounting posts are not properly supported, then the device complexity is reduced, but the service life deteriorates due to case deformation
Solution Approach 1:
The case body is segmented into functional zones with the mounting beam positioned in the first space above the mounting space. This segmentation creates a dedicated support structure that isolates the mounting function from the case body, preventing deformation and extending service life without significantly increasing overall structural complexity.
Solution Approach 2:
The mounting beam is positioned above the mounting space in the height direction, creating vertical support for mounting posts. This three-dimensional arrangement distributes mechanical loads along the height of the case, preventing deformation that would reduce service life, while maintaining relatively simple horizontal footprints.
