Electric Storage Frame Holding Part Projections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In electric storage apparatuses, external forces can cause deformation leading to gaps between frame elements and storage devices, resulting in unintended movement and positional variations of the storage devices, which can apply uneven loads to connected members.
Innovation Solution
Incorporating a holding part with projections between the second frame element and the electric storage devices, these projections are in contact with the devices to prevent movement by applying a force that aligns their positions and absorbs excessive force, ensuring proper alignment and distribution of loads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If frame elements directly abut electric storage devices, then structural simplicity is maintained, but gaps occur due to deformation causing device movement and positional variation
Solution Approach 1:
A holding part with projections is introduced as an intermediary component between the second frame element and the electric storage devices. The projections extend in the second direction and contact the devices, preventing gaps and movement while maintaining overall structural simplicity. This mediator absorbs deformation effects and maintains reliable positioning.
2Reliability
If frame elements are rigidly connected to electric storage devices, then positional stability is ensured, but load cannot be distributed during deformation
Solution Approach 1:
The holding part is segmented into multiple projections that individually contact different electric storage devices. This segmentation allows each projection to independently maintain contact and distribute loads, while collectively providing stable positioning for all devices in the assembly.
3Manufacturing precision
If holding part with projections is added, then device movement is prevented and positioning is improved, but frame structure complexity increases
Solution Approach 1:
The holding part with projections is applied locally at specific positions where devices require stabilization, rather than modifying the entire frame structure. The projections are strategically positioned to contact devices only where needed, providing precise alignment control without unnecessarily complicating the overall frame design.
