Solution Overview
Problem
Existing battery racks lack sufficient seismic performance while maintaining weight and cost efficiency, as conventional methods of enhancing seismic performance often increase weight and production costs.
Innovation Solution
A battery rack design featuring a base plate, main frame, top plate, and wall mount member with X-shaped beads and 'S' cross-section vertical beams, along with an elastic wall mount member, to enhance seismic performance without increasing weight, using a geometric structure that distributes stress effectively and reduces material usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a frame is manufactured with a metal alloy material having high strength or is increased in thickness, then seismic performance is improved, but weight is increased and production costs are not economical
Solution Approach 1:
The patent applies curved surface structures to the frame members, replacing traditional straight linear designs. The curved surfaces distribute stress more effectively throughout the structure, enhancing seismic performance without requiring increased material thickness or weight. This geometric optimization allows the frame to maintain structural integrity under seismic loads while keeping the weight and material usage economical.
2Strength
If a strength reinforcing material is added to the battery rack, then seismic performance is improved, but space efficiency is reduced and production costs are not economical
Solution Approach 1:
Instead of adding separate reinforcing materials, the patent integrates strength enhancement directly into the frame members through curved surface geometries. This approach maintains structural simplicity and space efficiency while achieving improved seismic performance through optimized stress distribution in the curved surfaces.
Solution Approach 2:
The curved surface structures are strategically positioned on frame members to provide localized strength enhancement where seismic stresses are most critical. This allows the structure to achieve high seismic performance without uniformly increasing complexity throughout the entire battery rack.
3Strength
If conventional frame structures are used, then production costs are reduced, but seismic performance is insufficient
Solution Approach 1:
The curved surface structures can be manufactured using standard fabrication techniques such as bending, rolling, or forming processes. These methods are well-established in metal fabrication and do not require specialized equipment or complex manufacturing procedures, thereby maintaining ease of manufacture and cost-effectiveness while significantly improving seismic performance.
