Prismatic Housing Support Structure Without Welded Load Interfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing housings for energy storage devices lack durability due to bearing forces being transmitted through interfaces like welds, which are prone to failure.
Innovation Solution
A housing design featuring prismatic elements with integrated support sections and threaded bores that directly support bearing forces, eliminating the need for welds and enhancing structural integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If bearing forces are transmitted through welds connecting housing elements, then the housing can be assembled, but the durability decreases due to interface failure risk
Solution Approach 1:
The support section is integrated directly into the housing element as a single monolithic structure, eliminating the interface between separate components. This merging of the support function into the housing element itself removes the weld joint that was previously a weak point, thereby improving reliability without compromising strength.
2Strength
If additional interfaces like welds are used to connect bearing elements, then the housing can be assembled, but the structural integrity decreases
Solution Approach 1:
The support section is merged with the housing element to form an integrated structure, reducing the number of separate interfaces. This integration maintains structural integrity by eliminating weak weld joints while simplifying the overall device complexity through component consolidation.
Solution Approach 2:
The welding process and associated interfaces are extracted from the design by using a monolithic support section that requires no additional joining methods. This removal of the welding step simplifies the assembly process and eliminates the structural weakness introduced by thermal joining.
3Reliability
If threaded bores are arranged in the support plane, then bearing forces are directly supported, but manufacturing precision requirements increase
Solution Approach 1:
The threaded bores are pre-positioned and integrated into the support section during the extrusion or molding process, rather than being added as separate machining operations. This preliminary integration ensures precise positioning relative to the support plane while reducing the need for high-precision post-manufacturing operations.
