Prismatic Housing Support Structure That Bypasses Weld Seam Loads
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing housings for energy storage devices face durability issues due to bearing forces acting on weld seams, which are stressed and prone to failure.
Innovation Solution
A housing design featuring prismatic elements with integrated support sections and threaded bores aligned parallel to support planes, allowing direct support via screws, eliminating the need for weld seams and enhancing durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If bearing forces are transferred through weld seams, then the housing can be assembled, but the durability decreases due to stress on weld seams
Solution Approach 1:
The patent removes the weld seams from the force transmission path by introducing threaded bores that extend through the support sections. The bearing forces are now transferred through screws engaged in these threaded bores rather than through weld seams, eliminating the stress concentration and failure risk associated with welded joints.
Solution Approach 2:
The threaded bores act as intermediaries between the support sections and the mounting structure. Instead of directly welding supporting elements to the housing, the patent uses threaded bores as a mediating structure that allows screw-based attachment, distributing stresses more evenly and avoiding weld seam failure.
2Reliability
If threaded bores are arranged parallel to support planes, then bearing forces are directly supported improving durability, but manufacturing complexity increases
Solution Approach 1:
The threaded bores are pre-formed in the support sections during the housing manufacturing process, with their axes oriented parallel to the support planes. This preliminary arrangement ensures that when supporting elements are later attached with screws, the bearing forces are automatically directed along the optimal path through the support planes, maximizing durability without requiring complex post-assembly adjustments.

A housing including: a first housing element, which extends in the form of a prism along a longitudinal axis, where the housing element has a first side wall and a second side wall, between which a support section extends, which spans a first support plane (E_T2), and a second housing element, which is connected to the first housing element in such a way that a first housing chamber is bounded by the first housing element and the second housing element, where a supporting element for supporting the housing relative to an adjacent element can be connected to the first housing element via a first screw, and where the first screw engages in a threaded bore of the first housing element, the threaded bore is arranged at least partially in the first support plane and a bore axis of the threaded bore is arranged parallel to the first support plane.
