Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery cell holding elements lack flexibility and efficiency in adapting to varying geometries and space constraints, particularly in applications like aircraft fuselages, and often result in increased weight and higher production costs.
Innovation Solution
A modular holding element with a receiving section for battery cells and a fixing portion for a holding plate, featuring a round outer contour and latching elements that allow form-fitting fixation, enabling adaptable arrangements and reduced weight through a single injection molding process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional battery cell holding elements are used, then structural stability is maintained, but flexibility in adapting to varying geometries and space constraints is reduced
Solution Approach 1:
The holding element is divided into two functional sections: a receiving section for battery cells and a fixing section for mounting plate attachment. This segmentation allows each section to be optimized independently for its specific function while maintaining overall adaptability.
Solution Approach 2:
The holding element is designed as a universal component that can accommodate different battery cell geometries and arrangements. The receiving section can hold various cell types while the fixing section provides standardized mounting capability, making the element adaptable to multiple applications without requiring custom designs.
2Adaptability or versatility
If modular holding elements are used, then flexibility in arranging battery cells is improved, but manufacturing complexity increases
Solution Approach 1:
The receiving section and fixing section are merged into a single integrated holding element that can be manufactured in one piece using injection molding. This combining approach maintains the modular functionality and adaptability benefits while eliminating the manufacturing complexity of assembling multiple separate components.
3Ease of operation
If multiple separate components are used for holding and fixing, then ease of assembly is improved, but weight increases
Solution Approach 1:
The holding element combines the receiving section and fixing section into a single integrated component manufactured via injection molding. This merger reduces the total number of parts and associated fasteners, thereby reducing weight while maintaining ease of assembly through the simple insert-molding process.
4Manufacturing precision
If traditional production methods are used, then manufacturing precision is maintained, but production costs increase
Solution Approach 1:
The patent replaces traditional mechanical assembly processes with injection molding technology. The holding element is manufactured as a single integrated piece using mold cavities that define the receiving and fixing sections, eliminating the need for separate machining and assembly operations. This substitution maintains precise dimensional control while significantly reducing production costs and complexity.
