Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing active material containers in battery housings, such as drying agents in sachets, are loosely positioned, leading to undesirable placement and support issues.
Innovation Solution
An active material container with an air-permeable casing and rim-side guide means, like guide rails, for linear slidable mounting within a battery housing, ensuring secure positioning and support without the need for threads, featuring a lattice-shaped structure for improved air permeability and mechanical stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the active material container is loosely positioned or only jammed in the housing, then the mounting process is simple, but the positioning and support of the active material is undesirable and unreliable
Solution Approach 1:
The patent introduces guide means as an intermediary element between the active material container and the housing. These guide means (guide rails or guide slots) mediate the mounting process by providing a controlled interface that ensures reliable positioning while maintaining ease of assembly. The guide means act as a mediator that translates simple insertion motion into precise, reliable positioning.
Solution Approach 2:
The guide means are pre-configured in the housing before the active material container is inserted. This preliminary arrangement of guiding structures ensures that when the container is inserted, it is automatically guided into the correct position, combining mounting simplicity with positioning reliability without requiring complex fastening operations.
2Reliability
If rim-side guide means are added to the active material container, then positioning and support are improved, but the device complexity increases
Solution Approach 1:
The guide means are segmented into discrete, modular elements (such as separate guide rails or integrated guide slots) that can be independently manufactured and assembled. This segmentation allows the complex positioning function to be achieved through simple, standardized components rather than a monolithic complex structure.
Solution Approach 2:
The guide means serve multiple functions simultaneously: they guide the insertion motion, provide positioning reference, support the active material container, and prevent unwanted movements. This multi-functionality reduces the need for additional separate components, thereby limiting the increase in device complexity while achieving reliable positioning.
3Object-affected harmful factors
If the casing is configured with lattice-shaped wall sections, then air permeability is improved, but mechanical strength may be reduced
Solution Approach 1:
The patent employs lattice-shaped wall sections that create a porous structure with controlled void ratios. This porous configuration allows air to pass through the casing walls while the remaining material provides structural support. The lattice geometry optimizes the balance between permeability and strength by distributing loads across the framework while maintaining open channels for air flow.
Solution Approach 2:
The lattice-shaped wall sections can be constructed using composite materials or material composites that combine different properties in a single structure. This allows the casing to achieve both the air permeability required for active material function and the mechanical strength needed for structural integrity through the synergistic combination of materials with complementary properties.

AI summary
An active material container for a functional housing has an air-permeable casing with an interior and an active material arranged inside the interior. One or more rim-side guide elements are arranged at the air-permeable casing and are provided to linearly slidably guide the active material container in an insertion direction in corresponding guide elements of a receptacle of the functional housing. The functional housing is preferably a battery housing.
