Extruded Seal Storage Device with Nested Annular Hub
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing storage and transport devices for extruded continuous seals in motor vehicles are inefficient in managing the winding stress and volume optimization, leading to potential damage and increased storage costs due to the need for significant force to disassemble stacked devices.
Innovation Solution
A device featuring a horizontal tray and a vertical axis hub with a frustoconical shape, where the peripheral wall and hub form an annular space for seal storage, allowing for partial support on the tray and peripheral wall, enabling stackability and reducing winding stress through the arrangement of seal portions and the use of movable feet for easy handling and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of stationary object
If devices are stacked vertically for storage, then storage volume is optimized, but significant force is required to disassemble the stacked devices
Solution Approach 1:
The device employs a nested configuration where the peripheral wall is positioned inside the hub structure, allowing multiple devices to be stacked vertically one inside another. This nesting arrangement optimizes storage volume by minimizing the footprint of stacked devices while the modular nested design enables easy separation without requiring excessive force.
2Reliability
If the peripheral wall extends around the hub to retain the seal, then seal retention is improved, but device complexity increases
Solution Approach 1:
The peripheral wall and hub are merged into a single integrated structural unit, where the peripheral wall extends around the hub to form a cohesive assembly. This merging provides effective seal retention while avoiding the complexity of separate retaining mechanisms, as the structural elements work together as one unified component.
3Strength
If the seal is wound around the hub with support on the tray and peripheral wall, then winding stress is minimized, but the device requires more space for proper seal arrangement
Solution Approach 1:
The seal is arranged in a three-dimensional configuration within the annular space defined by the hub and peripheral wall, utilizing vertical and radial dimensions. This spatial arrangement minimizes winding stress on the seal by distributing it across multiple dimensions while optimizing the use of available device volume, preventing both excessive stress and unnecessary space consumption.
