Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge is to create a compact fuel cell apparatus that maintains stability and prevents toppling, especially in seismic conditions, while reducing its footprint and size, without compromising its installation stability.
Innovation Solution
The fuel cell apparatus is designed with a gravity center located below half the height of the exterior case, and the position of the gravity center is offset from the center in the width direction to enhance stability, with auxiliary machines and components strategically arranged to achieve this balance, including a heat dissipator at the bottom and a heat-storage tank positioned to lower the center of mass.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the fuel cell apparatus is downsized to reduce footprint, then the size and footprint are reduced, but the installation stability deteriorates and the apparatus may topple
Solution Approach 1:
The patent applies asymmetry by intentionally offsetting the gravity center from the geometric center of the apparatus in the width direction. This asymmetric weight distribution creates a stabilizing effect that prevents toppling, allowing the apparatus to maintain installation stability even when downsized to reduce footprint.
2Volume of moving object
If the fuel cell apparatus is downsized, then the footprint is reduced, but the likelihood of toppling increases
Solution Approach 1:
The patent positions the gravity center asymmetrically, offset from the center in the width direction and below half the height of the exterior case. This asymmetric configuration creates a stabilizing moment that enhances resistance to toppling, ensuring reliable operation even when the apparatus is compact.
