Fuel Cell Module Sliding Shelf for Compact Service Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fuel cell vehicles face challenges in easily replacing or repairing compactly accommodated electric parts such as the fuel cell stack, PMC, BOP, and cooling system, due to their fixed positions within the vehicle.
Innovation Solution
A fuel cell power generation module with an accommodation frame and sliding shelves that support electric parts, allowing them to be extracted forward for easy replacement or repair, featuring rail portions, sliding portions, and shelf legs with adjustable height and rotation mechanisms for stable support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If electric parts are compactly accommodated in fixed positions, then space utilization is improved, but ease of repair and replacement deteriorates
Solution Approach 1:
The shelf is designed with sliding portions that engage with rail portions, allowing the shelf to move dynamically between a retracted position (for compact accommodation) and an extracted position (for easy access to electric parts). This dynamic mechanism resolves the contradiction by enabling both compact space utilization and ease of repair/replacement through controlled movement.
2Ease of repair
If electric parts are made extractable for repair, then ease of repair is improved, but device complexity increases
Solution Approach 1:
The extraction mechanism is segmented into discrete components: sliding portions on the shelf, rail portions on the accommodation frame, and guide handles. This segmentation allows the complexity to be distributed across simple, independent elements rather than requiring a complex integrated system, thereby improving ease of repair while minimizing overall device complexity.
3Stability of the object's composition
If shelf legs are added for stable support during extraction, then stability is improved, but device complexity increases
Solution Approach 1:
The shelf legs are designed to be nested within the shelf structure when not in use, and deployed outward when extraction is needed. This nesting approach provides stable support during extraction while minimizing the increase in device complexity by integrating the support function into the existing shelf geometry rather than adding completely separate support structures.
