Exhaust Purification Filter Layout for Easy Replacement Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing exhaust gas purification apparatuses have limited accessibility to filters, leading to increased worker fatigue during replacement and lack flexibility in installation due to compact designs and varying installation spaces.
Innovation Solution
An exhaust gas purification apparatus with a body featuring an opening area, intake and discharge parts spaced apart with a filter at the center, and a body cover allowing easy access for filter replacement, along with a selective reduction catalyst and injection part for nitrogen oxide reduction, and a coolant tank for cooling, enabling flexible installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the exhaust gas purification apparatus uses a compact design, then the device size is reduced, but the accessibility to filters for worker replacement deteriorates
Solution Approach 1:
The exhaust gas purification apparatus is divided into a body and a body cover that can be separated. The body cover is detachably coupled to the body, creating an opening area that allows workers to easily access and replace the filter without disassembling the entire device. This segmentation maintains compact overall size while providing easy maintenance access.
2Device complexity
If the exhaust gas purification apparatus has a fixed single body arrangement, then the internal component layout is simplified, but the flexibility in installation space arrangement deteriorates
Solution Approach 1:
The exhaust gas purification apparatus employs asymmetric design in the body cover coupling structure, allowing the device to be installed in various orientations (upright, inverted, sideways) while maintaining proper internal component alignment. The opening area and body cover are positioned to accommodate different installation configurations without requiring changes to the internal component layout.
3Volume of stationary object
If the filter is positioned deep inside the body, then the internal space utilization is improved, but the ease of filter replacement deteriorates
Solution Approach 1:
The filter is extracted from a deeply embedded position and repositioned to be disposed inside the body but accessible through the opening area created by the detachable body cover. This allows the filter to be easily removed and replaced by workers without requiring disassembly of the entire apparatus, while still maintaining efficient internal space utilization.
